3. Project Understanding &
Approach
PROJECT UNDERSTANDING & APPROACH
PROJECT MANAGEMENT
What sets 4Creeks apart from our competition is our ability to successfully manage large and complex projects. 4Creeks has a unique approach to overall project management that not only delivers projects to our agency clients on time and within budget, but fosters a collaborative partnership. At 4Creeks, we have developed what we call a "Project Status List". The main purpose of the Project Status List is to track critical path schedule items to ensure the project is delivered on time and to track funding and design tasks that need to be completed to make sure the end product meets the City's expectations and goals.
At project initiation, we will hold a project meeting with all internal project staff to develop a Project Task List that includes the tasks to be completed to bring the project to successful completion. This meeting will be led by our Senior staff and applicable department managers. We then hold meetings with other agencies involved with the project such as City staff, Caltrans, permitting agencies, ditch companies, utility companies, etc. to get a full understanding of everyone’s expectations and needs for the project. Our Project Status List is then filled out with all pertinent project data to provide a roadmap for successful project completion. This list is updated and added to throughout the project as new information arises. Throughout the project, our Project Manager and staff members use this Project Status List to develop monthly updates to the client, meeting agendas, meeting minutes, and other documents. Below is a generalized list of example topics that are tracked on our status lists. We customize tracked topics for each project to drive success.
• Funding Requirements – Tracks funding deadlines, major milestones, and out of the normal requirements. • Project Task List – Contains a list of tasks that need to be incorporated into the project for successful completion. • Agency Needs – Tracks items needed from the City so the Project Manager can diligently follow up. • Environmental Status – Typically broken into subsections to track CEQA and NEPA status and requirements along with special studies like historical, biological, cultural, or flood related. • Right of Way Status – We have found that this is best broken down into subsections by property owner. We maintain a general update of right of way acquisitions under this heading. • Utility Coordination – This is broken down into subsections by utility company. • Engineering Design – This is used to list all agency expectations/desires for the project that need to be incorporated into the design. Items are added to this list as the project progresses. Towards the 30% PS&E stage, our Project Manager will review this list along with the 30% PS&E to make sure the design complies with the agency’s expectations. • Permit Status – To track the status of pending permits needed from agencies that are impacted by the project. • Schedule – This section is tied to an overall Microsoft Project schedule that is maintained for the project duration. • Bidding Phase and Construction Assistance – Used on an as needed basis.
Consistent Project Communications
4Creeks believes in proactively communicating throughout the project lifecycle. For scheduled meetings, agendas are provided and meeting minutes are recorded to ensure accurate documentation of project directives and are distributed in a timely manner for review. We check in frequently and meet as necessary to ensure the project remains on schedule. The Project Manager will also remain available and responsive to the City for their questions, comments, and/or concerns.
Site Investigations and Data Collection
4Creeks staff will perform an initial site investigation of the project and begin discussions with the local utility companies. We will research and collect available information including utility plans, record drawings of existing facilities, and other relevant information. This information will be presented to the City at the project kick-off meeting. Throughout the project, our engineers will visit the site to verify the design will function properly with the surrounding improvements. These site visits help our design engineers produce higher quality plans, emphasizing constructibility.
INITIAL CITY KICK-OFF MEETING & COMPREHENSIVE WORK PLAN The 4Creeks Team will establish a comprehensive work plan and maintain that plan throughout the project. Since fees are based on the work required, the work plan clearly reflects the tasks, deliverables, and overall schedule. At the kick-off meeting, we will discuss the City's requirements and expectations for the project, including the following items:
• A detailed schedule that will incorporate the project tasks • Caltrans coordination and specific project requirements • Design and utility coordination issues
• Construction document layout
• Project expectations
• Responsibilities of each party
PRELIMINARY ENGINEERING PHASE
In this stage of the project, the 4Creeks Team will prepare the roadway preliminary horizontal alignment and analyze impacts to potential underground and overhead utility conflicts, impacts to properties adjacent to the project, interactions with existing, protected trees, right of way that is available for construction, connections with on-going City projects at the Walnut and State Route 198 intersections, evaluate planned roadway connections, determine impacts to existing, private access points, and potential FEMA flood zone issues. The horizontal alignment will be evaluated and updated based on input from City staff to determine the optimal alignment for the Shirk widening.
Once the optimal alignment has been determined, the need for interim connections to existing intersections will occur. If warranted, those interim connections will be horizontally designed and presented to the City for discussion and concurrence. The interim connection at County Road 198, if warranted, will be coordinated with CalTrans.
The Persian Ditch crossing and required improvements will be evaluated and coordinated with the Ditch Company. The existing alignment crosses Shirk at an acute angle and runs parallel to Shirk directly adjacent to the western road edge. Determining a preliminary alignment early in the design process will be critical to minimizing impact to the adjacent parcels.
