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

traffic

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
