The City of Placentia has budgeted in its Capital Improvement Program to replace the Golden Avenue Bridge and the related portion of the OC Bikeway Loop Segment D. The bridge is located along Golden Avenue west of Imperial Highway and East of Valencia Avenue. A total of $2,647,046 of Federal Highway Bridge Program Funding and $2,200,000 of Community Project Funding/Congressionally Directed Spending has been allocated for the construction phase. Included in the scope of work for this project is the completion of a portion of OC Bikeway Loop Segment D that's within the construction zone of the bridge. The City processed a cooperative agreement on October 2, 2019, which was amended on August 8, 2023, with the County of Orange for the contribution of funds towards the construction of their facility in the amount of $215,682.

The City solicited competitive bids for the project. A total of four (4) bids were received on October 16, 2025. These bids consisted of two portions: Bid “A” + Additive Bid “B”. Bid "A" is the base bid, which entails demolition and construction of the bridge. Bid "B" is for work 1 related to the OC Bikeway Loop Segment D. The grand total of all bids was used as the basis for determining the low bid for this project. The contract will be for the amount represented by the sum of Bid "A" and Additive Bid "B". The low bid received from CT&T Concrete Paving Inc., was found to be the lowest responsive and most responsible bid received. Staff recommends that City Council award a construction contract to CT&T Concrete paving in the amount of $4,687,010.50.

In addition to the construction cost, a ten percent (10%) construction contingency amount of $468,701.05 is provided to cover any unforeseen conditions found during construction.

The City also solicited a request for competitive proposals from qualified construction management and inspection firms to provide all required construction management and inspections services needed to deliver the project and ensure compliance with Caltrans funding requirements. After the proposal review process the committee found T.Y. Lin International submitted the most qualified proposal.

The City is also recommends amending the contract with Biggs Cardosa and Associates, the design engineering firm responsible for preparing the project plans and specifications, to include construction engineering support services.

The total construction contract cost, including contingency, construction engineering and construction management and inspection amounts to $6,037,599.55.

Recommendation:

1. Approve the Plans and Specifications prepared by Biggs Cardosa and Associates for the Golden Avenue Bridge Replacement Project, City Project No. 1801; and

2. Approve a Public Works Agreement with CT&T Concrete Paving for the Golden Avenue Bridge Replacement Project in the amount of $4,687,010.50; and

3. Reject all other bids received and authorize return of the bid bonds; and

4. Authorize the City Administrator to approve contract change orders up to ten percent (10%) of the contract amount, or $468,701.05, for a total construction contract not-to- exceed amount of $5,155,711.55; and

5. Approve a Professional Services Agreement with T.Y. Lin to provide construction management and inspection services for a not to exceed amount of $713,091.00; and

6. Approve Amendment No. 6 to the Professional Services Agreement with Biggs Cardosa and Associates for an additional $168,797 to provide additional professional services for construction engineering support for a cumulative contract not-to-exceed amount of $1,139,735 and extend the term of the contract by an additional 12 months; and

7. Authorize the City Administrator and/or her designee to execute all necessary documents, in a form approved by the City Attorney.

Strategic Plan Statement:

This item is not directly related to a specific strategic plan goal.

Discussion:

The City of Placentia has budgeted in its Capital Improvement Program to replace the Golden Avenue Bridge and the related portion of the OC Bikeway Loop Segment D. The bridge is located along Golden Avenue west of Imperial Highway and East of Valencia Avenue. Golden Avenue is a regionally significant collector roadway, providing east -west travel between the cities of Placentia and Yorba Linda. The bridge was built in 1934 to span the Carbon Canyon 2 Channel and was rated functionally obsolete in 2005 by Caltrans.

The existing bridge is an earth-filled reinforced concrete arch bridge supported on spread footings. The bridge is 34 feet long and 27 feet wide and carries two lanes of traffic over the channel. There are currently no sidewalks or bicycle lanes on the bridge resulting in potential conflicts between pedestrians, bicyclists and motorists.

The proposed bridge will be a 60 feet 4 inch wide structure designed to improve safety, mobility, and connectivity. The bridge will provide two 12 feet wide travel lanes and 6 feet wide sidewalks on both the south and north sides of the structure. The superstructure will consist of PC/PS CA I54 girders and will incorporate a Type 732SW(Modified) barrier to meet current safety standards. It is also designed to accommodate six telecommunications conduits, a 4 inch So Cal Gas line, six conduits for Southern California Edison (SCE), and a 16 inch casing for a future Yorba Lind Water District waterline. The substructure will be composed of abutments with a thickness of 3.5 feet, supported on 2.5 feet CIDH piles. In addition, the project will also complete 800 feet of Orange County Public Works' bike/pedestrian trail project, OC Loop Segment D, from Station 21+00 to 29+00, which runs directly under the bridge, providing a link for regional trail connectivity.

A total of $2,647,046 of Federal Highway Bridge Program Funding and $2,200,000 of Community Project Funding/Congressionally Directed Spending has been allocated for the construction phase. The City processed a cooperative agreement on October 2, 2019, which was amended on August 8, 2023, with the County of Orange for the contribution of funds towards the construction of their facility in the amount of $215,682. To cover the required

11.47% Local Match and difference between available grant funds and total project cost, the City is allocating $974,871.55 of local Measure U Funds.

On October 16, 2025 the City received four (4) bids from contractors. The following table provides the total bid amounts received from each contractor. These amounts reflect base bid "A" and additive bid "B", which form the basis of award:

Contractor Bid Amount
CT&T Concrete Paving Inc. $4,687,010.50
Beador Construction Company Inc. $4,967,400.00
Los Angeles Engineering, Inc. $5,453,000.00
Toro Enterprises, Inc $6,001,127.00

After reviewing the bids, it was determined that CT&T Concrete Paving Inc. submitted the lowest responsible bid. Upon review and analysis, Staff determined the bid proposal to be responsive and valid. Based upon CT&T's reference check, and submitted bid, Staff recommends awarding a construction contract to CT&T Concrete Paving Inc., for the Golden Avenue Bridge Replacement Project.

A component of this project requires the allocation of funding for construction management and inspection services. Staff prepared a Request For Proposals (RFP) for Construction Management and Inspection Services. The City received seven proposals from qualified firms.

Staff reviewed the submitted proposals and the cumulative composite score for the firm’s proposal is noted below:

3 Consultant Score
T.Y. Lin International 95.2
Berg & Associates, Inc.93
SYRUSA Engineering 90.3
Southstar Engineering & Consulting, Inc.87.3
Z&K Consultants 86
SPECS Engineering Group 82.7
Fountainhead Consulting Corporation 80.7

Staff recommends awarding the contract to T.Y. Lin International. T.Y. Lin has extensive experience and expertise in providing professional construction management and inspection services for bridge improvement projects. They have experience with Caltrans Local Assistance which will benefit the City in receiving reimbursements from Caltrans once the project enters the construction phase. The term of the proposed Professional Services Agreement will be for a total of 36 months from November 18, 2025, to November 18, 2028 in the amount of $713,091.

Staff also recommends amending the contract with Biggs Cardosa and Associates, the design engineering firm responsible for preparing the project plans and specifications, to include construction engineering support services. Biggs Cardosa has proved essential in completing the construction documents in compliance with all Caltrans standards. Their technical assistance will be needed during the construction phase to respond to questions from the contractor as well reviewing material submittals to ensure compliance with contract documents.

Fiscal Impact Summary:

The total construction cost for the Golden Avenue Bridge Replacement Project amounts to $6,037,599.55. This cost consists of the bid amount submitted by CT&T Concrete Paving Inc., Company in the amount of $4,687,010.50, a construction contingency in the amount of $468,701.05, construction management and inspection services with T.Y. Lin in the amount of $713,091 and construction engineering support services in the amount of $168,797.

77 Subject: Professional Construction Management and Inspection Services for the Golden Avenue Bridge Rehabilitation Project & Orange County Bikeway Loop Segment D from Station 21+00 North of Golden Avenue to Station 31+00 South of Golden Avenue
Dear Mr. Guerrero-Gabany,
T.Y. Lin International (TYLin) is excited to collaborate with the City of Placentia (City) to provide Professional Construction Management (CM) and Inspection Services for the Golden Avenue Bridge Rehabilitation Project & Orange County Bikeway Loop Segment D from Station 21+00 North of Golden Avenue to Station 31+00 South of Golden Avenue (Project).

TYLin has the expertise to make this project a success, with the main goal to deliver the project within budget, schedule and minimize community impact. We have a long history of working with local agencies on California Department of Transportation’s (Caltrans) federally-funded bridge projects and have assembled a team of highly experienced professionals to deliver effective CM services. Under the City’s direction, we are prepared to provide comprehensive planning including a full constructability review, regular and meaningful schedule review, and proactive partnering with the Contractor.

