Lump Sum Contract

Definition

A lump sum contract (also called a fixed price contract) is one where the contractor agrees to complete a defined scope of work for a fixed sum of money. Unless agreed variations are instructed, the contractor bears the risk of any cost overruns resulting from their own errors or underestimation.

In construction tendering, this means...

Lump sum contracts are the most common form of contract for commercial building projects in the UK. They give clients certainty of cost, but only if the scope is clearly and completely defined at tender. Ambiguous or incomplete scope at tender stage in a lump sum contract is a reliable recipe for disputes and unwanted variations.
