Appreciation for your cooperation with ISARC2020

Amidst the corona crisis, it became necessary to hold the ISARC symposium online this year. This was the first time for ISARC to be held online. In spite of our worries about troubles that might arise due to communication problems and time zone differences, we were able to complete the conference successfully thanks to the great cooperation of the participants and IAARC. We would like to express our sincere appreciation to all the people who were involved in organizing and managing this online symposium.
The next symposium is scheduled to be held next year in Dubai, UAE. We anticipate your continued effort and support in the development of automation and robotics in construction.

This paper presented an innovative composite structure, with an outer part laminated with mortar exclusively for 3D printers and an inner part filled with ultra-high strength fiber-reinforced concrete as a substitute of reinforcing bars. A 7-meter long shell-shaped bench was successfully manufactured using this composite material as well as topology optimization, which would have been difficult to construct with a formwork.

Digital Twinning of Railway Overhead Line Equipment from Airborne LiDAR Data

Department of Engineering, University of Cambridge, United Kingdom

This paper presented a novel method to generate the Digital Twin of Overhead Line Equipment (OLE) system in existing railways from point clouds. When tested on a challenging case of 18 km railway, the method achieved overall detection rates of 93.2% F1 score for OLE cables and 98.1% F1 score for other OLE elements.
