The method is the same in all eighteen sectors: we start from the exchange information requirements, structure the model by discipline, coordinate it in the federated model, check it against written rules and deliver it in the required format, with the data needed by whoever will operate the asset. What changes are the sector's rules, the clients, the tools and the weight of each discipline.
On linear infrastructure the Civil 3D alignment drives everything else, and repeated elements are placed with automations. In complex buildings, such as hospitals, stations and terminals, the densest part is the building services and the coordination between disciplines. In industrial plants the coding of components matters; on existing assets the laser scanning survey comes before any model. Sixteen sectors have their own page with standards, typical deliverables and frequently asked questions.
