The CTA construction project plan has three remaining phases: Pre-Construction, Pre-Production and Production. A high-level work breakdown structure is illustrated in the below figure. The diagram covers all phases of the project, but some activities (e.g. site negotiations) are only relevant to particular phases. The project office, located in Heidelberg, Germany, but moving to Bologna, Italy in early 2017, manages the overall project and systems engineering activities and is directly responsible for some deliverables, such as site infrastructure.
