Abstract
Purpose: 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 been published about the benefits offered by integrated project delivery (IPD) in improving the delivery of DBB projects. Links correlating IPD principles to improvements in KPIs of DBB construction projects have not been established scientifically, thus leaving owners with no guidance on which IPD principle(s) to implement in order to improve a particular project KPI. The paper aims to discuss this issue. Design/methodology/approach: Actual data were collected from 43 water and wastewater construction projects – including two control projects with full implementation of selective IPD principles – and used to compute major projects KPIs. Regression analysis and a focus group are then utilized to determine the effect of each implemented IPD principle on various project KPIs. Findings: Implementation of open communication was found to have a significant effect on reducing project cost overrun, and the co-location of teams significantly reduced the time to respond to RFIs. Collaborative decision making significantly reduced the cost of field rework. Other IPD principles showed less-significant effects on project KPIs and were concluded to be ineffective at improving the projects' performance. Practical implications: An implementation framework is developed that can guide utility owners on which IPD principle(s) to implement in order to improve specific project KPIs. Originality/value: This study demonstrates that not all IPD principles will result in performance improvement of a project. A selective and cost-effective implementation of certain IPD principle will have to be based on the nature of the project and the particular KPIs targeted for improvement.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
