AS-BUILT MANAGEMENT METHOD USING THE EXECUTION HISTORY OF CONSTRUCTION EQUIPMENT FOR EXCAVATION / PAVEMENT CONSTRUCTION WORKS ON ROADS

Abstract

 ICT construction machinery uses under-the-machine control / machine guidance systems at construction sites to obtain log data on their movement and behavior. These data are expected to be increasingly utilized and distributed. The authors have proved in an existing study that there is a possibility that three-dimensional shapes of objects of construction works can be generated from the log data of ICT construction machinery used in road pavement construction works. Findings were also obtained that as-built management using log data can be realized if a correction method capable of calculating the pavement edge of the construction boundary can be established.

 In this study, a method for correcting log data was devised, and the existing method for generating three-dimensional shapes was improved. Then as-built management was performed as a trial in a test execution of road excavation and pavement construction, and it was proved that the improved method can be applied in practice.
