The purpose of this paper is to investigate procedures and practices to promote transparency in best-value procurement for the design and construction of highway projects with the goal of improving this evolving procurement method.

The review of published empirical studies, a national survey of transportation agencies, and case studies of highway agencies form the basis of the conclusions in this research. In addition to the national survey, with 46 of 52 agencies participating, the research presents case studies from seven highway agencies in the USA including: California, Florida, Michigan, Minnesota, New York, Oregon, and Utah. These seven case studies were selected from agencies that employ mature best-value procurement methods. The case studies involved a thorough procedural review and structured interviews of agency personnel. The agencies then validated the results and conclusions.

The results showed that evaluation committees should include technical members who do not have a personal interest in the outcome of the selection to maintain transparency in best-value projects. The committees should receive best-value procurement training, which necessitates the development of consistent and transparent best-value selection procedures. Debriefing meetings should be conducted to provide comments about strengths and weaknesses of each proposal to enhance fairness and transparency of the best-value selection process.

Knowledge of the best-value procurement procedure will allow researchers to better understand the impact of procedures and practices on transparency in selecting best-value projects. The chief limitation of this research is that the primary data were collected from highway agencies in the USA. Any future research should include more data to enhance the validity of this study outside of the public transportation sector.

The result of this research will help transportation agencies and other public owners to improve their best-value procurement procedures. The findings of this research also address the construction and consulting industry’s concern about transparency and fairness of a best-value selection process.

This research is the first attempt to examine the impact of the evaluation committee, best-value training, and debriefings on transparency of best-value selection.

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.

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.

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.

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.

Understanding how state DOTs approach QA method selection will serve as a foundation for new methods of QA optimization.

Proper identification, allocation, and pricing of risks are critical to effective procurement and project delivery, particularly when contracts specify the intended performance instead of how the work is to be performed. This paper presents an overview of the sources of project risks when performance specifications are used for highway infrastructure procurement. The findings are based on a comprehensive literature review and interviews with subject-matter experts involved in developing performance specifications for highway infrastructure. The authors conclude that wider use of performance specifications in U.S. highway infrastructure construction requires a fundamental reassessment of risk allocation and pricing. Highway agencies and the contractors need to realign their respective organizational capabilities with the goal of using performance specifications as a facilitator of innovation, a goal that remains elusive after decades of applied research.

This article addresses the lack of formal design guidance that supports flexibility within the architectural and engineered systems of manufacturing facilities through the development of a taxonomy and associated terminology.

This research performed a comparative analysis of 15 manufacturing facilities located both within the United States (73 percent of cases) and internationally (27 percent of cases). These case studies provided details on how and where flexibility was incorporated into the design of a manufacturing facility. Specific consideration was given to the primary design features that enabled a decoupling of the facility from the manufacturing process. These design features were then clustered to identify main design strategies that enable flexibility.

By grouping the design features together and creating a common vocabulary, three coherent design approaches for flexible facilities were identified, each having a different potential for responding to short-term and long-term changes. These include general purpose, scalable, and dedicated facilities.

By delineating three high-level strategies for early flexible facility design, this research synthesizes a conceptual understanding of flexibility with practical and implementable designs. This synthesis provides an incremental advance to a complex challenge for researchers. It also provides decision support to design teams by aiding in project definition, when flexibility is desirable. This research is primarily limited by the number of cases reviewed. With more cases, additional facility design strategies may be identified.

The findings in this research allow for a basic understanding of how a flexible facility can be designed with only limited or vague information about the product and manufacturing processes contained within. The development of terminology associated with each facility design strategy provides standardization for the discussion and implementation of flexibility early in the design process. In doing so, flexible designs become easier to create and more efficient to implement.

This research provides the first synthesized approach for considering flexible facility design strategies within the manufacturing sector.

The increased need for, and maintenance of, infrastructure creates challenges for all agencies that manage infrastructure assets. To assist with these challenges, agencies implement asset management systems. The purpose of this paper is to investigate and compare the importance of barriers faced by agencies establishing transportation asset management systems in the USA and Libya to contrast a case of a developed and developing country.

A literature review identified 28 potential barriers for implementing an asset management system. Practitioners who participate in decision-making processes in each country were asked to rate the importance of each barrier in an online survey questionnaire. Descriptive statistics, Kendall Concordance W., and Mann-Whitney are used to analyze the collected data.

Through an analysis of 61 completed questionnaires, 14 barriers were identified as important by both the US and Libyan practitioners. A total of 11 additional barriers, primarily in the areas of political and regulatory obstacles, were determined to be important only for Libya. These 11 barriers provide reasonable insights into asset management systems’ barriers for developing countries.

The list of barriers identified from this research will assist decision makers to address and overcome these barriers when implementing asset management systems in their specific organizational and country conditions.

The research identified standard barriers to implementing asset management systems and identified barriers that were specific to the country context, such as political and regulatory barriers in Libya. When viewed with the asset management literature, the results show broad applicability of some asset management barriers and the need to contextualize to country context (e.g. developing countries) for other barriers.

The purpose of this paper is to investigate the impact of risk on the project delivery selection process of three primary methods in use in the USA, including design-bid-build (DBB); design-build (DB); and construction manager/general contractor (CMGC).

The review of empirical studies, national survey questionnaire, multivariate analysis, and cross-validating discussion are adopted for this research. The risk factors were identified through an exhaustive literature review and empirical studies that included more than $10 billion of transportation projects. Experts with an average of 25 years of professional experience related to risk and project delivery methods in the transportation industry were invited to participate in the survey.

