Examining the Impact of Material Management Practices on Project Performance in the Construction Industry.

In the construction industry, much of the construction process is controlled by materials, and material management has a direct impact on many performance criteria such as cost, time, quality, and efficiency. This study examined the impact on project performance of activities that make up the material management process: planning, supply, logistics, transport, stock, and waste control of building materials. Material management practices were measured using 15 criteria under five different headings, and project performance was measured using 13 criteria under three different headings, through surveys of industry personnel at various construction sites. Multiple regression analyses were performed on the data obtained. The impacts of material management practices on project time, project cost, project efficiency, and waste performance, as well as overall project performance were examined using multiple regression analyses. The analysis showed that material supply, material handling, and stock and waste control had positive impacts on overall project performance, while material planning and material logistics did not have statistically significant impacts. It is concluded that the results of the study will help to better understand the relationship between material management and project performance and will help stakeholders to improve their material management practices.
