Optimising Project Cost Control Practices for Enhanced Time Efficiency and Quality Delivery in Nigeria’s Construction Industry

Nigeria's construction industry grapples with soaring costs, missed deadlines, and poor quality—rooted in ineffective cost-control practices. This study examines the critical role of effective cost-control practices in achieving timely and high-quality project delivery in Nigeria’s construction industry. It addresses challenges such as budget overruns, schedule delays, and quality compromises linked to inadequate cost management practices. The study aims to identify actionable strategies to optimise cost control, focusing on enhancing time efficiency and quality delivery. A qualitative research design was adopted, using semi-structured interviews and thematic analysis to explore stakeholder perspectives on cost management practices. Findings highlight that integrating technology, conducting regular cost variance analyses, and providing targeted training for project managers significantly improve project outcomes. The study recommends leveraging advanced digital tools, such as artificial intelligence and machine learning, to optimise cost control practices and ensure sustainability in project delivery. Future research should investigate sector-specific challenges and regional variations to develop tailored strategies for improving cost management practices in Nigeria’s construction industry. These insights contribute to sustainable growth, efficiency, and improved project performance.
