Yuma Proving Ground (YPG), Yuma, AZ
GCE was subcontracted to relocate and rebuild the Oasis Landing Zone Test Site and to improve the vehicle staging area and aircraft landing and refueling area. This project site consisted of a brown-out research and development area for use in helicopter testing operations. The project included the design and construction of an access road, test lanes, aircraft landing pad and all associated drainage features including drainage swales and on-site retention basins. The project also included the relocation of storage buildings, placement of power poles, and placement of military targets. GCE prepared all pre-construction plans: Stormwater Pollution Prevention Plan (SWPPP), Quality Control Plan(QCP), and Environmental Protection Plan (EPP). Construction included clearing and grubbing native vegetation and impediments from a 42-acre site, grading of the entire 42-acre site, construction of a storm water retention basin, construction of a 10,000 square foot aggregate base course (ABC) vehicle landing and refueling area, and the construction of a 40,000 square foot equipment staging area. The project was completed on time and within budget.
