Control measurement and 3D scanning of buildings and objects

One way to improve the situation is to take an on-site inventory based on the existing drawings. In particular, the scope and disposition of spaces can be checked, but the measurements of both the entire building and of each space can also be checked.

With modern 3D scanning technology, the reality of the objects can also be measured using 3D scanning, which actually makes it possible to create new drawings directly based on the results of the scan. This method is a bit more expensive, but far more efficient.

Modern 3D scanners measure and record the actual appearance of a building with great accuracy. It is possible to scan both the outside and inside by tying together the points from which the measurement is taken. Since the scanner takes pictures of reality, a CAD operator can create drawings based on a complex point cloud in 3D with great accuracy.

This is a modern and effective method to prevent inaccurate drawings, which probably do not represent reality anyway, and could jeopardize the digitization project. However, the use of 3D scanners is a more time-consuming process, which makes it a more expensive option.

A somewhat less expensive option is to carry out control measurements of objects for which there are no drawings, or where the information needs to be checked. Other measurable structural objects such as pillars, elevator shafts or stairways can also be measured when necessary. The measurement points taken form a measurement chain that can be transferred to the drawing, where important weight-bearing building components are linked together. The aim is to improve the quality of the drawing documentation regarding measurement accuracy, not to achieve comprehensive accuracy for each interior detail.