Many of the members on our project team have extensive experience with FEMA’s National Flood Insurance Program and hydraulic calculations. Our experience includes hydraulic studies in Caltrans right of way, storm drain and drainage basin analysis, surface water hydrologic analysis with varying rainfall events, open and closed channel flow analysis, and water and sewer analysis.
Drainage impacts of the proposed improvements will be preliminarily evaluated and understood for future design considerations. 30% ENGINEERING DESIGN PHASE
Construction Drawings
4Creeks and it's team members have excellent reputations for preparing comprehensive and biddable sets of construction documents. This is achieved through in-house and team member reviews at set milestones during the preparation of construction documents. Construction Plans will be submitted to the City at 30% and are understood to become the basis of the subsequent 65%, 90%, and 100% construction plan sets. Review, comments, and value engineering of the design are anticipated to occur through monthly meetings, design exhibits, and coordination efforts. Modifications to the plans are easily accommodated at each milestone, resulting in plans that will allow for the future clear, biddable set of final construction documents. Additionally, we will prepare a Roadway Memorandum discussing project history, the design process, next steps, and outline design constraints.
Cost Estimation and Phasing Programs
As a design-build firm, 4Creeks has a unique ability to understand and track dynamic material and labor costs. Controlling the cost of a project is extremely important. The 4Creeks Team tracks costs on each project it undertakes to ensure costs are quantified for future reference. This is accomplished by utilizing the following sources of information for unit prices and project costs:
• Historic cost data received by our team and the City for similar projects • Strong working relationships with public sector contractors • Track records of performance and cost data obtained from industry and manufacturers’ representatives Our estimation process is based on the development of an initial construction cost using the above noted sources. This budget can be used to determine the project’s design elements and features. Our experience will be leveraged to provide a best estimate for the projects 30% engineer's cost estimate to allow the City to anticipate construction funding needs.
The 30% engineer's cost estimate will include costs for right-of-way and easement acquisition and for dry utility relocations based upon pricing from previous projects. It is understood that estimated costs may not capture all costs specific for this project since acquisition negotiations and final dry utility design will not be completed.
QUALITY ASSURANCE AND CONTROL
The ultimate success of any project hinges on the solid foundation of its leadership and management methodologies and procedures. Quality assurance and control are
paramount on every project we undertake. Essential elements of our quality assurance and control procedures can be
summarized as follows:
• Establishment of a detailed and comprehensive work
plan - Project Status List
• Task-specific project schedule that identifies key
milestones and deliverables
• Budget review and control to eliminate "scope creep"
• Project management of internal staff and sub-
consultant team members
• Consistent project communications (agendas,
meeting minutes, status reports)
• Consistent proactive communication with the City's
Project Manager/Staff
• Document preparation standards
• Agency submittal checklist and procedures
• Internal document review and plan checking
procedures by multiple qualified and licensed
engineers
• Thorough cross checking between all sub-consultant
documents for consistency
PROJECT CHALLENGES AND CRITICAL TASKS
Many projects maintain similar elements, but each has its own unique set of considerations and challenges. Among those that stand out for the Shirk Road Widening project, are the following:
• Obtaining permissions from adjoining property owners. Relational/people issues can quickly lend themselves to more surprises and challenges than even technical problems. This requires clear and honest communication, patience with all questions and concerns, and a strict adherence to agreed upon schedules. • Conducting an interim and future intersection analysis. While not uncommon, these analyses can sometimes prove to be rather complicated. 4Creeks approaches problems from multiple perspectives simultaneously (regulation, engineering, constructibility, cost-effectiveness, etc.). As a result, understanding the current conditions and the future improvements and goals is imperative and leaning on our experience and knowledge of the area is critical. • Existing encumbrances are within the anticipated corridor and will impact the design and the efforts to maintain minimum construction costs. Those encumbrances include existing wet and dry utilities, the Persian Ditch, access points, and trees that may require protection or augmentation. These encumbrances will be vetted early within the design process.
• It is anticipated that the City Arborist will perform a tree survey to verify the tree types, value, and protection requirements along the Shirk Road corridor and that finding will be available prior to the Project Kick-off meeting. Tree protection will drive, in part, the Shirk Road alignment and all trees are anticipated to be depicted within the City's provided survey. • Dry utilities within the project area may impact the design and construction time frames. In an effort to expedite this project and to validate dry utility encumbrances, 4Creeks will request a rights check with Southern California Edison separate from the relocation process early in the 30% efforts. This process requires a fee, which will be passed along to the City for payment and is not included within the design fee. • The 30% documents will depict the existing trees as identified by the City Arborist and will call out trees for removal and replacement and/or protection in place.
