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.
General Construction was a subcontractor to Tucci & Sons for this project that included the construction of a 250 lin ft concrete wharf at the Port of Tacoma. The wharf was founded on 24 in. pre-cast octagonal piles. Work included installation of steel sheet piling and steel batter piles for the bulkhead and installation of a fendering system. The fender system at another berth was also upgraded prior to a critical fish closure. This work occurred in an active shipping channel.
The 43-acre Terminal 30 Upgrade project included relocation of the Cruise Ship operation, and returning the terminal to its original function as a container terminal. General's contract was to strengthen the existing concrete wharf in preparation to receive new container cranes. The 1,545 LF dock was upgraded using 166 new concrete piles that support a new waterside crane rail beam. In addition a 1,417 LF sheet pile wall and concrete cap were constructed to support the landside crane rail beam. Approximately, 59,000 cubic yards of material was clam shell dredged to provide -50 feet MLLW throughout the berth.
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.
This project required construction of a steel intake pier 450 ft into an active drinking water reservoir. Our work included 500-tons of fabricated steel supported by 22 piles in four piers. The 175 ton, 50 x 100 ft pump platform was assembled in place before lowering 20 ft and driving piles. In completed form it has steel walls and floor, slide gates, a jib crane and 8 pumps manifold to twin 6 ft pipes back to the beach. The work required a trestle, sheet cell, sectional barges with a 165-ton crane and extensive silt curtains.
The project began with the relocation of approximately 1,000 sq ft of eelgrass. Then a 250ft long by 50 ft wide trench was dug. Serving as a foundation for the diffuser, three, 4 ft by 12 ft articulated concrete ballast mats were placed at in 55 ft of water in Puget Sound. The 620 ft. long, 54 inch HDPE outfall pipe was sealed at each end and pulled from the beach into the water. While it was floating, 23 concrete weights were attached. Each weight was over 15,000 pounds. After attaching the onshore end to its tie-in point, we used controlled submergence to sink the pipe into the trench and onto the mats. Finally the trench was backfilled and the beach was restored to its previous appearance.
The first phase consisted of the construction of a habitat area by building an underwater rock berm from elevation -50 ft MMLW to elevation -20 ft MMLW. The area behind the berm was backfilled with 84,000 cu yd of dredge spoils. The second phase required the dredging of 392,000 cu yd of material and placement of riprap slope protection. There were 43,000 cu yd of unsuitable material that was excavated and disposed of at a designated landfill.
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.