The following pages demonstrate these strengths consistently through our project experience and in our proposed key staff.

TYLin’s Principal-in-Charge, Joseph Smith, PE, CCM, began his career with Caltrans Structures Construction working in District 7. He has continued as a consultant providing inspection, CM and project management services to Caltrans and numerous other agencies throughout Southern California. His “client-first” approach is demonstrated by his regular outreach to clients to assess their satisfaction with on- site staff. His extensive project-specific experience and understanding of construction issues will provide an experienced resource for any project issue that may arise.

The experienced and qualified TYLin Team will be led by Resident Engineer/ Structures Representative, Mazen Mneimneh PE, QSD, who will be the City’s primary point of contact and will manage all aspects of the project. His understanding of the various structures components along with required coordination with the United States Army Corps of Engineers (USACE), Los Angeles County Flood Department (LACFCD) and other key stakeholders make him an excellent choice for this project. Mazen brings more than 25 years of CM and engineering experience, specializing in public works construction. He has successfully delivered 10 bridge projects over the past decade, including five federally funded through the Highway Bridge Program (HBP), further detailed in his resume. Mazen will lead a team of experienced construction professionals, who are fully capable to provide any CM, oversight, materials testing and other services that are required to successfully complete this project.

Structural Inspector, Ali Habibi, will work closely with Mazen in the field. His experience includes numerous similar projects such as the OC Loop Carbon Creek Channel Segment D Bikeway Gap Closure with the County of Orange and the Higuera Street Bridge Replacement Project (HBP) with Culver City where he worked directly

Principal in Charge | 25% Available
Joseph has 34 years of civil engineering experience in public works construction, managing structures, interchanges, utility, and roadway projects. As Project Manager, Joseph has managed more than one dozen HBP-funded projects. He has extensive experience in management and training of representatives and organizing and leading meetings. He is responsible for providing oversight and support and has worked closely with state, federal, and local agency managers to satisfy staffing requests in a timely manner, while controlling and monitoring costs. Joseph formerly worked for Caltrans OSC in Los Angeles.

EXPERIENCE
City of Los Angeles Bureau of Engineering, Sixth Street Viaduct Replacement (CM/GC Delivery) | Los Angeles, CA Project Manager for this $450M CMGC bridge replacement project. Joseph supported TYLin staff and communicated directly with City staff, assuring all project needs were met. He was also responsible for monitoring the project budget and preparing monthly estimates. The project included a 2,864 foot long network tied-arch continuous concrete viaduct bridge, combined with a 193-foot-long post- tensioned CIP reinforced concrete box girder structure at the west approach. The multi-year project utilized the CMGC delivery method. The previous Sixth Street Viaduct was constructed in 1932, using reinforced concrete with distinctive T-beam/ steel arch support at the center spans. This structure had been an important landmark, connecting downtown Los Angeles and the arts district in Boyle Heights, spanning the Los Angeles River and State Route 101. In 1986, the Sixth Street Viaduct was found to be eligible for inclusion in the National Register of Historic Places. Over the years, the concrete has deteriorated due to Alkali Silica Reaction. As a result of the deterioration, the structure had been determined to be structurally unable to withstand a moderate earthquake and needs retrofit or replacement. The project also included improvements to local intersections to facilitate improved traffic flows, and the development of local parks and greenbelts to beautify this industrial area. The project site challenges included downtown traffic, working within the Los Angeles River, working over and under very active rail lines operated by five different agencies, dealing with right-of-way challenges, and managing numerous identified and unidentified utility conflicts.

City of Los Angeles Bureau of Engineering, North Atwater Non-Motorized Multi-Modal Bridge | Los Angeles, CA Project Manager for a task to provide design and construction engineering for a new multi-modal bridge across the Los Angeles River. The new cable-stayed bridge is 325 feet long, 35 feet wide, and has two separate paths to accommodate equestrians and pedestrians/bicyclists. The project required a single concrete pier in the river and two abutments on each end of the bridge. Joseph communicated directly with the City staff assuring all project needs were met. He was also responsible for monitoring the project budget and prepared monthly estimates.

City of Cathedral City, Cathedral Canyon Drive Bridge over Coachella Valley Water District (CVWD) Stormwater Channel | Cathedral City, CA Project Manager supporting the Resident Engineer and the CM team for the construction of a 5-span cast-in-place (CIP) box girder bridge over CVWD’s Stormwater Channel, known as The Whitewater River. The improvements allow for an all-weather crossing for Cathedral Canyon Drive and accommodate for projected growth. The project included relocation of multiple utilities and construction of a new sewer force main through the channel as well as a large drainage drop structure C. PROJECT TEAM ORGANIZATION

meant to control flow within the channel and avoid scour along the new bridge foundation. The new bridge carries four 12-foot lanes, a 10-foot raised median, an 8-foot outside shoulder/bike path, a 12-foot multipurpose trail and sidewalk, and a 5-foot sidewalk.

City of South Gate, I-710 Corridor Soundwall | South Gate, CA Project Manager supporting the Resident Engineer and the CM team for a $6.7M project which included constructing of a 292-foot-long retaining wall and an 874-foot-long soundwall in Caltrans right of way. The soundwalls foundations consisted of 16-inch to 24-inch cast-in-drilled-hole (CIDH) concrete pilings. In Caltrans right of way the construction consisted of Roadway excavation (Type Z-2 Aerially Deposited Lead), remove base and surfacing in front of the walls and placing asphalt, minor concrete v ditch behind the walls, curb and gutter, concrete barrier on top of the walls, Soundwall (masonry block), and landscape. On the City of South Gate right of way the construction consisted of removing 539 square feet of block wall in front of Thunderbird Villa Mobile homes, asphalt, curb and gutter, concrete sidewalk, decomposed granite meandering path, transparent noise barrier panels, cold mill asphalt, permeable pavers, landscape, installing 12-inch Ductile Iron Pipe waterline, and removing 8” Asbestos Cement Pipe waterline. The project was funded by Metro.

County of Riverside Transportation Department, Jurupa Road Grade Separation | Jurupa Valley, CA Project Manager and Resident Engineer for a railroad grade separation of the existing Union Pacific Railroad (UPRR) line at the crossing of Jurupa Road. The depression of Jurupa Road under the existing UPRR Mainline will result in lowering Felspar Street to the east of Jurupa Road. The project also involves the construction of a roadway bridge for Van Buren Boulevard, a railroad bridge for UPRR tracks, a temporary railroad shoofly, temporary shoring systems, retaining walls, storm drainage system, pump station, landscaping, roadway improvements, traffic signals, street lighting, and utility relocations along with associated removals and protection of existing facilities. A portion of the roadway along Jurupa Road will be waterproofed and dewatering is expected to be necessary for its construction as well as for the construction of the bridge. All work will be conducted and prepared in accordance with County and/or Caltrans practices, regulations, policies, procedures, manuals, and standards, as appropriate.

County of Riverside Transportation Department, I-10/Jefferson Street Interchange | Indio, CA Project Manager and Resident Engineer on the $44.1M Jefferson Street Interchange at I-10. The project includes constructing two parallel 440-foot-long by 78-foot-wide bridges, construction of all new eastbound and westbound on-/ off-ramps, auxiliary lanes on I-10, a 50-foot-tall mechanically stabilized earth (MSE) retaining wall, several Type 1 retaining walls, extensive traffic control, and public outreach. As Resident Engineer, Joseph provided guidance on all project elements starting from pre-bid services through project close-out and contract acceptance.

01/2023 - 07/2025

OBJECTIVE
The new bridge is 86 feet wide to accommodate four
lanes of traffic, six-foot-wide sidewalks, eight-foot-wide shoulders, and a 10- foot raised median. Project work
also included construction and removal of a bypass
road, CVWD water main and sewer relocations with
sewer bypass, storm drain lines, catch basins and dry
wells, channel slope paving, new AC roadway, sidewalks, driveways and curb and gutter and retaining walls. The
project also included demolition of two mobile homes
and one abandoned house and asbestos removal.

DESCRIPTION
TYLin provided construction management to the City of
La Quinta to replace the existing low water crossing with a 480-foot-long, 4-span, CIP, pre-stressed concrete box girder bridge. The bridge was constructed in two stages to keep Dune Palms Road open, with a closure pour later to connect the two bridges. The bridge improvements
provide easier access for motorists, pedestrians, and
cyclists, as Dune Palms Road is frequently used by high school students, mobile home park residents, and the skate park in the immediate area.

OUTCOME
Project was delayed due to damage sustained by Hurricane Hilary. CM and Contractor mitigated delay as best as possible by eliminating reconstruction of the bypass road and a subsequent traffic switch.

