2. Concrete chloride ion content shall be determined by Testing Agency prior to placement. Cast samples from current production of concrete mix proposed for superstructure.

3. Concrete not meeting the requirements of paragraph “Water soluble chloride ion content of concrete…” above, shall contain appropriate amount of calcium nitrite.

Concrete supplier shall provide laboratory test results showing the amount of excess chloride ion content in the concrete mixture contributed by the aggregates.

For each pound of chloride ion in excess of the amount allowed, mix shall contain calcium nitrite (30 percent, plus or minus 2 percent, solids content) on one-to-one basis (one gallon of calcium nitrite for one lb. of excess chloride ion). Calcium nitrite used to offset chloride ions is in addition to calcium nitrite used as a corrosion inhibitor. Maximum of 1.5 lb. of chloride ion per cubic yard may be offset in this manner.

G. Admixtures: Use admixtures according to manufacturer’s written instructions.

1. Consider using water-reducing admixture or high-range water-reducing admixture (Superplasticizers), OR admixtures that achieve self-consolidating concrete, as required, for placement, workability, finishing and when required, increased flowability.

2. Consider using water-reducing and retarding admixture when required by high temperatures, low humidity, or other adverse placement conditions.

3. Use high range water-reducing admixture in pumped concrete, concrete for parking structure slabs, concrete required to be watertight, and concrete with a water-cementitious materials ratio of 0.45 or less. Use normal or mid-range water reducing admixture for concrete with water-cementitious materials ratio greater than 0.45.

4. Use corrosion-inhibiting admixture in concrete mixes where indicated.

H. When concrete mixture contains calcium nitrite admixture, (or other ionic salts that affect the chloride permeability test), perform rapid chloride permeability test for submitted mixture and for control sample. Control sample shall have the same mixture and watercementitious materials ratio as submitted mixture, except calcium nitrite admixture shall not be used.

I. Slump (ACI 301, Part 4 header “Slump”):

1. Maximum slump for concrete is indicated on Drawings. Where field conditions require slump to exceed that shown, increased slump shall be obtained by use of high range water reducers (superplasticizers) only, and Contractor shall obtain written acceptance from Engineer who may require an adjustment to mix.

2. All concrete containing high-range water-reducing admixture (superplasticizer) shall have a verified initial slump of 2– 3 in. Final slump after the addition of the superplasticizer shall be 6–9 in. as required by the contractor to properly place the concrete.

Statement of Project Understanding
SECTION 3 | PROJECT UNDERSTANDING AND APPROACH

STATEMENT OF PROJECT UNDERSTANDING
We understand that the City of Hermosa Beach is seeking proposals from qualified firms to provide comprehensive Construction Management and Inspection services for the upcoming CIP 699 – Parking Structure Lot “C” Improvements Project, slated for NTP in October of 2025. Per the CM RFP, construction work shall be completed within 75 working days of NTP. This parking structure is a three-story structure located at the corner of 13th Street and Hermosa Ave, situated a few blocks from the pier and a stones throw from the Strand, providing valuable parking to beach goers, patrons (and staff) of nearby restaurants and shops, as well as other nearby businesses. The structure is attached to multiple storefronts and is also the home to civic art installations. The selected consultant will assist the City’s Public Works Department to manage the project during pre-construction, construction, post construction, and close-out phases.

The goal of the overall project is to improve public safety and extend the lifespan of the structure by performing necessary repairs, preventative maintenance, and updates to lighting and electrical, through repairs and rehabilitation of concrete work, waterproofing enhancements, installing new guardrails, new barrier cables, installation of new sump pumps and a level transducers, power washing, restriping, conditioning of the air in the electrical room, as well as replacement of light fixtures, and various other repairs. The concrete repairs are needed on each type of structural member; beams, columns, walls, reinforced floor slab, ceiling, retaining wall, P/T slab; and vary from surficial stair nosing to provide reinforcement cover to partial and full depth repairs with significant reinforcement protection or rehabilitation required.

The scope of the selected consultant will be to provide a dedicated Construction Manager throughout the duration of the project who will be charged with stakeholder communication, project coordination, schedule and budget oversight, document control, as well as other miscellaneous tasks outlined in the RFP. The consultant may also provide Labor Compliance in accordance with CA Labor Code and Public Works Inspection. This is included in the fee as an optional task.

Approach to Work Program

APPROACH TO WORK PROGRAM (REQUIRED & OPTIONAL TASKS)

CONSTRUCTION MANAGEMENT
We acknowledge the full scope of services within the RFP. For the sake of brevity, are not repeating each bulleted item, we have extracted certain tasks for further discussion.

