ABSTRACT
Prices should be applied to the total floor area of all storeys of the building under consideration. The area should be measured between the external walls without deduction for internal walls and staircases/lift shafts, that is, Gross Internal Area (GIA). Although prices are reviewed in the light of recent tenders it has only been possible to provide a range of prices for each building type. This should serve to emphasize that these can only be average prices for typical requirements and that such prices can vary widely depending on variations in size, location, phasing, specification, site conditions, procurement route, programme, market conditions and net to gross area efficiencies. The prices do not include for incidental builder's work nor for profit and attendance by a main contractor where the work is executed as a subcontract: they do however include for preliminaries, profit and overheads for the services contractor.