D. PROJECT EXPERIENCE
103

TYLin, a California Corporation, has been in business since 1954 and has experienced steady growth and financial stability throughout its history. The firm reported $832 million in revenue for 2024 and has strong banking relationships and the ability to access a line of credit, if required, to meet operating cash needs. TYLin has no planned office closures, mergers, or pending litigation that would affect delivery of this project for the City.

Elements that best demonstrate the firm’s financial responsibility are described below:
—Accounting System: TYLin utilizes Deltek Vision for a fully integrated General Ledger and Project Cost Accounting system. Deltek Vision is one of the industry-standard accounting softwares. TYLin has been using Vision for many years now, and our project managers and accounting staff are well versed in its use. —Compliance with GAAP and FAR: TYLin’s financial statements are kept in accordance with Generally Accepted Accounting Principles (GAAP). The accounting system allows costs to be accurately segregated by client and by contract and accumulated as per Federal Acquisition Regulations (FAR) requirements. —Independent CPA Audit: TYLin undergoes an independent Certified Public Accountant (CPA) audit annually. Deloitte is currently our independent auditor, and brings a high level of credibility to the audit. This process also includes annual verification of our indirect cost rate for purposes of government contracting. —Government Agency Audits: TYLin does an extensive amount of work with government agencies ranging from various federal departments to state DOTs and local agencies. Our government-audited overhead rate is typically the same as, or very close to, our stated overhead rate as determined by our independent CPA. This is indicative of the careful accounting practices and procedures that are in place to verify that the company is consistently following GAAP and FAR.
—Record Keeping: TYLin implements strict record keeping procedures to ensure that costs are verifiable. Timesheets are electronic and any changes are well documented. Receipts for all expenses are kept and included in the project files. timesheets and receipts are provided for invoices in accordance with requirements for cost-recoverable tasks.

E. Financial Capacity
TYLin | Golden Avenue Bridge Rehabilitation 13
E. FINANCIAL CAPACITY

Teaming Partnership
TYLin, in partnership with Biggs Cardosa, understands the City’s requirements for the Project. Replacing the Golden Avenue Bridge at Carbon Canyon Channel is a critical
investment for the City that requires disciplined oversight, proactive management, and seamless coordination to result in successful delivery. TYLin and Biggs Cardosa together provide the professional qualifications, licensure, technical resources, and proven track record necessary to manage
this federally funded project in full compliance with City, Caltrans, and FHWA requirements. Our understanding is
that this project is programmed under HBP, which utilizes federal funds and is therefore subject to all applicable federal requirements, including DBE participation and Buy America provisions, and will be overseen and audited by Caltrans for compliance. Backed by advanced technical
capabilities and modern management tools, our team
offers comprehensive construction management services
including contract administration, inspection, QA, and
stakeholder communication. Our objective is to act as
an extension of City staff by protecting public interests, minimizing risks, and delivering a project that meets the highest standards of safety, quality, and accountability.

This partnership is further strengthened by Biggs Cardosa’s unique role as the prime design engineer for the Golden Avenue Bridge Replacement Project and its active
involvement on the construction management team for
the adjacent OC Loop Segment D project, which directly
connects to the bridge. The Golden Avenue Bridge therefore plays a dual role: serving as essential infrastructure while also completing a critical link in the OC Loop trail system to improve regional connectivity, community access, and safety for pedestrians and cyclists.

TYLin is fully aware of the potential conflict of interest concerns that may arise when a design firm is also engaged in construction management services. In such cases, the actual conflict arises when the designer is responsible for evaluating and responding to construction claims,
particularly those related to errors or omissions in the bid documents. This can create a bias toward denying the
legitimacy of such claims, compromising the objectivity of the process.

To eliminate this potential conflict and ensure full
compliance with applicable City and federal procurement guidelines, TYLin has structured the team to maintain clear separation between design and construction oversight.

TYLin will serve as the prime Construction Management
consultant, with direct responsibility for Resident
Engineering services. This includes independently assessing contractor change orders and claims and acting as the City’s safeguard to verify fair and unbiased evaluations. TYLin has no commercial or contractual interest in the original design, and our sole focus is on delivering objective, high-quality construction management services.

Biggs Cardosa, the original designer, will be engaged
strictly in a technical support capacity, limited to field inspection services and QA. They will not be involved in any commercial decision-making, including the evaluation of claims, CCOs, or cost-related matters. All communication with Biggs Cardosa will be routed through TYLin’s Resident Engineer, ensuring a controlled and transparent flow of information that reinforces TYLin’s role as the independent authority in the field.

Importantly, having Biggs Cardosa on our team provides
a significant technical benefit. Their familiarity with the design allows for rapid responses to field issues, minimizing delays and ensuring continuity between design intent
and construction execution. Their proximity within our
team enables quick turnaround on technical clarifications, minimizing delays—without compromising the objectivity of construction oversight.

This organizational structure functions as a “firewall” between design and construction, preserving impartiality while leveraging technical expertise. It certifies that the City benefits from informed support without sacrificing transparency or accountability, and that the project is delivered on time, within budget, and to the highest
professional standards.

F. Project Understanding
and Approach
TYLin | Golden Avenue Bridge Rehabilitation 14
F. PROJECT UNDERSTANDING AND APPROACH
105

Technical Approach
Our understanding is that the Project will replace the
existing 26-foot-wide bridge over Carbon Canyon Channel with a new 60-foot-4-inch-wide structure designed
to improve safety, mobility, and connectivity. The new
bridge will provide two 12-foot travel lanes and 6-foot- wide sidewalks on both the south and north sides of
the structure. The superstructure will consist of PC/
PS CA I54 girders and will incorporate a Type 732SW
(Modified) barrier to meet current safety standards. It is also designed to accommodate six telecommunications
conduits, a 4-inch gas line, six conduits for Southern
California Edison (SCE), and a 16-inch casing for a future waterline. The substructure will be composed of abutments with a thickness of 3’-6”, supported on 2’-6” CIDH piles.

In addition, our understanding is that this project also completes the OC Loop Segment D from Station 21+00 to
29+00, which runs directly under the bridge, making it a critical link for regional trail connectivity.

A defining feature of the project is the incorporation of custom-designed precast decorative fascia panels, which we recognize as a construction critical and sensitive
elements of the bridge that could impact the construction schedule and quality if the fabrication and erection is mismanaged. These panels were developed specifically for this project and must be constructed and installed with absolute precision. Exact clearances must be maintained as detailed in the plans, as even minor deviations could create misalignment during installation or lead to long-term performance issues such as creep or displacement. Because of their unique design and structural integration, the fascia panels require comprehensive and disciplined QC, careful inspection, and proactive coordination with the contractor.

This feature represents a high-risk element where effective construction management will be essential to safeguard
the City’s investment, preserve the intended design, and avoid costly rework, construction delays and/or future
maintenance challenges.

Our understanding is that the bridge is located very close to property lines on the northeast and southwest quadrants, making it vital to implement vibratory monitoring, noise monitoring, and geotechnical stability monitoring to avoid potential damage to adjacent properties and protect the City from potential post-construction claims from these property owners. We also understand that an existing gas line on the northeast side will require coordination and relocation prior to bridge removal. At Abutment 1, conflicts exist with sheet piles RW2A on the northwest corner
and RW3A on the southwest corner, requiring careful
coordination and partial demolition to allow construction.

Because Biggs Cardosa participated as part of the
CM team on the OC Loop Segment D project, which
connects directly to this bridge, our team is familiar
with the existing conditions. This background helps us
anticipate key aspects of the partial sheet pile removal and associated construction activities, supporting an
efficient and well-coordinated project delivery while
minimizing risks and delays.

The overall project scope also includes demolition of the existing bridge, excavation and earthwork, new drainage and storm drain facilities, slope stabilization, utility relocations, concrete flatwork, paving, traffic control, and safety enhancements. Construction is expected to
be completed within 120 working days from NTP, with
liquidated damages of $4,200 per working day for delays.

TYLin | Golden Avenue Bridge Rehabilitation 15
F. PROJECT UNDERSTANDING AND APPROACH
106

Our understanding is that, as a federally funded project, it will require strict compliance with Caltrans standards, LAPM, prevailing wage requirements, and DIR monitoring.

If selected, our team will provide the full range of CM and inspection services including pre-construction coordination, contractor schedule review and monitoring, field
measurements of quantities, pay request review, inspection and QA, labor compliance, traffic control review, jobsite safety oversight, and facilitation of communication with City staff. Our understanding is that laboratory and/or testing services will also be required for project materials, which will be performed by our certified subconsultant S2 as part of our comprehensive quality assurance program.

