Network Analysis on Phase 1B Building of the University Health Centre, FUTA, using Critical Path Method (CPM) and Program Evaluation Review Technique (PERT)

Abstract

Project planning and scheduling plays a vital role in estimating the time and cost angle of a project. Finalizing a project on time and within the budget is challenging. This study focused on finding the shortest possible time required to complete the phase 1B Building project of the University Health Centre, FUTA and also to evaluate the probability of completing the project within the stipulated time. This project work has been able to give a concise view about network analysis in building construction; definitions of some terms commonly used in network analysis was also stated. Also, an introduction to CPM and PERT was stated; assumptions of CPM, advantages and disadvantages of CPM were stated; assumptions, advantages and disadvantages of PERT were also stated. Data analysis was carried out and all the possible routes of the activities involved in the building project were found; the location of the critical path of the building project was also found; the expected duration for every activity in the building project was determined; the probability of completing the project within the stipulated time was also evaluated. The results showed that there is a 50% chance for the project to be completed within the stipulated time. With the information gathered on the building project, the project was delayed due to some factors such as low circulation of money, inadequate equipments, loss of some weeks due to a change in plan, and inadequate manpower; thus, there was a two month difference between the initial completion and the now actual completion time.
