Abstract
Network analysis makes use of critical path method to effectively manage and execute projects. Every project must be properly planned, scheduled and its completion time accurately estimated. As a result critical path method (CPM) is useful tool in project management and scheduling. This study employed critical path method to estimate the duration of a project in a building construction project using a case study of KLM Building Firm. The research design adopted was analytical, as it was suitable for the nature of the work. Secondary data on project activities were obtained from the construction site and used for the analysis. The (TORA) software were used to run the analysis. The result shows that the CPM is high efficient in estimating project completion time. The initial completion time of 45 weeks were reduced to 31 weeks by applying the CPM techniques. Based on this findings, it is recommended that management adopt CPM for proper decision-making, as its helps to save labour cost, reduce project during and increase organizational productivity.
