SUBJECT: Adopt a Resolution Awarding a Construction Contract to QA Constructor, Inc. for the Alves Street and Leighton Street Drainage Improvements, Project No. 07794, in the Amount of $132,250 and Approving an Administrative Change Order Budget of $32,750.
RECOMMENDATION
That the Council adopts a resolution (Attachment II) Awarding a construction contract for the Alves Street and Leighton Street Drainage Improvements Project to QA Constructors, Inc., in the amount of $132,250, and authorizing an administrative change order budget of $32,750 for a total not-to-exceed contract amount of $165,000.
SUMMARY
This Project proposes drainage improvements by constructing a valley gutter at the intersection of Alves Street and Leighton Street. The Project will also include street pavement grading at the intersection to allow for more optimal drainage from the residential houses to the valley gutter.
On April 23, 2024, the project received five (5) bids. Staff recommends that Council award the contract to the responsible low bidder, QA Constructors, Inc., of San Francisco, CA in the amount of $132,250 and authorizing an administrative change order budget of $32,750.
BACKGROUND
The Maintenance Services Department’s (MSD) Streets Division received numerous complaints of rainwater flooding the frontage of the properties at the intersection of Alves Street and Leighton Street. After the January 2023 heavy rainfall season, the property owners raised a concern that the water was pooling up the driveways. The adopted FY24 Capital Improvement Program budget includes a project budget appropriation of $250,000 (Fund 405) to address the concerns and develop a solution for the Alves Street and Leighton Street Drainage Improvements.
DISCUSSION
The as-built drawings for the project location show the surface runoff was intended to collect at the intersection of Alves Street and Leighton Street and continue flowing down Leighton Street to a storm drain catch basin on Silva Avenue. Currently, the surface runoff collects in front of driveways and gutters and does not continue flowing down Leighton Street. Upon investigation, the City determined that the street re-pavement process over the years created a crown at a higher elevation preventing the runoff from flowing toward Leighton Street. This project will re-grade the intersection in addition to adding a valley gutter to help mitigate the surface runoff towards Leighton Street.
Council approved the plans and specifications and call for bids on March 26, 2024. On April 23, 2024, five (5) bids were received ranging from $132,250 to $218,540. QA Constructors, Inc., of San Francisco, CA, submitted the lowest bid in the amount of $132,250, which was 20% lower than the Engineer’s Estimate of $165,000. Apena Engineering submitted the second lowest bid in the amount of $149,740, which is 9% lower than the Engineer’s Estimate.
This project is categorically exempt from environmental review pursuant to Section 15301(c) of the CEQA Guidelines because it is a project consisting of repair, maintenance or minor alteration of existing structures or facilities and involves negligible or no expansion of the existing use.
ECONOMIC IMPACT
Improvements to the intersection will eliminate the need for the MSD’s Streets Division to respond to neighborhood concerns and eliminate the need for the Division to use resources to frequently clean and maintain said area. The improvement of surface runoff will also prolong the life span of the sidewalk and roadway, especially since the roadway was repaved less than 10 years ago.
FISCAL IMPACT
The adopted FY24 CIP budget includes a project budget appropriation of $250,000 (Fund 405) to address the concerns and develop a solution for the Alves Street and Leighton Street Drainage Improvements.
The estimated project costs are as follows:
Construction Contract
$132,250
Contingencies
32,750
Design and Administration
35,000
Inspection, Survey, and Testing
50,000
TOTAL
$250,000
STRATEGIC ROADMAP
This agenda item supports the Strategic Priority of Invest in Infrastructure.
SUSTAINABILITY FEATURES
This project will improve the drainage flow in the neighborhood and reduce ponding. Reducing ponding will maximize the longevity of the new paved road, and will minimize the amount of resources needed to repair the road in the future.
PUBLIC CONTACT
Immediately after the construction contract is awarded, a preliminary notice explaining the project will be distributed to the residences adjacent to the limits of work. After the construction work has been scheduled, residents will be notified at least seven-two hours prior to actual commencement of work.
SCHEDULE
The estimated schedule for this project is as follows:
Award Construction Contract May 21, 2024
Begin Construction June 2024
Complete Construction July 2024
NEXT STEPS
After staff evaluates the bid results, staff will return to Council with the recommendation for award of the construction contract.
