Andersen Air Force Base, Guam
Under contract with the Air Force Center for Engineering and the Environment, Shaw remediated two dump sites along a 500-foot cliff overlooking the Philippine Sea at Andersen Air Force Base on the island of Guam.
During the World War II era, Air Force-derived waste was discarded along the top of the slope and pushed over a 1,200 foot slope with grades up to 80 percent.
Shaw’s own Unexploded Ordnance (UXO) remediation teams cleared an estimated 23 acre site of all Munitions and Explosives of Concern, which were then destroyed onsite via open-burn destruction activities.
The team also has removed waste such as contaminated soil, rubber tires, metallic scrap and airplane parts.
To contend with site geography, Shaw’s team constructed an estimated 5,000 linear feet of benches into the limestone bedrock using hydraulic hammers in order to access the waste located along the steep slopes. The team also used a skyline yarder, a piece of equipment typically used by logging industries in the Pacific Northwest, to lift the items from the bottom of the cliff to the top.
