Agenda • What is BIM? • Promise of BIM • Current State • Barriers • Next Steps
What exactly is “BIM”? • Building Information Modeling • Perhaps one of the most misused terms in the industry • Contains graphical as well other types of information • That information can be either graphical or nongraphical, either contained directly in the building model or accessible from the building model through linked data that is stored elsewhere.
NBIMS Vision and Mission • Mission: Improve the performance of facilities over their full lifecycle by fostering a common, standard, and integrated lifecycle information model from the Architect, Engineering, Construction (AEC) and Facility Management industry.
NBIMS Vision and Mission • Vision: An improved planning, design, construction, operation, and maintenance process using a standardized machine -readable information model for each facility, new or old, which contains all appropriate information created or gathered about that facility in a format useable throughout its lifecycle by all.
Key Distinctions • Building Information Model – A digital representation of physical and functional characteristics of a facility. As such it serves as a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle from inception onward. • Building Information Modeling – How one uses the information model to support collaboration by different stakeholders at different phases of the life cycle of a facility to insert, extract, update or modify information in the BIM process to support and reflect the roles of that stakeholder. • building. SMART alliance – The North American chapter of an international organization with the mission to improve all aspects of the facility and infrastructure lifecycle by promoting collaboration, technology, integrated practices, and open standards.

The Promise of BIM BETTER BIM FASTER CHEAPER
The Promise of BIM
The Promise of BIM • Owner and Occupant – Be able to walk into an electronic model and know what they are getting – Be able to glean more information from the Model than from the facility itself • Designer and Contractor – Be able to simulate and visualize – Be able to identify problems before they are physical • Asset Manager – Be able to visually identify issues and focus on true problems – Be able to continuously commission and determine performance – Get top dollar for re-sale by validating performance
The Promise of BIM • Better visualization Benefits • Improved productivity • Elimination of conflicts • Faster delivery times • Automated shop drawings • Enhanced material fabrication • Reduced data collection • Higher quality buildings w/ better operating capabilities
Information Exchange Losses Management support information should be: • Collected continuously throughout facility life-cycle (created once) • Managed uniformly in standard framework • Securely available 24 x 7 Information Value of Improvements To-Be • Minimized data loss • Maximized information value Operation Planning Design Image courtesy Deke Smith – building. SMART Initiative Time Construction As-Is • Continuous data loss • Value of information reduced
Agenda • What is BIM? • Promise of BIM • Current State • Barriers • Next Steps
The State of BIM • Architects and Contractors are using BIM, however information is not yet flowing as the holistic vision has not been realized 74% of Architects Use Some Level of 3 D Digital Modeling NIBS - Results of AIA LFRT Survey
Standard: NBIMS V 1 P 1 • Delivered Dec 27, 2007 • International Core (ISO 16739) • National Specific – Omni. Class • Information Exchange Concepts • Standard Development Process • Information Assurance • Capability Maturity Model • References and Appendices • Over 30 contributors

BIM & LEED • Leadership in Energy and Environmental Design (LEED) – Validating LEED projects through commissioning and operations – Version 3. 0 requires more detailed information – Provide feedback loop to improve process Design Assumptions and analysis Design Testing and Validation Construction Comparison – If not equal then root cause analysis of difference and correction of assumptions and analysis tools

Lucas Films - School of Cinematic Arts
Lucas Films - School of Cinematic Arts The donor’s vision for the building: • Architectural function and aesthetics are the highest priority. • The building should exist for the next 100 years. • All design should be coordinated through the use of a “ 3 D” model. • At completion, USC will have a fully integrated BIM model.
Letterman Digital Arts Center • “Despite numerous design layout changes that were required by Lucas Film Ltd. due to company restructuring, the LDAC project was completed on time and below the estimated budget…. over two hundred design and construction conflicts were identified, most of which were corrected before construction, resulting in an estimated savings of over $10 million on this $350 million project. ” Courtesy of AECbytes "Building the Future" Article (September 30, 2006) Building Owners Driving BIM: The "Letterman Digital Arts Center" Story.
