Tonight‟s agenda

5

Essentials of Intelligent 3D modelling

High quality single discipline models

Model requirements and intents understood

BIM/Object Modelling packages used?

Basic surface/solid modelling methods?

Precise geometric sizes and locations for all

objects

Objects fully populated with appropriate

properties and attributes

Information embedded or linked in appropriate

and consistent manner


6

Benefits of Intelligent 3D modelling

Traditional views/drawings/documents can, if

required, be automatically extracted and internally

consistent

2D plan, sections,elevations, details

automated schedules, quantities & e-

specifications

4D construction scheduling

3D visualisations of complex areas &

perspectives. Sun studies and animations.

Extracts of quantities, areas, volumes etc.


7

Purposes of digital exchange

3D geometry used for clash detection for Design

Phase

Creation of Project Life Cycle BIM Model

For construction/fabrication for limited trades only

for coordination and clash detection

For analysis or simulation of building performance


8

Graphic/Visual coordination

Dimensional coordination

basis for 3D geometry use and set-out:

ACCURACY is CRITICAL!

Analysis

LCA, environmental or estimating analysis

software use.

Orientation and detail of model elements is critical

(e.g. sun studies, lighting analysis with correct

information included)

Model merging for checking/clash detection


9

The common BIM model file data is shared by

two or more project participants in an iterative

collaborative process.

Much effort is required to:

Establish compatible file formats and workflow

Manage versions

Organize object selection

Manage orientation of models

Feedback the information


10


11

One-way collaboration

BIM model file is exported to other participants for

visualisation, communication, assessment,

analysis, simulation or discipline design.

Marginally useful

Doesn‟t allow for feed back loop!

Design is ITERATIVE!

Links between applications

ODBC, COM, GDL or MDL

Geometry formats

DWG, DXF, RVT, DGN, SKP, 3DM, etc.

Intelligence is usually lost in this type of translation

Open exchange / interoperability formats

IFC or CIS/2.

Intelligence is retained in this type of translation

(hopefully!)

XML-based, DATA exchange formats

gbXML, OGC and IFCXML

Digital File Formats

Interoperability

Understanding the different file formats is

essential in managing data flow between

disciplines, users and software platforms

This is key to unlocking true collaboration

between disciplines and teams

RARELY is everyone working on the same

platform!

What‟s the point?

As a project continues, the software used

becomes more robust and complex

No project can use a single software platform

All programs have their strengths and

weaknesses

Master 2 platforms that are most important for

your industry or interests

Be aware of the rest!

The Software of BIM



Tonight‟s agenda

31

4 distinct areas to

address for

implementation

Technical issues

Organizational issues

Process issues

Policy issues

Obstacles for BIM

Technical Issues

Cost of

Hardware

Software

Availability of Skilled workers

Training Investment

Experience required

Will improve with time

Increased adoption in the market place

32

Process Issues

Getting past legacy methods

Teaching old dogs new tricks

Discovering new best practices

Industry and firm specific

Design/Construction paradigm

Schedule

Deliverable expectations

Contract language

33

Organizational Issues

34

Aiming to do the minimum required by govt.

Concern over

Cost of implementation?

How will the drawings look?

“Just get it out now and we will deal with it

later…”

Organizational Issues

35

Solutions in:

Government and client mandate

Changes in contractual obligation and

project schedule

Your ability to communicate

the benefits!

Policy Issues

Is the government ready?

Are they doing it „Right‟?

BCA BIM Submission

Deliverables expectations

Statutory requirements for documentation

LTA Requirements

Development of reasonable standards

CP-83 for BIM?

How far should the standards go?

36

BIM Does not exist in a Vacuum
