Impacts of the Just-in-Time Management System in Construction Projects in Nigeria

Abstract

The construction industry is a very robust sector of any nation as it is responsible for all the infrastructural developments. In order to better achieve these, it is important to use the Just-In-Time (JIT) management system as construction projects rely on large inventories of materials, leading to high storage costs, wasted resources and the risk of obsolescence or material damage. Therefore, this study assesses the impacts of JIT management system in construction projects in the Nigerian construction industry, focusing on Edo and Delta States, with a view to improve efficiency and reduce construction wastages within the construction industry. For the methodology, the convenience sampling technique was used to elicit information from construction professionals in the study area. A well-structured questionnaire was distributed to the 324 conveniently selected respondents with 203 of them returned, representing a 62.65% return rate. Descriptive tools such as percentages and statistical tools such as mean score, standard deviation, factor analysis and t-test were employed for the study. It was discovered from the study that there are significant positive impacts of the adoption of JIT in construction projects as acknowledged by the construction professionals in the study area. It is therefore recommended that there should be the incorporation of technology in construction activities to further improve the inherent impacts.
