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 furnished and installed this system, which supplies hydraulics to airplanes during assembly. The primary components include a 1,500 gallon stainless steel storage tank and 6,600 feet of stainless steel pipe. The piping installation required more than 850 welded connections, many in difficult, awkward, and tight positions.
General Construction was given the opportunity to help modernize and make a airplane manufacturing facility in Everett more environmentally friendly by bringing more natural light into the building. This project included the installation of 25ft x 27ft skylights that are 14ft tall.
General Construction was responsible for installing eight new aircraft painting platforms (stacker cranes) fabricated by OIW. Scope of work included installation of approximately 3,500 lin ft of crane rail, six low bay and two high bay stacker cranes including bridges, trolleys, masts, and platforms. In addition to the structural components, GCC was also responsible for installation of all mechanical, power and controls wiring, as well as full functional test and commissioning of the cranes.
This project included installing a new 3,000 CFM air compressor with two new mist eliminator prefilters, installing a new refrigerated air dryer, and connecting the compressed air piping, cooling water piping, and circulating pumps. Also included were new electrical switchgear installation and power and control wiring.
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.
