Professional/Chartered Surveyors work with precise electronic measuring systems, lasers, surveying instruments and computers - the data must be collected as precisely as possible. In the office they are then processed electronically for the Registry Office for real estate or for the amendments of plans, etc. The projects surveyors work on are highly diverse: from bridge building to draining projects, land planning and all types of building. They are employed by building companies, private surveyor consultancies or official surveying authorities.