PRIMARY PROJECT CONCERNS AND ADVANCED

TECHNIQUES
We are committed to assisting the City in meeting its overall objectives in this construction contract. In our review of the plans and specifications, our team foresees challenges that will require focused pre-planning and attention to avoid significant delay and ensure the success and timely completion of the project. Some are listed below and on the following page for your consideration:

Key Issue Challenges Mitigations and Opportunities
Excavation and
Vibration Monitoring
Residences located on the northeast and
southwest quadrants are very close to
the project site, creating a risk of noise
disturbance, vibration impacts, and
potential soil instability during excavation
and construction.

Implement noise, vibration, and soil stability
monitoring with real-time alerts to protect
nearby residences and reduce risk of damage
or claims. Meet with owners to address
their concerns.

TYLin | Golden Avenue Bridge Rehabilitation 16
F. PROJECT UNDERSTANDING AND APPROACH
107

Key Issue Challenges Mitigations and Opportunities
Detour Plan
Detour routes require approval from the
City of Yorba Linda, which may impact
schedule if not coordinated early.

Coordinate all traffic control plans with
Yorba Linda in advance, maintain clear
communication, and use this as an opportunity
to strengthen interagency collaboration.

PC/PS Girders
I-Girders are harder to get and more
expensive than Wide Flange (WF) girders;
the design is tied to decisions and details
established with the Type Selection over
10 years ago.

The contractor may propose a Value
Engineering Change Proposal to change to WF
girders and lower costs. However, the design
and architectural facia details would need
careful review to assure constructability and
actual cost savings.

Conflicts at Abutment
1 with Sheet Piles
RW2A (NW corner) +
RW3A (SW corner)
Existing sheet piles interfere with
the construction of Abutment 1,
requiring partial demolition and careful
coordination to avoid delays and
structural complications.

Leverage Biggs Cardosa’s firsthand experience
from the OC Loop Segment D project to manage
partial sheet pile removal at RW2A and RW3A
efficiently, coordinating closely with OCPW
and the contractor to minimize risks and
maintain progress.

Bike Path Keeping the Bike Path open during
construction.

Implement a comprehensive safety and traffic
control plan, including wayfinding maps for
alternate routes, advance notifications and
alerts, flaggers at either end of the bridge to
manage bike traffic and limiting path closures
strictly to unsafe operations (Girder Erection,
Deck pour, etc,). These measures ensured
that the bike path construction progressed
efficiently while prioritizing the safety of both
cyclists and construction personnel.

Bridge Demolition
and Channel Fence
Protection
The bridge must be removed without
damaging the channel fence, and the
channel must remain protected during
demolition, requiring coordination with
USACE and LACFCD.

Require the contractor to include cover and
protection measures for the channel and the
fence in their demolition submittal. Carefully
review and enforce the approved measures.

CIDH Pile Installation
Groundwater may be present during
drilling, which could require dewatering to
properly install the piles.

Plan for possible “wet-pile” installation, and use
best practices to ensure pile integrity and avoid
delays. Early approval will prevent delay if wet
conditions are not anticipated.

Deck and PC/PS Girder
Source Inspection
The deck will be poured on site, but
girders must be inspected at the precast
plant; quality concerns if contractor’s QC
is inadequate.

S2 will perform source inspection on an
optional basis for the PC/PS girders. CM will
check the contractor QC plan including current
precast plant inspections and certification, and
verify girders are delivered with Certificates
of Compliance.

Fascia Panel
Connection
The precast decorative fascia is custom
designed for this bridge and must be
installed with precise clearances. Any
misalignment could constructability
issues and/or create long-term
maintenance issues such as creep
or displacement.

Closely monitor installation, verify connections
match design tolerances, and coordinate
with the contractor to ensure the fascia
is constructed and installed correctly the
first time.

G. Scope of Work
TYLin and Biggs Cardosa establishes the strength of our services on extensive experience with bridge projects
and federally funded programs. Our commitment is to
respond promptly and effectively to the City’s construction management needs, ensuring that every member of our
team delivers the highest level of service and consistently meets the City’s expectations.

Construction Administration
CONSTRUCTION MEETINGS, SCHEDULE, + FIELD MEETINGS
Mazen Mneimneh, our Resident Engineer and Structures
Representative, will coordinate weekly meetings with the contractor, the City, the designer (as needed), and third- party representatives to review project progress, identify and resolve issues, and address upcoming construction
activities, schedule, safety, and coordination with outside agencies. Mazen will also schedule, lead, and facilitate pre-construction meetings, regular progress meetings,
and other on-site construction-related discussions.

Key discussions, decisions, and action items will be
thoroughly documented through meeting minutes, which
will be prepared, distributed, and maintained in the
project records.

SCHEDULE REVIEW
The TYLin CM Team bring extensive knowledge of
construction methods and strong expertise in the
use of industry-standard scheduling software such as
Primavera P6 and Microsoft Project. This ensures that
project schedules are developed accurately, maintained
properly, and used effectively to plan, monitor, and control construction activities. Avraham Frank will assist Mazen in reviewing the contractor’s baseline schedule as well as all subsequent schedule updates to verify reasonableness, accuracy, and compliance with project requirements.

SUBMITTAL MANAGEMENT
The CM team will manage the review of project submittals, providing approvals or recommendations for approval in a timely and efficient manner. A comprehensive submittal log will be established at the outset of the project, continuously maintained, and updated to track the status of all items while clearly identifying the parties responsible for review and acceptance. To ensure accountability and effective
coordination, the submittal log will be a standing agenda item during weekly progress meetings, allowing for prompt discussion and resolution of outstanding issues.

REQUESTS FOR INFORMATION
The CM Team will process, track, and document all project RFIs and responses. An RFI log will be established at the beginning of the project and continuously maintained and updated to capture the status of each item and clearly
identify the parties responsible for review and response.

The Resident Engineer will prepare timely responses to RFIs in full compliance with contract requirements, ensuring that the City’s Project Manager is copied on all correspondence to keep the City fully informed throughout the process.

CONTRACT CHANGE ORDERS
The Resident Engineer will carefully review all necessary changes to the project and promptly advise the City
regarding their potential impacts on the project schedule and budget. Our team is committed to ensuring that all
CCOs are processed in a transparent, accurate, and timely manner with clear documentation to support City decision- making. Please see the level of effort assumed for managing CCOs. To achieve this, we will:
f Assemble complete documentation of item quantities,
cost calculations, inspection reports, test reports, drawings, photographs, and other supporting materials as required. f Obtain concurrence from the designer for any CCOs that modify the design.
f Prepare detailed CCO estimates, including Force Account Analyses and evaluations of potential time impacts to the contractor’s schedule and operations. f Evaluate contractor price proposals for reasonableness, accuracy, and consistency with contract requirements. f Negotiate CCOs with the contractor as directed by
the City.
f Prepare formal CCO packages and attachments upon approval from the City, designer, and other stakeholders as appropriate. f Maintain and update a comprehensive CCO log to
track proposed changes through review, transmittal,
and approval.

Through this structured approach we will provide the City with the confidence that all changes are fully vetted, fairly negotiated, and carefully documented, helping to control costs, maintain the schedule, and avoid potential claims.

PROGRESS PAYMENT
The CM Team will prepare accurate calculations for all
completed work and the Resident Engineer will review and accept work items to support progress payments. Field
measurements will be performed as necessary to verify
quantities and prevent overpayment or underpayment.

All progress payment estimates will be fully traceable
to verified source documents based on field-measured
or calculated quantities. Once payment verification is
complete, the Resident Engineer will submit a monthly

progress payment certification to the City for review,
approval, and processing. Progress payment reports will clearly separate eligible and ineligible costs to ensure proper reimbursement under the HBP.

CONTRACT CONFORMANCE
TYLin will lead the construction observation effort by
performing the Resident Engineer role, while Biggs Cardosa will provide QA inspection to verify that all construction activities are performed in strict compliance with the
contract documents. This partnership ensures that the City receives both strong project oversight and independent
QA review. Our goal is to operate as a cohesive team,
supporting the Contractor in resolving issues promptly, maintaining compliance, and preventing potential problems or delays during construction.

Construction Observation/
Inspection Services

PRECONSTRUCTION CONDITION SURVEY
The preconstruction survey will be guided by the CM
Team and will include a detailed photo documentation
log capturing the existing conditions of the project site and adjacent residences. The CM Team will provide QA
reviews to ensure that the documentation is accurate,
complete, and reliable. The resulting record will be
maintained as part of the project files and furnished to the City, serving as a critical reference to protect the City against potential tort claims by providing clear evidence of preconstruction conditions.

QUALITY ASSURANCE INSPECTIONS/MATERIALS TESTING
The Contractor will be responsible for implementing its own QC program. TYLin, with support from Biggs Cardosa, will provide QA oversight to ensure that the contractor’s QC plan is properly executed and that results are independently verified. Biggs Cardosa inspectors will perform daily QA inspections and conduct materials sampling and testing
to confirm that all work complies with the approved plans and specifications. Our QA approach is focused on ensuring that the contractor’s methods and procedures result in
full compliance with the contract requirements while
providing the City with an additional layer of oversight and accountability.

