SORRY FOR….

…bad English

…proverbs

…spelling errors in this presentation

…rude language

…sarcastic jokes (when in doubt: it was sarcasm)

…giving an opinion about the quality of your questions.…

…and all the other stuff (caravans, bicycles, other coaches, etc..)

But thanks for having me here!

ON THE BIM SIDE…

Core team of 8 BIM experts (broad spectrum)

Second ring of 10 – 15 part time BIM related experts

Additional special departments for energy, health, safety, etc.

Great BIM track record:

First reference of ‘BIM’ in publication (1992)

BIM Handbook in 1988 (!)

Worked on IFC since beginning

Involved on several levels

at BuildingSMART


HOW ABOUT YOU?

Architects?

Engineers?

Contractors?

BIM Managers?

Policy makers?

Modellers?

Managers?

Are you ready for controversial statements?


START WITH THE CONCLUSIONS:

Collaboration is not the same as data sharing

You need to know what (and how) you / the other person need(s)

Domain models are the master models

It is not about a theoretical perfect BIM


LET’S START AT THE BEGINNING…..


1998 (?)


“SHARED DATA MODEL”

shared

data

model

COMMON MISCONCEPTION:

Shared data model is NOT equal to:

Shared data(base)

Shared BIM model instance

Shared data model comes from the need to share/distribute data in a

standardized way…. “let’s agree this is a door”

shared data model == creating agreements (interoperability)

BIM DATA FLOW THROUGH STANDARDS:

REDUCING INTERFACES

YES, I’VE SEEN THE PICTURES…

RELEASE


2010/11: NATIONAL BIMSERVER PILOT


2012: REPORT


THE PILOT / RESEARCH

Look at how information flows in a project

Look at how which tools are used

Research: compare ‘homogeneous’ software with ‘own choice’ software


“THERE IS NO CENTRAL MODEL”

(IN A PROJECT)

DENMARK 2006:

DENMARK 2008:

NL 2012:

NO ROUNDTRIP(import/export in a chain of tools)

OBSERVATIONS:

“There is no loss of data using IFC”… It is all in the native software. The

question is what data you want to share (using IFC). What data do you need

to do your job? Then we look if that is in IFC (and in your tool after import)

Not a single IFC ‘loss of data’-issue occurred during the experiments.

In a homogeneous software environment, users felt that all team members

should have equal BIM software modeling expertise. When using the

concept of reference models, not all project team members collaborating in a

project need to have the same level of BIM expertise.

34

AND TO CLOSE UP….

The use of a reference model concept with IFC can lower the needed BIM

competences for a project partner to be able to collaborate in a way that is

sufficiently effective for the entire project team.

All respondents in this experiment were strongly convinced that choosing

project partners based on their competence of a specific software tool,

prior to their engineering competence, is never preferred

35

FOUND CONCLUSION:

WORKING (LIVE) IN A ‘CENTRAL’

MODELSERVER HAS MORE

DOWNSIDES THAN ADVANTAGES.

(OWNERSHIP OF OBJECTS, LEGAL ASPECTS,

BIM MANAGER, CHANGE REQUESTS, ETC...)

36

BIMSERVER TODAY:

IN THE MEANTIME….


STATE OF BIM COLLABORATION IN 2015

Working with ‘Reference model concept’ is the norm

Main input for BuildingSMART International IFC4 Referenceview MVD

Working with IFC is like sliced bread

Reference model concept is integral part of National BIM Guidelines

IFC usage and understanding has rapidly grown

Making a BIM is not the goal

Collaboration is seen as something else than just sharing data!


“A CENTRAL DATASTORE

STIMULATES WRONG BEHAVIOUR”

EVERYONE BRINGS THEIR

CRAFTSMANSHIP AND EXPERTISE

TO ACTUALLY COLLABORATE

THE REAL QUESTIONS ARE:

- WHAT DO I NEED TO DO MY JOB?

- WHAT DO OTHERS NEED FROM ME TO DO THEIRS?

SOME EXAMPLES


EXAMPLE: SEVERAL MODELING TOOLS

Several modelling tools used

All sharing parts of the model as IFC

Quality checks

Filtering objects to create a new view

For good coordination you still need to know who created what object

So even in a single database you still have separate models….


EXAMPLE: CONTRACTOR USING

SUPPLIER MODELS

Architectural and Construction model as a base

Suppliers deliver IFC models to replace original model parts


This is an animation in the original presentation…

Want it? E-mail me on [email protected]

EXAMPLE:

COMPARE DESIGN / ENGINEERING

Contractor and lime stone supplier

Comparing models


EXAMPLE: 3 IFC EXPORTS FROM 1 MODEL

Because that is what collaboration is about!


IFC Coordination view

IFC 2nd order space boundaries

IFC explicit geometry

EXAMPLE: VOIDS

Exchange openings

Openings are not a lack of data; they are there. Some people need them.

HOW TO GET THE DATA FLOWING…..


BIM EXECUTION PLANS / PROTOCOLS

DO NOT WORK


THE REAL QUESTIONS ARE:

- WHAT DO I NEED TO DO MY JOB?

- WHAT DO OTHERS NEED FROM ME TO DO THEIRS?

2014: BIM PROTOCOL GENERATOR


http://bimprotocolgenerator.com/

BIM PROTOCOL GENERATOR

Ask others about their preferred way of working

What data do you need to do your job?

How do you want it?

What tools do you use? And what data structures?

Protocol generator merges the answers to a concept protocol.

Team discusses the issues and transforms it to final protocol.

“Protocol generator is a team building machine”


COLLABORATION: FORGET ABOUT

THE BLACK BOX!

BEWARE OF THE GATEKEEPER

LESSONS LEARNED

Don’t fight fragmentation; embrace it

Domain/discipline models are the master models

Collaboration is not the same as data sharing

You need to know what (and how) the other person needs

You need to know what yóu need from others

It is not about a theoretical perfect BIM
