Examines the issue of acceleration in construction, where the contractor carries out an obligation in a shorter period than originally planned. Most standard forms of contract allow the contractor to complete the works before the completion date. If the employer does not wish to take possession of the works early, the contract terms must be amended to take this into account. Some forms also give the contract administrator power to order acceleration to achieve the completion date if the delay is the contractor's fault. If completion by a particular date or time is not an obligation under the contract then the contractor will not be able to make a claim for the cost of acceleration measures. Any acceleration agreement needs to establish clearly whether the liquidated damages provisions apply if the revised dates are not met so that the courts can deal relatively quickly and easily.
