Abstract:
Effective material management is a critical determinant of construction site performance,
particularly for small and medium-sized enterprises (SMEs). This study examines the
impact of material management practices on construction projects in Gisozi Sector, Gasabo
District, Rwanda. The research assesses current material management practices, analyzes
their effect on project cost and time performance, identifies key challenges faced by SMEs
in material storage, supply chain management, and procurement, and proposes strategies to
improve material management efficiency. Data was collected through surveys and
interviews with SME stakeholders, complemented by case studies of construction projects
in the Gisozi Sector.
The study reveals that SMEs rely heavily on informal material management methods,
including manual inventory control, temporary on-site storage, and just-in-time
procurement. These practices contribute to cost overruns, project delays, and material
wastage. Furthermore, SMEs face significant challenges such as inadequate storage
facilities, unreliable supply chains, and inconsistent material quality, which exacerbate
these inefficiencies. The findings also highlight the detrimental impact of poor material
management on project performance, particularly in terms of budget and schedule
adherence.
To address these challenges, the study proposes strategies including the adoption of digital
inventory and procurement systems, the establishment of long-term supplier agreements,
improved storage and handling practices, and the promotion of waste management and
recycling. By implementing these strategies, SMEs can enhance material availability,
reduce costs, and improve the overall performance of construction sites in Gisozi.
