The aim of the DigSmart project is to establish digitization along the value chain in civil engineering, from planning to documentation, across the entire technically available breadth of organizational and technical data. Data from a variety of digital sources is to be made usable on site at the construction site. These include, for example, topographical data as well as surveying or geodata, such as those provided by geodata services and land registry offices. Also of great importance are the routes of cables and pipes, such as those available from the route information services of energy suppliers and telecommunications providers. In practice, a comparison with the actual conditions by means of an on-site survey is always indispensable. Deviations and additions must be recorded both for operational construction and for the final documentation. Finally, this information must be supplemented by data from planning and construction.
