I worked on a nuclear energy project during my time as an esri UK consultant during the preconstruction phase. I created an ArcGIS Hub site and various ArcGIS Online applications and surveys for such as bat surveys using Survey123 for ecologists and equipment mapping and status dashboards for groundworks contractors using (before the time of Experience Builder) an ArcGIS webmap embedded within a ArcGIS Online dashboard.

Data security and permissions management was crucial and layers, maps and apps all had specific privileges and/or view layers created so only those permitted could see attributes and metadata and have access to certain digital items.
