Under the $62m contract modification, the company will provide base operating support services (BOSS) at the US Navy installation in the British Indian Ocean Territory.
Awarded by the Naval Facilities Engineering Command (NAVFAC) Pacific, the contract is the first in a series of possible seven option years on a previously awarded contract to KBRwyle.
On 5 October 2017, a $515m fixed price with award fee contract was given to KBR Diego Garcia, which is operating under KBRwyle.
If all option years are exercised, work on the project is expected to be carried out over eight years.
KBR president and CEO Stuart Bradie said: “As one of the few companies that has the expertise to support the US military in such remote locations, it’s our honour to continue serving the US Navy’s men and women in Diego Garcia.
“This work further solidifies our position as a trusted base operating support provider to the US military.”
The range of services to be provided by the company includes facilities management, IT, supply, utilities, administration and public safety.
The company will also be responsible to deliver services such as morale, welfare and recreation support, and port and air operations.
KBRwyle will use its expertise in delivering services at remote locations to support multiple US Navy and Army bases worldwide and a US base in Africa, as well as take care of its sailors.
Established in October 1977, NSF Diego Garcia provides services for the vessels of the US Navy, British, MSC and Allied forces transiting through Diego Garcia.
