Sir Francis Drake Blvd Corridor Rehabilitation
Ghilotti Bros. was hired to rehabilitate Sir Francis Drake Boulevard – an existing heavily trafficked four-lane thoroughfare in an urban setting. This project consisted of repaving, safety improvements for pedestrians and cyclists, striping, intersection and signal improvements, traffic operation improvements, utility infrastructure improvements, landscaping, and new street lighting. These included intersection geometry modifications, including adding or reconfiguring turn lanes as well as removal or relocation of medians. It also included revised pavement striping and signage designed to improve safety for motorists, pedestrians, and bicyclists along with sidewalk widening and crosswalk enhancements designed to improve pedestrian safety and access. The project also upgraded the public water main operated by Marin Municipal Water District (MMWD) along SFDB and included approximately 11,880 LF of directionally drilled electrical conduit.
Through partnering, value engineering, and accelerations, this project was completed 3-months ahead of schedule and within 3% of the fixed price despite significant unknowns and conflicts with the design. Value engineering was able to offset much of the additional costs resulting from unknowns.
