Interim monthly payments 199 paid the undisputed portion of his application within 28 days of submitting his account, and so might be entitled to claim interest on it for late payment (see Section 17.13). Dayworks charges (see Section 13.8) which have been checked and agreed by the resident engineer will also need to be included in the next interim certificate for payment, in so far as the contractor lists them in his account. The contractor’s account may, of course, list other dayworks charge sheets that have not been previously submitted to the resident engineer for checking. If there is time to check them, the resident engineer should include them for payment. Alternatively he might include a round sum ‘On account of unchecked daywork sheets submitted’, the sum being what he considers will at least be payable under them. However, he does not have to include any payment against a daywork account which provides insufficient information for him to check it. Similar problems of the need to make partial or ‘on account’ payments can arise in respect of claims submitted by the contractor which may be valid in principle but not sufficiently detailed to support the full claimed figure. Nothing need be certified in respect of a claim insufficiently detailed for it to receive any consideration (ICE conditions Clause 53) but amounts should be included for payment where sufficient details are provided to justify some payment. All such partial or ‘on account’ payments proposed by the resident engineer should be drawn to the attention of the engineer when the contractor’s account is forwarded to him. Where the resident engineer has agreed rates for extras with the contractor he should draft an appropriate variation order which he sends to the engineer for checking and issue. 16.4 Payment of lump sums, method related items and any adjustment item Unless there is some stipulation that a lump sum is to be paid in stages it only becomes payable when the whole of the work itemized under the lump sum is completed. However, fairness has to be applied when an item combines two operations and nothing is stipulated about staged payment. Occasionally a lump sum item reads: ‘Provide and set up engineer’s offices as specified and remove on completion’ so in theory the item is not payable until the end of the contract. At the tender negotiation stage, agreement should be reached as to how the sum is to be paid; but if the matter has been missed then it is up to the resident engineer to suggest how the item should be paid – perhaps 80 per cent on set-up; 20 per cent on removal, or some other proportion. Lump sums for such as insurance can be certified for payment as soon as the contractor produces evidence of insurance. Payment of method-related items (see Section 15.10) will depend on whether any special conditions have been laid down about them for staged payment,
200 Civil Engineering Project Management or if not, payment will be dependent on whether they are fixed or time-related. Fixed sums would be paid as mentioned above for ordinary lump sums, but problems can arise if the item description is imprecise. Thus if the contractor has added some method-related item for ‘scaffolding’ or ‘site transport’ as a fixed sum, it has to be further defined to relate to some specific scaffolding or specific transport; otherwise it is too vague to identify and cannot be paid until substantial completion. When method-related sums are time-related they are paid in monthly instalments, but the proportion paid will depend on when completion of the relevant task will be reached. Thus if an item is completed when substantial completion is achieved, and the programmed time for this is 18 months then, 1/18th payment is added at the end of each month. But if it then appears that substantial completion will not be reached until month 20, the total payment due at month 7 is 7/20ths. This is irrespective of whether the delay in completion is due to the contractor’s tardiness or to an authorized extension of the contract period. The reason for this approach is that method-related items are defined as covering ‘costs not to be considered as proportional to the quantities of the other items’. If an extension of the contract period has been granted, then any claim for extra payment on that account is a separate matter to be decided by the terms of the contract. The lump sum payable under a method-related item remains unaltered. An adjustment item in the form of a lump sum (see Section 15.11) is paid in the same proportion as the total payment due under other items less retention, bears to the total contract sum, less the adjustment item. If a percentage adjustment has been quoted, this is applied to the total amount payable under bill items and variations. In both cases the retention money is deducted after adding in the adjustment item. 16.5 Payment for materials on site The ICE conditions and similar permit payment to be made to cover part of the cost to the contractor of materials delivered to site but not yet built into the works. This can ease the contractor’s cash flow situation and is of advantage to the employer in encouraging early supply of materials so that unexpected shortages or late deliveries are less likely to hold up progress. In contracts that contain such a provision, tenderers can be expected to reduce their prices in anticipation of the expected financial benefit. Certifying payment for materials on site is left to the discretion of the engineer. Under ICE conditions Clause 60(2)(b) he has to certify such amounts (if any) as he may consider proper, not exceeding a percentage of the value as stated in the contract. In this he may need to act carefully because, even though material has been delivered to site, it might still remain the property of the supplier until he has been paid for it by the contractor. If the supplier falls
