A newly released audit says the largest U.S. contractor working to stabilize Haiti after the 2010 earthquake is “not on track” to complete its assignments on schedule, has a weak monitoring system and is not adequately involving community members.

Washington D.C.-based Chemonics won a $53 million, 18-month contract from USAID in 2011 to help Haiti strengthen its economy and public institutions. USAID’s Office of Inspector General released a report Monday that found Chemonics had a series of slips, including using arbitrary ways of evaluating its work, failing to hire local workers, and going ahead with potentially damaging environmental projects before they were approved.

“This report touches on a lot of issues we’ve seen with the overall reconstruction effort,” said Jake Johnston, a researcher at the Washington D.C.-based Center for Economic and Policy Research who studies U.S. spending in Haiti. “There’s a lack of transparency and the work is often poorly planned and poorly executed.”

Chemonics did not have an immediate comment, but a spokeswoman said it was preparing a response. USAID’s Office of Transition Initiatives, which manages the Chemonics contracts, said in a written response to the audit that it agrees with all of the recommendations and that changes are under way to resolve the issues.

“It should be noted that it is challenging to attribute direct results in complex and fluid stabilization environments, and it is often the absence of destabilizing events that demonstrates stability in these historically volatile areas,” USAID directors Robert Jenkins and Steve Olive said in a joint response.
