In recent years, nuclear power plant construction sites have faced challenges such as labor shortages and constraints on working hours, creating a strong demand for improved productivity through the use of digital technologies. In this initiative, we focused on the inspection of embedded plates installed during construction and developed an on-site inspection rationalization system utilizing Mixed Reality (MR) technology.
Compared with conventional visual inspections performed by workers, this system achieves shorter inspection times and improved inspection accuracy, thereby contributing to reduced risks of construction schedule delays and rework costs caused by overlooked discrepancies.
By utilizing MR software and devices, design drawings are overlaid and displayed on site. This enables intuitive verification of consistency between the construction status and the drawings.
Because the projected drawings can be immediately compared with the actual construction status, inspection time is reduced compared with conventional visual checks. Double-checking of projection records contributes to reducing the risk of overlooking discrepancies with the drawings. Even when installation deviations of embedded hardware are identified, the results can be timely reflected in structural designs such as piping supports.
