PROJECT DESCRIPTION
The City of Santa Clarita (client) is requesting additional services at the Via Princessa Park project located in Santa Clarita, CA. The civil engineering scope is to include construction support for Phase 1A of the project which will be provided by Psomas (consultant) and Railpros (subconsultant).
Ninyo & Moore (subconsultant) will be providing geotechnical, materials testing, and special inspection services. Ninyo & Moore’s proposal is attached as Exhibit “B.” Psomas will also be providing field verification surveying services. QSP services are also provided, which include QSP Stormwater Pollution Prevention Plan Monitoring Services as provided by EcoKai and attached as Exhibit “C.”
SCOPE OF WORK
Psomas agrees to furnish and perform the various professional services pertinent to the project specifically outlined as follows:
Construction Meetings and Support
• Attend Pre-Construction Meeting.
• Attend weekly jobsite meetings and job inspection visits. • Respond to RFI’s and review submittals and shop drawings. • Prepare construction bulletins as needed.
• Prepare construction correction notices as needed.
• Assist with reviewing, analyzing, and advising the city on contract change order requests. • Perform final review and contribute to the punch list with the contractor.
We have assumed a budget allotment of approximately two hundred (200) hours for this scope of work.
As-Built Plan
Consultant shall prepare as-built drawings upon completion of the project and acquire the contractor’s daily red lined plans from the contractor and their subcontractors. Final Record Drawing will need to be both in electronic files (CAD and PDF) and hard copies. This subtask shall be noted as a separate line item.
Coordination with SCRRA (Railpros)
Railpros will provide construction support services on a time and material basis. Their services will include coordination with SCRRA, the city, contractor, and the design team as it relates to railroad access and work adjacent to the rail right of way.

Field Verification Surveying
Field verification for staking and/or constructed improvements, as needed, and only as specifically requested by client. This work is to be executed in four (4) or eight (8) hour mobilizations of a two (2) person survey crew, for a total no greater than forty (40) hours.
100% PSE Restart
Psomas and the design team have been asked to restart the project at the 100% PSE phase of the project. The project was put on hold on April 29, 2024. Due to the long pause (17 months) in schedule, we kindly ask for a restart fee to cover the design team’s efforts to reengage in the project. The estimated timeframe for the restart is two (2) weeks of effort to pick the project up where it left off at 90% plan check. The restart fee will be split among the design team consultants including Psomas, PCLD, AVA, and PACE.
QSP Stormwater Pollution Prevention Plan Monitoring (EcoKai) Scope of work is outlined in EcoKai’s proposal, attached, as Exhibit “C.”
OWNER’S ALLOWANCE ITEMS
This item is to provide an owner’s allowance for items that may require additional budget due to construction delays. Items that may come up include additional construction support and geotechnical testing services.
Additionally, there has been discussion with the city regarding a further phasing of the project into Phase IB and Phase II. That effort could involve modifying existing plans, creating separate Phase IB specs, cost estimate, and bid schedule, additional project management and coordination, and additional bid support.

The services of outside consultants will be charged at cost plus fifteen percent.
The above rate schedule is for straight time. Overtime will be charged at 135 percent of the standard hourly rates.
Work performed on Sundays and holidays will be charged at 170 percent of the standard hourly rates.
Billing Policies and Procedures
The relationship with our client works best when there is a mutual understanding about fees and payment terms. You are encouraged to discuss with us any questions you may have concerning these policies.
Billing
The value of our services is determined primarily by the time spent on each client matter. Our time records are kept on a weekly basis and invoices are prepared every four or five weeks, depending on our accounting calendar.
Payments
As there is a time lag between rendering professional services and mailing our bills, all invoices are due upon presentation. Any bills that are not paid within thirty days are classified as “delinquent,” and a late charge of 1-1/2 % per month will be added.
Work Stoppage
Work will be stopped on any job that has invoices outstanding for more than 60 days. Due to the costs and inefficiencies that results from stopping and restarting a job, an additional “start-up charge” will be assessed.
Retainers
It is our policy to obtain an advance retainer from all new clients and from exiting clients under certain circumstances. Also, it occasionally may be appropriate to require an advance retainer after the commencement of a project or to require an increase in a prior retainer. This depends in part on our client’s payment history and the scope of the work involved.
Reimbursable Expenses
Costs, other than time charges, are based on usage. Therefore, the cost of blueprinting, messenger service, transportation, and other specific job related costs are charges as “reimbursable expenses.” Generally, these are a very small portion of the total cost of a project. If requested, we will provide a computer printout which details these costs. We do not provide any additional backup for these generally nominal expenses.

