The development of Building Information Modelling (BIM) guidelines for campuses and universities has evolved on a case-by-case basis and there is no standard format in the development of these guides. There are however, common elements in these guidelines. This study reviews the applications of Building Information Modeling (BIM) from the perspective of owners of higher education campus facilities and proposes a structured approach to develop documented guidelines to assist the owner’s staff in the use of BIM, primarily with existing facilities. More specifically, this study proposes a set of guidelines to assist the Facilities Management department at Worcester Polytechnic Institute (WPI) in using BIM for their existing campus facilities. Since 2005, WPI has been using some components of BIM in the design and construction of new facilities and has extended BIM uses to support facilities and space management in some of the existing buildings. Some positive experiences and benefits have been derived from these applications, but to date no formal and systematic approach has been established in documenting and organizing processes for the different BIM uses on campus. The objective of this research project is to conduct an extensive review of documented approaches and guidelines for BIM uses developed by other universities and incorporate the different experiences with the use of BIM at WPI to create a set of formal guidelines exclusively for WPI for the efficient implementation of BIM in future design, construction, renovation, facility, and space management of a facility. The research collected information from the WPI Facilities Management department through surveys and interviews, to better understand the current issues associated with facility management and space planning. A case study analysis that involved the use of 3D Building Information Models of several buildings on the WPI campus was performed to validate the possible use of the BIM in the efficient delivery of information for new and renovation projects as well as for its ability to benefit in the space planning process. Existing documented guidelines developed by five other universities that have pioneered the development of their guides were also reviewed to determine common elements in their BIM-based practices and to incorporate these when applicable into the BIM guide for WPI in such a way that will effectively contribute to the BIM adoption and standardization of procedures reflecting the unique characteristics of this institution. This study identifies the benefits of utilizing BIM and standardization through the BIM guide primarily for existing construction and facilities management. The attempt to identify commonalities and standard pieces to develop a BIM guide for WPI will help improve overall operational efficiency and productivity of the organization. This provides a unique opportunity to be engaged in the process of standardization, using existing content as a reference to achieve harmonization of concepts, terms, definitions and the overall structure or framework that the documented guide is delivered within. The outcome is a WPI-BIM guide which will help assist facility owners in developing an overall BIM strategy that supports the organization’s core goals, develops the necessary contract conditions, and generates implementation plans to successfully execute BIM within the organization.

In the Architecture, Engineering and Construction (AEC) industry, inadequate collaboration between project stakeholders and disciplines often leads to conflicts and interoperability issues. Research has been conducted in knowledge formalization to bridge the knowledge gaps and information silos. Formalizing construction knowledge is challenging to formalize because most construction knowledge implicitly resides in the minds of construction experts, which is difficult to represent in a formal and explicit manner. The proposed study is built upon previous research findings, and attempts to formalize tacit knowledge in Mechanical, Electrical and Plumbing (MEP) design coordination by capturing necessary information with a model-based information capture system and reasoning about the captured data with data mining techniques. The vision of this research is that the formalized knowledge can be used to provide guidance for early design review incorporating construction considerations, facilitate structured learning from past experience, as well as train novice engineers. In summary, this research has three main contributions. First, this research presents a formalized knowledge representation schema to capture process knowledge in design coordination, which was successfully implemented in a model-based knowledge capture system developed by the author. Second, a model-based knowledge capture system was developed to store clash information in the form of categorized features and link such categorized information directly to the relevant model elements, which can also facilitate organization and management of clashes and supports searching and grouping functions. A prototype system was developed as a plugin to a widely used BIM-based design coordination application and was demonstrated with project data gathered from three new construction projects in the United States. Third, this research applied data mining techniques for knowledge discovery and reuse in MEP design coordination. Classification models were developed to provide predicted solutions for identified clashes based on historical data. The classification algorithms that produced the best results were selected, which reached precision rates of over 70%. The effectiveness of the classification models was tested in a novice experiment. / text

Sustainable development issues and environmental concerns continue to gain headlines as demand within Canada’s residential construction industry escalates. Current construction practices adhere to traditional methods of construction, with inherent weaknesses such as high labour costs, negative environmental impact during and after construction, and minimal technological advancement. Many programs exist to rate building environmental performance, including Leadership in Energy and Environmental Design (LEED) and Built Green, which are primarily performance-based, not practice-based evaluations. Considerable research has supported these performance ratings; however, there has been very little research in construction practice ratings. Hence, the purpose of the research presented in this thesis is to bridge this gap by proposing a construction practice rating program in order to challenge builders’ claims of being sustainable. Although rating programs should include measurements of both performance and practice—given that great performance does not equal great practice, particularly if the standard of performance achievement is low, current programs are based on performance alone. The goal of this thesis is to enhance the sustainability of the residential construction practice through the incorporation of sustainability evaluation rating tools. To achieve this goal, a framework has been developed which encompasses sustainability rating tools that include an integrated construction practice rating program, an application of Building Information Modeling (BIM) for carbon dioxide (CO2) emissions quantification, and implementation of a mathematical linear optimization model as a tool that minimizes cost while incorporating user-defined preferences and numerous environmental criteria under a green building rating system. CO2 emissions of various house construction stages are quantified and utilized in a 3D BIM. Application of the proposed framework is demonstrated in a case study with findings that show the weak results of sustainability ratings for a particular home builder. Hence, the findings in this research demonstrate a residential builder’s ability to measure his sustainability efforts and enhance construction practices based on a rating analysis. The introduction of BIM for quantifying emissions in the construction process is found to be of significant value. / Construction Engineering and Management

This study investigates the use of Building Information Modeling (BIM) and COBie for Facility Management on three projects where these concepts were used. Factors which affect these concepts are identified through a literature review. The study is divided into the sections of Responsibility for database formulation, Characteristics of database, Technology and Effect on work order response times. A qualitative analysis is conducted to study the application of these concepts and identify any problems encountered. A case study is conducted on three projects where BIM and COBie were used for facility management. It is found that though the database generated by using these concepts is useful for preventive maintenance, the data gathering and formulation process needs to be started during the design and construction phase to make use of BIM for facility management functions like space allocation, 3D mapping, building automation etc. This study can be used as a reference for further research based on quantitative analysis of the factors studied in the case study.

