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…
