If the contractor is employed at the inception of the construction project, so which they can contribute their support to the improvement of the design from the commencement, they can be employed through a two (2) phase procedure. In the initial phase, the contractor is carefully chosen on the basis of a fee, preliminaries, profit and overhead. Then they work with the design team, who might be hired either by the employer/ client or by the contractor at this phase to improve the design, on the base of that a fixed amount is negotiated for the second phase; construction, when the design team may substitute a new contract for an old one to the main contractor if the main contractor does not already hire them.
