    "description": "<p>Construction material management is an essential factor that adversely affecting the<br>\nperformance of construction projects. This study was conducted with an objective of<br>\nidentifying construction material management practice and its effect on project delivery<br>\nfor public building projects in Addis Ababa. Based on the responsibility of managing<br>\nconstruction materials, contractors were targeted as a study population. The study has<br>\ntargeted 40 contractors that are involved in public building projects those are currently<br>\nunder construction and used census as a sampling method. Intended data was collected<br>\nthrough structured questionnaire and 38 questionnaires were responded and analyzed<br>\nthrough both descriptive and explanatory methods by using a statistical software called<br>\nSPSS 23. The study has identified the contractors are using three types of material<br>\nmanagement process i.e. the material is supplied based on the schedule on Bill of<br>\nmaterial, use warehouse to store the materials and search supplier for the materials<br>\nwhen demanded. Among the three process types, type 1 is better in making the<br>\ncompanies better performers in cost. In most of the projects multiple supplier is used<br>\nfor single material. Problems in material identification, planning, vendor selection,<br>\nprocurement and construction phase are root causes for ineffective material<br>\nmanagement. Construction project material management process type significantly<br>\naffects the existence of cost overrun on the projects but does not affect the level of cost<br>\noverrun. On the other hand, Construction material management process types do not<br>\naffect the project time. Problems of material identification, planning, vendor selection,<br>\nprocurement and construction phase highly affect the cost overrun and time delay of<br>\nthe projects but effect of the vendor selection problems is lowest when compared to<br>\nother problem categories. Majority of Contractors in public building projects in Addis<br>\nAbaba are not using software to manage construction materials. To support<br>\nconstruction material management, this study has developed pertinent software. The<br>\ncontractors are recommended to improve their construction material management<br>\npractices and solve their material management problems by using the software.<br>\n&nbsp;</p>",
