C.J. Mahan Construction Company appealed a decision regarding additional costs incurred due to a requirement to employ a sixth crew member for diving operations, which the Board found to be a constructive change to the contract.

Material Facts

  • C.J. Mahan Construction Company entered into a contract with the United States Army Corps of Engineers to remove a lock and dam on the Ohio River.
  • Mahan bid the contract based on a proposed five-person dive team, which was approved by the government.
  • The USACE later required Mahan to employ a sixth crew member when attempting to use a second working diver.