Building Information Modeling (BIM) model contains information about structural, architectural, MEP (Mechanical Electrical and Plumbing) and other numerous components of a building. Among these components, MEP constitutes about 50% of the project cost, and its design is relatively more complex because of the limited headroom available to locate these components. The coordination of these systems involves locating and routing several subcomponents in a manner that satisfies different types of constraints. The earlier version of BIM Computer Aided Virtual Environment (CAVE) did not have provisions to show the overhead components of a BIM model. Conventionally, models had to be tilted to visualize the overhead components. The process of tilting the models to look up is considered counterintuitive. Some of the popular CAVEs developed by leading Universities have a screen on top to show the overhead components but they have a major shortcoming with them. The BIM models had to be converted to a specific format before they can be visualized in the CAVE environments. This study is an attempt to address the shortcomings of the previous version of the BIM CAVE by suggesting a prototype setup with a 55" LCD screen on top of the existing three vertically placed LCD screens. The addition of one more screen on top increases the vertical field of view, that is, the extent to which the user can see vertically in a BIM model. The new BIM CAVE setup is run by a custom built application that makes use of the .Net API (Application Programming Interface) of the commercially available BIM application, Autodesk Navisworks 2012, to control the camera views for achieving an almost seamless semi-immersive virtual environment. The main objective of this research is to validate the effectiveness of the new setup suggested by using a qualitative research methodology called phenomenological study. Semi-structured informal interviews were conducted with the subject matter experts (SMEs) who are experienced in the field of BIM to know about the differences in the user experience after adding a screen on top of the earlier BIM CAVE setup. The main idea behind this qualitative research technique is to develop an understanding of how the SMEs perceived the idea of looking up to see the overhead components of the BIM model. This thesis explains the steps followed to develop the modified BIM CAVE setup in detail and findings of the qualitative study to know about the effectiveness of the suggested new setup.

Apesar da necessidade de melhorias nas obras públicas no Brasil, inclusive no tocante à redução de irregularidades, o uso do BIM, no setor público, ainda é incipiente. Devido a isso, existem poucos exemplos de obras públicas projetadas e executadas nessa tecnologia, bem como estudos da área acadêmica brasileira nesse setor, em especial, existe uma lacuna sobre o emprego do BIM nas fiscalizações de obras públicas. Assim, esta dissertação tem o objetivo de avaliar o potencial da aplicação da tecnologia BIM no auxílio das atividades desempenhadas pela equipe responsável por fiscalizar o contrato de execução das obras públicas federais. Para desenvolvimento deste trabalho foi feita uma revisão bibliográfica acerca do BIM e fiscalização de obras, a partir dessas pesquisas foi estabelecida uma relação entre os benefícios do BIM e as atividades de fiscalização de obras. Em seguida, foi aplicado as conclusões obtidos dessa relação a um estudo de caso. Como resultado principal, conclui-se que o uso do BIM 4D e 5D melhora a qualidade dos projetos, planejamento e do levantamento de quantidades e controle do custo, munindo os fiscais de informações mais qualificadas para controlar e exigir o cumprimento do contrato por parte da empreiteira e consequentemente melhorando a performance da fiscalização. _______________________________________________________________________________________________ ABSTRACT / The improvement of the quality of the projects with the assistance of technology Building Information Modeling (BIM) has been reported in several researches, this fact motivates the adoption of this technology in various countries of the world, and some even have made the use of BIM required due to several benefits from this technology in construction. Despite the need for improvements in public works in Brazil, including as regards the reduction of irregularities, the use of BIM, in the public sector, is still incipient. Because of this, there are few examples of public works designed and implemented this technology, as well as studies of Brazilian academic area in this sector, in particular, there is a gap on employment of BIM in the inspection of public works. So, this dissertation aims to evaluate the potential of BIM technology application in aid of the activities performed by the team responsible for overseeing the execution of public works contract. For the development of this work was made a bibliographical review about BIM and supervision of works, from these surveys was established a relationship between the benefits of BIM and supervisory activities. Then, we applied the conclusions obtained this relation to a case study. As a main result, we conclude that the use of BIM 4D and 5D improves the quality of projects, planning and survey of quantities and cost control, giving the most qualified information for supervisor of contracts and require the fulfilment of the contract by the contractor and therefore improving the performance of the supervision.

Master of Science / Department of Architectural Engineering and Construction Science / Charles L. Burton / Building Information Modeling (BIM) is a new way of approaching the design, construction, and management of a building. It is an innovative method that bridges the communication gap between the architects, engineers, and contractors. By definition Building Information Modeling is a model-based technology linked with a database of project information. BIM builds a virtual model of the building so that architects, engineers, and contractors can all access at anytime. With BIM, architects and engineers are able to efficiently generate and exchange information, create digital representations of all stages of the building process, and simulate real-world performance. By doing this, many errors are eliminated in the field which increases productivity and improves quality. This report defines what BIM actually is and discusses the benefits and challenges that are associated with this new method of design and construction. Specifically, this report will take an in depth look at how BIM affects MEP design.
