This document discusses challenges and opportunities related to implementing Building Information Modeling (BIM) within an organization. It provides examples of BIM projects including clash detection, visualizations, and quantity take-offs. Key challenges discussed are expanding BIM expertise across more teams and disciplines, addressing legal issues when sharing models, and changing practices to involve subcontractors earlier. The document emphasizes that successful BIM implementation requires focusing on people, processes, and tools, not just software. It also recommends taking incremental steps to adopt BIM and being opportunistic to find applications that drive early adoption.

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

63. • 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?
63

64. 64

65. • Formalize information flow on traditional projects
• Map generic BIM deployment plan on each major
information exchange

67. (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
67

68. (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
68

69. Challenges and difficulties
69

70. 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…)
70

71. 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
71

72. 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…
72

73. 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
73

74. Difficulties
• collaboration with rest of ‘traditional CAD’ technical office
BIM 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!
74

75. Attention points during BIM
implementation
75

76. Tools
Procceses
People
Do not only focus on software and hardware
76

77. People
• Clear career path
• Permanent training at every level
• Train on ‘real’ projects and not on school examples
• Stimulate self learning
• Do not hesitate to train entire supply chain
77

78. • Project: BIM protocol/deployment plan is essential.
Contractual/financial part is often forgotten
• Be opportunistic: commercial/visual applications are often the
entrance door
• Analyse before you optimize. Understand your environment and
adapt BIM to it. Tailor made BIM!
• Implement in steps
2D  3D  4D  5D
design dpt  tender dpt  planning dpt.  construction site
78

79. • Keep developments compatible
BIM – Systems Engineering – Tablets
• Define BIM metrics – KPIs
mandays/drawing, m² modelled/manday, cost per clash, coordination cost…
• It’s a never ending story…
