The Spokane Airport Board has received bids for two upcoming projects at Spokane International Airport worth a combined estimated $773,000, and expects to award contracts for them soon.

For a project to upgrade some of the main terminal building's chillers, Shannon Industrial Contractors Inc., of Coeur d'Alene, submitted the apparent low bid of $345,000. Meanwhile, Aztech Electric Inc., of Spokane, submitted an apparent low bid of $428,000 for a project to install new conduit and wiring for the lighting system in the airport's five-floor parking garage.

SIA spokesman Todd Woodard says both projects will be done this summer, and neither should disrupt service to airport customers.

In the chiller replacement project, Shannon Industrial Contractors is expected to replace two 80-ton ventilation chillers with a 160-ton chiller. The current equipment is aging, and the new chiller will be more efficient, Woodard says. It will serve the A and B concourses, as well as some second-floor administrative space. The work is to be done in the ceiling, so it won't affect passengers at the airport, he says. Altogether, the main building has five chillers, Woodard says.

In the parking garage project, Aztech Electric will install new conduit and wiring for new light fixtures to be installed separately in the garage.