DAILY INSPECTION REPORTS
The Resident Engineer will review the Daily Inspection
Reports prepared by Biggs Cardosa inspectors as part of their QA duties to ensure they are accurate, complete, and fully compliant with project requirements. These reports will be prepared using a proven template that has been
successfully applied on previous projects and accepted
under Caltrans audits. Each report will document daily
construction activities, weather conditions, labor and
equipment, materials incorporated, safety observations, and any issues affecting progress. This comprehensive
documentation will provide a reliable project record,
support verification of quantities, and serve as the basis for progress payment calculations. It will also give the City clear, consistent, and audit-ready reporting that strengthens accountability and protects against potential disputes.

PHOTOGRAPHS & VIDEOTAPE
Photos and videos will be taken on a daily basis, clearly labeled, and properly filed. Documentation will occur
before the start of construction to record existing site conditions, during construction to capture daily progress, and after construction to verify project completion. These records will also serve as an additional resource to verify the contractor’s work, labor, and related activities, providing the City with a clear and reliable visual record throughout the project.

Document Control/Labor Compliance

DOCUMENT TRACKING SYSTEM
Our Office Engineer, Abigail Manriquez, will implement
and maintain a Caltrans-based document control system,
customized and modified for the City, to manage all project records. This system will be modeled on the Caltrans 63- file structure, which is the industry standard for federally funded projects, and will be tailored to the City’s specific needs. Our team will work closely with the City’s Project Manager to establish the document control framework
at the start of the project and ensure it is maintained throughout construction.

As part of our customized CM approach, the CM Team will organize and manage project document control, storage,
and retrieval methods in full compliance with Federal, State, and City procedures. Project records will include, but will not be limited to, Weekly Statement of Working Days, Daily Inspection Reports, Correspondence, Submittals, CCOs,
Notices of Potential Claim (NOPC), Progress Payments,
Lab and Field Test Reports, Materials Delivery Tickets and Compliance Certifications, Progress Reports, Progress
Photos, Meeting Minutes, and Monthly Reports. This effort will be led by the Resident Engineer with support from the CM team to ensure all documentation is complete, accurate, and audit ready.

CONTRACT LABOR COMPLIANCE
The CM Team will ensure full compliance with the Davis- Bacon Act by conducting employee interviews with
the Contractor’s laborers to verify labor compliance
requirements. Our team will review the Contractor’s
certified payrolls, daily inspection diaries, and prevailing wage records to confirm that Equal Employment
Opportunity (EEO) requirements are implemented and
properly documented in the project files. Additionally, based on Addendum #2 issued on October 7, 2025, we
are not required to monitor or verify the contractor’s
compliance with DBE participation goals or the minimum
trainee requirements outlined in LAPM Chapter 12.8.

However, we remain prepared to support this effort should the DBE requirements change. These efforts will ensure
that both federal and state labor compliance objectives are TYLin | Golden Avenue Bridge Rehabilitation 19

fully met while protecting the City’s eligibility for federal funding and supporting workforce development and equal
opportunity throughout the project.

WEEKLY STATEMENT OF WORKING DAYS
As the daily field inspector, Biggs Cardosa will monitor the Contractor’s work on a daily basis and prepare detailed daily reports documenting all work items, quantities,
directives, work locations, dates and times, weather
conditions, and other pertinent information. TYLin, serving as Resident Engineer, will review these reports for accuracy and completeness and use them to prepare the Weekly
Statement of Working Days. This statement will track total contract time from the first to the last chargeable day, including weather days, holidays, approved CCO days, and controlling activities for each week. The Weekly Statement of Working Days will be compared against the Contractor’s CPM Schedule to evaluate progress and performance.

Once finalized, the statement will be signed by the
Resident Engineer and transmitted to the Prime Contractor each week.

Environmental Compliance
The CM Team will ensure that construction activities are carried out in full compliance with project permits and specifications. We will oversee the contractor-supplied biologist throughout construction and review their
qualifications prior to the start of work to confirm that they meet the criteria outlined in the Project Manual. We will also review the pre-construction survey report prepared by the contractor-supplied biologist to verify that all required tasks have been completed, results are comprehensive, and any additional required or recommended actions are addressed.

Similarly, we will review the post-construction survey report to confirm that requirements have been satisfied, results are complete, and any follow-up actions are included. If required, we will also prepare the Post-Construction Close- out Report for submission to CDFW.

TRIBAL CULTURAL RESOURCES (NATIVE AMERICAN

COORDINATION PER CEQA REQUIREMENTS)
As part of the TYLin Team, Robin Turner with APRM will be responsible for the coordination with construction crews to document the date, location, and results of monitoring activities ensuring regulatory compliance during excavation and grading activities. APRM will work in the facilitation and coordination with the Tribes to ensure compliance with their TR-1 mitigation measures, uphold all required Caltrans and City cultural resources mitigation, and comply with the paleontological mitigation measures whether implied in the RFP or to cover the gaps that were inadvertently excluded in the RFP. APRM is very familiar working with the tribes and understanding their concerns.

Post Construction Activities

PRE-FINAL/FINAL INSPECTION
The CM Team will provide continuous inspection of the work throughout construction and will prepare a punch list at the end of the project identifying all deficiencies that require correction. Our staff will monitor the work until every item on the punch list has been addressed. Once all items have been completed, a final inspection will be performed to confirm compliance before the project is accepted.

PROJECT CLOSE OUT & TRANSFER OF PROJECT RECORDS
The CM Team will follow the City’s guidelines for project close-out documentation and project acceptance. At the
conclusion of the project, all files and As-Builts will be organized, packaged, and delivered to the city. Close-out documentation will include submittals, RFIs, CCOs, and
associated logs with conformance review letters; daily
inspection reports; photo and video documentation;
quarterly progress reports; approved as-built record
drawings; special inspection reports and logs detailing dates, descriptions, locations, quantities, and test results for all inspections and material tests; shop drawings with field notes filed by specification; the completed punch list; and a final project acceptance report with written assurance that the work has been completed in full compliance and is ready for acceptance by the City.

PROPOSED CONSTRUCTION SCHEDULE
In response to Section H of the RFP, our proposed schedule is presented on the following page. This simplified schedule outlines the anticipated construction activities along with the corresponding CM tasks for each activity. It is based on a more detailed CPM schedule already developed by TYLin.

Key assumptions include a mobilization date of January
2026 and a construction duration of 120 working days
(approximately six months). We have also incorporated
key pre-construction activities that must occur prior to mobilization to ensure the project remains on track and free of delays.

TYLin will review the contractor’s initial CPM schedule and work collaboratively to identify opportunities for schedule optimization. Potential delays will be flagged early through monthly schedule updates. Our team will conduct detailed reviews focused on maintaining schedule commitments,
monitoring critical and near-critical path activities, and identifying opportunities to recover or accelerate the
schedule. This proactive approach helps streamline CM
efforts while maximizing overall project efficiency.

• The term “Agreement” also means “Contract.”
• LPA also means the local entity entering into this contract with the Contractor or Consultant. • The term “Small Business” or “SB” is as defined in 49 CFR 26.65.

2. AUTHORITY AND RESPONSIBILITY

The Consultant must ensure that DBEs and other small businesses have the opportunity to participate in the performance of the work that is the subject of this solicitation and should take all necessary and reasonable steps for this assurance. The proposer must not discriminate on the basis of race, color, national origin, or sex in the award and performance of subcontracts.

B. Proposers are encouraged to use services offered by financial institutions owned and controlled by DBEs.

3. SUBMISSION OF DBE INFORMATION
If there is a DBE goal on the contract, Exhibit 10-O1: Consultant Proposal DBE Commitment must be included in the Proposal. In order for a proposer to be considered responsible and responsive, the proposer must make good faith efforts to meet the goal established for the contract. If the goal is not met, the proposer must document adequate good faith efforts. All DBE participation will be counted towards meeting the contract goal; therefore, all DBE participation must be collected and reported.

Exhibit 10-O2: Consultant Contract DBE Information must be included in best qualified consultant’s executed consultant contract. Even if no DBE participation will be reported, the successful proposer must execute and return the form.

4. DBE PARTICIPATION GENERAL INFORMATION

B. If the materials or supplies purchased from a DBE regular dealer, count 60 percent of the cost of the materials or supplies. A DBE regular dealer is a firm that owns, operates or maintains a store, warehouse, or other establishment in which the materials, supplies, articles or equipment of the general character described by the specifications and required under the Contract are bought, kept in stock, and regularly sold or leased to the public in the usual course of business. To be a DBE regular dealer, the firm must be an established, regular business that engages, as its principal business and under its own name, in the purchase and sale or lease of the products in question. A person may be a DBE regular dealer in such bulk items as petroleum products, steel, cement, gravel, stone or asphalt without owning, operating or maintaining a place of business provided in this section.

