Bids for construction of a new Butler County office building came in under budget Thursday.

The total of the various low bids for the four-level building is nearly $11.2 million while the sum of the highest bids falls below $13 million.

The project, which includes repairing the roofs of the government center and courthouse as well as replacing three air conditioning units on the government center roof, was projected to cost $14 million.

County Commissioner Bill McCarrier, board chairman, was happy the bids came in under budget.

“I’m very pleased with it,” McCarrier said.

The lowest of six bids for general contractor was Vendrick Construction of Brookfield, Ohio, with a base bid of $5.6 million and another $1.2 million in bid alternates, which include the repair work to the existing buildings.

The commissioners will discuss the bids at Monday’s meeting with possible contract approvals Wednesday.

The new building, which will be adjacent to the government center, will house county Human Services.

Under the current schedule, the government center annex would be done in August 2015.
