Why BIM?
4
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
“Data structure with data fields and methods”Elements have properties that can be accessed by functions

BIM during hand over
Construction Field Management Software
• Consult latest drawings at any time and place• Capture and manage handover remarks
locate, illustrate, assign, close
• Respect workflow• Dashboard overview• Reporting across business units
� Time savings and increased quality� Integration with BIM models possible

55
Room by room
• Information of finishes, doors and equipment per room
• tender and pre execution: check of architectural program completeness
• execution: support procurement, scope definition subcontractor, quantify variation orders, progress reports
• support snag list generation during hand over
• � possible link with 3D BIM model

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

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!