Dear Mr. Johnson:
Ninyo & Moore is pleased to submit this proposal for geotechnical and materials testing services during construction of the Via Princessa Park Phase IA Rough Grading Project located at 19201 Via Princessa in Santa Clarita, California. Based on our review of the project plans and our previous work at the site, we understand that the project will generally consist of rough grading for the Via Princess Park. Cut will be generated from the proposed Best Management Practice Structure on the west side of Honby Channel. The cut will be placed as documented engineered fill within the proposed Park Site on the east side of Honby Channel. The fill placed will be within the sports field areas that will be completed in later phases . Prior to fill placement, approximately 3 feet of undocumented fill and loose/weak alluvium will be removed and replaced as documented engineered fill.
Excavation and fill activities are anticipated to be withi n 20 feet of existing mobile home residential structures to the east of the project boundary . The City of Santa Clarita has requested vibration monitoring services for the adjacent residential structures that includes a preconstruction survey of the exterior conditions of the residential structures.
We are assuming an 8-week schedule for Phase 1A rough grading that includes 4 week s of Vibration monitoring.
SCOPE OF SERVICES
Vibration Monitoring
Based on our conversations with you, our understanding of the proposed construction, and our experience with similar projects, we propose to provide the following scope of services for vibration monitoring:
EXHIBIT "B"
Ninyo & Moore | Via Princessa Park – Phase 1A Rough Grading, Santa Clarita, California | 212109001 | September 25, 2025 2
• Performance of a pre-construction survey of up to 20 residential structures. to establish a baseline set of conditions at the site and adjacent residences prior to the proposed construction. The pre - construction survey would include photo-documentation of geotechnical conditions of the site and exterior areas of the neighboring properties, and measurements of existing geotechnical features.
If pre -construction surveys of the interior conditions are required, this may be provided for an additional fee.
• Performance of vibration monitoring at four (4) locations. Vibr ation monitors will be installed adjacent to the residential structures. Locations of the vibration monitors will be determined following discussions with representatives from the City of Santa Clarita and the neighboring property owners. The vibration mon itoring equipment is powered by internal batteries and will provide continuous operations with wireless transmission of vibration data to project personnel. • Review and analysis of transmitted vibration data. Text and/or email alerts will be sent to designated project personnel when vibration readings greater than the agreed upon alert threshold are recorded.
• Construction activities and existing conditions will be monitored by onsite Ninyo & Moore personnel. Field activity logs will record general construction activities and any activity considered potentially able to produce relatively large impulses or vibration signals. • Project coordination, management and technical support including review of the project plans and specifications, work scheduling and distribution of test data. • Attendance at pre-construction meetings and as-requested field meetings. • Advise on locations for City’s surveyor to set control points for settlement monitoring during construction activities. Guidance for frequency for checking control points will also be provided. • Photo documentation during construction and post construction.
Geotechnical and Materials Testing Services
Based on our conversations with Psomas, our understanding of the proposed construction, and our experience with similar projects, we propose to provide the following scope of services for geotechnical and materials testing services:
• Project coordination, management and technical support including review of the project geotechnical reports, plans and specifications, work scheduling and distribution of test data. • Attendance at pre-construction meetings and as-requested field meetings. • Field Senior Project Engineer/Geologist services for observation of remedial excavation bottoms and foundation excavations. Written supplemental recommendations will be provided as needed. • Field Technician services to provide observation, sampling and testing during earthwork operations. Field density tests will be performed to evaluate the Contractor’s compaction efforts. • Preparation of daily reports, test data sheets, and field memoranda to document the items inspected and tested.
