Guys,

Can anyone refresh my memory? What is the difference between a Provisional Sum and a PC Sum?

I used to know the answer but the passage of time has played havoc with my memory.

I don’t have a contractual problem, just a realisation that I don’t know something now that I did know before.

Cheers.

    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.

    [Source: - not my questionable memory, but taken from Hudson’s 10th Edition]

    Hope this helps,

    Stuart

    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
