Abstract
The Nigerian construction industry continues to face persistent challenges such as poor material control, escalating costs, and frequent project delays. Although the Just-in-Time (JIT) management system has demonstrated significant success in manufacturing by minimizing waste and improving efficiency, its adoption in construction remains limited within the Nigerian context. This study investigates the major challenges hindering the effective implementation of JIT in construction projects across Edo and Delta States, Nigeria. A quantitative research approach was employed using structured questionnaires randomly distributed to 324 registered construction professionals. Out of these, 203 valid responses were collected, representing 62.65%, and were analysed. Descriptive statistics and exploratory factor analysis were used to identify and categorize implementation challenges. Sixteen key challenges were identified, with inadequate planning, financial constraints, and supply chain disruptions emerging as the most critical. Factor analysis grouped these challenges into three major components: Planning Factors, Financial Factors, and Delay Factors. The study revealed that inadequate planning, financial constraints, and supply chain disruptions are the main challenges hindering project execution in the study area. To improve JIT readiness, the study advocates for strengthened planning mechanisms, increased supplier collaboration, investment in logistics infrastructure, and targeted professional training. Future research should focus on developing a localized JIT framework and exploring digital technologies such as BIM and IoT as enablers of lean material delivery.
