Abstract - The objective of the present study is to understand about the problems occurring in the organization because of improper application of material management. In construction project operation, often there is a project cost variance in terms of the material, equipment’s, manpower, subcontractor, overhead cost, and general condition. Material is the main component in construction projects. Therefore, if the material management is not properly managed it will create a project cost variance. Project cost can be controlled by taking corrective actions towards the cost variance. Therefore a methodology is made to classify the materials by ABC analysis and these materials are identified and are taken up to measure the variations involved by S-Curve analysis and suitable measures are suggested using cause and effect diagram. This helped to suggest the root causes for many types of problems that were detected at the project site.
Keywords: Material Management, ABC (Always Better Control) Classification, Material, S- Curve analysis, Cost variance, Cause and Effect diagram.
1 INTRODUCTION
Materials management is a management process where coordination, supervision and execution of the tasks are related with the flow of materials in and out of an organization. Material management deals with principles and practices which effectively optimizes cost of materials used in the project. Material management is the line of responsibility which begins with the selection of suppliers and ends when the material is delivered to its point.
[10].Materials management is associated to planning, acquiring, storing and providing the proper materials of right quality, right quantity at right place in right time so as to co- ordinate and schedule the construction activity.
Materials management is the single manpower organisation concept embracing and planning, developing, and monitoring of all those activities and the line responsibility which begins with the selection and personnel primarily concerned with the flow of materials into and within an organisation [11].Study of Material Management suggests that real savings in cost can happen in improved labour productivity, reduced surplus, and improved cash flow. Suggesting the necessity for high level of attention towards materials has not been easy, however, despite the evidence that materials cover more than half of the project cost and the deficiency of
materials is the major cause of project delays.
2 DEFINITION
Material management is defined as “The function responsible for the coordination of planning, sourcing, purchasing, moving, storing and controlling materials in an optimum manner so as to provide a pre-decided service to the customer at a minimum cost.”
The International Federation of Purchasing and Materials Management accept the definition of materials management as “Materials management is a total concept having its definite organization to plan and control all types of materials, its supply, and its flow from raw stage to finished stage so as to deliver the product to customer as per his requirements in time.” It involves different functions like materials planning and controlling, purchasing, stores and inventory control. The materials manager has to manage all these functions with proper expertise and responsibility in the material management department.
3 METHODOLOGY ADOPTED
In preparing the explosion chart for Class A materials, the following methods have been adopted. The quantity of materials required for unit work has been arrived at by using standard rate analysis. The quantity and duration of the various works executed

64 have been taken from the project estimatesand project schedules which are updated on a monthly basis. The Material Explosion Chart has been formulated by combining the above two steps.

4 CONCLUSIONS
The study clearly shows the importance to manage all materials from the design stage to the construction stage. The systematic literature review identifies that materials management processes require a transformation to improve the overall process in handling of materials for more efficiency and effectiveness on the construction site. This is because poor handling of construction materials affects the overall performance of construction projects in terms of time, budget (cost), quality and productivity.
