Description

 Ministry of Land, Infrastructure, Transport and Tourism (MLIT) in Japan is promoting the intelligent construction for productivity improvement, quality assurance, and cost reduction. In the intelligent construction, as-built management using Total Station (TS) is conducted. In this situation, a three-dimensional design data is manually created based on a two-dimensional drawing. And this puts a burden to contractors. Therefore, it is necessary to create a three-dimensional design data automatically. In order to solve this problem, there is a three-dimensional polyline utilized in Machine Control and Machine Guidance (MC/MG). This polyline data has the information required to create a three-dimensional design data. In addition, there are sites where MC/MG is combined with as-built management using TS. Therefore, if a three-dimensional design data is automatically created using a three-dimensional polyline, it could reduce the time and cost to create it.<br> In this research, a system of generating three-dimensional design data based on three-dimensional polyline was developed. And we verified feasibility in the actual construction site.
