The following abstracts have been submitted for consideration for the 2014 Annual Meeting in New Orleans, LA. The final program will consist of approximately 100 tracks.
(BIM-1503) The Financial Impact of All-In Building Information Modeling
Primary Author: Mr Ken Stowe Autodesk, Inc.
Abstract: Many construction firms now use Building Information Modeling (BIM) and champions at those firms know BIM delivers significant benefits. Whether the benefits are significant enough to merit deeper BIM adoption is unclear at this point in the Architecture Engineering Construction (AEC) industry. In order to investigate this problem,the lead author conducted over 51 workshops worldwide with practitioners who presently use BIM and elicited cost and benefit expectations from them, formulated with available project case study data and research metrics on benefits of BIM. The workshops provided a structured approach to identifying the financial benefits of BIM in the AEC community. Through the workshop case study approach, a list of 19 of the most impactful benefits that accompany an integrated, "all-in" approach to BIM were identified. This paper describes these benefits in more detail, as well as the current limitations, and sheds light on attributes of BIM in the near future. The findings have the potential to help the AEC industry to make informed decisions to maximize returns on BIM investment and establish realistic success targets and measures.
(BIM-1591) Environmental Performance of Buildings: Linking Practical BIM to Practical Policymaking
Primary Author: Dr Alan M. Redmond
Co-author(s): Dr Bob Smith Tall Tree Labs; Mr Dana Kennish Smith buildingSMART Alliance
Abstract: The United States faces large and complex energy challenges due to our changing degrowth economy, changing population dynamics, uncertain technology funding and breakthroughs around fracking, gridlocked political goals, immature Public-Private Partnerships for Infrastructure, and aging public and private urban infrastructure. Previous energy projection models anticipate that U.S. energy demand will increase by more than one-third by 2030, with electricity demand alone rising by more than 40 percent. The main purpose of this paper is to assess an information system architecture for maintaining building-related performance criteria through an Urban BIM-FM model extending the nationís energy efficiency guidance prototypes with BIM-FM guidance and standards The following research methods and techniques will be discussed: i) pre-qualification of existing and new construction ICT; advancements with emphasizes directly related towards BIM, ii) identify BIM energy related investigations, and iii) assemble, store (data modeling), and disseminate (object-hyper linking) building and construction-related technical data. In conclusion, this paper will assist policymakers in making decisions which impact the entire building community and where possible, a united building community can influence an appropriate action.
(BIM-1620) Leveraging BIM for Project Planning, Scheduling and Controls
Primary Author: Mr Abhimanyu Basu PE Basu Technology Inc
Abstract: BIM is being increasingly used during design and construction of building projects. Much of the emphasis is on Clash Free Design and Zero Change Order coordination in the construction phase. This case study will show how to extend the uses of BIM beyond the usual low-hanging fruit (clash detection) and use the information in the BIM model to leverage planning, scheduling and project controls during the construction and commissioning phases of a project.
The location and room data in the BIM model are exported and combined with architectural and MEP schedules to provide visual planning and communication aids and spreadsheets for quantitative tracking of progress.
The data is organized and used to plan and sequence construction work zones, confirm schedule durations, identify just in time delivery options for major equipment, define and manage commissioning zones and report progress.
We will provide an overview of how the data is gathered from various sources, processed and attached to the model to provide the project control functionalities discussed above.
