Abstract: Schedule overruns are a major challenge in the construction and rehabilitation of wastewater treatment plants (WTPs). This can often lead to cost overruns, loss of productivity, construction quality problems, large punch lists, disputes, and claims.
This paper aims to develop empirical system durations for WTPs through the compilation of real-world WTP related as-planned and as-built schedule data and carry out regression analysis to model the relationship between the factors that affect the system durations (such as the size of the plant, the type of treatment process, and the age of the plant) and the system duration itself. This model can then be used to predict system duration based on the identified factors.
The results of the study can be used to improve the accuracy and reliability of WTP schedules by pre-emptively informing planners and schedulers about the numerous factors affecting WTP construction and providing them with empirical system durations which can be used as a reference point. This will help to set realistic stakeholder expectations, reduce the risk of schedule and cost overruns.
