• BIM—Building Information Modeling

• Definition by American national BIM standards association:

- Digital expression of a construction project.

- A shared resource: provides a reliable basis for all

decisions during the entire life cycle of the facility from

construction to removal.

- At different stages of the project, different roles insert,

extract, update and modify information in BIM to support

and reflect their respective responsibilities in the

collaborative work.

Standard

Entire Life Cycle Process

• Plan：Planning Institute；

• Design：Design institutes of architecture,

transportation, water conservancy and

electric power；

• Construction ：construction company，

such as: intelligent construction

management platform;

• Maintenance ：the earliest BIM+GIS

application, such as Shanghai Tower.

The

Deficiency

of BIM

Application

Focus on monomer, lack of macro.BIM focuses on the management of the whole life

cycle of buildings and lacks the surrounding macro

geographical environment.

How to deliver BIM data whose format is not uniform?There are many kinds of BIM modeling software and the data format is inconsistent.

After the completion of construc-

tion, how will BIM play its role in

the maintenance stage?Focus on design, construction, lack of late

operation and maintenance management.

• Planning Stage

– Site analysis, planning approval, project demonstration, etc

• Design Stage

– Less GIS participate in

• Construction Stage

– Construction schedule simulation, construction organization simulation, etc

• Maintenance Stage

– Delivery completion model, maintenance plan ,asset management, disaster emergency simulation etc
