When the agency that awarded the contract or GTA determines it to be advantageous to the state, it may authorize revisions to a contract specification, including any cost adjustment associated with any such revision, as part of contract administration. If an increase in cost results in the total contract value being more than the agency's delegation, then the agency shall obtain prior written approval from GTA, regardless of what agency initially awarded the contract.
