In Evans Construction Co. v. State, 44 Ill. Ct. Cl. 112 (1988), a contractor sought compensation for additional work that was performed outside the scope of the written contract in connection with the rehabilitation of an underground parking garage. The project engineers of the State gave oral and written directives to the claimant for the additional work to be performed. The Court held that while the disposition seemed harsh, the Court must give deference to the rule of law fashioned to protect the public monies and those expenditures not specifically approved as required by the contract were not recoverable.
