Port of San Francisco award memorandum; official project-limit plan
The Port of San Francisco selected Manson Construction Co. for Contract 2871, a USD 5,518,500 package to replace Pier 80's deteriorated makeshift fendering, remove timber fender piles, install new fenders and hardware, add mooring bollards and repair existing bollards. Resolution 25-25 also authorized a 10% contingency, taking total authority to USD 6,070,350. The award memorandum planned notice to proceed in August 2025 and substantial completion in August 2026, but those are baseline milestones: no cited official source confirms mobilisation, installed quantities, completion or acceptance.

Project anatomy
Contract scope and delivery roles
- Client / authority
- Port of San Francisco
- Delivery parties
- Manson Construction Co. - lowest responsive and responsible bidder authorized for award, Silverado Contractors Inc. - DataSF-reported project-team allocation of USD 1,167,000; performance not confirmed, Siteco Services, Inc. - DataSF-reported project-team allocation of USD 515,000; performance not confirmed, Transpacific Steel, LLC - DataSF-reported project-team allocation of USD 123,000; performance not confirmed
- Contract route
- The Port Commission authorized advertisement on 17 September 2024. The Port advertised Contract 2871 on 26 March 2025 and received four bids on 14 April. Manson's USD 5,518,500 bid ranked first ahead of Vortex Marine Construction, Power Engineering Construction and The Dutra Group. Resolution 25-25 authorized award on 13 May 2025 and confirmed that Manson met the 10% local-business participation goal.
- Execution window
- The award memorandum set a 365-consecutive-day duration from notice to proceed, with an August 2025 notice-to-proceed target and August 2026 substantial-completion target. Timber-pile removal was restricted to the June-November in-water work window. These dates are the award-stage baseline, not evidence that the notice to proceed was issued or that construction reached completion.
- Works package
- Remove the deteriorated pier-deck fendering and dilapidated timber fender piles; install a new fendering system, reaction structures and associated hardware; add mooring bollards at selected locations; and repair existing bollards. Bid documents also identify 29 supplied fenders including two spares, with 15 fenders and reaction walls on the East Berth, but final installed quantities remain unverified.
- Marine interfaces
- Pier 80 is an operating southern-waterfront terminal serving roll-on/roll-off and cargo vessels. The works are intended to accommodate a wider range of cargo ships and larger ocean-going cruise vessels. Delivery must be sequenced around tenant operations, and removal of timber piles from San Francisco Bay is subject to the regulated June-November in-water window.
- Commercial evidence boundary
- The confirmed award authorization is USD 5,518,500, with a separate USD 551,850 contingency and USD 6,070,350 total authority. CalSTA's Port and Freight Infrastructure Program supplies 80% and the Port Harbor Fund 20%. DataSF reports USD 1,805,000 of project-team allocations across Silverado, Siteco and Transpacific Steel, but those rows do not prove subcontract execution, payment or performance, and their linked prime-row amount does not supersede the Commission-authorized award.
