The North Ramp Parking project completed at Andersen AFB, Guam was built in support of the MV-22 Aircraft being brought to Guam as part of the overall U.S. Marine Corp relocation from Okinawa, Japan.

The project has received an “Outstanding” performance evaluation from NAVFAC. Demolition included the removal of existing pavements, perimeter CMU fencing, and miscellaneous structures, as well as clearing and grubbing over a number of acres followed demolition. Earthwork included the importation and placement of over 500,000 tons of fill material to bring the site to grade. A 19,000-cubic-yard Gabion retaining wall structure was constructed, allowing the fill work to encroach into an existing sinkhole. Extensive planning and coordination with Guam EPA took place prior to the start of this earthwork activity located in an environmentally sensitive location. PCC pavements include nine-inch-thick and 17-inch-thick sections, both reinforced and unreinforced, with a total quantity placed of 38,000 cubic yards. AC Pavements included 31,000 square yards at six inches thick, 1,900 square yards at four inches thick, and 5,300 square yards at two inches thick. There were a total of 45 storm drain inlets and manholes, and the storm drain pipes ranged in size from 24 inches diameter to 72 inches diameter.

The storm drain system included a CIP concrete oil water separator and sand filter ponding basin. At the start of the project, all existing electrical and sensitive communication lines located within the apron footprint were rerouted. Other site utilities included water, sewer with OWS, fire hydrant lines, airfield lighting, high mast lighting, and emergency fuel shut-off lines. Sediment and erosion control measures were strictly implemented and BCC’s ECATTS qualified Environmental Manager worked closely with NAVFAC and Andersen AFB Environmental staff in developing an Environmental Management Plan that incorporates BMPs that prevented any adverse environmental impacts as a result of construction operations. The HACCP plan that was developed and implemented met all expectations. This project included the handling and disposal of asbestos contaminated soil and asbestos containing pipes.
