comparing construction manager general contractor and federal early contractor involvement project Delivery Methods
Transportation Research Record, 2016Co-Authors: Douglas D. GransbergAbstract:Past studies of the construction manager–general contractor (CMGC) project Delivery Method have focused on its use by state and municipal departments of transportation. The literature also includes the approach to the CMGC Delivery Method based on Federal Acquisition Regulation (FAR) termed early contractor involvement (ECI), which the literature classifies as merely a different term for CMGC. The desire to use CMGC project Delivery by the Federal Lands Highway Divisions stimulated a deeper study of the restrictions placed on federal agencies by the FAR and found that although CMGC and ECI project Delivery are indeed similar, they are not identical. The findings of that study are reported. A comparative analysis of the two project Delivery models is presented, and it is found that ECI Delivery is substantially different from CMGC Delivery because of FAR-based limitations on preconstruction services and pricing Methodology. It is concluded that the use of an incentive–disincentive scheme and the bidding of...

critical analysis of value added by independent cost estimate consultant to construction manger general contractor project Delivery Method
Transportation Research Board 92nd Annual MeetingTransportation Research Board, 2013Co-Authors: Jeanna Schierholz, Douglas D. GransbergAbstract:The Construction Manager/General Contractor (CMGC) project Delivery Method is an emerging project Delivery Method in the transportation industry. As part of its Every Day Counts (EDC) program, the Federal Highway Administration (FHWA) is promoting the use of CMGC through Peer Exchanges. One recurring theme of the Peer Exchange was the fact that value was added to a construction project during the preconstruction phase by the early involvement of the contractor and the Independent Cost Estimate (ICE) consultant. A content analysis of the presentations given at the most recent Peer Exchange in Boston, Massachusetts, along with four case studies from ICE consultants were reviewed along with literature on the topic to determine the extent of the value added to the CMGC process by involving the ICE consultant.

selection of project Delivery Method in transit drivers and objectives
Journal of Management in Engineering, 2011Co-Authors: Ali Touran, Keith R Molenaar, Douglas D. Gransberg, Kamran GhavamifarAbstract:This paper describes the results of research on alternative project Delivery Methods in transit projects in the United States. The research, sponsored by the Transit Cooperative Research Program, aimed to identify those factors that drive the decision in the choice of project Delivery Method. A rigorous case study analysis based on on-site structured interviews with the directors of several transit projects was used to identify decision drivers and the rationale behind the Delivery Method selection decision in transit agencies. The nine case studies conducted in this research represent a cross section of Delivery Methods, including design-bid-build/multiprime, construction manager-at-risk, design/build, and design/build-operate-maintain. The interviewees agreed that the use of alternative Delivery Methods have resulted in savings in schedule and cost for transit agencies. The research also found that achieving aggressive schedule compression is the most influential factor when selecting alternative delive...

impact of project Delivery Method on final project quality perceptions in the transportation industry
Transportation Research Board 90th Annual MeetingTransportation Research Board, 2011Co-Authors: Jennifer S. Shane, Douglas D. GransbergAbstract:Recent Transportation Research Board-sponsored studies on project Delivery Methods in airport, highway, and transit agencies found that many agencies have gained experience with alternative project Delivery Methods (PDM) and now consciously pair a transportation project’s requirements with an appropriate Delivery Method. These agencies have experienced successful projects using traditional Design-Bid-Build (DBB), as well as the integrated Methods, Construction Manager-at-Risk (CMR), and Design-Build (DB). This paper combines the results of the studies in the three modes and seeks to differentiate experienced practitioners’ perceptions in 19 agencies of how project Delivery Method choice impacts design and construction quality. Integrated project Delivery Methods’ major advantage was found to lie in the collaboration between the designer and the builder during the preconstruction phase. Preconstruction collaboration does not happen automatically by merely deciding to use integrated Delivery. This paper reports the results of structured interviews on this topic regarding those elements of preconstruction collaboration which were seen to have enhanced transportation project quality. It concludes that the most important factors are the qualifications and experience of the team and the ability to get early constructor involvement in the design process. It also found that the use of guaranteed maximum price rather than lump sum payment provisions in CMR and DB projects was perceived to maximize the benefits associated with these project Delivery Methods.

a system for selecting a project Delivery Method in us airports
Journal of Airport Management, 2010Co-Authors: Ali Touran, Keith R Molenaar, Douglas D. GransbergAbstract:Several types of project Delivery Methods are available to owners of publicly-funded airport projects. These Methods include design-bid-build, construction manager-at-risk, and design-build. This paper presents a Methodology for selecting the most appropriate Delivery Method for a given set of conditions. A set of 19 pertinent issues that can affect the choice of project Delivery Method are identified and described. The paper explains the distinguishing features of airport projects and combines previous research with the results of extensive interviews with nine US airports to develop a new decision support system. The developed system consists of two tiers. The first tier is a qualitative assessment where the decision maker evaluates the effectiveness of each Delivery Method in dealing with the relevant pertinent issues. This tier will assist agencies in determining if there is a dominant or obvious choice of project Delivery Method. If at the end of this stage a clear choice is not evident, a second tier is available where a weighted matrix is used to score competing alternatives. This system will also provide a structure for documenting the project Delivery decision in case the agency needs to explain and justify its decision.

