AN EVALUATION OF FACTORS AFFECTING MATERIALS MANAGEMENT IN CONSTRUCTION SITE, A CASE STUDY OF IMO STATE
1.1 Background of the Study
Material management can be defined as a process that coordinates planning, assessing the requirement, sourcing, purchasing, transporting, storing and controlling of materials, minimizing the wastage and optimizing the profitability by reducing cost of material. Baldva (1997) noted that Materials management is a process for planning, executing and controlling field and office activities in construction. While Eduardo (2002) viewed Materials management as the system for planning and controlling all of the efforts necessary to ensure that the correct quality and quantity of materials are properly specified in a timely manner, are obtained at a reasonable cost and most importantly are available at the point of use when required.
According to Khyomesh and Chetna, (2011) Building materials account for 60 to 70 percent of direct cost of a project or a facility, the remaining 30 to 40 percent being the labour cost. Therefore, efficient procurement and handling of material represent a key role in the successful completion of the work. It is important for the project manager to consider that there may be significant difference in the date that the material was requested or date when the purchase order was made, and the time at which the material will be delivered. These delays can occur if the contractor needs a large quantity of material that the supplier is not able to produce at that time or by any other factors beyond his control. Chan (2002) noted that the project manager should always consider that procurement of materials is a potential cause for delay. The management of Construction processes to reduce, reuse, recycle and effectively dispose of wastes has a serious bearing on the final cost, quality, time and impact of the project on the environment. (Dania, 2007)
The goal of materials management is to ensure that construction materials are available at their point of use when needed. The materials management system attempts to ensure that the right quality and quantity of materials are appropriately selected, purchased, delivered and handled on site in a timely manner and at a reasonable cost, (khyomesh and chetna 2011). The scope of materials waste is vast, and this waste occurs in the industry irrespective of the size of the building firm, instructions about handling, storage and stacking are not provided with the goods or sent in advance to the site (Abdulazeez, 2000).
