UAVs have immense potential in construction applications. This paper gives a overview of a project that aims to expand the frontier of applications of UAVs from non-contact measurements to physically interact with buildings by sticking targets on the building. The goal of the project is to apply positioning tags onto a facade of an existing building with UAV. This paper looks into hardware, software and simulation aspects of the UAV and elaborates on advantages of the chosen solutions. Moreover, the UAV has been tested in laboratory environment.
