As a result of the rapid advance of information technology (IT) and development of CALS/EC in recent years, the MLIT (Ministry of Land, Infrastructure and Transport) and other organizations that order public works projects now deliver the results of survey and design work and completed work drawings as electronic data and can now directly handle information related to construction projects as electronic data. Of these, work at the maintenance stage is expected to benefit the most from the use of electronic information because it permits the collection of preliminary study, surveying, design, and execution information. And although GIS and other data bases are being constructed, data bases that have been construction and operated up till now have been constructed as separate systems that cannot share and link their information. Linking data bases is counted on to permit integrated handling of their information and linked searching and bloc updating of the data bases to increase their effectiveness among the project groups that have systems.

This report describes rules applied to share and link information in different databases so that their users can exchange their data and thereby synergistically receive the benefits of the electronic handling of information. It also discusses the effects of linking information by comparing present and future conditions based on a work process analysis.
