Item Cost Comparison of Collaborative and IPD-like Project Delivery Methods Versus Competitive Non-collaborative Project Delivery Methods(2012-07-16) Kulkarni, AditiCollaborative project delivery methods are believed to contribute to faster completions times, lower overall project costs and higher quality. Contracts are expected to influence the degree of collaboration on a given project since they allow or restrict certain lines of communication in the decision making process. Various delivery systems rank differently on the spectrum of collaboration. Because collaborative project delivery methods require owners and AEC stakeholders to meet frequently early in the delivery process, they are thought to add additional upfront costs to the project. The purpose of this study is to test if collaborative project delivery methods impart enough value so that the upfront cost incurred at the beginning of project is eventually surpassed by realized savings. Ideally, the extreme forms of project delivery methods, that is, Integrated Project Delivery (IPD) and Design-Bid-Build (DBB), should be compared to test the effects of collaboration on benefits to the owner. Due to difficulty in obtaining data on IPD and similarly scaled DBB projects, for this study, their close cousins, CM-at-Risk (CMR) and Competitive Sealed Proposal (CSP) were compared. The study engaged statistical comparison of cost of change orders and overall project cost performance of 17 CMR and 13 CSP projects of similar scales by same owner. Project cost performance observed under CMR projects was found significantly more than those under CSP. This study is expected to help boost confidence in the benefits of collaborative project delivery methods. It is likely that the results will encourage acceptance of IPD for public projects. Owners who were previously discouraged by the increased upfront cost of collaborative projects may also find interest in the results of this study.Item The impact of delivery methods on the profitibility of commercial construction(2011-12) Herndon, Michael Brett; Nichols, Steven Parks, 1950-; McCann, Robert B.According to September 2011 information from the U.S. Census Bureau, the construction industry in the United States is valued at nearly eight hundred billion dollars annually. A 2004 collaborative study by Construction Industry Institute and Lean Construction Institute suggests that as much as fifty seven percent of time, effort, and material investment in construction projects do not add value to the final product. When compared with twenty six percent wastes in the manufacturing industry, it becomes obvious that the construction industry has a problem. Construction projects that come in over budget and behind schedule have become the rule rather than the exception, leading to contentious business relationships and costly litigation. This study will strive to identify and analyze the primary sources of these problems. Research and industry experience point to a lack of communication and cooperation among the various entities required to complete a construction project as the leading causes of waste in the industry. Further analysis suggests that traditional forms of construction contracts encourage adversarial and non-cooperative behavior between parties. Additionally, poor communication between various contributors opens the door for additional wasted cost. Fortunately, the development of tools such as Integrated Project Delivery (IPD) and Building Information Modeling (BIM) present new options to construction professionals that are proving to help address some of the challenges the industry faces today. IPD as a project delivery method creates a culture of collaboration and teamwork, where a culture of risk avoidance and conflict once stood, while BIM provides a platform for better communication among parties. When used together, these tools can reduce or eliminate many of the major sources of waste within the industry. This thesis will provide descriptions, analysis, and case studies that demonstrate the use of these tools and the potential they have to make a positive impact on the construction industry.Item Studio Education for Integrated Practice Using Building Information Modeling(2011-02-22) O?zener, Ozan O?zenerThis research study posits that an altered educational approach to design studio can produce future professionals who apply Building Information Modeling (BIM) in the context of Integrated Project Delivery (IPD) to execute designs faster and produce designs that have demonstrably higher performance. The combination of new technologies and social/contractual constructs represents an alternative to the established order for how to design and how to teach designers. BIM emerges as the key technology for facilitating IPD by providing consistent, computable and interoperable information essential to all AEC teams. The increasing trend of BIM adoption is an opportunity for the profession to dramatically change its processes and may potentially impact patterns of responsibility and the paradigms of design. This study showcases a repeatable framework and a theoretical model for the integrated studio using BIM and provides answers to the pedagogical questions raised by BIM, integration, and performance-based design. Using a formative and exploratory action research design, the study proposes a comprehensive pedagogical framework using the established theories of design studio education, building integration, and BIM. The framework was refined and triangulated in a set of focus group studies that include academics, design firms and AEC industry representatives, as well as students. Instrumental case studies implementing the pedagogical framework were conducted as courses in a graduate architecture program. Students' design processes and collaboration schemes were observed using systematic methods that included a broad range of data in conformance with a multi-method research approach. Content analysis of the data provides qualitative evidence for the effectiveness and encountered challenges of BIM methods that is related to proposed studio framework. These findings are corroborated by descriptive statistics and numerical data from the surveys, simulations, reports, and BIM models. Findings of the study illustrate that a carefully designed set of course exercises that incorporate BIM can enhance design processes, increase the depth and the number of alternatives studied, catalyze an interoperable and integrated educational environment, and expand the scope of design learning. Case studies presented here suggest common patterns of collaboration between designers and consultants during the integrated design process using shared BIM models. The findings from the study are synthesized in two theoretical models for the BIM enabled integrated studio and collaborative processes.
