Abstract

The Materials resource accounts for 60% of the costs in a construction project. Despite its relatively high significance, not enough is paid to the materials supply, management and control process. Research indicats that the expected benefits from the use of materials management and control systems are: (1) Increased productivity and prevention of delays. (2) Lower materials surplus. (3) Less manhours needed for materials management. (4) Other benefits such as: smaller storage area, reduced purchasing costs, and improved cash flow.


The purpose of the present research was to develop a model, based on automatic data collection, for materials management and control. The model manages and initiates ordering of materials automatically, based on project plans, actual flow of materials and stock at the construction site. The model permits real-time control enabling corrective actions to be taken. Thus, costs and unnecessary traffic of materials is reduced. In addition, up-to-date information regarding materials flow is available and different statistical analyses are enabled. These are materials flow from a specific supplier, materials used for a given activity, materials used in a specific month, etc. The model enables to update the historical database to be used for planning of future projects and helps in determining the exact quantities and the waste for each activity. The use of the model minimizes the workload, saves manpower, prevent recording errors and thus reduces the many hours used for finding and correcting mistakes
