Bids were opened by the Vigo County Commissioners on the replacement cost for the heating/air conditioning system on the oldest section of the Vigo County Security Center.
Bids ranged from $223,000 to $259.000.
B&S Plumbing & Heating Inc. had the lowest bid.
The Vigo County Council in June appropriated $300,000 to repair the air-handling system.
If the current system should fail, possibly 130 inmates would have to be relocated.
Commissioners took the bids under advisement pending a legal review.
