The construction sector has a long record of poor performances…
Productivity in manufacturing has nearly doubled whereas in the construction
sector it has remained flat (and in some areas has even dropped)
3
Or in a more qualitative approach…
4
The built environment (all human-made space in which people live, work,
and recreate) strongly affects the economic, environmental and social
development as a whole…
It needs to be:
• Healthy
• Comfortable
• Safe
• Affordable
• Flexible
• Sustainable
• …
…but it‘s not only about productivity
5
Digitalization of the construction sector is increasingly recognized as a potential game changer for the sector
5
IT spendings in construction do not exceed 1% and only agriculture
and hunting seem to spend less…

8 actions :• Secure order and BIM contracts
• Simplify control and autocontrols of construction projects
• Standardization
• National Observatory of the digital in construction sector
• Develop user friendly learning tools
• Measure its BIM maturity
• Create an dynamic ecosystem allowing all the actors to discuss and exchange on a local scale
• Push the development of the national BIM platform : Kroqi

BIM Collaborative platform for SME
Global aims
• to promote the development of adapted tools
(for sme)
• To develop a trusted digital ecosystem
• To promote open Standardization
3 main objectives
• Avoid the digital gap between SMEs (85% of the
construction sector) and other stakeholders
• Answer the needs of professionals :
simplicity, reliability, security
• Initiate a dedicated digital marketplace with start-ups
and software vendors

Code checking
Aim
New automated ways for code checking that are BIM compliant
Innovative means to express regulations in the future
15
Overview of the diversity of regulatory documents
A large and heterogeneous set of documents- Codes / Standards / Eurocodes / Calculation methods / Professional Rules /
Guides
- Different structures / different « customs » or habits -> different vocabularies

Example of the transformation process(fire safety)
Establishments wholly occupying the building with the lowest
floor of the highest storey located more than 8 meters from the
access level of the fire brigade shall have a 1-hour fire-resistant
structure and fire-rated floors of the same degree.
