34 • September 2016 www.concreteproducts.com Applying its modular structure fabrication competencies plus branded refractory concrete fire wall system, Oldcastle Precast has completed a turnkey infrastructure project at the Boeing Co. Main High-Voltage Substation in West Jordan, Utah. A new building accommodates battery power to a redundant 138-12.47 kV, 20MVA, 3-phase, three wire grounded 60-Hz sub - station for the company's West Jordan manufacturing facility. Oldcastle Precast's project scope included the design, construc- tion, outfitting, and installation of the 350-sq.-ft. enclosure with redundant (A&B;) 125VDC battery, plus TruFire Walls for fire and explosion protection of the redundant 12.47kV Plant utility power source. Work included fabricating a high-seismic and ballistic proof, drop-in battery building that has fire rated walls; capacity to regulate and monitor inside environment up to 77°; capabili- ties to contain acid spills; resistance to high salt "air" spray; and, ability to withstand hurricane force winds. The fully outfitted building has a raised floor, defined conduit and water pop-up location, plus a 125VDC uninterruptable station service power supply and Dual 125VDC, 400Amp-Hour DC Battery in 2-Step Seismic Rack. Experienced Oldcastle Precast teams installed and tested the components prior to dispatch. Outfitting the structure off-site kept the complex engineering work out of the critical path and away from Boeing operations. "The best and least expensive option for Boeing's LIVE substation was to drop-in a fully assembled concrete enclosure," says engineer Ray Glenn of Kirkland, Wash.-based substation design specialist Casne Engineering Inc. "The safety procedures for getting nonelectrical [crews] working around high voltage are daunting. The Oldcastle Precast battery building was not only a high quality built, walk-in, enclosure, but it also reduced the construction schedule and improved safety by not having non-qualified personnel inside a 'LIVE' substa- tion environment."
