In this work, we present a system combining modern 3D reconstruction technologies with a wireless sensor network for remote monitoring and information management of construction sites. After describing the most important requirements, we compare available technologies and present our implementation of a prototype system and its capabilities as a baseline for future applications.

For on-site data transmission (e.g. sensor data), we implemented a sub-1-GHz wireless network utilizing the CC1350 Simplelink, an ultra-low-power wireless micro controller manufactured by Texas Instruments. Offline local data access is supported and demonstrated by our Android application for reading and modifying data on each node via direct Bluetooth connection. Additionally, information among nodes, connected devices, and a remote server, is transmitted via a gateway over the Internet. We leverage the capabilities of the Microsoft HoloLens to provide augmented information and to create an up-to-date 3D scan of the environment on-site. The 3D model and node data is provided to remote observers in real time using our visualization client.
