Completion

2014
The intermodal Quincy Commuter Boat Terminal provided access to the commuter ferry and historic U.S.S. Salem museum.  The site consists of a bulkhead seawall and a reinforced concrete wharf.  In November 2011, a water main located behind the seawall along the ferry dock failed.  The top of the wall moved outward and the soil behind the wall subsided several feet.  SGH led a multi-disciplinary team to evaluate the seawalls and concrete wharf, recommended remedial work, and designed seawall and wharf stabilization measures.
