Definition

The amount stated in the building contract as payable for the agreed work, subject to the contract's adjustment rules.

Why it matters

It becomes the commercial baseline for valuations, variations and the final account.

Example in practice

The signed contract records the accepted tender total as the contract sum before later adjustments.