• The City has updated the storm drain master plan and 4Creeks will work with the City's master plan and its application to the project. 4Creeks will identify the basin location and will provide a 30% design for the basin to facilitate land acquisition and storm sewer system design.
4. Proposed Scope of Work
PROPOSED SCOPE OF WORK
The Scope of Work outlined herein is based on conversations with City staff, our expertise, and review of available documentation.
We will work with City staff to refine the scope, if needed, to tailor our design and deliverables to meet expectations. Additionally, after project kickoff and during the design phase, we will notify the City if unexpected field conditions, encumbrances, or design requirements necessitate a change order. The general scope of work presented herein, is for the 30% design of the Shirk Road improvements between Walnut Road and the State Route 198 Interchange. For the purposes of our proposal and associated design, we anticipate the southern project limit to be the connection at the northern curb returns of the planned improvements at the Walnut Road intersection, currently under design by others. The northern project limits are anticipated to be the southern access ramps of the State Route 198 intersection, which will require an interim design to tie to existing conditions and an ultimate design for the four (4) thru lane section. We understand that Shirk Road is anticipated to be a 110’ Rights-Of-Way, Arterial Road standard section with a Class I bike lane, per the City’s planning map. 4Creeks will use a number of staff members and sub-consultants to perform the various components of this project. Our Project Manager will coordinate with all staff members to work concurrently to achieve timely results and meet the project goals.
Task 1: Project Management
4Creeks will manage project tasks including work needed to:
• Lead, direct, coordinate, and monitor the team
• Prepare for, attend, and document project kick-off
meeting, field review, alignment selection meeting,
monthly team meetings, and action items
• Prepare, coordinate, and maintain a critical path
method schedule using MS Project or accepted
alternative, including identifying major delivery
milestones and tasks
• Miscellaneous coordination and support including
assisting the City with meetings and coordination
efforts with the Dry Utility Companies, the Persian
Ditch, Caltrans, and adjacent property owners
• Prepare monthly invoices including a summary of
specific work completed (including breakdown of
hours by task to assist City with budget tracking)
• Prepare monthly progress reports (to be submitted
with monthly invoices) including discussion of critical items or decisions, recommendations to address
items, work accomplished during that month, and
anticipated work for the following month
Project development team (PDT) virtual meetings will be held monthly between the 4Creeks, City, and sub-consultants (as needed). 4Creeks will prepare and distribute the meeting agenda including ensuring all necessary participants are invited and have access to join the meeting (for virtual meetings) including arranging all meeting times, locations, etc. 4Creeks will prepare and distribute meeting minutes to all participants within five working days after the meeting. The meeting minutes shall include an updated schedule, if
necessary, and a list of “Action Items” explaining the action, when it is due, who is responsible, and the date it was completed.
4Creeks will have a quality control plan for the Project to ensure design calculations, exhibits, plans, reports, etc. are independently checked, corrected, and “back-checked” for accuracy, completeness, and constructibility.
Task 2: Surveys, Mapping, and Right-
of-Way
4Creeks anticipates the City will provide the topo surveying and mapping for this project. However, we understand we will perform a topographic base map check and base file set up for use during the design process. It is anticipated that the horizontal datum used in surveying and mapping shall be the California Coordinate System of 1983 (CCS83), Zone IV, using the latest published epoch from either the California Spatial Reference Center or the National Geodetic Survey datum. The elevation shall be based on the North American Vertical Datum of 1988 (NAVD88 or the City's current datum
implemented on the provided topo survey and mapping) and if a GEOID model is used, it shall be the latest published model.
Task 2.1 Project Survey Control
Prepare a base map, in imperial units, showing property boundaries, easements, rights-of-way, existing utilities and topographic information provided by the City. 4Creeks will prepare the base sheet in accordance with City CAD
standards.
Task 2.2 Right-of-Way Acquisition Support
It is assumed that a total of nine (9) privately owned parcels could potentially be impacted by the project. This task shall include assisting the City with the understanding of the anticipated right-of-way acquisition required with an overall exhibit that will identify the ROW required and anticipated easements for utilities, drainage, slope, temporary
construction, and any other acquisition required to implement the project. It is anticipated that a total of nine (9) basic graphical drawings (one drawing for each parcel impacted by the project) will be generated to present to
property owners illustrating anticipated project impacts including but not limited to impacts to: trees, landscaping features, fencing, driveways, structures, farmland, and mailboxes based upon the information within the City
provided topographic survey. It is understood that all
communication, discussions, and acquisition negotiations shall be the responsibility of the City and that 4Creeks is strictly providing the supporting exhibits outlined herein.
