RECOMMENDATION
Recommendation
It is recommended that the City Council, by motion, accept the construction improvements of the Oyster Point Boulevard Sanitary Sewer Main Reconstruction Project (No. ss2401, Bid No. 2690) as complete in accordance with plans and specifications at a total construction cost of $4,370,869.80.
Body
BACKGROUND/DISCUSSION
On May 28, 2025, the City awarded a construction contract to K.J. Woods Construction, Inc. to upsize the existing sanitary sewer main along Oyster Point Boulevard, from Gull Drive to the sanitary sewer pump station at Gateway Boulevard, by installing a new 18-inch high-density polyethylene (HDPE) standard dimension ratio (SDR) -17 pipeline to replace the existing 10-inch sewer main.
The project was identified through the City’s Sanitary Sewer Master Plan as a critical capacity improvement needed to accommodate peak wet-weather flows and support the long-term reliability of the wastewater collection system. The existing 10-inch sewer main represented a hydraulic bottleneck within the system and had the potential to contribute to surcharging and sanitary sewer overflows during significant storm events.
Completion of the project has increased conveyance capacity within this section of the sanitary sewer system, reducing the risk of sanitary sewer overflows and improving system reliability during peak wet-weather conditions. The project also supports the City’s ongoing efforts to maintain regulatory compliance and protect public health and the environment.
In addition, the project included asphalt road grind-and-overlay and restriping of the eastbound travel lanes on Oyster Point Boulevard and a portion of Veterans Boulevard, enhancing roadway conditions, extending pavement life, and improving traffic safety for motorists and bicyclists.
During construction, modifications to the original scope were required to address unforeseen field conditions, including utility conflicts that necessitated redesigning portions of the pipeline installation from an open-cut method to a trenchless jack-and-bore method. These adjustments were accommodated through the project contingency and balancing changes to bid item quantities.
The work was inspected by the Engineering Division throughout construction and was found to be complete and in conformance with the plans, specifications, and contract documents as of May 21, 2026.
Project location map and photos are included as Attachments 1 and 2, respectively, of this staff report.
FISCAL IMPACT
This project is funded by the East of 101 Sewer Impact Fee Fund included in the City of South San Francisco’s Fiscal Year 2024-25 Capital Improvement Program (Project No. ss2401).
The total construction cost incurred for the project is summarized as follows:
|
|
Projected |
Actual |
|
Construction Contract |
$4,588,000.00 |
$4,588,000.00 |
|
Construction Contingency |
$ 932,000.00 |
($ 217,130.20) |
|
Total Construction Budget |
$5,520,000.00 |
$ 4,370,869.80 |
Construction contingency funds were utilized for work outside the original scope, including the aforementioned redesign of a portion of the pipeline installation from an open-cut method to a trenchless jack-and-bore method due to unforeseen utility conflicts. The contingency also accounted for adjustments to final bid item quantities, including reductions in quantities for work that were ultimately not required.
RELATIONSHIP TO CITY COUNCIL PRIORITIES ACTION PLAN
Approval of this action will contribute to the City Council’s Priorities Action Plan Major Focus Area of Quality of Life by maintaining and improving infrastructure to serve the public.
CONCLUSION
Staff recommend acceptance of the project as complete. Upon acceptance, a Notice of Completion will be filed with the County of San Mateo Recorder’s office. At the end of the thirty-day lien period, the retention funds will be released to the Contractor after the City receives the one-year warranty bond.
