This deliverable documents the prefabrication and pre-engineering requirements of the hybridGEOTABS (key) modules, while considering the interaction and integration of the components in the system. The efficient integration of hybridGEOTABS in all stages of the building process is discussed. Example hydraulic schemes of the concept are developed and explained, as well as generic component specifications for tendering. This project has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement No. 723649
