Measurement and bills of quantities 189 and/or materials to be supplied by the nominated sub-contractor. The sum entered by the engineer is that which he estimates will cover the sub-contractor’s charges; the actual charge made by the sub-contractor being refunded to the main contractor. Two additional items are added which tenderers can price. One consists of a lump sum to cover the general facilities the contractor is to provide for the sub-contractor; the other, expressed as a percentage of the prime cost, is to cover all the contractor’s other charges and his profit. The general facilities as defined in CESMM are deemed to cover – access; use of scaffolding, hoists, contractor’s messrooms and sanitation; space for any office and storage the sub-contractor sets up; together with light and water. If more facilities than this are required, the CESMM requires this to be expressly stated. Such extra facilities are often required, such as provision of power, labouring assistance, use of crane, etc., and these have to be defined. If, however, the sub-contractor supplies materials only, the lump sum is deemed to include the contractor’s unloading, storing and hoisting of materials delivered. One practice to be avoided is to permit a sub-contractor chosen by the contractor to submit his quotation only to the contractor. This could lead to the sub-contractor including in his quotation for doing some work that is paid for elsewhere in the contractor’s contract, resulting in double payment to the contractor. A preferable approach is for the engineer to call for quotations from sub-contractors to be submitted to him. 15.10 The preliminaries bill and method-related items A preliminaries bill lists items which apply to the contract as a whole, such as insurance of works, offices for the resident engineer, provision of laboratory, surveying equipment, transport, telephone and tests on materials or the works. The units of measurement will be appropriate to the type of item, lump sum, or per week or month, or per number of tests, etc. Sometimes an item needs to be split into two parts, such as a lump sum for provision of the engineer’s site office, with a second item for its maintenance per week or month. Such items listed by the engineer in the bill must be supported by descriptions in the specification stating exactly what the contractor is to provide. See Fig. 15.1 which shows part of the first page of a preliminaries bill drawn up according to CESMM. Temporary works The engineer may list temporary works the contractor has to provide, such as access roads, a temporary sewage treatment plant and similar. The listing of such temporary works permits the contractor to put a price to them, which may be to his advantage. Insurance is costly, so that if a tenderer prices this
190 Civil Engineering Project Management Fig. 15.1. Typical example of the first page of a preliminaries bill, drawn up according to CESMM Class A requirements, and priced by tenderer item, he can be reimbursed his expenditure on it as soon as he shows evidence of obtaining it. He does not have to wait for its reimbursement as he would have to if he spread the cost over the constructional items. Also, a priced item for such as the site sewage treatment works to be provided by the contractor is of advantage to the employer, since payment for such works can be withheld if the plant is not as specified or does not work properly. However, the pricing of