PROJECT MANAGEMENT & COORDINATION
• Manage and coordinate all aspects of the project inclusive of services identified in the Request for Proposal (RFP).
• Coordinate with City staff, regulatory agencies, and project stakeholders. • Notify the City immediately if the proposed work schedule does not conform to contract documents. • Ensure all relevant project communications are documented and promptly distributed. • Participate in field meetings and document issues, findings, direction, and changes. • Other improvements/activities as deemed necessary by the Consultant.’ Project management and stakeholder coordination are foundational to this project. To streamline oversight, we will assign clear roles and timelines at the project kickoff meeting. Internal coordination and stakeholder meetings will keep the project team aligned. To prevent administrative delays, we’ll use Procore for streamlined documentation and distribution. We will empower field and management staff with escalation protocols and decision trees to help quickly identify schedule risks and potential scope gaps, ensuring the City is notified immediately of any material issues. For discretionary or additional scope items, we will maintain a formal “register” for evaluation and prioritize only those improvements that align with City goals and available resources.

SCHEDULING & PROGRESS TRACKING
• Review Progress Schedule (Critical Path Method) and recommend for approval.

We will implement a structured Critical Path Method (CPM) schedule review process that includes a standardized checklist and variance analysis tools. Our team will conduct an initial review to verify compliance with contractual and constructability requirements and will then require updates for each 3 week look ahead.

COST MANAGEMENT & PAYMENTS
• Prepare independent cost estimates for changes.
• Evaluate merit of claims or requests for equitable adjustment. • Finalize record drawings, bid items, claims, change orders, and punch list.

Change orders and claims require detailed evaluation. Our team maintains a database of historical cost data and unit prices to produce rapid, defensible independent cost estimates. Claims and equitable adjustments will be evaluated using a structured internal process that includes fact-checking, schedule impact analysis, and contract alignment. Record reconciliation tasks will be handled progressively throughout the project to avoid end-of-project bottlenecks. This will include real-time updating of bid items and claim logs, so that final documentation and closeout materials are ready for delivery shortly after construction completion.

10 Construction Management and Inspection Services CIP 699 Parking Structure Lot “C” Improvements SECTION 3 | PROJECT UNDERSTANDING AND APPROACH
Approach to Work Program

CHANGE MANAGEMENT
• Identify scope for potential contract change orders and notify the City. • Prepare change orders in City format and submit for approval. • Assist the PM with change/claims negotiations and processing.

Effective change management begins in the field. We’ll use a “change trigger” checklist to help identify scope deviations or field condition issues early. Once identified, our team will prepare change orders using City-approved templates, ensuring consistent formatting and fast processing. Claims and negotiations will be supported through scheduled bi-weekly internal change meetings, allowing the team to prepare, evaluate, and finalize requests before submitting them to the City, reducing back-and-forth and delays.

CONSTRUCTION MONITORING & FIELD SUPPORT
• Review and approve material submittals.
• Review and coordinate approval of shop drawings with design consultant. • Review and approve construction contractor’s safety program. • Review and approve traffic control plans.
• Advise the City of complaints/inquiries and log their resolution. • Take and maintain regular construction documentation photographs. • Utilize software (e.g., Bluebeam, Procore) to link photos to plans and maintain photographic records. • Review contractor’s preconstruction videotape and prepare supplemental documentation.

Construction oversight tasks require timely, informed judgment to ensure the project proceeds safely and within design parameters. To manage submittals and shop drawings, we’ll use Procore and predefined checklists to expedite routine approvals and escalate those that need further involvement from the Engineer, City, or other staff. For public complaints and documentation, we will maintain a realtime log and issue tracking tool, ensuring all communications and resolutions are formally recorded. We will utilize mobile tools for uploading, tagging, and linking images to plan sets and/or daily reports. Our team can, if approved, also review preconstruction video documentation with supplemental stills and annotations to ensure a defensible record of pre-existing conditions.

CLOSEOUT & FINAL DELIVERABLES
• Coordinate final walk-through with stakeholders.
• Prepare punch list, certify project completion, and recommend acceptance.

Closeout requires timely, coordinated action to wrap up all aspects of the project. We will pre-schedule the final walkthrough with all stakeholders, following an internal pre-walk to ensure the site is ready for inspection. Punch list items will be triaged by severity, logged in a digital tracker, and monitored for resolution. Our team will document each correction with photos and update the City regularly, facilitating faster acceptance and turnover.

Approach to Work Program

COMPLIANCE, PERMITS & LEGAL OVERSIGHT
• Assist with contract interpretations and enforcement.

