Construction resources including materials, labors, and equipment are extremely cost extensive in all construction projects. The management of these resources is a complex process, which significantly affects construction costs, quality and time. There are several factors that have been identified in the literature which contribute in enhancing the efficiency of resources management during the life cycle of buildings and optimizing the utilization of these resources. These factors are referred to as the Critical Success Factors (C.S.Fs). Therefore, there are required processes and data that should be identified in order to appropriately address these factors which are commonly referred to as the necessary procedures for success. These procedures depend on the availability of specific processes and data that are essentially needed while assessing the efficiency of resources management in the design, construction, operation and maintenance of buildings during its life cycle. This paper aims at identifying these necessary procedures (in terms of required processes and corresponding data), associated with the C.S.Fs that help in improving the efficiency of resources management. The research methodology adopted in this paper includes both content analysis and comparative analysis to identify the required processes and their corresponding data. The results presented in this paper include a formulation matrix that presents the identified necessary procedures of materials, labors, and equipment related to the C.S.Fs for assessing the efficiency of resources management during the life cycle of buildings. The matrix articulates the nature and type of required processes and their corresponding data along with the specific stages of buildings life cycle to facilitate the assessment of resources management efficiency. This matrix introduces an important tool for the designers and managers of construction projects to be utilized while conducting the assessment of resources management efficiency.
