BIM, 3-dimensional, can incorporate 4D (time) and 5D (cost) virtual modeling of buildings, and all aspects of life-cycle facility management (6D?)
For BIM to be virtual a model of a buildings life-cycle, input is required from multiple sources: architects, architectural engineers, specifiers, estimators, scientists interested in performance modeling, constructors and construction vendors, computer software vendors, owners, facility managers, funding sources, management / leadership, and users.
Life cycle BIM includes real property commerce, maintenance and operations, sustainabilty / green / high performance, physical and functional conditions and needs, etc.
Standardized life cycle processes, taxonomy/definitions and associated communications are required.
Why BIM is important:
Owners—High level summary information about their facilities, planning, budgeting, decision support.
Planners—Existing information about physical site(s) and program needs
Realtors—Information about a site or facility to support purchase or sale
Appraisers—Information about the facility to support valuation
Mortgage Bankers—Information about demographics, corporations, and viability
Designers—Planning and site information
Engineers—Electronic model from which to import into design and analysis software
Cost & Quantity Estimators—Electronic model to obtain accurate quantities and share comparables
Specifiers—Intelligent objects from which to specify and link to later phases
Contracts & Lawyers—More accurate legal descriptions as well as more accurate to defend or on which to base litigation
Construction Contractors—Intelligent objects for bidding and ordering and a place to store gained information
Sub-Contractors—Clearer communication and same support for contractors
Fabricators—Can use intelligent model for numerical controls for fabrication
Code Officials—Code checking software can process model faster and more accurately
Facility Managers—Provides product, warranty and maintenance information
Maintenance & Sustainment—More easily identify, track, budget, and schedule; repair, replacement, maintenance needs
Renovation & Restoration—More easily identify, track, budget, and schedule capital reinvestment requirements.
Disposal & Recycling—Better knowledge potential reuse / adaptation.
Scoping, Testing, Simulation—Electronically build facility and eliminate conflicts, simulate growth needs.
Safety & Occupational Health—Knowledge of what materials are in use and MSDS
Environmental & NEPA—Improved information for environmental impact analysis
Plant Operations—3D visualization of processes
Sustainability, Energy, LEED—Optimized energy analysis including energy and condition analyses concurrently.
Space & Security—Intelligent objects in 3D provide better understanding of usage, flow, security issues.
Risk Management—Better understanding of potential risks and how to avoid on minimize
Occupant Support— Better wayfinding and visibility into availability.
First Responders—Timely and more accurate information
