LAKE CHARLES — The Chennault International Airport Authority has awarded a contract for construction of the Hangar H project.

The hangar should be completed by June 2014 and is expected to generate about 500 permanent jobs, airport Executive Director Randy Robb said.

The contract was awarded to Alfred Palma LLC for about $10.3 million.

The new hangar, with 112,000 square feet of hangar space and 6,000 square feet of office space, will support the growth of Aeroframe Services and Northrop Grumman, Robb said.

Its overall development cost is estimated at $21 million.

“Chennault is growing and moving forward just as fast as we can build,” he said. There is room at Chennault to add another hangar the size of Hangar H, he said. The hangar is made for four planes.

Robb said Chennault will pay about $4 million; the state will pay $3.1 million; Louisiana Economic Development will pay $14 million from the Community Development Block grant program; and $400,000 will come from state Department of Transportation and Development.

Construction is expected to begin in May.
