The DOD needed to transfer approximately 8,000 U.S. Marines from Okinawa, Japan, to Guam. The U.S. and Japan negotiated the transfers in a realignment of U.S. forces in the Asia–Pacific corridor. NAVFAC was charged with developing a master plan for acquiring land and constructing facilities for the transfers.
In 2006, the Joint Guam Program Office (JGPO) was established to carry out the plan and oversee the transfers. Under a contract with NAVFAC, WSP assumed management of the program for the JGPO.
WSP was given many key duties in preparing for the transfer of the Marines and their families to Guam, including:
- Environmental impact statement review and environmental program management.
- Master planning support, integrated master scheduling, and utility and infrastructure planning.
- Sustainability and smart-growth planning.
- Providing the technical expertise of environmental scientists, engineers and schedulers.
