In construction changes to the quantity, quality, order and even the nature of the work seem unavoidable. Construction contracts usually provide for changes to the work by giving the engineer the necessary powers to effect changes. However, changes to the work should be effected in such a way that they do not change the basic contractual relationships of the parties at time of tender. The engineer is therefore also equipped with the power, and is in fact compelled (when necessary to keep the original contractual relationships intact) to change the rates of the contractor in the contract so that the scale remains balanced between the parties. This article discusses a technique that can assist both engineer and contractor to quantify this principle.