C. If the person both owns and operates distribution equipment for the products, any supplementing of regular dealers’ own distribution equipment must be, by a long-term lease agreement and not an ad hoc or Agreement-by-Agreement basis. Packagers, brokers, manufacturers’ representatives, or other persons who arrange or expedite transactions are not DBE regular dealers within the meaning of this section.

D. Materials or supplies purchased from a DBE, which is neither a manufacturer nor a regular dealer, will be limited to the entire amount of fees or commissions charged for assistance in the procurement of the materials and supplies, or fees or transportation charges for the delivery of materials or supplies required on the job site, provided the fees are reasonable and not excessive as compared with fees charged for similar services

EXHIBIT B

INSURANCE REQUIREMENTS

A. Minimum Scope and Limits of Insurance

City reserves the right to review any and all of the required insurance policies and/or endorsements, but has no obligation to do so. Failure to demand evidence of full compliance with the insurance requirements set forth in this Agreement or failure to identify any insurance deficiency shall not relieve Consultant from, nor be construed or deemed a waiver of, its obligation to maintain the required insurance at all times during the performance, including any extension thereof, of this Agreement.

Consultant shall obtain, maintain, and keep in full force and effect during the life of this Agreement, including any extension thereof, all of the following minimum scope of insurance coverages:

1. Commercial General Liability Insurance

Broad-form commercial general liability, with coverage at least as broad as the most current version of ISO Commercial General Liability coverage form CG 00 01, in a form at least as broad as ISO form CG 00 01 04 13, and shall include insurance for premises and operations, products/completed operations, broad form property damage, blanket contractual liability, independent contractors, personal injury or bodily injury, and personal and advertising injury with a policy limit of not less than Two Million Dollars ($2,000,000.00) per occurrence and Four Million Dollars ($4,000,000.00) general aggregate. The aggregate limit, encompassing the above coverage, shall apply separately to this project/location. If Consultant maintains higher limits than the specified minimum limits, City requires and shall be entitled to coverage for the higher limits maintained by the Consultant.

2. Business Automobile Liability Insurance

Business automobile liability for all owned, hired, leased, and non-owned vehicles at least as broad as the most current version of ISO Business Auto Coverage form CA 00 01, with a policy limit of not less than Two Million Dollars ($2,000,000.00) combined single limit per accident. If Consultant maintains higher limits than the specified minimum limits, City requires and shall be entitled to coverage for the higher limits maintained by the Consultant.

3. Workers’ Compensation and Employer’s Liability Insurance

Workers’ compensation insurance as required by the State of California and Employer’s Liability Insurance with a minimum limit of One Million Dollars ($1,000,000.00) per accident for any employee or employees of Consultant. Consultant agrees to waive and to obtain endorsements from its workers’ compensation insurer waiving subrogation rights under its workers’ compensation insurance policy against the City, its officers, officials, agents, employees, and volunteers for losses arising from work performed by Consultant for the City and to require each of its subcontractors, if any, to do likewise under their workers’ compensation insurance policies.

By signing this Agreement, the Consultant acknowledges and agrees to the following:
136

I am aware of the provisions of Section 3700 of the Labor Code which require every employer to be insured against liability for Workers' Compensation or to undertake self-insurance in accordance with the provisions of that code, and I will comply with such provisions before commencing the performance of the work of this contract.

The Consultant shall also comply with Section 3800 of the Labor Code by securing, paying for, and maintaining in full force and effect for the duration of this Agreement, complete workers’ compensation insurance, and shall furnish a certificate of insurance to the Project Manager before execution of this Agreement by the City. The City, its officers, officials, agents, employees, and volunteers shall not be responsible for any claims in law or equity occasioned by failure of the Consultant to comply with this Section.

4. Professional Errors and Omissions (“E&O”) Liability Insurance

Professional errors and omissions (“E&O”) liability insurance appropriate to the Consultant’s profession, with limits of not less than Two Million Dollars ($2,000,000.00) per occurrence and Three Million Dollars ($3,000,000.00) aggregate. The retroactive date must be shown and must be before the date of the contract or the beginning of contract work. Insurance must be maintained and evidence of insurance must be provided for at least five (5) years after completion of the contract of work. If coverage is canceled or non-renewed, and not replaced with another claims-made policy form with a retroactive date prior to the contract effective date, the Consultant must purchase “extended reporting coverage” for a minimum of five (5) years after completion of contract work. A copy of the claims reporting requirements must be submitted to the Project Manager for review. If Consultant maintains higher limits than the specified minimum limits, City requires and shall be entitled to coverage for the higher limits maintained by the Consultant.

5. Standards for Insurance Companies

All insurance policies shall be issued by an insurance company currently authorized by the Insurance Commission to transact business of insurance or is on the List of Approved Surplus Line Insurers in the State of California, with an assigned policyholders’ rating of A- (or higher) and Financial Size Category Class VII (or larger) in accordance with the latest edition of Best’s Key Rating Guide.

B. Documentation and Other Provisions

1. The commercial general liability insurance policy and business automobile liability policy shall be endorsed to contain the following: The City of Placentia, its officers, officials, agents, employees, and volunteers are additional insureds with respect to: liability arising out of activities performed by or on behalf of the Consultant pursuant to its contract with the City; products and completed operations of the Consultant; premises owned, occupied, or used by the Consultant; and automobiles owned, leased, hired, or borrowed by the Consultant. General liability coverage can be provided in the form of an endorsement to the Contractor’s insurance at least as broad as one of the following ISO ongoing operations forms: CG 20 10 or CG 20 26 or CG 20 33 (not allowed from subcontractors), or CG 20 38; and one of the following ISO completed operations forms:

CG 20 37, 2039 (not allowed from subcontractors), or CG 20 40.

2. Said policies shall not terminate, nor shall they be cancelled or coverage reduced, without 137

at least thirty (30) days’ written notice to the City. In the event of any cancellation or reduction in coverage or limits of any insurance, Consultant shall forthwith obtain and submit proof of substitute insurance. Should Consultant fail to immediately procure other insurance, as specified, to substitute for any cancelled policy or reduction in the required coverage limits, the City may procure such insurance at Consultant’s sole cost and expense.

3. The Consultant’s insurance coverage shall be primary insurance coverage at least as broad as ISO CG 20 01 04 13 as respects the City of Placentia, its officers, officials, agents, employees, and volunteers. Any other insurance maintained by the City of Placentia shall be excess and not contributing with the insurance provided by this policy.

4. Any failure to comply with the reporting provisions of the policies shall not affect coverage provided to the City of Placentia, its officers, officials, agents, employees, and volunteers.

5. Defense fees and costs shall not deplete the limits of any insurance provided under this Agreement.

6. The Consultant’s insurance shall apply separately to each insured against whom claim is made or suit is brought, except with respect to the limits of the insurer’s liability.

7. Consultant shall require and verify that all subcontractors maintain insurance meeting all the requirements stated herein, and Consultant shall ensure the City is an additional insured on insurance required from subcontractors.

8. Consultant agrees to waive, and to obtain endorsements from insurers waiving, subrogation rights against the City, its officers, officials, agents, employees, and volunteers for losses arising from work performed by Consultant for the City and to require each of its subcontractors, if any, to do likewise under their insurance policies.

9. Coverage shall be on a standard occurrence form. Claims-made forms are not acceptable, except under the Professional Errors & Omissions (“E&O”) Liability policy.

Modified, limited, or restricted occurrence forms are not acceptable.

Subject: Extra Services and Fee Request – Construction Bidding Services and Construction Phase Services for Golden Avenue Bridge Replacement Project at Carbon Canyon Channel Federal Project No. BRL-5269(025) Bridge NO. 55C-0192
Dear Chris:

Biggs Cardosa Associates is submitting this Extra Services and Fee Request as requested for engineering support during the Construction Bidding and Construction Phases of the Golden Ave. Bridge Replacement Project. The scope provided in this proposal is intended to carry the project to completion with an assumed maximum construction duration of 8 months. The Tasks are broken down and described as follows:

Construction Bidding Services
The BCA design team will aid the City during the bidding process. This assistance includes attending one Pre- Bid Construction Meeting and one additional office/ field meeting to clarify any design questions raised and found from a review of the plans prior to the beginning of construction on the project. The BCA team will work closely with City staff to respond to all bid inquiries and questions relating to the plans and specifications during the bid period. Should addenda be required, the BCA team will assist with their preparation. All written responses to Contractor inquiries will be provided within two (2) working days of receipt of the Contractor’s request. Along with this support, we will also be available to attend the bid opening. If requested, the BCA team will conduct a review of Contractor services identified within the bids and supporting documentation to assist in confirmation of the lowest responsive and responsible bidder. Once this review is complete, we will make a recommendation to the City for acceptance and award, or if a rebid of the project is determined to be necessary.

