Site work for a road / highway in San Francisco, California. Completed plans call for site work for a road / highway.

The objective of the project is to upgrade existing conductors along Transmission Line 7/8 to accommodate additional transmission power flows on them due to generators seeking interconnection on the neighboring California Independent System Operator (CAISO) system. This upgrade is based on the SFPUC and Hetch Hetchy Water and Power's (HHWP) affected system study process consistent with its obligation as a provider of electric transmission service and the CAISO's FERC-approved tariff. The work is to be performed in Stanislaus, California. There will be no bid discounts for this contract. The LBE Subcontracting Participation Requirement is 10.00%. Both San Francisco Small and Micro-LBEs and SFPUC-LBEs (Firms certified by SF Contract Monitoring Division) can be utilized to meet this requirement. The requirement is less than 20% because a large portion of work is comprised of procuring specialized electrical materials and equipment. The project also requires Electrical (C-10) licensed contractors specifically experienced in high voltage overhead electrical work. In addition, the location of the project is remote and there are limited subcontracting opportunities for the remainder of work that will not be performed by the Electrical (C-10) contractor. Please contact Vivian Liu at (415) 551-4814 and vivian.y.liu@sfgov.org for further information. Subcontracting opportunities may include, but not limited, to the following major types of work: excavation, trucking and hauling, traffic control, SWPPP, concrete, electrical, and structural steel framing. SFPUC encourages Bidders to submit a Safety Prequalification Form at least 3-weeks prior to the date of Bid opening.
