U.S. Army Corps of Engineers (USACE), Performance Oriented Construction Activity (POCA) Contract (W912PL-16-D-0004)

Yuma, AZ

GCE was subcontracted to provide design and construction services for several task orders under this POCA Indefinite Delivery/Indefinite Quantity Contract, including:

  • Relocation of Oasis Landing Zone, 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.
  • Aquila Recovery Site and Access Road, YPG, Yuma, AZ. The Aquila Recovery Site included the design and construction of a solar powered Unmanned Aerial Vehicle landing recovery pad. This was a vital component of a worldwide project sponsored by Facebook to bring Internet access to people living in remote locations. GCE designed and constructed a 5-acre circular landing pad, an ABC access road, a parking area, and a truck turn-around area. The access road construction was particularly challenging due to existing soil conditions. The site design included strategic placement along a topographic high to facilitate site drainage to the new retention basins. Additionally, GCE prepared the APP, SWPPP, QCP, and EPP prior to construction. GCE worked closely with YPG personnel to ensure every detail of this unique project was addressed to ensure successful project completion.
  • Demolition of the Ajo Border Patrol Station, Why, AZ. GCE was subcontracted for the demolition and restoration of a U.S. Customs and Border Patrol Facility in Why, Arizona, on property leased from the U.S. Fish and Wildlife Service. The existing facility was no longer in use due to the construction of a state-of-the-art facility adjacent to the site. This facility consisted of two buildings, multiple shade structures, approximately 1.2 acres of asphalt and concrete surfacing, walls, fencing, lighting, and other support items. This facility was previously used as offices for agents and for the processing and holding of detainees, which required it to be designed and constructed as an essential structure based on International Building Code requirements. Essential structures are the strongest structures built and are made to serve as emergency shelters during earthquakes, hurricanes, and other emergencies.

GCE recycled numerous items from the site including electronic gates, light poles, HVAC equipment and shade structures to reduce the amount of landfilled material. GCE also provided minimal vegetation disturbance during construction activities to restore the site to a nearly native condition.

In total, GCE disposed of approximately 4,700 tons of building materials and completed the project in accordance with all project plans and to the satisfaction of the USACE, U.S. Customs and Border Protection and U.S. Fish and Wildlife Services. GCE was able to mobilize crew and equipment to this remote site for an extended period due to the benefits of owning its own equipment and the flexible nature of incumbent staff.

  • Building 2210 Parking Lot and Drainage Improvement, YPG, Yuma, AZ. Building 2210 was located in the path of stormwater flow, that caused Building 2210 to undergo flooding during storm events and over the years caused mold contamination. GCE prepared a topographic survey of the site, and with a thorough review of the hydrological study, regraded the site to redirect the stormwater around Building 2210. This was conducted by installing a new concrete valley gutter incorporated into the parking lot and constructing a series of detention basins that collected stormwater so that the general drainage pattern of the area continued to flow southeasterly. The parking lot was replaced with new asphalt concrete pavement, and a new reinforced concrete tank crossing was constructed.
