Body
BACKGROUND/DISCUSSION
On October 20, 2018, the City awarded a construction contract to G. Bortolotto & Co., Inc. to rehabilitate approximately 170,000 square yards of City streets with the application of asphalt surface sealer: a mixture of polymer modified asphalt emulsion, mineral aggregate, mineral filler, water, concrete, and other additives. The work included removal of vegetation, debris and pavement striping and marking on streets, repairs of concrete curbs and gutters and structural pavement failures, application of the slurry seal mixture, replacement of striping and pavement markings, and street sweeping. The work was inspected by the Engineering Division and found to be complete in accordance with the contract documents as of June 7, 2019. Location map and photos are included in the Attachment 1 of this staff report.
FISCAL IMPACT
This project is funded by the Measure W and OBAG 2 funds, and the project is included in the City of South San Francisco’s Fiscal Year 2018-19 Capital Improvement Program (Project No. st1903) with sufficient funds allocated to cover the project cost. The total construction cost incurred for the project is summarized as follows:
Projected Actual
G. Bortolotto & Co., Inc. Contract $1,179,717 $1,179,717.00
Construction Contingency $120,283 $22,647.32
Total Construction Budget $1,300,000 $1,202,364.32
Contingency was used for re-posting of No Parking signs that were vandalized, additional notifications (door hanger) for residents on streets with required repairs, and for pavement striping that was added after the bid to enhance the project area.
RELATIONSHIP TO STRATEGIC PLAN
The project is consistent with the City’s Strategic Plan initiative to build and maintain a sustainable city.
CONCLUSION
Staff recommends 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 has received a one-year warranty bond.
It is recommended that the City Council, by motion, accept the construction improvements of the Slurry Seal Project (CIP Project No. st1903a) as complete in accordance with plans and specifications (Total Construction Cost $1,202,364.32).
