Laser scanning in tunnels and shafts
The maintenance of underground facilities will generally involve the temporary closure of the structure concerned.
In many cases, the speed of service of a contractor will be a decision-making factor for the operators of road or rail tunnels, service tunnels, bridges or caves which are accessible to the public.
The recording of surveys and the production of plans (in advance of maintenance) will be bound by the same requirements; this is the revolutionary aspect of dimensional surveys by 3D laser scanning: a given environment can be surveyed through 360° at high speed, allowing a virtual tour of the facility concerned to be taken thereafter ... at the visitor's leisure.
