Remeasurement

Civil Engineering Procedure 7th Edition, published by the Institution of Civil Engineers in 2016, suggests that remeasurement (or occasionally re-measurement) is the:

…calculation of the actual quantities of work ordered on the contractors in order to certify the payment due to a contractor. Remeasurement is also known as measure-and-value’.

There is a subtle difference between the term remeasurement and the term admeasurement, in that remeasurement refers to the entire process of measuring again the quantities of work undertaken, whereas admeasurement refers only to the difference between the estimated quantity and the actual quantity.

Remeasurement contracts, measurement contracts or measure and value contracts may be necessary on projects where the type of works required can be described in reasonable detail when they are tendered, but the amount cannot. For example, excavation works where the quantity of excavation required is difficult to assess until after the works have begun.

Instead of giving a firm price, rates are provided in the contractor’s tender, either as part of the priced approximate bill of quantities, or within a schedule of rates. Then the actual quantities of work carried out are measured and the tendered rates applied to those quantities. The contractor is paid for the actual work they have done. As a result, the quantities paid for may vary from the original estimates.

See Measurement contract for more information.
