BIM - What is it and why use it? • A BIM is a lifecycle information collection point for a facility • A BIM allows for the creation of facility information relationships • A BIM is focused on saving resources (dollars, time and materials) during each phase of the facility life cycle • The more mature the model the more usable it is – but any collected data is better that how we do business today © NIBS 2006
Building Information Model Definition National BIM Standard Definition of BIM – building. SMART A Building Information Model (BIM) is 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. A basic premise of BIM is 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. The BIM is a shared digital representation founded on open standards for interoperability. The National BIM Standard is part of the global building.

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 Time Construction As-Is • Continuous data loss • Value of information reduced © NIBS 2006
Notional BIM Project Savings Curve This is a draft – a team is working to put actual numbers to these notional curves Execution Stage Procurement Stage Construction Documents Stage Design Stage Project Delivery Selection Stage Conception Stage Utilization Stage Closure Stage Optimized approach with virtual modeling and analysis with reduced change orders & delivery time and lower operating and sustainment costs Typical approach failing to do routine maintenance and having to replace items earlier and more often Typical design/build approach with required maintenance The savings we are currently experiencing with faster delivery and fewer change orders The yet untapped $avings IAI “Building. SMART” model supports lifecycle data © NIBS 2006
Typical BIM Benefits Building Is a Verb Lifecycle Knowledge Readily Exchanged Real Objects Lifelike Properties Ongoing Uses • Better understanding of design concepts – shared understanding of issues • More focus on value-added tasks • Faster cycle times • Reduced errors and omissions • Less waste: rework, materials, time • Fewer translation errors and losses • Increased site safety • Better estimates – cost and time © NIBS 2006

Information Exchanges Control The reason for the information exchange (i. e. Desire to buy doors) Report on Door Objects BIM Output Input BIM The information exchange • Programmatic and Project Requirements or Constraints (LEED Silver requested by owner) • Normative standards by which data is collected or managed (Such as the IBC, NCS, IFC’s and Omni. Class™) Existing information already in the BIM is used as input and information that is gleaned from the exchange is also stored in the model (i. e. Attributes about the doors purchased, size, material, cost, instructions, fire rating, etc. ) NCS, IFC’s, Omni. Class The product of the information exchange (i. e. The quantity and specification data used to purchase and deliver doors. More information is added to the building information model in its appropriate spatially related location © NIBS 2006
Use of Information Exchanges to Support BIM • Requirement & Goal – Standardize on information needed for specific tasks within the building lifecycle – Development based upon open data standards used by all – Provides requirements to software companies • North America data standards – CSI, OMNICLASS, Uniformat – International Bldg Code – CIS/2 and other authorities © NIBS 2006
Case Study – 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.
