Development of construction quality management technology for intelligent road infrastructure

(Co-PI, KRW 4,681,900,000), 2020-2025

This project proposes to develop efficiency & quality improvement technologies for construction of prefab-based road structures using shape measurement technology. This project will include 1) development of system that enables decision making of constructability of prefab structures during construction based on as-is shapes of the structures, 2) structural integrity and construction quality monitoring technology during transportation, and 3) development of standard guidelines for construction quality monitoring and management system

Experiencing construction site visit in classroom

(PI, KRW 10,000,000), 2020-2021

This project proposes to use 360 cameras to acquire key information of construction site environments and spatiotemporal processes and activities. This project will include the development of a web-based digital platform providing multiple functions that students can exploit to obtaining the construction knowledge in an effective and active manner. it is expected that this project can help current construction education to move away from a teacher-centered learning process into a more collaborative student-centered one.

Development of Automated Formwork and Rebar Inspection Technology for RC Structures using Laser Scanning (PI, KRW 30,000,000), 2020-2021

This study aims to develop a TLS based end-to-end technique that automatically and simultaneously assesses the primary dimensional quality checklists for formwork and rebar. To this end, machine-learning and AI methodologies are applied and further investigated to enhance the inspection efficiency and accuracy.
