Goals and Objectives

Familiarize you with the concepts and

terms of BIM

Many topics presented here will be covered inmore detail in future units

Present the issues and obstacles involvedwith moving towards a BIM enabled

environment and process

Prepare you to beginworking in BIM

Management

What is BIM?

17/56

BIM is a descriptive term for

technologically advanced processes inbuilding design. BIM is characterised by

the creation and use of geometricallycoordinated 3D objects, enhanced by

associated computable data. The data istypically interrogated in a 3D environment,

and is manipulated to describe a buildingproject in many ways.

Whats a Model?

Simplified version of a concept, phenomenon,

relationship, structure, system, or an aspect

of the real world.

3D Model

31


32/56

2D Drafting and 3D Modeling

In 2D, Everything is a line

Circle = A round line

Square = 4 lines

Column = A closed, filled in line

Wall = 2 parallel lines

Door = A bunch of lines

2D Drafting and 3D Modeling

In 2D, Everything is a line

Circle = A round line

Square = 4 lines

Column = A closed, filled in line Wall = 2 parallel lines

Door = A bunch of lines

In 3D, we extrude lines to make surfaces andsolids

Boxes, Cylinders, etc

The BIM Difference

38/56

BIM Object Based Modeling

38

The computer understands a Wall is a Wall,

door is a door, etc.


39/56

Parametric Modeling

Parameter = Object specific data which drivesform or conveys information

39


40/56

Parametric Modeling

Parameter = Object specific data which drivesform or conveys information

Dimensional Info (length, width, area, volume)

Identification Info

Location Info

Materials

Type

Are there several variations on an object(wall/door/window)

What does technology now make possible,which is different from past practice?

New ways to convey information

New uses of Data, and Re-use of Data

New methods for collaboration, co-operation

New abilities to link Design to fabrication through

Integrated Project Delivery

BIM New v. Old


44/56

44

What does technology now require, which isdifferent from past practice?

New skills for more sophisticated software

New standards for coordinating data

New approaches to collaboration-process

New contracts and ideas about liability

SIGNIFICANTLY MORE PLANNING!

BIM New v. Old


45/56

Planning

What is our model to be used for?

Visualization? Documentation? Data

Extraction? Analysis?

What software should I use? What level of development and detail?

How can it or should it be shared?

When should it be shared?

Who will manage the data flow?

Types of Models

Not all models are created equal.

Design Modeling

Documentation Modeling

Construction Modeling Coordination Modeling

Design Modeling

Establish Design Intent

Architects

Emphasis on visualization rather than

accuracy Engineers

Used in Analysis

Not particularly useful for collaboration &coordination

49/56


3d model developed expressly for purpose of

2d documentation

Essence of what Revit does

Process can involve migration of DesignModel from 3d program to 2d drafting platform

Model should be accurate

Project coordinates & Element sizes

Appropriate for sharing in a collaborative

coordination environment

Can be an essential tool for complex building49

Construction Modeling

Accuracy is PARAMOUNT

Model intended for use in construction &

fabrication

Generating 2d drawings is not a key priority, Model can be used to generate shop drawings

Fundamental difference in HOWand WHYthe model is created

Wall Modeled as a

Column Modeled as

a single element

Slabs cut-off at wall

Column Modeled by

Slabs support walls

intended to be

constructed

An Activity based upon previously createdmodels

Either Documentation Models or Construction

Models can be used.

Created by Architects or Engineers or Buildersor Trades

Discipline v. Aggregate Model

Discipline is specific, Aggregate is combined For use in

clash detection, data extraction, program

check, timeline simulation, etc.

Writing Assignment

1. What does BIM mean to you?

2. Why are you taking this course?

3. How do you think it can help you

with your work?

I am interested in how clearly and concisely you cananswer this question. Grammar, spelling and writingability all count.
