In the context of the city, every profession has their own solutions for data management, using different sources, information structures, and systems, like 2D maps and GIS for urban planners, 3D BIM for architecture, or management systems for utilities. Most of these are fragmented, standalone GIS or BIM software platforms with limited integration possibilities. There are integration solutions between the two technologies, but most of them approach from a platform perspective. We describe a different, practice-based, and task-driven approach demonstrated through case studies. Our work started with solving different tasks in an urban district-scale development. Here, several stakeholders and projects need to be synchronized not only across building sites but also with tourism, diplomacy, and residents. We call the technical structure and workflow that handles all subsystems and data exchange City Information Management (CIM). This can bypass the differences between GIS and BIM worlds, helps operation, and can provide up-to-date information for coordination and planning as well as events. Our solutions and software choices feed from practice as we are mainly planners, not software developers. Our software environment can manage data, workflows, and registers from a single source of truth (SSOT), with a seamless interpretation in GIS and BIM, and can provide plans, schedules, and reporting. As an environment of different software and self-made solutions, the services provided by it can be adjusted and expanded on demand to fit the nature of a project.
