Laser scanning to monitor excavation progress

Data allows optimisation of construction processes and safety on the job

Example of laser scanning to monitor excavation progress

As a general trend, advances in construction monitoring are moving away from physical measurements at a limited number of points, to widely distributed, wirelessly connected sensor networks, and to areal scanning techniques. These data allow contractors to optimise construction processes and increase safety on the job.

Integrating data from multiple projects could facilitate improved equipment design, performance prediction and understanding of zonation and geologic material properties. Monitoring for enhanced safety was also becoming more critical, as larger diameter and shallower infrastructure, for example, tunnels and stations, facilities were increasingly proposed for urban sites.
