Terminal 115, Port of Seattle?-?Seattle, Wash.
This project included the demolition of select sections of an existing wharf including asphalt pavement, precast concrete deck panels, cast-in-place concrete pile caps, removal of precast, pre-stressed concrete piling (14 in. square and 16 in. octagonal), and removal of a concrete bulkhead supported on sheetpile. The demolished wharf sections were replaced with similar segments constructed with 24 in. octagonal piling. A new concrete bulkhead was constructed on the existing sheetpile. Other activities included removal and reinstallation of the 130-ton transfer spans (ramps) and installation of a new transfer span (furnished by the owner). The work was completed in two phases to accommodate terminal operations. Other work included upgrading the water system and providing new electrical service to the re-constructed wharf sections.
