The contract sum forms the financial cornerstone of a construction contract. It constitutes the amount payable to the contractor for the execution of the agreed works, including materials and any ancillary costs incorporated in the sum.

In practice, the contract sum governs the payment obligation, the settlement of additional and reduced work, and the basis for any indexation or price adjustments. In disputes concerning the scope of the works or liability for additional costs, the contract sum plays a central role in the assessment of the claim.
