“…Finally, 45 percent of the survey respondents did not vary their QA approach on different project delivery methods. This perception contradicts the findings from previous research efforts ( Gransberg and Molenaar, 2004;Kraft and Molenaar, 2014) and the guidance in alternative project delivery manuals (Florida Department of Transportation, 2014;New York State Department of Transportation, 2005;Texas Department of Transportation, 2011).…”

“…DOT preferences, variations in interpretation of federal QA requirements and maturity of local industry can all influence QA decision making (Kraft and Molenaar, 2014). However, trends suggest that as agencies gain more experience with alternative delivery, they gradually implement policies through pilot or demonstration programs that shift greater responsibility for materials management to industry (Kraft and Molenaar, 2014; Molenaar et al , 2008).…”

Purpose Selecting an optimal quality assurance (QA) process can have significant implications on the long-term durability and lifecycle costs of transportation projects. Currently, the approaches used by state departments of transportation (DOTs) to optimize QA are undocumented and the impact of project-specific factors are unknown. The paper aims to discuss these issues. Design/methodology/approach State-of-practice was documented via a review of DOT guidance documents, standard specifications and minimum sampling and testing requirements; a survey of 58 state DOT representatives; and interviews with eight DOTs. Findings DOT approaches to QA management are very diverse but can be organized into five levels that range from ad hoc visual inspection of materials to DOT-managed sampling and testing. Project size, location and complexity have strong influence on the selection of a QA approach, but DOT demographics and project delivery method are less significant. Practical implications Present approaches to the selection of a QA approach are generally informal, subjective and do not involve formal risk analyses. A data-driven approach for transportation projects is clearly needed. Originality/value Understanding how state DOTs approach QA method selection will serve as a foundation for new methods of QA optimization.

“…Some articles suggest future research to validate the developed models (Antoniou and Aretoulis, 2019;Gharaibeh and Shirazi, 2009;Alasad and Motawa, 2015). Future work also can develop and modify the weight of the variables used in the developed models using weight estimation analysis (Yadollahi and Zin, 2014;Kraft and Molenaar, 2015). Also, Jin et al (2020a) suggested that future work can apply the developed model with other (Jin et al, 2019;Kumar et al, 2018).…”

Purpose Various approaches have emerged to assist practitioners in making more informed decisions in highway construction projects. However, industry practitioners are still using subjective ways to make decisions. Also, researchers have developed tools and techniques with similar objectives. Lack of information on what has been developed might lead to those issues. Therefore, this paper aims to review trends of evolution, pinpoint strengths and gaps in the literature and identifies potential future directions for decision-making research in highway construction projects. Design/methodology/approach A systematic review was conducted on published articles on decision-making in highway construction projects using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) technique. Findings The analysis of 101 articles revealed that existing decision-making research in highway construction projects targets improvements in four areas: feasibility, conceptual, detailed scope and detailed design. The four areas consist of sixteen subthemes that are detailed in this study. In addition, most research involved developing decision support tools and systems as well as decision-making models, techniques and frameworks. Lastly, several research areas have emerged, such as adding more decision criteria including those with uncertainties, expanding existing decision-making models into decision support systems, benchmarking decision criteria between different sample populations and exploring inter-and intra-relationships between decision criteria. Originality/value This paper provides an overview of existing research on decision-making in highway construction projects. Also, it reveals research gaps in the body of knowledge to point out directions for future research. Finally, industry practitioners can use the findings to develop strategies for effective decision-making processes.
