The resident engineer’s office records 151 • the records must clearly show what has been paid for (under interim certificates) as distinct from what has been measured. The foregoing can be catered for by showing, in the quantities calculation book, two columns as shown in Fig. 13.3. The first column shows the total volume for part of the works; the second shows an estimate of how much has so far been certified for payment. The measurement engineer will work from notebooks containing dimensioned sketches of the amount of work done measured by himself, or by assistant engineers and inspectors who send him notes. All these he will file, and armed with the quantities he calculates as a result, he checks the contractor’s monthly claim in detail, item by item. Where he thinks something has been mis-measured or over-claimed by the contractor he raises this with the agent – or more usually with the contractor’s quantity surveyor. Comparison of quantity measurements takes place to see where the difference might lie. If the difference is one of interpretation of how the quantity should be measured, the RE will Fig. 13.3.

152 Civil Engineering Project Management have to decide what is the correct interpretation. If the contractor wishes to argue the matter it becomes ‘a claim’, and is put in the Claims Pending file with all details attached. The RE may raise the dispute over interpretation with the engineer’s contracts department when he sends in the contractor’s application for checking. If the contracts department agree with the RE’s ruling, there is no further action to be taken; but if the department agrees with the contractor they may re-insert the contractor’s claimed amount or whatever the RE has advised would be the figure in that case. Measurement sheets are best filed in ‘lever-arch’ files, in order of the Bill Items. In the early stages of the job it may not be worthwhile attempting to make any exact calculation of the quantity of an item. In that case a rough sketch is drawn on the measurement sheet, showing how an estimate of the work done has been calculated. 13.7 The contractor’s interim payment applications The contractor’s monthly application for interim payment is usually set out as shown in Fig. 13.4. Initially only the items under which work has been measured need be listed, divided into bills. Later, when all the work listed on a page of the bill of quantities has been completed, the page total only need be quoted in the bill summary. Where work is incomplete and only an estimate can be made of the work done, the RE may accept the contractor’s figures if they are reasonable. But where work is completed, the contractor’s final measurement of a quantity should check reasonably with the RE’s estimate. In such matters as excavation the RE should not require an unreasonable degree of accuracy, measurement to the nearest 1 m 3 is adequate. For minor differences between the contractor’s figures and the RE’s, a compromise figure may be agreed. Major differences should be looked into. To aid estimating the probable final cost of the works (see Section 14.9) it is best if extra items are put on a separate sheet or sheets, grouped for each separate bill of quantities, where possible. Extra items not authorized by a previously issued variation order (VO) must be checked by the RE. If he agrees them he must send a draft VO to the engineer to cover them. If he thinks an extra is invalid, or the rate or quantity is wrong, he should discuss this with the contractor, and may decide to delete the item, accept it, or substitute a rate or quantity he considers fair. He draws the engineer’s attention to his decision when forwarding the contractor’s payment application to him. If the contractor continues to dispute the item after the engineer’s decision on it, the matter becomes a claim, is given a number and put on the Claims Pending file for further consideration. It is preferable for each VO to cover one instruction only. However, one VO can be made to cover a series of related instructions, provided the instructions covered are itemized. A typical style of VO is shown in Fig. 13.5.
