BIM : Tools or processes ?
Processes and/then tools
As part of the contract and the project management plan
Processes need to be defined
C. Castaing
Then tools need to be implemented, including workflow and data management
The BIM exploitation guide
( BS or ISO, etc…)
From buildings to urban infrastructures
A - a technical requirement to measure resilience: the building needs to be developed in its context:
- the site
- the city
C. Castaing
- the systems
B- an economical reason :
the market of the next infrastructures is massively
urban
CIM instead of BIM
For 100 pieces of information/exchange to be
managed during the full life cycle:
� 5 to be managed during the initial design phase ( BIM)
� 20 to be managed during the construction phase
C. Castaing
� 20 to be managed during the construction phase (BAM)
� 75 to be managed during the operation phase ( BOOM)
Construction Information Management ( JACIC from Japan) seems a relevant name for the process
Smart construction and smart citiesTwo examples coming from a road/or a street
for the next 10 years
A - the pavement is not only
- a structure for vehicle traffic
- But a structure to embed the
smart city systems
C. Castaing
B - the pavement as a smart
construction:
the information related to the
maintenance, traffic, etc… are
embedded within structural objects
Sensor for
traffic
Measurement
Impact on BIM: from operation to design
A- The construction ( asset) is a 3D
model of real objects storing its
own information (as a real data
bank)
C. Castaing
B- The BIM is a mirror (avatar) of the
asset to display and to manage the
information set at the design stageRoad memory

The BIM approach for a smart and sustainable city
A- the City information modelling to interact on the urban morphology
B- the urban morphology proposes a model based on :
• Domains
• Systems
C. Castaing
• Systems
• components
C- the model provides tools to verify how the smart city is able to
react to the context ( ex: weather modifications):• facades can be modified with a remote control
• street lanes can be closed with a remote control
