| dc.description.abstract | This study was focused on the Impact of Construction Material Procurement on Costs and Completion Time of Public Building Construction Projects in Western Amhara Region. Procuring the required quantity and quality of construction materials as per the specification in contracts during the construction stage of a project is essential to accomplish the work within the specified time and cost. Currently, the procurement of imported materials like aluminum, rebar, ceramic, glass in Western Amhara Region is a challenging issue due to its scarcity and the increase in costs. In addition, the progress of building projects is affected by the delayed procurement and quality defect of local materials like masonry stone, gravel and sand. Generally, common material procurement problems in the construction industry are delayed deliveries, quality defects and incorrect quantity. The aim of this research was to study the factors that affect material procurement and investigate the subsequent effect on cost and completion time of public building projects. In order to examine the impact of material procurement on cost and completion time of building projects, a comprehensive literature review was carried out; subsequently, a questionnaire was designed to survey the current material procurement practice on public building construction projects in Western Amhara Region. A case study was also conducted to validate the results obtained from the questionnaire responses. Finally, the research finding showed that financial risk, scarcity of materials in market, improper specification, client’s specific requirement, rejection of material due to noncompliance to the specification, schedule is not planned before starting the project, material shortage or late delivery, delay in approval, delay in issue of purchase order, incompetent material suppliers are selected for project and flexibility for changes identified as the top ten factors which affect material procurement. Due to inefficient material procurement, usual percentage cost overrun were greater than 20% and usual time delay were greater than one year in Western Amhara Region public building. | en_US |
