Transcription

1 National Institute of Building Sciences Based on and supporting Industry Foundation Classes Delivery Manuals and International Framework for Dictionaries BIM: Pushing Standards To The Edge National Building Model Standard Deke Smith, RA Chair, NIBS National BIM Standard Project Committee Federal Facilities Council October 31, 2006 This presentation is a collaborative product of the NIBS Project Committee.

2 Building Model Definition National BIM Standard Definition of BIM buildingsmart A Building 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 Delivery Manual Initiative. NIBS 2006

3 Goals 1. Define expansive scope of BIM Everyone starting from different points of view Breaking down stovepipes Developing awareness and appreciation of life-cycle approach 2. Define first and subsequent versions of the Standard Can t boil the ocean Need to know when and what information will be available Need to identify authoritative sources and ensure accuracy

Structural, MEP, Flooring, Ceiling, Exterior, Walls SPACE-Vertical Horizontal, Empty Room Void OVERLAYS Typically associated with building hierarchy elements. Example Furniture Example Assets Financial Equipment Rentable Space Classifications Phone Circulation Area Personnel Example Space Assignment Business Group Example Marketing Administration Components Zones Metrics Metrics Attributes Standards Metrics Attributes Attributes Metrics Example SUI,CI Example Secure Areas Systems Example FCA,MDI Systems represent the physical entities of the building. 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 from BIM (examples from all classifications) Area Volume Surface Quantities Materials & Types Gross Net Usable Sq.

14 The COBIE Example Construction Operations Building Exchange Conception & Definition Phases Identify items from the specifications that will require warranty information COBIE COBIE will will demonstrate demonstrate the the flow flow of of information information through through the the phases phases of of a a facility facility something something that that is is not not yet yet happening happening yet yet Is Is critical critical to to realize realize the the total total potential potential ROI ROI Procurement & Execution Phases Collect information as items are ordered and delivered such as who is warranting, when the warranty starts, how long is the warranty period, what preventive maintenance is required to keep the warranty in force Utilization & Closure Phases Read the information collected directly into your CMMS software to ensure that the warranties are supported

15 Today & Tomorrow Goal of version 1.0 is to establish baseline and make some initial recommendations It is only a starting point Define Overall Scope of BIM Identify Industry/International Foundation Classes (IFC s) as a key element Identify OmniClass Tables as key elements Creation of Delivery Manuals w/ Exchange Samples (COBIE) Identify International Framework for Dictionaries as a key element Introduce a Capability Maturity Model & Define a Minimum BIM Introduce the World View to BIM View Taxonomies Present Guidelines from several sources (GSA, NIST, USCG) Version 2.0 January 2008 Focus on Gaining Consensus on Additional Delivery Manuals (PCI, AISC, Others) Introduce Models & Structures Provide Initial Business Rules Include Additional IFC s to Fill Gaps Provide Initial Harmonization of Guidelines Support More Comprehensive Business Views Version 3.0 January 2009 Expanded Robust Model and Structure Expanded Delivery Models Additional IFC s
