Caddell Construction Co. has received its 26th contract with the U.S. State Department after being awarded the design and build contract for the new U.S. Embassy in Sri Lanka.

The Montgomery-based firm will be developing the 6-acre site in Colombo, Sri Lanka. The project will include a new office building, U.S. Marine residence, compound access building and a warehouse.

Also included in the development will be an entrance and arrival plaza, paved terraces, landscapes gardens, roadways and unique interior architectural finishes.

The contract, which is set for a duration of 48 months, is worth $155,941,000 and was awarded by the U.S. Department of State’s Bureau of Overseas Buildings Operations. Since 2000, Caddell’s contracts with the U.S. State Department have amounted to a total of $2.9 billion.

In 2011, Caddell was awarded the contract to develop the embassy in Ashgabat, Turkmenistan. BL Harbert International, a construction firm based in Birmingham, has also landed several high-profile embassy contracts in recent years, including ones in Zimbabwe, Kosovo and Jordan.
