Shop drawing production
BIM based almost 2x faster than CAD based
59
Model based quantity extraction – 76% of BOQ items • 2 to 3 times faster • Structure: 101/453 • Architecture: 1305/1687 • MEP: 2986/3631
• forecast of quantities for value engineering • quantities for erection methods • quantities for procurement • quantities for monthly statements • visual support for internal/external meetings (e.g. location of security camera’s)
Further benefits
60
(Inter)national BIM initiatives
61
(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
62
• 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
• Formalize information flow on traditional projects
• Map generic BIM deployment plan on each major
information exchange
65
66
(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
(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
Challenges and difficulties
69
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
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
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
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
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
Attention points during BIM implementation
75
Tools
Procceses
People
Do not only focus on software and hardware
76
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
• 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
• 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…
