Construction industry is complex with challenging sequences and the involvement of several stakeholders. Subcontractors are one of the most important stakeholders in the construction industry since they actually implement more than ninety percent of the overall construction process. This paper intends to explore and prioritize the subcontractor selection criteria in both prequalification and bidding stages in Cambodia building construction. After identifying the important selection criteria by using Delphi method, the Analytical Hierarchy Process (AHP) was then used for the pairwise comparison of 28 specified sub-criteria under 7 main criteria in the prequalification stage and 10 identified sub-criteria with 4 main criteria for the bid evaluation stage. The selection criteria were intensively considered by 94 construction experts who were registered in Cambodia Constructor Association (CCA). Furthermore, the outcomes were analyzed through AHP relied on a questionnaire survey to achieve the participants' consensus on priority weights as well as their ranking of subcontractor selection criteria, respectively. Therefore, this research generated a set of guidelines to help practitioners enhance the quality of project delivery by using sufficient criteria as an input to the construction company in Phnom Penh, Cambodia concerning the strategy of subcontractor selection.
