Objectives: A research has shown that the construction materials account for more than 55%-60% of the total expenditure of a project. Efficient material planning plays a major role in the successful handing over of a project within the estimated cost and schedule. Methods: This paper mainly focuses on materials planning and inventory control as these are the major aspects of material management. S-curve analysis is performed to measure the fluctuation between estimated materials cost and market materials cost. The major reasons for this are identified by interviewing engineers and contractors. Inventory control techniques such as ABC classification as well as EOQ analysis are conducted. Findings: The result of the S-curve analysis show that the actual materials cost is higher than the planned materials cost in most cases. ABC and EOQ analysis are applied to maintain sufficient stock in inventory and any given point of time, to protect the materials in the inventory against damages, to reduce inventory holding costs, to overcome stock-out problems and to maintain the inventory in an optimal level. Sensitivity check is applied to the results of EOQ analysis. The stock-out of A class and B class material problems faced in the  construction site can be reduced by  the application of ABC classification and BOQ analysis. The total expenditure of inventory is less after the adoption of these simple inventory control techniques.  Conclusion: Instead of using costly software for inventory management, the engineers and contractors may use these simple inventory control techniques which are equally beneficial and economical.

Material Management System

Construction material represents a major component of the project cost. Therefore, it is essential to control material on construction job sites. Efficient material management system requires trade-offs and optimized balance among elements of material cost including purchase cost, storage cost, opportunity cost, ordering cost, and unavailability cost. Thus, there is a need to develop an automated method for optimizing the delivery and inventory of construction materials not only in the planning phase but also in the construction phase to account for introduced changes. In this research a novel genetic algorithm – multi-layer perceptron (GA-MLP) method is proposed to generate optimized material delivery schedule. Multi-layer perceptron (MLP) is utilized to improve genetic algorithm (GA) by generating memory to overcome local minima encountered in applying GA for optimization. This automated method supports contractors to buy construction materials with the least cost and without leading to material shortage or surplus. The proposed automated method has been validated through a numerical example. The obtained results demonstrate that GA-MLP outperform GA in optimizing construction material inventory.

Local Sourcing

Cost reduction measure on construction materials is very critical in the effectiveness of any construction material management. Negligence on this frustrates the integrated effort deployed in cost control of any building project. As the study aims at assessing the impact of some building material cost reduction strategies with regard to their sourcing, applications and designs for affordable houses, field survey research design method and activity sampling involving some of the major building materials were adopted. Data were analyzed using some non parametric tools like likert scale and chi-square to rank the level of effectiveness of the various materials’ cost reduction measures in the industry. It was also used to determine the impact level of the material management on the overall cost of the materials used in the construction of public building in Owerri. Spearman rank correlation coefficient was also used to examine the strength of relationship between the two major sources of the information.  Findings in the study reveal that local sourcing of materials is the most significant method of material management in cost reduction. Other methods in their order of significance for cost reduction are quality assurance, economic design and specification, and on-site production of materials. The various percentage cost effects however are found to be significantly dependent on the methods of material management adopted for the materials’ cost reduction in the study. It is therefore recommended that an effective legislative back-up be instituted with a very strong awareness on the need for robust development of local construction material resources, as well as advocate for more practical contact hours on the stressed areas in the appropriate curriculum of the building profession in all the tertiary institutions in Nigeria. Finally, appropriate checklist/indices for check-mating quality assurance on professional personnel and materials schedules; as well as enforcement of ‘buildability’ and maintainability analyses of building projects should be encouraged in the study area.
