"Since 1983, Ministry of Construction has been engaged in the research project ""Development of Advanced Systems for Construction Technologies with Proper Use of Electronics"". This project has the purpose of making contribution to improve construction technologies related to planning, design, execution, maintenance and conservation by application of the electronics-related technologies. Building Research Institute researched in architecture field and Public Works Research Institute researched in the other construction field. The results of this project done by Public Works Research Institute are as follows: 1) Advanced systems for construction of tunnel, dam, bridge, pavement, etc. are designed conceptually. 2) Specifications of highly advanced construction equipments are proposed. 3) Some technologies for automatization of bulldozer and compacting equipment are developed. 4) Digital photogrammetric system is developed and applied to construction management of large-scale earthworks. 5) Construction information database system is developed.
