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 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.
General Construction Company was selected to maintenance dredge the Day Island Yacht Harbor Marina. Dredging included about 6000 cy of material from the marina. We also installed new galvanized steel pipe guide piles for the new dock sections as well as new ACZA treated wood pilings as reinforcement for a nearby bulkhead.
PM Reality (agent for City of Alameda) contracted General Construction for this maintenance dredging job. General's own DB Oakland and Dump barge, using a 16 CY bucket, performed the dredging. Dredged material was passed through a screen to remove any material prior to sending the barge off for aquatic disposal at the designated dump site.
For this fast-track environmental and navigational dredging project, General remediated contaminated sediment and also deepened Sinclair Inlet for a new carrier pier. We dredged an underwater disposal pit, then placed 510,000 cu yd of contaminated material in it before capping it with clean sand. We also dredged 675,000 cu yd of clean sediment which was placed in in the deep water dispoasl site. Two environmental buckets, 24 cu yd and 27 cu yd, three split hull dump barges, differential GPS, and an electronic tide gauge were utilized to complete the work.