Maintaining compliance with contract terms is critical to mitigating risk. We implement a contract deviation log to track any proposed changes or ambiguities and escalate them for City review before proceeding. Our team will maintain a shared Q&A document to ensure consistent application of contract language across the team, and our CM will coordinate closely with the City on all interpretation and enforcement actions.

INSPECTION

CONSTRUCTION QUALITY & CONFORMANCE OVERSIGHT
• Regarding scope of work per Project’s contract documents, safety, traffic control, quality and quantity of work. Ensures Contractor’s adherence to the environmental and regulatory conditions of the contract. • Ensure Project construction is completed in accordance with approved plans, specifications, and estimate (PS&E) and referenced standards.
• In coordination with the CM and the City, resolve conflicts between plans and specifications and actual site conditions.
• Ensure that all materials incorporated into the work are acceptable and of good quality. Obtain Certificates of Compliance and/or complete field releases of material. • Closely monitor material and other necessary testing results and require the construction contractor to provide corrective measures to achieve compliance.
• Ensure compliance with applicable regulations controlling the work. • Maintain copies of all permits needed to construct the Project and enforce special requirements of each.
• Perform SWPPP compliance inspections and related duties. Document and take appropriate action to correct SWPPP or BMP deficiencies.
• Document that the required posters and wage rates are displayed at the job site.

Our inspectors play an active role in ensuring the contractor’s work aligns with the project scope, PS&E documents, and local, state, and/or federal regulations. To maintain control over construction quality, we will conduct thorough daily inspections, verify material compliance through certificates and field reviews, and enforce timely corrections for deficiencies. When critical activities begin we utilize field-level QA/QC checklists and track test results in real time to ensure immediate response to nonconforming items. Conflict resolution between plans and site conditions will be addressed collaboratively with the CM and City, utilizing a standardized escalation process for efficient resolution. Our team will not allow contract deviations without written and documented approval from the City. SWPPP/BMP compliance documentation will be verified regularly with photo evidence and reporting logs to ensure full regulatory adherence.

12 Construction Management and Inspection Services CIP 699 Parking Structure Lot “C” Improvements SECTION 3 | PROJECT UNDERSTANDING AND APPROACH
Approach to Work Program

FIELD DOCUMENTATION & REPORTING
• Maintain complete and accurate daily contract records (including photographs). Records shall be in the format requested by the City. Also, records should document any significant discussions or occurrences that occur in the field. Responsible for quantity measurements and calculations for work performed. • Complete daily measurements of quantities of work with the construction contractor and daily diaries. • Provide daily diaries reports to City or its designee on a weekly basis. • Maintain a daily diary which shall describe in detail all work accomplished on a daily basis, weather conditions, number of personnel employed, and labor classification, at the site by the construction contractor, quantities of materials incorporated into the project, quantities of bid item work completed, construction equipment at the site, deliveries of construction materials, material shortages, tests, labor disputes, general observations, and any unusual occurrences. • Document all contractor delays, reasons for delay, length of time for delay, and phases of work.

Field documentation is critical for verifying contractor performance, defending against claims, and managing payments. Our inspectors are trained to produce high-quality, complete daily reports, which will include photos, quantity calculations, narrative summaries, and weather data. Diaries and daily logs are completed in real-time and shared via Procore. Delay tracking will be handled with timestamped documentation and daily contractor coordination to ensure clarity around causes and duration. All field records will conform to City formatting requirements and will be compiled systematically for easy reference and audit.

CONSTRUCTION COORDINATION & COMMUNICATION
• Daily communication with the CM and the City on project status. • The Inspector shall visit the project site daily for the life of the project. • Coordinate with City staff and other Project stakeholders. • Attend all Project meetings such as preconstruction, field, and progress meetings. • Each working day, meet with the construction contractor to review proposed work plans, including specific details that may affect progress. Inform the CM and the City of any work which may result in a noteworthy impact to the City.
• Other related and required tasks.

Effective communication ensures proactive issue resolution and transparency. Our inspector will conduct daily site visits, communicate regularly with the CM and City staff, and attend all relevant project meetings. Each day will begin with a contractor coordination session to review upcoming work, identify potential concerns, and communicate potential impacts. Our team emphasizes responsiveness and availability, ensuring stakeholder trust and alignment throughout the life of the project.

MEASUREMENT & PAYMENT SUPPORT
• Prepare monthly quantity estimates for use in progress payments. • Provide complete and documented measurements and calculations to administer progress payments, change orders, extra work, etc.
• Assist in tracking approved changes for as-built records.