Construction Phase Services
BCA will assist the City during construction which is anticipated to last between 6 to 8 months. The following tasks assume a duration of 8 months and include responding to requests for information (RFI’s), assisting in contract change orders (CO’s), reviewing shop drawings and materials/product submittals for conformance with the plans and specifications, provide clarification of design intent, when necessary, field visits to address construction issues and to observe construction of key structural components. It is assumed that there will be monthly meetings to discuss the progress of the project’s construction (8 total) and also a total of 8 field visits is assumed for the preparation of this fee estimate. Within thirty (30) days following the completion and acceptance of the Project and receipt of the field redlined planset, the BCA team will furnish a complete set of As-BuiIts in PDF format to the City. Revisions will be clouded and solely based upon as-built information provided to the City and the BCA team by the City’s Construction Manager and the Project Contractor. Upon approval of the As-Built plans by the City, if requested we will plot the As-Builts on Mylar for submittal to the City for their records.

As previously stated, should the OC Loop Project require changes in our project’s design, the changes would be addressed during the construction stage. Accordingly, we have assumed a nominal amount of Exhibit A
151

time that may be required for a redesign and the drafting and coordination related to any changes. Given the unknown nature of any future changes in design, this work effort and the accompanying budget should be viewed as provisional and subject to future amendments should the scope of the changes exceed the resources allotted in this proposal.

Permitting Services
If construction is not contracted to start by March 14, 2026 and/or will not be completed by March 14, 2027, a Nationwide Permit Reverification will be required from the United States Army Corps of Engineers (USACE).

As part of the 404 Nationwide Permit Reverification, the USACE will require resubmittal of the Section 401 Water Quality Certification to the Regional Water Quality Control Board. This proposal includes an optional scope and budget to account for a 401 Water Quality Certification application and a 404 Pre-Construction Notification package, should the need arise. For more detailed scope information, please see the attached Scope of Work.

Similarly, the project’s 408 permit is set to expire in April 2026 and if construction is not finished by then an extension will be required. BCA anticipates a pro-forma extension, with minimal effort required, and no production of new design materials. We have allotted hours accordingly, in the attached fee estimate sheet.

Environmental Services
Environmental Commitments Record (ECR): It is anticipated that the environmental document will include environmental commitments that must be conducted prior to, during, and following construction.

GPA will prepare, update, and maintain the ECR and will document completion of all environmental commitments throughout the pre-construction and construction monitoring phases. GPA will update and maintain electronic and hard copies of the ECR and all documentation associated with environmental compliance.

Monitoring of ESA Fence Installation: We will monitor installation of Environmentally Sensitive Area fencing around the protected root zone of the southern California walnut trees to be protected in place.

GPA will include photos from the monitoring visit in a construction monitoring log for the project files.

Pre-Construction Surveys:

General Wildlife Survey - GPA will conduct general pre-construction surveys no more than 48 hours prior to construction to determine presence/absence of special-status wildlife within the project area. Additional surveys would be required if work is delayed for five days or more. The general wildlife survey will be conducted by one biologist and one trip to the site and assumes construction will not be delayed for five days or more after the survey is conducted.

Nesting Bird Survey - If trimming or removal of vegetation is conducted during the nesting bird season (February 1 to September 15), GPA will conduct nesting bird surveys no more than 48 hours prior to trimming or clearing activities within 500 feet of the construction area. Additional surveys would be required if trimming or removal activities are suspended for five days or more. The nesting bird survey will be conducted by one biologist and one trip to the site and assumes trimming/removal activities will not be delayed for five days or more after the survey is conducted.

Paleontological Mitigation Plan (PMP) / Native American Coordination / Pre-Grade Meeting and Resource Awareness Training: Please see the attached GPA scope, Tasks 6-8 for detailed scope information.

Agency Notifications
We will coordinate with the City to complete any required post-construction submittals and notifications.

Notifications include those required by regulatory permits to document and summarize the results of project construction and post-construction conditions. We will coordinate with the City to gather and/or prepare the necessary documentation and will submit the information to the agencies, as required. 152

Construction Monitoring
As stated in MM CUL-2 and CUL-4, archaeological monitoring will be full-time during all ground disturbing activities, and paleontological monitoring will begin when excavation reaches a depth of eight feet. GPA subconsultant DUKE CRM will provide one cross-trained archaeological/ paleontological monitor during all ground disturbing activities with the potential to impact archaeological resources. The monitor will follow construction equipment observing the freshly excavated soils. Monitoring will occur at the pace of construction.

For more detailed scope information, please see the attached GPA scope.

Compliance Report - Following the completion of paleontological/archaeological monitoring and assuming negative findings, DUKE CRM will prepare a short compliance letter report that meets Caltrans requirement for a PMR. The report will document the type of monitoring activities conducted, report any problems or issues that occurred, and state clearly that no resources were identified. It will include photographs and soils/stratigraphic discussions. The report will be submitted to the City. If significant artifacts are discovered, a more detailed report will need to be prepared; this cost is not included in this proposal. At the City’s request, a separate scope and fee proposal can be submitted for approval in the event that significant artifacts are discovered.

Fee
Our construction support services fee represents our best estimate of the costs involved. The construction support services costs are highly unpredictable, and highly dependent on the contractor's proficiency / performance and the overall construction schedule. The final cost may be above or below the amount estimated in this proposal. For the reasons listed above, we recommend that the City establish a contingency budget for construction support services. This budget can then be utilized if more effort is required.

BCA proposes to provide the various ‘Services’ outlined in this proposal, including direct expenses but not including the optional services described above, for a fixed base fee not to exceed $168,797. The optional services can be provided for a fixed base fee not to exceed $13,532 upon written approval by the City. A detailed breakdown of our fee proposal is attached. Please note that BCA’s previously used rates have expired.

Updated rates are used for this Extra Services request.

Assumptions made in the preparation of this proposal:
▪ All work described in this scope applies to the Golden Avenue Bridge Replacement Project only. It is assumed that any construction support work (including Environmental Services) required for the portion of the OC Loop project that will be constructed concurrently will be performed by others, in consultation with the Engineer of Record for the OC Loop project.
▪ This scope includes review of all structural shop drawings and structural submittals required by the project specifications and the Caltrans Standard Specifications including but not limited to precast girder shop drawings, bridge removal plan, pile placement plan, tubular handrail shop drawings, and precast decorative fascia shop drawings. This scope does not include review of the submittals listed in the Caltrans OSFP Information and Procedures Guide Section 5-4 that are typically reviewed and approved a t the field level (rebar shop drawings, standard falsework system shop drawings, concrete mix designs, etc). We have assumed that these field level submittals will be reviewed by the RE.
▪ It is assumed that the RE will be the lead reviewer for all roadway/civil related submittals/shop drawings , and that the design team will provide information as needed in a supporting role for up to five (5) roadway/civil related submittals/shop drawings.
153

▪ A maximum of two (2) rounds of reviews (i.e. one resubmittal) are assumed for each set of structural shop drawing submittal. The revisions required for the resubmittals are assumed to be minor and will not require another complete shop drawing review.
▪ Responding to RFIs and developing associated CCOs to address contractor errors, alternative construction method requests, or unforeseeable construction field issues (contractor scheduling, contractor equipment limitations, 3rd party coordination/limitations, undocumented existing conditions, etc.) is not included in the scope of services but can be added as Extra Work Requests as required.
▪ The USACE 408 permit extension will require only a pro -forma extension request and wi ll not require preparation and submittal of any new design materials.
▪ OC Loop reviews have been completed. If any reviews or field visits are requested, they will be considered out of scope and not included in this proposal . Requested design changes that require resources in excess of those allotted in this this proposal will be considered out of scope. ▪ Construction is anticipated to last approximately six to eight months. If the construction schedule changes and additional services and/or monitoring are requested, an additional scope of work and budget to support this effort can be provided upon request.
▪ Site visits are limited to structural observations only during construction. Special structural inspections are not part of this scope and fee proposal. If requested, BCA can provide a separate scope and fee proposal for Inspection Services.
▪ Remedial engineering design to determine corrective action required due to materials and/or contractor's operations not meeting contract requirements is not included in this proposal. If requested, BCA can provide this work as extra services.
▪ Engineering advice and technical support for construction change orders to the plans and specifications initiated by the contractor, preparation of change order documentation which would include, where appropriate, changes to plans and specifications, and additional structural details are not included in this proposal. If requested, BCA can provide additional hours to perform these duties, as additional services. ▪ We shall review or take other appropriate action upon Contractor’s submittals, as requested by the City or the CM’s RE, such as Shop Drawings, Product Data and Samples, but only for the limited purpose of checking for conformance with information given and the design concept expressed in the Contract Documents. Review of such submittals is not conducted for the purpose of determining the accuracy and completeness of other details such as dimensions and quantities or for substantiating instructions for inst allation or performance of equipment or systems designed by the Contractor, all of which remain the responsibility of the Contractor to the extent required by the Contract Documents.
▪ All shoring design will be the responsibility of the contractor and their designated licensed Civil Engineer. Biggs Cardosa Associates will conduct a limited and cursory review of all shoring submittals to check for general compliance with the design concept of the project and general compliance with the information given in the contract documents.
▪ The 404 Nationwide Permit is valid until March 14, 2026. If construction has initiated or is under contract to initiate by that date, the City has an additional 12 months to complete the project. It is assumed construction will be completed by March 14, 2027.
▪ If construction is initiated by March 14, 2026 and completed by March 14, 2027, further coordination with the Regional Water Quality Control Board regarding the Water Quality Certification is not required. ▪ Per the California Department of Fish and Wildlife, a 1602 notification is not required for the project unless the 154

