ABSTRACT
Where work in an existing building is concerned it has been assumed that the building is vacated and that in all cases there is reasonable access and adequate storage space. Should this not be the case, and if any abnormal circumstances have to be taken into account, an allowance can be made either by a lump sum addition or by suitably modifying the percentage factor for overheads and profit. All rates include an allowance of 7½% for profit and 5½% for overheads.