Our inspector will collect and verify field quantities daily in coordination with the contractor. These verified measurements will be compiled into a monthly quantity estimate package, complete with supporting documentation for use in payment processing. Any changes affecting as-built conditions will be tracked simultaneously to prevent rework at closeout. Our goal is to support accurate, timely, and defensible payment processing with minimal administrative lag.

Approach to Work Program

POTENTIAL ISSUES AND MITIGATION STRATEGIES

CONTRACTOR/SUBCONTRACTOR PERFORMANCE
Delivery of the project is ultimately dependent on the performance of the Contractor, and by extension, vital subcontractors. Lochner will help ensure the project’s success by setting the stage for accountability and transparency, and by making sure the plans and specifications make success a foregone conclusion.

The Contractor (and Subcontractors) should be incentivized to perform as contracted by including contract features such as the Performance Bond, Liquidated Damages, and stipulated schedule reporting requirements. Schedule shall show critical path items which will be pursued aggressively. Upon default, the Contractors bonding company will assume project ownership and will need to pursue completion of the project, but we want to avoid that condition as much as possible.

MATERIAL DELIVERIES
The availability of certain materials can pose a significant hurdle to project timelines, specifically as the “construction” season winds down and shortages may become problematic as projects make their final push for the year. The source and cost of in-demand products (steel, cement powder, wiring, etc…) may fluctuate between now and the start of construction. With this in mind, we suggest a limited NTP issued prior to constuction for any materials with long lead items. For critical materials, we suggest a maintaining an up to date source list and approved alternates that is reviewed an updated regularly to ensure timely completion of the project. We have enlisted Twining as a SME for this very reason, as they have the experience and industry knowledge to help forecast issues and guide the project to success.

Within the same breath, we also understand that staging space is limited and subject to loading (psf and gvwr) restrictions, which will require considerable cooperation and open communication with the contractor and surrounding community.

SUBCONTRACTOR COORDINATION
Often, specialty subcontractors will be scheduled on multiple projects simultaneously that result in delays to appearing on site and/or providing competent personnel. Our team will work with the Contractor to monitor Subcontractor performance and outlook, especially on the 3 week look ahead schedule. Problem Subcontractors may need to be replaced if necessary to maintain performance and schedule.

CONSTRUCTION MATERIALS (OPTIONAL TASKS)
With a project that has a tight timeline and a significant number of materials and materials types, any number of issues may arise that may affect ultimate schedule, even if addressed immediately. We understand that special inspection of the various activities is the responsibility of the contractor, per the specification, and materials testing is not a required scope. However, we feel that it is prudent to have a vetted and prequalified bench of experts (Twining) available to the project for decisive guidance and effective alternatives.

SECTION 4 | PROJECT MANAGEMENT PLAN
Lochner’s project management approach is rooted in disciplined execution, responsiveness, and accountability—principles that ensure the successful delivery of complex, multi-stakeholder capital programs.

COMMUNICATIONS APPROACH

TEAM OVERSIGHT AND COORDINATION
Our dedicated Construction Manager, Josh Stofle, will serve as the primary point of contact with the City of Hermosa Beach and will be responsible for day-to-day coordination, staff deployment, quality assurance, and performance monitoring. Zachary Wheeler will serve as high level support, coordination, and technical expertise to both Josh and the City, as will be available as needed to either. However, we believe that clear and direct communication at the project level builds accountability and provides for the most efficient path towards solutions. Josh will manage the consultant team using a centralized command structure with clear chains of responsibility, while maintaining flexible task delegation to accommodate shifting priorities across multiple task orders.

Each construction activity will begin with a formal Kick-Off, where the project team will discuss items specific to the assignment scope, schedule, and risk profile. Kick-offs will define scope deliverables, resource allocations, escalation paths, QA/QC procedures, and documentation workflows. With a tight schedule, setting clearly defined objectives and plans for the work sets the stage for success.

COMMUNICATION PROTOCOLS AND DOCUMENTATION (INCLUDING OPTIONAL TASKS) We implement a standardized communication protocol that includes:
• Weekly on-site (preferred) or virtual coordination meetings with the contractor and City (optional). • Bi-weekly on-site (preferred) or virtual stakeholder coordination meetings when multiple entities are involved.
• Daily on-site briefings between inspectors, contractors, and field leads. • Monthly progress review meetings including schedule and cost updates.

