Abstract : Contractor selection is a critical determinant of success in construction projects, directly influencing cost, schedule, and quality outcomes. Despite its importance, existing evaluation methods often lack objectivity, particularly in emerging markets like Egypt. This study proposes a standardized framework for contractor assessment using Key Performance Indicators (KPIs) during both prequalification and project execution phases. Through a systematic literature review (2015–2025), we identify 12 globally recognized KPIs and validate their relevance to the Egyptian context via expert surveys (N=200). A pilot case study of two social housing projects demonstrates the framework’s applicability, ranking contractors based on cost deviation, time adherence, client satisfaction, and defect rates. Results indicate that Contractor A outperformed Contractor B in 5 of 6 KPIs. The study contributes a data driven methodology to enhance decision making in contractor selection, aligning Egypt’s construction sector with international best practices.
