A Nagoya Underground Mall Measured by FARO Laser Scanner

shopping malls might be demolished in future to make way for further development, In order to preserve this piece of history Station Square on the western side of Japan Railway Nagoya Station

Scanning in 17 Locations at Midnight Late night scanning that begin from the exits of the underground shopping mall.

Adding to the point cloud data of the underground mall, the team created 3D models of the water supply, sewerage pipes, and manholes.

Providing a Laser Scanning Solution

Point cloud data of the railway platform.

As the Government contemplates doubling existing railway lines, the research results will influence future railway infrastructure strategies for India.

SIPPR Engineering Group Co., Ltd

Applications • Digital modeling of factory site • Retrofit of factory equipment, and pipeline • Engineering calculations

Benefits • Improved work efficiency • Accurate data collection • Wide-ranging engineering applicability with BIM technology

With increasing technological advancements to 3D laser scanning and (BIM), AEC industry is witnessing a scientific and technological revolution since the introduction of CAD. One notable application is the deployment of 3D laser scanning to measure any complex construction environment – regardless which stage a project is at.

TOZ Group: Measurement Challenges

Company plans, designs, and operates collaborative spaces to optimize the co-working experience.

Challenge to survey more than 100 buildings each year. TOZ manually measured working spaces using laser rulers and measuring tapes, the manual process frequently recorded inaccurate measurements. TOZ got into a disagreement with a building owner due to measurement errors

Benefits • 80% decrease in the error rate • 50% reduction in the survey time