There were six critical risk factors for DBB, seven for DB, and six for CMGC. These critical risk factors are ranked differently from each delivery method. The most critical risk factor for DBB is construction risk, for DB is scope risk, and for CMGC is constructability and documentation risk.

Knowledge of the risk factors will allow researchers to better understand the impact of risk on DBB, DB, and CMGC projects. The chief limitation of this research is that the primary data were mostly opinions from experts although several empirical data were collected for cross-validation. The future research may take into account the role of participant's risk aversion in project delivery decision frameworks.

Transportation agencies and other practitioners can use these risk factors to make more effective and defensible decisions on which delivery method is the most suitable for their projects. The result from this study provides a foundation for decision makers to use a risk-based approach in the project delivery decision.

This research is the first attempt to examine the impact of risk on the project delivery selection process.

Research into integrated project delivery (IPD) has attracted increased attention over the past 2 decades, and a significant number of IPD studies have been published more recently. The purpose of the study is to explore the state of IPD to reveal innovative areas of focus.

The research presented puts forward a science mapping and bibliometrics methods to study systematic analysis of IPD scientific output published between 2006 and 2020. It uses a framework from emerging literature relating to innovation to incorporate a perspective of the process of innovation for the analysis of IPD. The adapted framework from the literature on innovation, called the Technology Innovation System (TIS), has functions that reveal novelty in the existing structures of IPD. The framework uses the analysis of scientific output from science mapping and bibliometric study techniques, using the ScienceDirect (SD) and Web of Science (WoS) databases as sources. The framework analyzes factors involved in the development and diffusion of the IPD approach and charts new knowledge development on IPD.

From the analysis, future implementation of IPD will converge on cases of collaboration, as a systemic feature, among participating stakeholder teams. A significant and robust effect resulted from collaboration and integration as major mechanisms influence opportunities, problems and solutions within construction firms using IPD, marking a future trend. Reports further substantiate the importance and focus on collaboration and integration between IPD practitioners. With the same dynamic and gradual prominence, building information modeling (BIM) and new technology applications demonstrated the importance of the development and diffusion of IPD in the form of, for example, digital government initiatives. It is expected that the trend for IDS and resource mobilization functions will continue to grow – clear evidence of the benefits of the IPD approach in the construction sector. New evidence for gaining cognitive and normative legitimacy emerged. The expansion of new avenues for further legitimation is expected to enable growth.

Beyond the innovative approach of viewing IPD from the emerging innovation framework, the research presented fully contributes to IPD literature, providing a comprehensive state-of-the-art status and a quantitative analysis of IPD scientific output, thereby illuminating promising work areas for future research into IPD. The main limitation is related to the dynamic process of indexing of IPD literature in the WoS and SD – although many new research publications are added in the discipline, only a part of them have been indexed in the WoS and SD core database.

The study revealed key evolving trends within the field, including instructive findings and implications concerning possible deficiencies. Based on factors from network visualizations and quantitative evaluation from major influential articles, journals and authors, future critical IPD implementation focus will be on BIM and sustainability concepts – centerpiece concepts for the evolving line of IPD growth and development in the architecture, engineering and construction industry.

This study fills the gap created in a shortage of studies mapping out the most critical contributions in journals, authors and research perspectives related to IPD. It presents a framework that can be used as an objective procedure to evaluate the topic. It is expected that the study will serve as a cornerstone for researchers in this field, as it provides a bibliometric analysis and presents trends using an analytical framework of innovation.

The research presented is a keystone in the foundation of the literature review on this topic. The research draws on an existing framework for innovation – the TIS, developed from innovation studies using a robust theoretical framework to enable further analysis of IPD. This approach is one of a kind, using the results of scientometric analysis to study the scientific landscape and knowledge output of IPD in the AEC community. Science-mapping bibliometric analysis was conducted to shed light on IPD trends and explain factors that back or support the development and diffusion of IPD, including shaping and enabling evolution and growth. The framework helps to shed light on the interaction of socio-technical structures (i.e. stakeholders, technologies and rules) embedded in the industry, which helped create, direct and advance IPD in the project delivery system.

The purpose of this paper is to establish an integrated framework of the antecedents of enforcement after contract violations in construction projects and to examine whether contract provisions (control and coordination provisions) and trust (goodwill and competence trust) affect enforcement mechanisms (contractual enforcement and relational enforcement).

A survey method was employed to test the hypotheses. The authors collected data from the Chinese construction industry, and general contractor respondents were asked to answer a questionnaire about a contract violation by one of their subcontractors.

Control provisions and competence trust are positively related to contractual enforcement, but goodwill trust is negatively related to contractual enforcement. Relational enforcement is influenced by goodwill trust and competence trust.

This study treats contract violations as a given variable, and it focuses on contract violations by subcontractors. The cross-sectional design makes it difficult to confirm the causality of the relationships.

Overly strict contractual enforcement can generate disputes and a vicious cycle of retaliation, and overly severe relational enforcement can damage a potentially profitable long-term relationship. In construction projects, the violating party will benefit from this study to avoid excessively contractual enforcement and relational enforcement, thus developing a more collaborative atmosphere on the current project and even establishing a solid long-term relationship.

This study extends the project management literature by investigating the antecedents of enforcement after contract violations, an area not yet fully researched.
