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.

Goal of ‘CIM’
・Data exchange and
linkage between
application
・Use to maintenance

ICT 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.

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?
