Abstract

The present condition of the construction industry imposes onerous responsibilities on contractors so they are very eager to subcontract some of their works. Subcontractors who directly handle a major portion of all construction activities have a highlighted role in the building industry, so suitable subcontractor selection has a direct effect on the productivity of construction operations. This paper aims to develop a comprehensive model for subcontractor selection based on the fuzzy preference selection index. The improvement of the proposed model lies in the fact that it has found a way to eliminate the weighting criteria phase in selecting the optimal subcontractor where weighting attributes is a challenging task. The consistency test is presented for investigating the accuracy of model results with the previous scientific work.

Highlights

New contracts (e.g. EPC, BOT, MC) have imposed various and onerous responsibilities on contractors, so they are very eager to subcontract some of their works
With respect to the calculations conducted by other approaches, fuzzy preference selection index (FPSI) method is very simple and decision makers can obtain the best and worst answer with minimum calculation
The authors developed a structured questionnaire for evaluating the proposed model. This questionnaire consists of four main questions as below: 1. Comprehensiveness: Does the FPSI method cover the required SC selection considerations?

Summary

Introduction

New contracts (e.g. EPC, BOT, MC) have imposed various and onerous responsibilities on contractors, so they are very eager to subcontract some of their works. Many general contractors (GCs) only act as construction management agents in construction projects and sub-contract a large volume of their work to subcontractors (SCs) (Shash 1998). Subcontractors were born for enduring some of GC’s responsibilities and for doing some professional activities such as concrete tasks, welding tasks, etc. It can be concluded that the selection of appropriate SCs has a direct influence on many branches in the organization and project management area. Because GCs will be evaluated in the qualifications for future works, the good performance of SCs can be affected on the rate of GC’s qualification.
