bim what is it and why use it
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
building information model definition
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.

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

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

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

information exchanges
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

use of information exchanges to support bim
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

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.”

obtain a complete BIM with
