Effective Materials Requirement Schedule 100% 80% 60% Strongly Agree(%) Strongly Disagree(%) Agree(%) Disagree(%) RNPP DMR GWTP MUSCCFPP DCRP Effective Materials Requirement 100 % 80 % Strongly Agree(%) Strongly Disagree(%) Disagree(% RNPP DMR GWTP MUSCCFPP In a construction project, materials account for more than 40% of the total project cost. A small saving in material cost through efficient management of materials can result in a large saving in the total project cost. One of the root causes of improper material management is that materials are ordered based on the information from the project schedule. Hence the study is conducted to optimize the cost through material requirement planning for District road construction based on site scenario. The study involves mainly three stages, namely factors identification, data collection, and analysis. Data collection on factors which are based on time, cost, quality, quantity, and location of various activities acquired. These were analyzed and optimization of cost is done through MRP [10]. Fig. 10: Effective Materials Requirement Schedule Challenges From the questionnaire survey in those five projects, we found that almost all projects have challenges in effective materials requirement schedule where the projects GWTP, RNPP, and DCRP have to face most challenges for the lack of estimating and scheduling the project in proper time. i) Materials Storage According to Safety Standards It is very challenging in a foreign-aided construction project in Bangladesh to store goods according to the project’s safety standard due to lack of enough storage space, proper previous planning about materials storage space in the mobilization period, and also lack of knowledge and training of materials handling and storage. But it is one of the most important aspects that reduce the project cost and construction- related accidents if it is maintained properly. Without proper storage of materials, a natural disaster can lose of many materials and their usefulness.