Task 2.3 Potholing Existing Force Main
The existing force main within Shirk will be potholed
horizontally and vertically to locate the utility and verify the design constraint. One (1) day of potholing is included to provide approximately eight (8) potholes within the
anticipated alignment at assumed critical design locations, including potholes, disposition, backfilling, and traffic control. 30% Design Additional Services
Additional services are services that may be provided to the City, if requested, that are not a portion of the initial scope and fee. Those potential services for the Survey, Mapping and Rights-of-Way Task are as follows:
• Acquisition Staking
• Supplemental Survey, including Topo Survey
• Encroachment Permits
• Permission to Enter Private Property
• Property Surveys and Resolution
• Utility Mapping
• Title Review
• Additional Potholing
Task 3: Preliminary Engineering
(30% PS&E)
Task 3.1 Prepare Preliminary Design
This task includes work required to develop preliminary roadway geometrics, proposed water, sanitary and storm
main alignments, the Persian Ditch crossing, existing access points, the anticipated W Tulare Ave intersection, the W Noble Ave frontage road intersection, and the existing sewer force main alternatives, as well as, the development of a preferred project design concept for budgeting and for future funding purposes, environmental approval, permitting, and final design. This work includes the following:
Prepare Planning Study Drawing
Prepare drawings that include roadway widening plan/profile inclusive of horizontal design on wet utilities. Plans will be prepared in conformance with City and AASHTO (“A Policy on Geometric Design of Highways and Streets”) standards. The Planning Study Drawing will provide the basis for the 30% Construction Plan documents.
Prepare 30% Construction Drawings
Prepare 30% construction drawings that include a cover sheet, general notes, typical sections, topo and demo plans, utilities and potholing plan, improvement plan and profiles, signing and striping plans, street light plans, intersection/ramp design, irrigation ditch (Persian Ditch) modification plans, and detail sheets. The 30% construction plans will develop thehorizontal design and basic vertical design of the proposed or impacted improvements. Dry utilities will be researched with facilities cataloged within the project corridor. Our team will work with those utility owners to understand project impacts and
provide preliminary design.
Task 3.2 Drainage and Hydraulics
Drainage analysis shall be performed for the project to determine and evaluate the impacts of the Shirk widening. The City has updated the storm drain master plan and 4Creeks will work with the City's master plan and its application to the project. Drainage sub-basins and the preliminary storm sizes and locations will be implemented and tailored to the 30% design. The basin required to support the widening will be located and preliminarily designed to facilitate land
acquisition and storm sewer system design. A preliminary storm sewer system will be developed to meet City
requirements with preliminary pipe and inlet sizes determined.
Existing off-site drainage patterns will be reviewed for potential impacts and a general review of any FEMA
floodplains to support 65%, 90%, and final construction plan efforts will occur. No FEMA modeling or processing is
anticipated with the 30% design. A drainage memorandum will be generated outlining calculations performed and next steps.
Task 3.3 Utility Coordination Services
Shall include utility research through requesting and review all dry utility maps in the area, coordination with the utility companies about known future infrastructure within the
project limits, and update the project base files, as needed.
Utility applications will include submitting improvement plans and applications to the impacted utility companies and
coordinate relocations, removals or upgrade service of
existing facilities within the proposed project limits. Utility redlines will occur in the form of obtaining on-site point-of- connection locations for the project, determine conduit requirements and joint trench route from the utility
companies, and obtain utility company designs on behalf of the City.
4Creeks will request a rights check with Southern California Edison separate from the relocation process early in the 30% efforts. This process requires a fee, which will be passed along to the City for payment. Furthermore, coordination with CalWater will occur to determine water main infrastructure requirements to accommodate the future main alignment
within the street section, if any.
A budget has been provided within this scope and fee to address optional potholing to locate utilities within the roadway corridor that may create a design constraint. Since the number of utilities and potholing needs are unknown at this time, the optional potholing line item assumes three (3) additional days of potholing to obtain information, if directed by the City.
Task 3.4 Preliminary Traffic Signal Design
4Creeks will generate the preliminary traffic signal design at the intersection of Shirk Road and Tulare Avenue. It is assumed that Shirk Road and Tulare Avenue will be developed as a "T" intersection and may be modified to extend Tulare west in the future. The preliminary design will be generated to
accommodate the proposed T and the future, assumed Tulare Avenue extension at a scale of 1" = 20' and will layout the signal phase diagram, controller assembly, equipment enclosure, signal heads, video detection system, emergency vehicle preemption equipment, conduits and cables and will provide the equipment and conduit schedules, based on City provided standards. The preliminary design excludes traffic counts, signal warrant studies, interconnect or fiber system designs, and signal timing plan.
Task 3.5 Prepare Preliminary Cost Estimate
Prepare engineer’s estimate of probable cost. Costs will be based on preliminary quantities developed in general
conformance with City requirements and shall include a
contingency amount of 25% or as directed by City staff.
