Aecom Technology Corp. has received a contract to resume program management of construction projects planned by the Libyan government’s Housing and Infrastructure Board that were suspended during that country’s 2011 revolution.

The downtown L.A. construction and engineering firm announced Friday that the contract will be worth at least $209 million over a 25-month period. The company will manage a housing and infrastructure development program now valued at more than $36 billion. Aecom ran the housing and infrastructure program from 2007 until it was suspended in 2011 during the uprising that toppled the regime of Muammar Gaddafi.

Also, Aecom said Monday that its joint venture in the United Kingdom was awarded a contract with Thames Water, worth nearly $286 million, to rebuild a London sewage facility, the Deephams Sewage Treatment Works.

Aecom and its joint venture partner, Murphy and Kier, plan to help Deephams meet new environment agency sewage treatment standards without disrupting the facility’s operations.

Aecom shares on Monday closed down 29 cents, or 1 percent, to $28.75 on the New York Stock Exchange/
