Thanks to modern technology, we can now use a current image of the facility in several types of software for documenting, planning, and designing various phases of a project. Laser scanning measures accurately with millimetre precision. The scanner is set up on a stand and first photographs in 360° and then measures millions of points within a few minutes. When the measurement is complete, the scanner is moved to a new position to add new measurement points and render a complete measurement of the facility. Laser scanning of a smaller heating facility or industrial space usually only takes a day or two.
