A provisional sum is an allowance (or best guess), usually estimated by a cost consultant, that is inserted into tender documents for a specific element of the works that is not yet defined in enough detail for tenderers to accurately price.

A provisional sum can be categorised as ‘defined’ or ‘undefined’.

Undefined provisional sums are less well described as they refer to work which is not completely designed. As such, the contractor cannot be expected to make allowance for them in their programming, planning and pricing preliminaries. This means the contractor may be entitled to an extension of time and/or additional payments when the actual works are undertaken.

An example of an undefined provisional sum might be when work is required below an existing structure, but the ground conditions, and so the extent of work required, cannot be determined until it is demolished and the ground opened up. This can often be the case with a site of potential archaeological significance.

With undefined provisional sums, the client tends to assume the relevant price and planning risks and grants the contractor such allowances accordingly.
