Benefits of CIM (Construction Information Management)

Compared the two-dimensional CAD and 3D product model

• Two-dimensional drawings : If civil engineer look the data(drawings),

he recognize and imagine the object.

• However, two-dimensional CAD is, mere "line", "curves and circle", a

collection of "character", "pattern data".

• It’s difficult to recognize the members to the computer.

• For 3D product model, based on object-oriented technology to

represent a member shape and attribute data in a text file that is

compatible.

• As a result, the data of 3D product model, the computer can

understand.

SAMPLE USAGE OF THE

ACTUAL CONSTRUCTION

Water resources utilization facility

• The structure information such as to be

buried using the aggregation maintains

the 3D model.

• In conjunction with local sensors (such

as an IC tag), the behavior can be easy to

understand.

• Inspection and maintenance history helps

to update plan.

Tunnel construction

• Product model manage the observation

information, the measurement information,

and feedback in the 3D model.

• The model have implemented the centralized

management of construction information.

• Since lining quality information such as

concrete also saved and can be used as a

maintenance model after completion.

CIM CHALLENGES

Fumbling situation with respect to CIM: construction of BIM initiatives

serve as a reference

However, civil engineering specific order form

In the short term, the "construction BIM"

And consider the medium- and

long-term to the data available in

consideration of the cooperation?

(Relationship, such as the right figure)

The current design and construction

will change

(Partially) design build?
