ANALYSIS
In September 2023, the City issued a Request for Proposal (RFP) for professional design and construction support services for the Annual Water and Sewer Main Replacements projects. The main elements of the scope of services include evaluating the proposed replacements, preparing California Environmental Quality Act ( CEQA) documents, developing design plans, preparing construction bid documents, and providing construction support. Staff posted the RFP on the City website and notified consultants about the opportunity. Two consultants submitted proposals, which were subsequently evaluated and ranked by a review panel consisting of Public Works staff. The panel selected BKF Engineers (BKF) as the most qualified firm based on the merits of their written proposal, experience in completing similar projects, and understanding of project goals.
The recommended not-to-exceed design contract amount of $719,100 includes $653,100 for basic services, including reimbursables, and $66,000 for additional services. Staff reviewed the proposed design fees and scopes of work in detail and considers the fees to be fair and reasonable. If the recommendations are approved, BKF can begin de sign in January 2024 and complete by spring 2025.
FISCAL IMPACT
Annual Water Main Replacements, Project 23 -08, is funded with $2,797,000 from the Water Capacity Fees Fund. Annual Sewer Main Replacements, Project 23-09, is funded with $1,750,000 from the Wastewater Capacity Fees Fund. If the recommendation is approved, the design of the Annual Water and Sewer Main Replacements will be funded with $359,550 from Project 23-08 and $359,550 from Project 23-09. There are sufficient funds for the recommended agreement, and no additional appropriations are required.
ALTERNATIVES
1. Do not approve the recommended agreement and direct staff to reissue an RFP.
2. Provide other direction.
