A Provisional Sum is an amount of allowance money at the present time but likely to be changed that is tentatively agreed for the work to be performed. The Provisional Sum may be included in the contract as a specific contingency for the execution of work or the supply of materials or services which may be used in whole or in part or not at all based on the contract terms and conditions. The Provisional Sum is changed when the additional information is available, or work definition is more clearly defined.
