How & by whom Prime Cost sums and provisional sums are included In the building contract, prime cost sum is a 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. In the building construction some of the special work must be do the special contractors. So client appointed the nominated sub contractors. And some materials also supply to the site by nominated suppliers. Those are the reasons the prime cost sum include the building contract by consultant. Prime cost sums are deemed to be exclusive of the general contractor’s profit. Provision is made in bills of quantities and specifications for a separate addition which is normally calculated as a percentage of the p.c. sum, the tendered stating the percentage that he requires. In the event of the Employer paying a sub-contractor direct for any reason, the general contractor is still entitled to the profit addition, as this is management fee for arranging, organizing and taking responsibility for the sub-contract or for arranging and checking the supply of goods and materials.
When there are bills of quantities, ‘general attendances’ on all nominated are given together in one item; individual items are given for ‘special attendances’ on each sub-contractor as required. The former are defined in the SMM7. Clause A 42 of SMM defined the general attendance and special attendances are defined under Clause A 51 of the SMM, include such facilities unloading and positioning heavy and large items, storage accommodation and welfare facilities provided by the contractor for his own use. Sometimes contractors show prices of attendance items as % of the p.c sums in the same way s the profit items. In such cases, the amounts should still be treated as lump sums and the surveyor would be wise to obtain the contractor’s agreement to this and to the deletion of the % rates, prior to the signing of the contract. 2.3 Adjust cost sum and provisional sum and prepare a summary to be included in interim valuation and final accounts, using the following data.
