ConDig (31-Aug-17).  A joint venture partnership between Granite Construction Inc and Japanese construction company Obayashi Corp has won a $165 million design-build contract for a Marine Corps base in Guam.

Under the deal with the Naval Facilities Engineering Command Pacific, the joint venture will prepare a 400-acre site for future construction of operational, administrative and bachelor housing structures for the new Marine Corps base, which sits within the Naval Computer and Telecommunications Site Finegayan boundary.

It will also be responsible for the demolition of existing structures, utility relocation, new utilities, roads and other infrastructure such as fencing, sidewalks, signage and striping. The deal will also feature clearing the site of unexploded ordnance and munitions of explosive concern.

Construction will be carried out using green waste and storm water management, mitigation of historic properties, and conservation measures for threatened and endangered species, according to Granite.

Work on the project is already underway and is slated for completion by 2020.

Watsonville, California-based Granite also noted that its portion of the contract is 55% and the total contract award of $165 million will be booked into its backlog in the third quarter of this year.

The base will be built to accommodate nearly 4,000 Marines who will transfer to Guam from Okinawa, Japan, in the coming years.

The Japanese government will fund the project as part an international agreement between Japan and the US.

Earlier this week, a subsidiary of civil, building and specialty construction company Tutor Perini Corp secured a $78 million design and build contract for a live-fire training range complex at a US naval base in Guam.

Guam is a US island territory in Micronesia, in the Western Pacific.
