Construction Law/prolongation Cost


What is Prolongation Cost?

Dear Faheem,

Your question is general and does not show the specific scenario for prolongation cost.As per my understanding, once an extension of time has been awarded, the intention of most construction contracts is for the contractor to be reimbursed for the additional costs which have resulted from the employer-responsible delays. Basically, this involves a comparison between the contractor’s actual costs incurred and what the contractor’s costs would have been, had there been no delay occurred.

It is very important to keep in mind that compensation for prolongation should not be paid for anything other than work actually done, time actually taken up or loss and/or expenses actually suffered by the Contractor. In other words, the compensation for prolongation caused other than by variations is based on the actual additional cost incurred by the Contractor. The main objective is to put the Contractor in the same financial position it would have been if the Employer Risk Event had not occurred.

Hope it will help you.
