The application of laser scanning techniques in plant repairs Clemens Eidmann* discusses how reusing existing buildings and structures can help in the case of glass plant repairs.

new plans difficult or impossible. Furthermore, very often additions and adjustments have been made over the years so that the existing documents are no longer up to date. In these cases, it was and is common for employees of the planning company, to be on site for a longer period of time and to record the situation with conventional means, paper drawing, folding rule and laser measuring device, depending on the size of the plant. Practice shows that these inventories contain inaccuracies and can also be � The scanned system structure can be processed digitally in 2D and 3D CAD.
incomplete. A reasonable alternative to the classical inventory is the method of laser scanning, which has already been used in other areas. Sorg has now introduced laser scanning for the inventory of existing building structures and infrastructures in the glass industry. Laser scanning captures up to 1,000,000 points/second with the help of a laser beam rotating around two axes. Each detected point receives among other things two angles and a distance to the set-up laser scanner. These polar coordinates are then converted into a Cartesian coordinate system. Thus, there is an x, y, and z coordinate for each point. Furthermore, the entire system can be aligned in 3-dimensional space as desired and thus positioned to newly planned system structures in CAD programs. The Sorg laser scanning team is able to capture the complete plant situation in a short time. Therefore, the system is scanned across 400 or more installation sites of the laser scanner across all floors. The following Continued>>

xisting building structures and infrastructures and the demand for ever larger glass melting plants make the handling of so-called Brown Field projects increasingly complex. Present structures are to be reused to a larger and larger degree not only for cost reasons. The integration of new stages, entrances, plant components, etc., into the existing systems considering increasingly extensive safety regulations and the positioning of new and also reusable equipment requires a higher degree of coordination effort with the client than was necessary just a few years ago. Not only the communication with and the involvement of the customer in the solution finding process, but also the coordination of the individual technical departments over the different project phases makes a detailed visualisation of the existing plant complex necessary. For the planning and integration of the new or to be modified plant parts or infrastructures, you need to rely on existing documentation. If these are still present, they are in paper format due to the age of buildings, etc. This makes the data transfer to the
