Abstract
The construction industry has a complex supply chain, where subcontractors play a significant role in the success of construction projects. Subcontractors are responsible for delivering specialized services, such as electrical, plumbing, and HVAC systems, among others, which are critical for the successful completion of construction projects. Therefore, understanding the factors that affect the performance of subcontractors in the construction industry is essential for improving project outcomes. This study examines the factors that influence the performance of subcontractors in the construction industry. Using Literature reviews, the study identifies several factors that impact subcontractor performance, including project management, communication, collaboration, financial stability, and trust. The meta-analysis shows that effective management of these factors can lead to improved subcontractor performance, which is critical for the success of construction projects. The study provides a comprehensive understanding of the key factors affecting subcontractor performance and offers insights to assist project managers in improving their subcontractor management strategies. The findings from this study contribute to the existing literature on subcontractor performance in the construction industry and have practical implications for project management practices.
