It is very difficult and also challenging to fulfill a survey application inside an industrial facility. The complex piping and mechanological equipments as also the tough environment - time schedules and the constant needs for updating drawing databases lead the usage of scanning technology as a contemporary necessity. METRICA S.A. has the ability to provide 3D measurements, as build drawings and fitting verification of 3D CAD design inside an existing installation. From scan data, we can proceed to a detailed 3D modelling and BIM production of the infrastructure as also to reverse engineer of assemblies. The accurate and complete survey is accomplished with 3D Laser Scanner and Industrial Total Stations that reduces to 1/10 the conventional measuring procedure.
