National Salvage & Service Corp. of Bloomington, Ind., won a $6.4 million state contract to tear down abandoned buildings at the former Kings Park psychiatric hospital in Kings, NY.

National Salvage & Service Corp., is expected to employ about 65 people to demolish 15 buildings and other structures at the 500-acre hospital site.

National Salvage beat 19 other firms with a bid far below the $15 million allocated by the state for the demolition.

Demolition is expected to begin in May and should be finished by November 2013, state officials said. Among the buildings to be torn down are maintenance and power facilities, a boathouse, a dairy barn and the morgue.
