This project was a joint venture with WPC, Inc. General Construction's scope of work included widening the existing pier with a new 543 ft x 35 ft pier addition, partial demolition, breakwater extension, approach trestle addition, mooring dolphins, mooring camels, hydraulically operated power booms, mooring fittings, mechanical and electrical systems and a pier fender system. WPC, Inc. constructed a two-story office building on steel piles, an addition to an existing building, and a new storage facility.
General Construction Company was a subcontractor to Watts Constructors for the construction of an acoustics testing facility located at Bangor Subase on the Kitsap Peninsula in Washington. The facility was built on a floating pontoon the Navy purchased. Generals scope of work consisted of constructing the approach trestle, eight mooring dolphins for the pontoon, and mooring the pontoon with assistance from the Navy. A total of 20 trestle piles and 40 dolphin piles were driven, 4 precast and 2 cast in place trestle pile caps were installed, 25 channel beams for trestle deck were installed, 8 dolphin pile tops were formed and poured, and a mooring pontoon was constructed.
For this project 244 steel pipe piles were driven through 122 holes cut in the existing causeway deck. The falsework and side forms were installed below the causeway for new concrete bent caps at each cluster of four piles. Six existing causeway expansion joints were demolished and rebuilt to allow for greater movement during a seismic event. A new pipe trestle was made of steel beams and 609 pony bents and pipe supports.
A new T-pier with 200 lin ft of fixed berthing and a 120 ft floating finger pier were built to support transient Navy vessels and small crafts. The facility also includes a floating boathouse, to provide covered moorage for the Admiral's barge, and three smaller slips. Mechanical and electrical utilities were provided for all new structures along with relocation and installation of existing jib cranes and other vessel service equipment. Demolition of two existing timber piers and the existing fixed boathouse were included as part of the project scope.
General Construction dredged and disposed of 62,000 cu yd of material off the Ranier Marine Docking Facility. Wharf and trestle construction included 165, 24 in. steel piles filled with 1,200 cu yd of concrete to complete the foundation. Another 1,200 cu yd of concrete was placed for the reinforced pilecaps, dolphins, bulkhead, edge beam and curb.
General Construction Company partnered with BERGER/ABAM for this Design/Build project. The contract required demolition of an existing 650 ft timber pier and construction of a new replacement concrete pier and concrete mooring floats. The construction included 16 in. diameter concrete piles, poured in place caps, precast deck panels, and crane beams. In addition to the new pier, a custom 25-ton capacity 'Marine Travelift' boat hoist was installed.
This contract is for the replacement of Pier 23 in Tacoma, WA, and includes the demolition of 600 feet of timber pier and replacement with a new concrete pier. The new pier will consist of precast concrete piles, cast-in-place pilecaps, and precast decking. This project also requires environmental remediation to remove in-water sediment and slag.
This project included demolition of the existing pier. A new carrier pier was founded on 24 in. octagonal concrete and 24 to 36 in. coated steel piles. Steam, water and other services were run in utilidors along the outboard pier edges. New systems for ships' sewage disposal were constructed.
General Construction removed the timber fender system at Pier 7 in Bremerton. The fender was replaced with a contractor designed pre-stressed concrete fender pile system that was attached to the existing pier with built-up structural shapes. Rope guards, ladders and other miscellaneous items were included in the scope of work.
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.
