Opportunity
To obtain competitive, cost-effective bids, it’s important to prepare contract documents with the necessary attention to detail. This was a key challenge in restoring the seawall and waterfront of Mission Bay in San Francisco.
Solution
On behalf of the Port of San Francisco, Mott MacDonald provided civil and coastal engineering design and construction administration to stabilise and repair the existing seawall and construct a shoreline protection structure at Bayfront Park that would prevent future erosion of upland areas.
Approximately 300 feet (91 meters) of seawall required stabilization and 1,000 feet (305 meters) of shoreline required protection. The preferred alternative consisted of controlled low strength material and a new stone revetment.
Outcome
Our careful approach helped control costs on this important project. We prepared 60%, 90%, and 100% design submittals, prepared construction cost estimates for all materials, and provided a design and construction schedule, site preparation and revetment plans, and construction support in the form of bid and contract closeout.