COMMUNITY OUTREACH AND ENGAGEMENT
We understand that Hermosa Beach is normally a resident sensitive city, however due to the proximity of the parking structure to the heart of Hermosa, there will be even more scrutiny on the impacts to resident life and overall schedule. The expected duration of 75 working days with an October 6, 2025 tentative start date will extend through the Thanksgiving and Winter Holidays. Our team understands this and has experience working and coordinating with impacted residents and businesses during and before construction to ensure that impacts are kept to a minimum and they are aware of and informed of upcoming work, potential closures and project issues as the project moves forward. As part of our standard suite of services, our CM and Inspectors will participate in handing out fliers, notices, receiving

Page 902 of 1055 ends

17 Construction Management and Inspection Services CIP 699 Parking Structure Lot “C” Improvements SECTION 4 | PROJECT MANAGEMENT PLAN
and addressing resident complaints, notifying the City of issues, and following up with the contractor to ensure they are addressing the needs of the community. While our Inspectors and Construction Managers have extensive experience working to inform the public and assuage concerns, as an optional task, we can pull from our planning staff to provide assistance to the City for Public Outreach and Awareness keeping the community informed of any / all impacts prior to and during the project construction activities. This may include planning and participating in community outreach events, material productions, and other tasks to be discussed if needed. RFI’s and submittals will be coordinated with the city and designer for quick responses and approvals so that when the construction starts, the contractor will be ready to perform and materials can be on hand or ordered. Our team understands the issues and concerns with this project and is ready to implement our time-tested management of projects with similar improvements to your project.

QUALITY ASSURANCE/QUALITY CONTROL APPROACH

RISK MANAGEMENT AND QA/QC
Our team integrates risk management into every phase of the project. Risk registers are developed for critical assignments, with defined mitigation strategies and response triggers. We apply earned value and schedule risk indicators to proactively flag issues and initiate corrective action. Dedicated QA/QC processes include timely reviews of submittals, RFIs, and field observations to ensure compliance with contract documents and regulatory requirements. Lochner staff will coordinate QA/QC activities on a daily basis per the project specifications and provisions and review activities as they happen, to make sure that QA/QC procedures are followed and deficiencies are resolved in a timely and efficient manner.

The CM will maintain a chronological log of all records. Rejected work will be thoroughly documented, photographed, and tracked until repaired or replaced to the satisfaction of the department. The primary objective of Lochner’s quality control program is to ensure that every aspect of the work is constructed in accordance with the contract documents and approved submittals, in compliance with the applicable code and to industry standards. In addition, that this work is performed consistent with the owner’s expectations.

SCHEDULE CONTROL AND DELAY MITIGATION
Our standard practice includes conducting schedule risk reviews during the pre-construction phase to identify schedule vulnerabilities and insert mitigation strategies such as resequencing work, expediting long-lead procurement, or redistributing labor. Delays are actively mitigated through early warning reports, trend analysis, and issue tracking logs maintained by the CM and verified through field inspections and contractor coordination.

COST FORECASTING AND CHANGE MANAGEMENT
Our team provides proactive cost forecasting using a combination of budget-to-actual tracking, contingency drawdown logs, and trend forecasting models. We work closely with the contractor to validate quantities, unit prices, and schedule-based payment applications. All change proposals and contractor claims are thoroughly reviewed for merit, cost reasonableness, and schedule impact before being submitted to the City for approval. We use structured logs to monitor pending changes and potential claims, ensuring budgetary impacts are captured early and clearly communicated.

Deliverables such as meeting agendas, minutes, daily construction reports, RFIs, submittals, change order logs, and monthly status reports will be prepared and submitted through Procore, in full compliance with City standards. Our administrative team ensures documentation is timely, complete, and audit-ready.

Relevant Experience and References
Lochner provided management services for both the design and construction phases of the project. During construction, an unexpected underground tunnel was discovered and had to be removed to allow for the development of the new five-story parking structure. The cost of removing the tunnel consumed 70% of the project contingency early on. To address this, we employed value engineering and proactive planning to revise the scope. As a result, the project was successfully completed under budget.

Relevant Experience and References
As part of Project Homekey, the City of Culver City was awarded a $26.6 million grant from the State of California and used $14.8 million for the acquisition and rehabilitation of two adjacent local motels, repurposing them into a total of 73 new housing units to address the unhoused population. This marks Culver City’s first Project Homekey initiative. The project took an innovative approach by co-locating both interim housing and longer-term supportive housing. It involved completely renovating all rooms to meet current code requirements, adding ADA accessible rooms, an on-site food warming kitchen, a laundry facility, and offices for social and mental health services.

Lochner provided project, construction management, and inspection services. Due to limited initial information, Lochner also managed finances and oversaw the contractor, effectively serving as the construction management team for the design-build project.
