Research on the Extendable Data Exchange Standard in Information Integrated Construction of Filling Work

Efforts to promote the information integrated construction of civil engineering work include the study and development of systems for efficiently conducting work and saving labor. However, such systems are often designed for a specific construction site or machinery, so construction information cannot be fully applied to other work sites or construction machinery. It is very important to realize sharing and linking of construction information throughout a CALS (Continuous Acquisition and Life-cycle Support)-based lifecycle, however there is insufficient sharing and linking in the construction stage, especially in the stage before and after the construction. In our research, in order to efficiently complete information integrated construction with sharing and linking of construction information, we proposed an extendible data exchange standard (DES) for filling work, and introduced its review procedure. At last, the requirements of conversion software with efficiently exchanging data by utilizing the DES are summarized.

CAD Data Identity Determination Component — Logical Smart —

In the CAD drawing standard of the Ministry of Land, Infrastructure and Transport, it is clearly written that the CAD drawing’s exchange format will conform to the international standard ISO10303-202 (STEP/AP202). On the other hand, at the Japan Construction Information Center’s (JACIC) CAD Data Exchange Standard Development Consortium (SCADEC: Standard CAD data exchange format in japanese Construction field), exchange format (SXF:SCADEC eXchange Format) based on STEP/AP202 was developed. In the future, for the electronic delivery of CAD data related to construction, SXF will be adopted. In addition, in Osaka Prefecture, securing CAD data related to construction is raised as an issue for electronic delivery system/information sharing system. However, in the current situation, system that can distinguish identity of 2 distinct CAD data does not exist. For this reason, in this research, a system, specifically called Logical Smart, that determines the identity of CAD data by using SXF is developed.
