1 National Institute of Building Sciences National Building Information Model Standard Based on and supporting Industry Foundation Classes Information Delivery Manuals and International Framework for Dictionaries Agenda Overview Building Information Models NIBS National BIM Standard Project Committee November 2006 This presentation is a collaborative product of the NIBS NBIMS Project Committee. 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 1

2 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.

Systems use NA classifications such as Omni- Class and Uniformat and are transported/exchanged via IFCs Space is 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 Overlays are more abstract data - organizational, operational, functional, financial, non-fixed assets, resources, personnel, etc. that is data tied to the Systems and Space Reports or Extracted Data from BIM (examples from all classifications) Area Gross Volume Surface Quantities Materials & Types Net Usable Sq. Ftg. Linear Ft. Information Exchanges The reason for the information exchange (i.e. Desire to buy doors) Report on Door Objects Control 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 ) Input The information exchange BIM BIM Output The product of the information exchange (i.e. The quantity and specification data used to purchase and deliver doors. 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 10

11 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 Use of Information Exchanges to Support BIM 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.
