Transition from traditional to alternative project delivery methods in water and wastewater project: executive decision-makers' perspective

Abstract: PurposeThe purpose of this study is to determine the barriers and constraints executive decision-makers have to face during the delivery method selection stage of water and wastewater projects using alternative project delivery (APD) methods, e.g. design-build (DB), design-build-operate (DBO) and construction management-at-risk (CMAR).Design/methodology/approachStructured interviews were conducted with 18 executive decision-makers from public agencies to identify the reasons for transitioning to APD from the d… Show more

“…CMAR also allows for greater flexibility in making changes during construction [52]. CMAR can also provide early cost input, cost input during the design phase, helping to keep the project within budget; better risk management as CMAR assumes the risk of construction at a guaranteed maximum price, protecting the owner and more quality control as it may provide constructability reviews during the design phase, improving the quality of the project [53]. However, it may have some disadvantages, such as potential conflicts of interest between the construction manager and subcontractors, potential delays if the construction manager is not involved early enough in the design process, cost uncertainty as the final cost is not known until the design is complete and the guaranteed maximum price is established.…”

“…There will be also less competitive bidding because the selection of the CMAR is based on qualifications rather than low bid, which may result in higher costs. And lastly, there may be the potential for cost overruns if changes are made during construction [53][54].…”
