Why BIM?

A moving world…

Written words 3500BC (Mesopotamia)

Paper printing700BC (China)

E-mail1971 (USA)

Fax1960 (USA)

Printing press1436 (Germany)

Instant messaging1980 (USA)

5

And still…

Construction remains a very inefficient industrywastage, miscommunication, lack of information

Manufacturing benefits fromRepetitionFixed programControlled environment

Construction suffers fromConstant changesUnforeseen costsIncreased risks

Working forces only used at 50%of their full potential

Accidents absorb5% of total project costs

At least 10% of the construction materials are wasted

6

Challenges

• Meeting schedule• Keeping within budget• Delivering quality of work

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

How to get usable information?

How to manage changes throughout the project?

7

Shortcomings of traditional methods

• decisions are made too late (after design)

• inaccurate estimates

• errors/problems are realised too late

• difficult coordination with extensive loss of resources

• lack of visual information

8

Give-and-take

Making more accurate information and making early decisions

Building Information Modelling

“Process of generating and managing building data during its life cycle”

• more than 3D modelling• central data base

10

Modeling Objects

locate, illustrate, assign, close

• Respect workflow• Dashboard overview• Reporting across business units

� Time savings and increased quality� Integration with BIM models possible

58

Definition of BIM career paths with competence levels

at head office

in situ

Permanent training at every level

59

Challenges and difficulties

60

Future challenges• Enriching the BESIX library (CI/SfB classification system)

• Link with structural analysis

geometrical model vs. analytical model

mapping materials and profiles

• Bill of quantities

• Automatic clash detection and report

• Planning resources and cost (5D)

• BIM on site & Tablets (code bars…)

• BIM for Facility Management (equipment, room by room…)

61

Implementation difficulties

• Enlarge the team � ‘weakest’ link determines the result

more people (definition of competence levels and

career paths)

more departments

more disciplines

more training (and equipment)

• How to share/receive models? Legal liability…

format, viewer, detail level, coordinate system, exchange

platform, intellectual property issues…

• Change in practice: construction knowledge earlier in the

project

62

Implementation difficulties

• Earlier involvement of subcontractors e.g. MEP

First 3 to 6 months often in 2D since MEP, façade… come

later in the contract

• Difficulties to find subcontractors with BIM competences

(temporary situation?)

• Should the client impose BIM to us or should we impose BIM

to the client?

• Different contract type: Integrated Project Delivery?

BIG room, metrics, contracts…

63

(Inter)national initiatives

ADEB-VBA BIM working group

common BIM framework – protocol with ORI and G30 and IFMA

BIM Innovation platform

Precompetitive cooperation among European companies by

exploitation of model-based project development and execution

RevitGG

Development of Revit Standards

Building Smart

Driving open standards, tools and training in BIM for AEC and FM

64

• BIM advantages for contractors: cross trade

coordination, 4D simulations, drawing extraction…

• Requierements for BIM in execution: legal liability of

designers, phasing, object coding, cost allocation…

• Who should be BIM manager?

65G30 29/01/2015

66

• Formalize information flow on traditional

projects

• Map generic BIM deployment plan on each

major information exchange

68

(Inter)national initiatives

May 31st 2012: BIM Strategy by the UK Government

Supported by a BIM task Group

• become world leader in BIM

• 15-20% savings on the costs of capital projects

• Public construction projects will be BIM (Maturity Level 2) by

2016

69

(Inter)national initiatives

Rijksgebouwdienst (NL) = Government Building Agency

• Nov’ 2011: Rgd BIM norm imposed for all new DB(F)M(O)

contracts

• Focus on BIM for O&M (all 3D objects, space functions and

model based documentation)

• As-built documents in CAD and IFC format

EU engagement

• BIM enables European construction companies to maintain

their presence globally and promote improved performance

• EU procurement Directive is reviewing BIM

119

Challenges and difficulties

120

Difficulties

• client requires BIM but PMC is unable to judge on performed work

• hard to recruit BIM staff

• even harder to recruit BIM staff with technical expertise

• few subcontractors can deliver a model

121

Difficulties

• collaboration with rest of ‘traditional CAD’ technical officeBIM helps for highlighting clashes but does not solve them!

Coordination should be reviewed in models and not on

drawings

Share information

• software limits: file size, number of shop drawings, complex geometries…

• open standards are not (yet) perfectly reliable

• BIM is easy to blame!
