III/ CONCLUSION

We live in a moving

world

The way of communicatinginformation has greatly evolved

Written words 3500BC (Mesopotamia)

Paper printing700BC (China)

E-mail1971 (USA)

Printing press1436 (Germany)

Instant messaging1980 (USA)

Fax1960 (USA)

Today, new tools appear and still revolutionized

the way we share information

... And they affect all fields

if they want to continue to be profitable

Companies of the construction field must

follow this evolution

But today, this sector is far from being the most innovative

“The construction industry

is among the least digitized”

If you want to continue to be competitive…

questions3You must ask yourself

Why change ?

Why innovation ?

Why data

management ?

The BIM is part of the answer !

1st question

Why do we

need change in

field today?

CONSTRUCTION

Imperfections in the construction field are numerous

12%

5%

Of the construction materials are wasted

Accidents absorb

Of the potential of the working forces is

used

<50%

At least

Of total projectcost

< 5%10%

< 3%

Projects on time and on budget

Of net margin

Of failure costs

« Construction remains a very inefficient industry

wastage, miscommunication, lack of information »

WASTES

RISKS

And so many improvements are still possible:

2nd question

WhyShould we innovate ?

INNOVATE

or …

BECAUSE

« Don’t be afraid to fail… … be afraid not to try! »

And in which field ?

Data Management

• 3D scanning• 3D printing

• Standardisation• Knowledge management • Document management /

archiving• Mail management

• Tablets• Central database• QR Code• RFID (Radio Frequency

IDentification)

3rd question

WHY data management ?

[Data Management]

“Centralization of coordinated information for reuse

directly / trough different softwares & assets”

In the construction field

A changing sector

Construction is

The numberOf complex & integrated contracts increases

1. Difficult coordination with extensive loss of resources

2. Decisions are made too late (after design)

3. Inaccurate estimates

4. Errors/problems are realised too late

5. Lack of visual information

To avoid the shortcomings of traditional methods

Why data management ?

1. Meeting schedule

2. Keeping within budget

3. Delivering quality of work

To succeed the challenges often encountered

Why data management ?

Why data management ?

How to get data from the right parties at the right time ?

How to get usable information ?

How to manage changes throughout the project?

To provide correct answers of daily concerns

Now, let’s talk about

Why the BIM ?

A logical answer

“Build it digitally before physically” !

Why the BIM ?

“ To centralize information, enable integral

engineering and share coordinated data“

Basically,

What is BIM ?

Now

[Building Information Modelling]

“It is a process of generating and managing

building data during its whole life-cycle”

What is BIM ?

More than 3D modelling

And use a Central data base

BIM is

Building Information Model

Building Information Modelling

Building Information Management

There are many ways to understand the BIM

This (r-)evolutionizes the traditional method

Thousands drawings one BIM modelfrom to

As one often think, BIM IS NOT

• A complex software

• A simple 3D model

• A nested market

• A new tech company

• …

It’s a NEED !

BIM ICEBERG

What is seen

What is hidden

It's a COLLABORATIVE PROCESS

1. Working on common fully informed models

2. Using integrated and interoperable software

3. Following workflows and a clearly defined process

4. Involving the coordination of experienced people

Models Software Process People

In this process, data is

INCREMENTED & CAPITALIZED (rather than entering by each contributors)

Then, CHECKED and OPERATED at each stage in function of the needs

“Elements have properties that can be accessed by functions”

BIM

• location line• bottom/top level• length• thickness• creation phase• demolition phase• mark• comment• material(s)• manufacturer• cost...

CAD

• geometrical description

With these software, we can encode an infinity of data

which will be attached to the 3D elements of our models

Therefore, the exploitation of this data leads to a widerange of applications throughout the whole building's life cycle

There will always be a main software that will be most often used

and in which the majority of the data will be encoded

The design conception software

But do not forget that

each type of tools has specific goals according to the needs

ConceptionModel Checking

MEP Energy 4D SimulationStructureFacility Management

Calculation

Examples of uses

Depending on the features of the tools used,we speak about different BIM levels or BIM dimensions

In practice, for the BIM to be a reality, there are some essential conditions

1. Interoperability of the software used

2. A contract with all workflows and requirements (The BIM Management Plan)

3. The involvement of all stakeholders & members of the teams (not only the BIM Manager)

4. Continuous training

5. Used at each stages of the project

6. Efficient hardware and informatics software.

BIM GOALS

As a global process, BIM has

many objectives & consequences,

according to its many fields of applications.

General Objectives of BIM

1. Optimize costs through all the process:

• Set earlier technical solutions at design stage

• Decrease modifications at construction stage

• Enable effective facility management at operation stage

Better visualization, more data better

organized, greater Level Of Detail

Build it digitally before physically

Capitalized, organized

and interoperable data

BIM

2. Increase & accelerate collaboration between all stakeholders

From the design team to the FM team

General Objectives of BIM

3. Test, analyze, simulate and calculate more easily

With a very knowledgeable and sharable model.

General Objectives of BIM

More generally, the ideal objective of the BIM is to reduce or

to overcome the recurring issues in the construction field

Wastes

Accidents

Miscommunication

Delays

Modifications

Inaccuracy

Lack of information

Modifications

“Collaborate to build better,

document to use better.”

Why using BIM at ?

Originally, the implantation of BIM at Besix

was a real necessity rather than a desire

There are several reasons for this:

1. On the one hand, to meet the growing demand of our customers throughout the world

2. To remain competitive in a difficult context

3. By offering a range of innovative services equivalent to those of our competitors

4. To follow the natural evolution of the construction market

5. And above all, to improve our profitability on many aspects

Why using BIM at ?

“If you are not the Early adopter,

be at least the Best follower”

Here are some difficulties we encountered

- 43 %Reduction of our profit over the last 15 years

<5%Projects completed in time & budget

x6The probability to be awarded by proposing this process

during tendering has been multiplicated

But gradually, by adopting the BIM,

80€ vs 1000$The cost of solving a clash in BIM is cheaper than on site.

The development of the BIM at was done in steps.

With cycles of about 2 years
