Date of Defense



The public nature of water and wastewater construction capital projects has rendered Design-Bid-Build (DBB) as the delivery method of choice for such projects over the past years. Shortcomings inherent to DBB have had a negative effect on the Key Performance Indicators (KPIs) of these projects. Numerous studies have argued that Integrated Project Delivery (IPD) improves the delivery performance of DBB projects. Project delivery performance is, however, a complex concept that is not easily measured. It involves several criteria with many factors that need to be accounted for. Water and wastewater construction projects do not have well-established overall performance rating models, and to date, no study has scientifically established links that correlate IPD principles to improvements in KPIs of DBB construction projects. The aim of this research is to develop a new model for rating the performance of water utilities major capital projects delivered using a project delivery method that combines IPD and DBB and use this model to find what correlation exists between the implemented IPD principles and the KPIs of these projects.

Data for water and wastewater projects were collected from water utilities in the three counties of South Florida. Forty-three projects were selected from the total population of water and wastewater construction projects and delivered using the traditional DBB delivery method. Selective IPD principles that are applicable to public projects in the water and wastewater field were then applied to two control projects, and their respective performance was measured using the previously identified KPIs. A Project Performance Rating (PPR) Model was developed to combine the key performance factors of a project into one performance index for water and wastewater construction projects and to gauge the overall project performance. Regression analysis and a focus group were then utilized to determine the effect of each implemented IPD principle on various project KPIs. Results showed enhancements in the performance of the delivery of public water and wastewater construction projects through the implementation of certain IPD principles. A guideline metric was developed that can significantly help utility owners aiming to predict how implementation of certain IPD principles can impact various project KPIs.
