In this paper, we describe how to use AR to support monitoring and documentation of construction site progress. We present an approach that uses aerial 3-D reconstruction to automatically capture progress information and a mobile AR client for on-site visualisation. We describe in detail how to capture 3-D, how to register the AR system within the physical outdoor environment, how to visualise progress information in a comprehensible way in an AR overlay, and how to interact with this kind of information. By implementing such an AR system, we are able to provide an overview about the possibilities and future applications of AR in the construction industry.
