Yes, Provisional Sum is an amount designated to the contigencies at time of Tendering whereas Prime Cost Sum means a sum designated to work to be executed by a nominated sub-contractor or for materials to be supplied by a supplier

Anthony,



If my equally hazy memory serves me correctly, a “Provisional Sum” is a sum that is provided for work or for costs that cannot be entirely foreseen, defined or detailed at the time of issuing the tender documents, whereas a “Prime Cost Sum” means a sum provided for work or services to be executed by a nominated sub-contractor or for materials or goods to be obtained from a nominated supplier.

Hope this helps,
