The Port of San Francisco has selected CH2M and Arcadis to lead the design and engineering for the 10-year seawall resiliency project.
Arcadis will lead risk analysis, coastal engineering and modelling of the US$40 million project, while CH2M will provide marine and structural engineering services for the seawall and other structures.
The aim of the project is to fortify 5.6 kilometres of a century-old sea wall protecting the waterfront from Fisherman's Wharf to Mission Creek near AT&T Park, home of the San Francisco Giants baseball team.
Arcadis's City Executive Peter Wijsman said improvements included earthquake protection enhancements and flood risks caused by climate change.
The seawall supports historic piers, wharves and buildings, including the Ferry Building. It underpins the Embarcadero Promenade, which welcomes millions of people each year and provides flood protection to San Francisco's Financial District and other neighbourhoods.
The seawall also serves as a critical emergency response and recovery area, and it supports multiple municipal transportation systems and utility networks.
