The valuation of variation is a critical aspect in the post contract stage. The Contractor has to carry out the works according to issued variation order or on the instructions given by the Engineer even without having the approval. The Contractor might be paid a percentage on the submitted price until cost proposal is certified by the Engineer. The submission and certification process is delayed on most of the projects and this will lead the Contractor to suffer losses from the project.
