DEVELOPMENT OF A PROTOTYPE OF ROAD DESIGN CHECK SYSTEM UTILIZING 3D MODEL

Abstract

 Many cases of errors related to the design deliverables of construction consultants have been reported. The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) has made red-yellow checking (verification for consistency) mandatory in detailed design, and the Japan Civil engineering Consultants Association (JCCA) has strengthened verification and checklists, but these measures have not yet eliminated all errors. In addition, human verification according to the verification guidelines has become a great burden. In this paper, a prototype of a road design check system utilizing 3D models is developed in order to improve productivity by reliably eliminating design errors and improving verification efficiency. Prior to the development of the system, 185 cases of errors in road design deliverables were analyzed, and it was confirmed that almost all errors could be eliminated by using 3D models.