project changes materially from what was submitted to CDFW in 2019. Therefore, updates to the 1602 permit are not required. If requested, this would be provided under a separate scope and cost. ▪ Because the regulatory agencies update their fees annually, it is assumed that the City will be responsible for direct payment of all regulatory permitting fees associated with the project. ▪ Removal of trees that could provide potential habitat for bats was conducted as part of the OC Loop project and a bat habitat assessment prior to tree removal and tree removal monitoring is not required. If requested, this would be provided under a separate scope and cost.
▪ This scope of work includes responding to one round of comments on submittals. If responses to additional comments are requested, GPA will provide an additional scope of work and budget to support this effort. ▪ We assume that no more than eight hours will be necessary for the Native American Coordination task. If additional time is necessary, a contract amendment will be warranted. ▪ A minimum half-day charge (“show up time”) per monitor will be charged for unannounced work stoppages that are not due to actions of DUKE CRM. Overtime (greater than eight hours per day) is extra and will be billed at 1.5 times the hourly rate
We look forward to continuing to work with you on this project to bring it to successful completion. Please contact me if you have any questions or comments.

Sincerely,

BIGGS CARDOSA

3. A signed repository agreement.

4. Field and laboratory methods that meet the curation requirements of the identified repository that will be implemented for monitoring, reporting, collection, and curation of collected specimens.

A Paleontological Mitigation Report (PMR) discussing findings and analysis will be prepared by a Principal Paleontologist upon completion of project earthmoving. The report will be included in the environmental Project file and also submitted to the curation facility. 162

Deliverables: One electronic copy of the PMP and PMR
Task 7: Native American Coordination
DUKE CRM will coordinate with the City representatives to assist the City to retain a local Native American Tribe for monitoring and consultation. This may include telephone conversations, video conferences, and email communications with City and Tribe, and review of documents between City and the Tribe. It is the City responsibility to contract directly with a Native American Tribe.

Task 8: Pre-Grade Meeting and Resource Awareness Training DUKE CRM will attend a pre-grade meeting will be held prior to ground disturbing activities. The City, Contractor, other sub-contractors, Native American monitor, DUKE CRM paleontologist and archaeologist will be in attendance. The Native American monitor and DUKE CRM staff will provide cultural/paleontological resource awareness training. The methods included in the PMP and communication protocols will be discussed. In addition, safety protocols for the project will also be discussed.

Task 9: Archaeological/Paleontological Monitoring
As stated in MM CUL-2 and CUL-4, archaeological monitoring will be full-time during all ground disturbing activities, and paleontological monitoring will begin when excavation reaches a depth of eight feet. DUKE CRM will provide one cross-trained archaeological/ paleontological monitor during all ground disturbing activities with the potential to impact archaeological resources. The monitor will follow construction equipment (dozers, scrapers, back hoes, etc.) observing the freshly excavated soils.

Monitoring will occur at the pace of construction. Occasionally the archaeological monitor will screen sediment for the presence of artifacts or ecofacts indicative of an archaeological site. In general, the archaeological monitor will stay at a safe distance from the construction equipment during monitoring, allowing construction to proceed at a normal pace. Occasionally the archaeological/paleontological monitor will need to inspect sediments in the area of the equipment, necessitating a temporary slowdown. However, all efforts will be made to limit slowdowns.

The archaeological/paleontological monitor will take daily photographs and maintain a daily log of monitoring activities. The daily log will include soils and stratigraphic discussion. The monitor will work under the direct supervision of the DUKE CRM project archaeologist. The archaeological/ paleontological monitor will work in coordination with the superintendent/foreman. If the archaeological/paleontological monitor discovers an archaeological/paleontological resource, he/she will notify the Project Paleontologist and/or Archaeologist, City, and Contractor, and follow the requirements in the PMP. Treatment of any discoveries will result in additional tasks not included herein and will necessitate a contract amendment.

For the purposes of this proposal, we anticipate four weeks/20 working days of ground disturbance and archaeological/paleontological monitoring. The actual number of monitoring days and the intensity (full-time, part-time, etc.) will be determined in the field and will be based on the actual schedule, sediment conditions, and assessment of the potential presence or absence of archaeological resources.

Additional monitoring will require a contract amendment. We assume negative findings for presence of archaeological and paleontological resources. This proposal does not include a Native American monitor.

If archaeological/paleontological resources are identified at any time during the project, the following tasks will likely occur and will require a contract amendment. These additional tasks would require a contract amendment.

1. All ground disturbance shall be halted. DUKE CRM shall be notified immediately. 163

2. DUKE CRM will notify the on-site Contractor, City, and Native American monitor immediately upon any such discovery. If the discovery is potentially significant, the City shall be notified.

3. The intensity of monitoring will likely need to increase (i.e., spot-check to part-time monitoring or part-time to full-time monitoring).

4. Following consultation with the City and Native Americans (as necessary), tasks that may be necessary include, but are not limited to: paleontological salvage, archaeological evaluation (testing) and/or data recovery excavation, sampling and processing, mapping, research, laboratory analysis, a detailed technical report, site records, and curation of specimens into a museum or curation facility. The level of effort for these tasks varies depending on the nature and significance of the find. All work be conducted in a manner consistent with the requirements of the PMP.

These additional tasks would require a contract amendment.

Task 5: Compliance Report
Following the completion of paleontological/archaeological monitoring and assuming negative findings, DUKE CRM will prepare a short compliance letter report that meets Caltrans requirement for a PMR.

The report will be submitted to the City. If significant artifacts are discovered, a more detailed report will need to be prepared; this cost is not included in our proposal and would require a contract amendment. If no paleontological/archaeological resources are identified during the monitoring activities, a letter report will be completed within 30 days of the completion of grading. The report will document the type of monitoring activities conducted, report any problems or issues that occurred, and state clearly that no resources were identified. It will include photographs and soils/stratigraphic discussions. All reports produced will be submitted to the City, and the SCCIC.

Deliverables: One electronic copy of the Compliance Report

ASSUMPTIONS
 The 404 Nationwide Permit is valid until March 14, 2026. If construction has initiated or is under contract to initiate by that date, the City has an additional 12 months to complete the project. It is assumed construction will be completed by March 14, 2027. If updates to the 404 permit are required, this would be provided under a separate scope and cost.  If construction is initiated by March 14, 2026 and completed by March 14, 2027, further coordination with the Regional Water Quality Control Board regarding the Water Quality Certification is not required.
 Per the California Department of Fish and Wildlife, a 1602 notification is not required for the project unless the project changes materially from what was submitted to CDFW in 2019. Therefore, updates to the 1602 permit are not required. If requested, this would be provided under a separate scope and cost.

 Because the regulatory agencies update their fees annually, GPA assumes the City will be responsible for direct payment of all regulatory permitting fees associated with the project.  Removal of trees that could provide potential habitat for bats was conducted as part of the OC Loop project and a bat habitat assessment prior to tree removal and tree removal monitoring is not required. If requested, this would be provided under a separate scope and cost.  Construction monitoring, other than monitoring initial installation of environmentally sensitive area fencing is not required for the project. If requested, this would be provided under a separate scope and cost.
10 164

 This scope of work includes responding to one round of comments on submittals. If responses to additional comments are requested, GPA will provide an additional scope of work and budget to support this effort.
 We assume that no more than eight hours will be necessary for the Native American Coordination task. If additional time is necessary, a contract amendment will be warranted.  A minimum half-day charge (“show up time”) per monitor will be charged for unannounced work stoppages that are not due to actions of DUKE CRM. Overtime (greater than eight hours per day) is extra and will be billed at 1.5 times the hourly rate.
