Construction changes at the Augusta Regional Airport’s new general aviation terminal, which is now 5 percent over budget, are costing an additional $149,000.
The Augusta Aviation Commission approved the project’s ninth change order Thursday. Executive Director Gary LeTellier said the airport was liable for the items on the latest contract modification.
The original contract, awarded to Choate Construction Co. on June 30, 2011, was for $5.05 million. Previous contract modifications totaled $222,748.
The latest change order includes $46,538 for construction delays, which resulted when contractors arrived on site to begin work and found the existing airport terminal was not cleared for demolition. Airport administrators said they were waiting on temporary trailers to move into, which caused the delay.
Other items on the contract modification were for costs associated with material testing, soil replacement and interior building finishes such as paint and cabinets.
An additional change order of $50,000 for poured concrete is still being negotiated with the contractor. The airport said the concrete quality did not meet specifications.
While the concrete claim is disputed, a retainer fee totaling about $200,000 is being withheld.
