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 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.
