Consideration about an application possibility of the CIM to upkeeping of a concrete structure

Takumi SHIMOMURA

Construction Information Modeling (CIM) is a new system used to represent actual structures in 3D giving the user the ability to manage them.
Nowadays, CIM systems are extensively used for design and construction, but the use of this programs has not been considered for maintenance purposes. With a CIM system it is possible to manage the structure design process and manage data during construction.
Because of this, the purpose of this research is to propose an effective way to apply CIM for maintenance purposes of concrete structures. In order to propose an effective maintenance management technique for concrete structures, the CIM system was modified to fit maintenance of a real structure and its applicability was evaluated. In order to apply CIM techniques to the maintenance process, a system which considers collective structure management system and an analysis program for structure prediction is needed. Therefore, a new CIM system which considered this two conditions was generated. Also a three-dimensional model was made and results from analysis were indicated.
There are two functions added to this system, a map used to give the location of maintenance management structures in the system, and as a function of CIM, three-dimensional model of the structure and its topography are available. Additionally, the system allows the user to edit the structure model easily and an option to prepare weather and topographic data automatically were added to make the analysis easier.
This functions were applied to represent salt penetration on a real structure using the developed system. Results of the analysis demonstrated the ability of using CIM techniques for prediction purposes in maintenance management.
