ABSTRACT
As part of the PROGRESS research project a steel-based single-story hall was deconstructed and the primary and secondary structure of the building was recovered. The structure was explored by UAV devices. The SSH is built of 7 different parts. From up to down the hall consists of the roof insulation build out of Styrofoam with a foil, the roof itself made of trapezoidal sheets, a secondary steel structure connected to the primary arcs. The steel-based construction is founded on a reinforced concrete plate. The plate and fundaments are located ca. 1,0m above the ground. The space in between is filled with sand or any other material suitable at the original building time. Exploring materials and even chemical tests of mineral waste is common and important due to the risk to contaminate the environment or risk health of people. To create drawings of buildings to demolish or dismantle is not worth the effort. Nevertheless, exact geometry knowledge is very helpful for the planning of a demolition project and was rebuild by the use of UAV devices. A technique was developed to perform the deconstruction for reuse of steel parts mainly by excavators. Thus, the recovering of usable parts and the demolition of the concrete based ground plate was performed by the same machines. This paper presents the results and discusses the possibilities of excavator-based deconstruction.
