General Construction was responsible for the civil, concrete, structural steel, electrical, piping, and mechanical aspects of the project. Our work scope also entailed fire protection, insulation, HVAC, and instrumentation activities. Kvaener supplied and erected the new boiler. General Electric supplied and erected the turbine-generator.
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.
General Construction's task was to set and assemble the new switchgear and install the three new 15kV underground feeders from local utility metering to the new gear. From the new switchgear, eight new 15kV branch feeders had to be cut into the existing site distribution system. We then isolated and demolished the two existing primary feeders, reconfigured the 15kV taps to the building and connected the new system to the campus. General Construction was able to complete the shutdown work activities in five days, finishing the project ahead of schedule.
The shredder process line consisted of five major elements of equipment: infeed conveyor system, shredder machinery, ferrous metals separation equipment, non-ferrous materials separation equipment and debris separation machinery. All these elements were connected by a series of conveyors. Associated piping for water, pneumatics and hydraulics were also installed.
This project included removal of four existing batch-type homogenizing furnaces in scheduled phases. This was followed by the installation of a new precast 1,000 gallon underground cooling water return sump as well as an underground cooling water supply and drain piping. General Construction also built a new MCC foundations and installed billet conveyors, billet elevators, a walking beam cooler, gas piping and hydraulic/pneumatic systems.
Over a four year period, General Construction made improvements to upgrade and update cranes in this Renton factory. Over 100 crane rails were replaced and all crane rails were re-aligned. In the main assembly building, we removed, rebuilt and reinstalled crane bridges. Electrical systems were upgraded, including new safety interlocks and new bridge drives. All cranes serve active production areas so coordination and scheduling were critical to allow ongoing operations throughout this project.
This project included demolition and relocation of surplus tools and equipment, preparation of concrete floors, and removal of all mechanical piping and electrical branch circuits. Additionally, General Construction constructed multiple conference rooms, break areas and recycling centers. We installed 2,000 ft of new ductwork, 1,200 lin ft of copper piping, 232 dimmable Lutron light fixtures and power poles for 1,200 work stations.
This project upgraded the assembly facility's ability to withstand seismic forces. General Construction installed 2,000-tons of steel and 4,000 structural connections as high as 120 ft above ground. The entire project was accomplished with no interruption to production.
Due to deteriorating mechanical fittings in the heating system piping at an Everett assembly building, General Construction was given the task of refitting all the mechanical joints with new welded fittings. In order to complete this project within the small window of time available, the majority of the work was done over the 2006-2007 Holiday shutdown.
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.
