 Terracon provided geotechnical and construction materials engineering to the Portsmouth Naval shipyard reconstruction

Terracon provided geotechnical engineering and construction materials engineering and testing services on a full-time basis for the reconstruction of a dry dock at Portsmouth Naval Shipyard in Kittery, Maine. The $21 million project included the replacement of the caisson gate, sill walls, and sill floor at Portsmouth Naval Shipyard's 105-year old dry dock facility. The contract required the demolition of the existing granite blocks and concrete bedding and phased demolition of existing sill structures, including caisson sill armoring. Terracon worked with the client and NAVFAC's engineering team to provide geotechnical monitoring of the dry dock sill and wing walls and surrounding structures during construction.