decision support system for selection of project Delivery Method in transit
Transportation Research Record, 2009Co-Authors: Ali Touran, Keith R Molenaar, Douglas D. Gransberg, Kamran GhavamifarAbstract:A decision support system was developed to help transit agencies evaluate and choose the most appropriate project Delivery Method for their capital projects. The system considers the traditional design-bid-build, construction manager-at-risk, design-build, and design-build-operate-maintain Delivery Methods. A set of 24 pertinent issues that can affect the choice of project Delivery Method are identified and described. The described decision support system consists of two distinct tiers. The first tier is a qualitative assessment in which the decision maker evaluates the effectiveness of each Delivery Method for dealing with the relevant pertinent issues. This tier will help agencies determine if there is a dominant or obvious choice of project Delivery Method. If at the end of this stage a clear choice is not evident, the user will move to the second tier, where a weighted matrix is used to score competing alternatives.

a decision support system for project Delivery Method selection in the transit industry
2009Co-Authors: Kamran GhavamifarAbstract:The US government annually spends billions of dollars on transit projects. State transit agencies as the owners of these projects hire designers, construction contractors, vendors, and consultants to execute the project. An appropriate project Delivery Method can assist them in achieving the project goals. A project Delivery Method (PDM) is a framework of all project stakeholders’ legal relationships and responsibilities. The Delivery Method selection should be based on a systematic approach that includes all available PDMs and all of the project’s qualitative and quantitative characteristics that may be influenced by the Delivery Method option. This dissertation provides a comprehensive solution for this common challenge in the transit industry. The decision support system (DSS) developed in this research provides useful information and introduces the advantages and limitations of each PDM to the decision makers. A requisite well-structured decision making process is embedded in the proposed framework of this decision aid tool that is reliable and sufficient to solve the problem of selecting an appropriate PDM. The dissertation covers all the available PDMs (i.e. Design-Bid-Build (DBB), DesignBuild (DB), Construction Management at Risk (CMR), and Public-Private Partnership (PPP)). A comprehensive set of critical issues are defined in this dissertation and advantages/disadvantages of each Delivery Method is thoroughly studied with respect to these issues. Multi-attribute decision tools are also applied as another approach to select a PDM. Using quantitative risk analysis and concentrating on the effects of PDM option on the project risks is studied in this research effort. Highlighting the financial aspects of PDM selection is another core element of this dissertation in which some concepts such as Value for Money and Public Sector Comparator are explained and incorporated. The details of Net Present Value (NPV) calculation for PPP and conventional Methods and its implementation to a hypothetical project are presented in this dissertation. Several interviews and case studies were conducted to collect relevant information on the state of practice in the US transit industry and validate the developed system at the end.

project Delivery Method issues of different transportation modes one size does not fit all
Transportation Research Board 89th Annual MeetingTransportation Research Board, 2010Co-Authors: Douglas D. Gransberg, Ali Touran, Keith R Molenaar, Jennifer S. ShaneAbstract:Most previous project Delivery Method research has been concentrated on a single mode of transportation. Thus, it is problematic to generalize research results from one mode to another. This paper combines and synthesizes the output of three separate project Delivery Method research projects for highway, transit and airport transportation modes. Each study delved into the issues transportation agencies considered when selecting a project Delivery Method for a transportation project. The analysis finds that each mode of transportation views the various project Delivery Methods in a different manner. It concludes that the Methodology used to select a project Delivery Method must be grounded in the business and regulatory environment of the specific mode and that attempting to generalize the findings of a study of one mode to another is not appropriate

critical risk factors in project Delivery Method selection for highway projects
Construction Research Congress 2012American Society of Civil Engineers, 2012Co-Authors: Dai Q Tran, Keith R MolenaarAbstract:Selecting an appropriate project Delivery Method is a complex decision-making process due to risks and uncertainties. At the time of the decision, the owner and stakeholders often have little information and the project plans are not detailed enough to make a judgment about the project with certainty of outcomes. This paper examines 39 risk factors related to the project Delivery selection process. These risk factors were identified through completed cost and schedule risk analysis on more than $100 million of highway projects. A questionnaire was developed to collect the data a cross section of three Delivery Methods, including design-bid-build, designbuild, and construction manager/general contractor. Experts with an average of 25 years of related experience were invited to participate in the survey. The results indicate that the four risk factors that have most influence to all three Delivery Methods are: unexpected utility encounter; third-party delays during construction; geotechnical investigation; and delays in reviewing and obtaining environmental approvals. The research identified five other risk factors that have varying impacts on project Delivery selection constructability of design; Delivery schedule; railroad agreements; obtaining other agency approvals; and scope definition. This study also discusses the pertinent findings and rationale behind the critical risk factors.

decision support system for selecting the proper project Delivery Method using analytical hierarchy process ahp
International Journal of Project Management, 2005Co-Authors: Ibrahim M Mahdi, Khaled AlreshaidAbstract:Abstract Owners are presented with different options for their project Delivery process, which include the traditional Method (design-bid-build), construction management or design-build Delivery Methods. This paper examines the compatibility of various project Delivery Methods with specific types of owners and projects. While no project Delivery option is perfect, one may be better suited than another based on the requirements of a particular project. These requirements should be evaluated to determine which of the various options would most likely produce the best outcome for the owners. The proper selection of a project Delivery Method is based on a high degree of technical factors and low construction costs. In this study, a multi-criterion decision-making Methodology using the analytical hierarchy process is provided to assist decision-makers in selecting the proper Delivery Method for their projects. An example application for selecting the proper project Delivery Method for an actual project is provided.
