Agenda

• Definition of BIM

• BIM Assisting in LCI Goals

• Removing Redundancy

• Reducing Waste

• Solidifying Cost

• Information Rich Model Available to Owner

6

Definitions

• BIM Building Information Modeling (BIM) is the

process of generating and managing building data

during its life cycle. Typically it uses three-

dimensional, real-time, dynamic building

modeling software to increase productivity in

building design and construction. BIM

encompasses building geometry, spatial

relationships, geographic information, and

quantities and properties of building components.

7

Definitions

• BIM Is the digital worlds’ example of the initiation,

conceptualization, realization and managing of a

building.

8

BIM Assisting in LCI Goals

• LCI Goals Maximizes value delivered to the customer

while minimizing waste.

9

• EPA 2003 estimated C&D waste of 170

million tons that’s 3.2 pounds per capita

per day (pcd)

• Previously calculated in 1996 as 2.8 pcd

BIM

BIM Assisting in LCI Goals

• BIM Is the digital worlds’ example of the initiation,

conceptualization, realization and managing of a

building.

12

• BIM Is a tool which allows for the digital prototyping of

a project. It’s intent is to be a repository of all pertinent project information of which access is readily available.

Non-Geometric Information

• Some areas accessible, most not

• Analysis information not always

transferable

Geometric Information

• Readily accessible

depending upon phase

Removing Redundancy

13

• NIST 2004 Report estimates 15.4 Billion Dollars in annual

interoperability cost.

• BIM can do only so much…..

• Contract development will assist in motivation….

• IPD, Design Build, Design Assist….

• Evidence based design will also have a hand in it…

Removing Redundancy

14

• IPD/Design Build

• Design Assist Approach

Convert Validated Geometric Information into AutoCAD and then

Tag it with Software Specific Information for Fabrication

Revit MEP CAD Duct – CAM Duct

Removing Redundancy

15

• IPD/Design Assist Approach

• Design Build

In early phases of Design (end of SD), Structural Model is

shared… Communication Continues with Fabricator…

Revit StructuralDATA

SDS/2

FABRICATION

Fabricator Model shared with Design and Construction Team

• Moving more field work to fabrication work.– More and more examples of this happening in Mechanical and Electrical

Trades.

• Trades that seem very efficient are benefitting from BIM.

– Architectural Precast Concrete

• Study from Georgia Institute of Technology March 26th 2008

• For a 20 story panelized building found that BIM was as much as 58% more efficient in

workflow compared to 2D (traditional) methods.

Reducing Waste

• Mining BIM

– Quantity Takeoff

• Queries the Database

• Quantifies Objects

• Update as Necessary

Solidifying Cost

23

• Whose is Driving it now…

– More Owners are now demanding BIM on Projects

• Model Progression Specification

• AIA E202

– Contractors

• Are progressing very fast.

• Scheduling / Conflict Resolution

• Cost Model

– A/E

• Design Simulations

• Quicker Decisions

Information Rich Model Available to Owner

24

• Whose Model???

– Design Team

– Construction Team

– Combination… or Is it Specially Focused Model

Information Rich Model Available to Owner

25

Summary

• Q/A or Open Discussion
