  2. 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

  3. Building Information Model Definition National BIM Standard Definition of BIM – buildingSMART 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 buildingSMART Information Delivery Manual Initiative.

  8. What is Building Information Modeling [BIM]? • 2D Lines and Text Building Is a Verb • 3D Polygons • BIM • Virtual Construction • 3D Visual • Coordinated dataset • Interoperable Lifecycle Knowledge Readily Exchanged Real Objects • Installation photo • Built to the model Images courtesy FacilityGenetics, LLC and Ghafari Associates

  9. Accurate steel members - Size, weight, performance, cost. Accurate connections Accurate 3D position Simulation of - Installation process & equipment requirements - lighting - structural performance - etc. Overlap with other 3D elements to identify collisions. - Mech, elec, plbg, - Walls, ceilings, FF&E - Access for maint. & repair How Does BIM Work? For Example… Building Is a Verb Courtesy: Kling Lifecycle Knowledge Readily Exchanged Real Objects Lifelike Properties

Data Commissioning for Facilities Operations & Management Building Is a Verb DATA FUNCTION • Real Property • Space • Equipment • Utilities • Maint.

  12. Typical ‘Value’ Engineering ! Virtual Building Design Proposed Entry 25% 75% Lifecyclecost Strategy Design Construction Operation Influence vs Cost Curve Cost of Changes Ability to Change Effort

  13. Value of Improvements • To-Be • Minimized data loss • Maximized information value Information Value Operation Construction Design Planning • As-Is • Continuous data loss • Value of information reduced Time Information Exchange Losses • Management support information should be: • Collected continuously throughout facility life-cycle (created once) • Managed uniformly in standard framework • Securely available 24x7

  14. Notional BIM Project Savings Curve This is a draft – a team is working to put actual numbers to these notional curves Procurement Stage Execution Stage Project Delivery Selection Stage Conception Stage Design Stage Construction Documents 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 “BuildingSMART” model supports lifecycle data

  15. Lifecycle Knowledge Readily Exchanged Real Objects Lifelike Properties Ongoing Uses VALUE Typical BIM Benefits Building Is a Verb • 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

  19. Hierarchical Building Information Relationships Systemsrepresent the physical entities of the building. Systems use NA classifications such as Omni-Class and Uniformat and are transported/exchanged via IFCs Attributes BUILDING Or Structure Metrics IFC objects, relationships, space SYSTEMS –Ex. Structural, MEP, Flooring, Ceiling, Exterior, Walls Spaceis physical in nature, but can be unbounded (have no or cross physical boundaries) but it will always be tied to the physical structure or systems in some way Attributes Attributes Metrics Sub-Systems (part of systems) Metrics Components Overlaysare more abstract data - organizational, operational, functional, financial, non-fixed assets, resources, personnel, etc. that is data tied to the Systems and Space SPACE-Vertical Horizontal, Empty Example SUI,CI Metrics Level (Stories) Room Attributes Standards Void Metrics Vertical Reports or Extracted Data from BIM (examples from all classifications) Attributes Area Gross OVERLAYS – Typically associated with building hierarchy elements. Example Furniture Equipment Phone Net Example Rentable Space Circulation Area Volume Financial Classifications Assets Usable Surface Example Space Assignment Business Group Sq. Ftg. Example Secure Areas Systems Quantities Personnel Zones Linear Ft. Materials & Types Example Marketing Administration Example FCA,MDI Business Groups Metrics

  20. Information Exchanges • 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 OmniClass™) Control The reason for the information exchange (i.e. Desire to buy doors) Report on Door Objects BIM Output Input The product of the information exchange (i.e. The quantity and specification data used to purchase and deliver doors. The information exchange BIM 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, OmniClass More information is added to the building information model in its appropriate spatially related location

  21. 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

  22. 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" StoryMieczyslaw (Mitch) Boryslawski, Associate AIA Founder, View By View, Inc.
