Naval Facilities Engineering Command (NAVFAC) Marianas awarded a $7.2 million contract, Aug. 1, to Tikigaq Construction LLC of Alaska for a landfill closure capping system on Andersen Air Force Base (AAFB).

"This contract award is consistent with our strict adherence to environmental rules and regulations as we prepare to close the municipal solid waste landfill on Andersen Air Force Base," said NAVFAC Marianas Executive Officer Cmdr. Warren LeBeau. "It is an excellent example of our commitment to environmental stewardship and I'm pleased that we've identified a qualified small business partner for this significant initiative."

The work includes construction of a final cover system, passive landfill gas venting system, final cover slope protection drainage system, upgrades to the leachate system, and an all-weather access road with a lined drainage swale.

In addition, the scope of work includes installation of additional ground water monitoring wells as required by applicable laws and regulations, construction of a perimeter roadway, and construction of a perimeter subsurface drainage system to facilitate long-term maintenance and monitoring of the landfill cover system.

"The small business contractor, AAFB and NAVFAC Marianas will continue its great partnership with the Guam Environmental Protection Agency (EPA)," said NAVFAC Marianas Environmental Business Line Coordinator John Salas. "We will work collectively to ensure that the landfill closure project meets regulatory and industry design and construction standards."

This contract also includes an option to process and dispose of approximately 5,000 tons of scrap wood and green waste to a Guam EPA permitted solid waste management facility on Guam.

This is a firm-fixed-price contract and work is expected to be completed by February 2019.
