Features include a design-build concrete foundation poured underwater via tremie and precast boxes. The curved walls and flared floor of the chute were built in a 25 ft deep sheetpile coffercell. Stoplog guides, stoplogs and hoist, vertical and inclined gate guides and gates, and associated hydraulic and electrical controls were included in this project.
The E2 foundation, on the east end of the project, consists of a composite steel and concrete footing founded on 16 cast-in-steel shell piles driven 300 ft into the San Francisco Bay mud. The T1 foundation at the west end of the project is the foundation for the main suspension tower of the self anchored suspension bridge. It consists of 13 cast-in-place drilled hole piles which extend approximately 200 ft into the Alameda rock formation.
The 9,559-foot long Homer Hadley Bridge is part of the westbound I-90 bridge connecting Seattle and Bellevue. General Construction replaced the expansion joints that were cracked and deteriorating. This was a two-part process with the small joints being removed and replaced in May 2009 and the large joints being removed and replaced in July 2009.
Fan pumps supply pulp and a large volume of water to the forming section of a tissue machine. General Construction Company replaced the drives, cabling and motors for three 600 Hp fan pumps. To minimize downtime, we installed and tested new 10,000 lb. Allen Bradley variable frequency drives, new 2,300 volt cabling, tachometer feedbacks and ControlNet interfaces, all while the machine remained in operation on the original system.
General Construction installed new equipment, relocated existing equipment and replaced electric drives and controls. The electrical and instrument work included 16 new variable frequency drives, a safety interlock system on machine guards, photoeyes and solenoid valves.
When originally installed in 1980, this tissue machine was driven by DC motors to precisely control the speed of rolls and dryers. This project replaced all 42 motors, ranging from 5 Hp to 500 Hp, with AC motors fed by variable frequency drives. General's work included modifying motor bases, installing new motors, installing new solid state drives, and installing cabling and controls. Careful planning along with maximizing pre-shutdown preparation allowed this critical machine to get back online with minimum downtime.
General Construction installed 1,500 lin ft of cable tray, five miles of CLX cable, a 15kV switchgear, and 2,300V & 480V substations while mill operations continued normally. As new equipment was brought on line, existing antiquated equipment and feeders were removed from service without interruption to production.
