Abstract
The intelligent construction system that streamlines the civil engineering through effective use of information is expected to meet needs for efficient maintenance and management of infrastructure as well as enhancement of productivity. Its application to riverbed earthwork promises a substantial benefit partly because the timeframe available for the work at river sites is restricted to the dry season and also because work progress is frequently retarded by snowfall or other elements. With a view toward betterment of excavation in riverbeds, the Hokkaido Development Bureau of the Ministry of Land Infrastructure and Transport has been discussing the application of ICT (Information and Communication Technology) to the work, starting in fiscal year 2006. Tasks assigned to basic field tests conducted by the bureau include comparison between the new and traditional technologies. Discussion over the effects to be obtained from the ICT is also made.
This paper explains standard methods for execution, work management, and work form management to be promoted by the bureau for riverbed excavation; workability already verified at test sites; and benefits that could be derived from introduction of the ICT when use is made of a backhoe loaded with 3D design data that basically allows the contractor to dispense with finishing stakes on the strength of electronic data furnished by the owner to the contractor. Simultaneously, the so-called total station is brought into play. Additionally, this paper deals with problems that still remain unsolved in relation to the application of the ICT to job sites and suggests solutions to them.
