Selection of Contractor Using Analytical Hierarchy Process - A Review

Abstract

More or less there are few contractor selection methods currently in existence condemned as incomplete and biased, and lacking consideration in terms of the contractor’s ability to achieve simultaneously, time, cost, quality and safety standards. This paper outlines an alternative contractor selection prototype called the analytical hierarchy process (AHP), which will help construction clients to identify contractors with the best potential to deliver satisfactory outcomes in final contractor selection process which is not based simply on the lowest bid. A hierarchical structure is assembled for the prequalification standards. By applying the AHP, the prequalification criteria can be prioritized and a descending order list of contractor can be made in order to select the best contractor to perform the project. Since each construction project is unique, final contractor selection through the AHP gives clients the flexibility to add or reduce the elements of a problem hierarchy regarding an individual project.
