Abstract:
Construction Materials Management is a vital function for improving productivity in
construction projects. Poor materials management can often affect the overall construction time,
quality and budget. Currently, the construction material management practice in Gisozi sector is
believed to be poorly performed. Lack of standardized construction materials management
system is one of the key issues facing by the building industry in Gisozi sector. The main
objective of this study was to examine the impacts of effective materials management on
construction site performance. The specific objectives were to examine the performance level of
6
existing materials management process on construction project sites in Gisozi sector, to identify
the roots causes of ineffective materials management in Gisozi sector and to explore the
relationship between effective construction materials management process types and project
delivery in terms of cost overrun and delay in Gisozi sector. Ninety nine questionnaires were
distributed to project managers, project engineers, site engineers, engineer, and foreman, and
they were received and analyzed. The following data analysis techniques were used: descriptive
statistics were conducted to report sample characteristics, reliability and validity analyses were
performed to confirm robustness of the instrument, graphical presentation such as bar charts
were developed, and finally Average Mean Index Scale were constructed. The study results
revealed that, 46.7% of respondent’s organization obtain materials for sites without site
requisition by site engineer provisions, while 28.9% of respondent’s organization procure
materials for sites with site requisition by project manager provisions and 13.3% of respondent’s
organization procure materials for site by engineer. The results indicated that currently there is
no standardized and computerized construction materials management system applied in
Somalia. The researcher concluded that all contracting companies are interested in using some
techniques of managing construction materials such as creating and updating database for
materials categories from local and international suppliers. Finally, researcher recommends to
use computerized construction materials management systems on projects sites for improving
productivity in construction projects and to reduce effort and time, and to achieve more accurate
results.
