“…The picture of a typical house type 36 is shown in Figure 1. The Critical Path Method (CPM) is a deterministic scheduling method commonly used in construction project scheduling (Rama et al, 2017). The advantage of CPM in project scheduling is that the calculation process to determine the completion time of a project is relatively easy (González-Cruz et al, 2022).…”

Construction housing projects involve many risks and uncertainties that can affect their completion time. To ensure a construction housing project is completed on time, an accurate duration estimate is required for each activity. Deterministic duration methods, such as the Critical Path Method (CPM), are commonly used in project scheduling for construction projects. However, this method may not always produce a realistic schedule as it uses only a single duration estimation for each activity. As an alternative, this study uses the Program Evaluation and Review Technique (PERT) which utilizes three duration estimates namely optimistic duration, most likely duration, and pessimistic duration. A house construction project with 23 activities was analyzed using CPM to find the critical activities which produced 59 days of completion time. The critical path duration was then analyzed using PERT. PERT calculations found that there was only a 15% probability to complete the project in 59 days, and the project needed 66 days of completion time with a 95% level of confidence. The findings of this study indicate that PERT can assist project managers in creating a more realistic project schedule by considering the risks and uncertainties in estimating the duration of its activities.

“…Rama et al [40] proposed a study on project planning using the deterministic and probabilistic models by network scheduling techniques. Using a building construction project as a case study and applying the two project scheduling methods namely PERT and CPM to determine numerically the different types of floating times of each activity and hence determined the central path which plays an important role in the project completion time.…”

Effective project management techniques are critical to managers and decision makers in handling projects in today’s competitive environment. It is required that with such techniques, managers can carry out projects and complete them within specified time and resource constraint. This research considers the application of Program Evaluation and Review Technique (PERT). PERT was used to analyze data collected from Mega Star Technical and Construction Company in charge of the renovation/building construction of renovaworks at 48 Forces Avenue, Old GRA, Port Harcourt, Nigeria. The technique was used to obtain the network diagram, critical path, expected completion time for the project and the probability of completion within a required date. Ms Project version (2013) software was also used for the analyses. Results obtained revealed that the project can be completed within record time and possess a very high probability of completing the project within a stipulated date.
