DISCUSSION
The Public Works Agency (PWA) is responsible for the administration and oversight of all Capital Improvement Projects in the City. PWA manages various types of construction projects, including street pavement rehabilitation, traffic signal installations, underground utilities, building improvements, bridges, and park facilities. These projects require independent materials testing and special inspections to verify compliance with approved plans, specifications, and applicable building and engineering standards.
Special inspections are required for certain types of construction activities such as welding and fire proofing.

The volume and technical specialization of these services exceed available in-house resources and, in many cases, require certified third-party testing and inspection.
Having specialized firms available on an as-needed basis to support the City’s construction management team is necessary to keep projects on schedule. The current agreements in place for these services expired on July 5, 2026 with an average annual expenditure of $800,000.
Staff recommends retaining testing and inspection firms to provide on-call quality assurance services during the construction of CIP projects. The selected firms will provide on-call testing and inspections that include code-required inspection of structural steel, concrete placement, masonry, welding, reinforcing steel, soils, asphalt, and other construction activities to verify compliance with applicable engineering and building standards.
Staff recommends procuring two separate sets of agreements, Federal and Non- Federal, to provide flexibility in administering projects funded through different sources.
Federally funded projects require consultants to comply with specific federal regulations and procurement requirements that typically result in higher costs. Maintaining both sets of agreements allows the City to assign work based on project funding requirements, ensure regulatory compliance, obtain best pricing, and streamline project delivery while minimizing procurement timelines and administrative costs.
Request for Proposals (RFP) No. 26-059A was issued on May 1, 2026 on the City’s online bid management and publication system.

Staff recommends awarding agreements to AESCO, Kleinfelder Inc., Koury Engineering & Testing, Inc., and Twining, Inc. (Exhibits 1 - 8), as the four firms achieved the highest overall scores and were determined to be the most qualified firms. The selected firms demonstrated extensive experience with public works construction projects, strong technical capabilities, qualified personnel, familiarity with Federal and Caltrans requirements, and the capacity to respond to multiple concurrent assignments.
Materials testing and inspection requests occur simultaneously on multiple projects and often require rapid response. Staff recommends multiple on-call firms to ensure adequate capacity, maintain project schedules, and allow work to be assigned based on consultant availability, expertise, and workload. Awarding agreements to four qualified firms will provide the City with sufficient capacity to support multiple concurrent construction projects, maintain project schedules, ensure compliance with applicable construction standards, and deliver quality assurance services in a timely and cost- effective manner.
ENVIRONMENTAL IMPACT
There is no environmental impact associated with this action.
FISCAL IMPACT
There is no fiscal impact at this time. These on-call agreements establish contractual authority only. Funding for individual task orders is approved by City Council through the annual operating and capital budgets, or other Council-approved budget actions when approving agreements, as applicable. Prior to utilizing any of these on-call services, Public Works Agency staff must obtain approval from the Finance and Management Services Agency (FMSA) by submitting a Notice to Proceed Request. This request must specify the funding source and the required dollar amount. FMSA will verify that the necessary funds are encumbered and available within the authorization and aggregate limits of these agreements. Once approved, PWA will issue a Notice to Proceed to the vendor detailing the specific scope of work and the maximum expenditure for the task.
