The requirements, which make up the main element in Digital Construction, are defined and regulated through the Regulation on requirements for the use of Information and Communication Technology in public construction, no. 118 of 06-02-2013 and the Regulation on the application of information and communication technology (ICT) in general construction, no. 119 of 07-02-2013 and their associated guidelines. The Regulations are also known under the synonym "ICT regulations". The regulations and the associated guidelines state who is subject to the requirements.
The digital developer requirements include a number of requirements, distributed within the following areas:
- ICT coordination
- Managing digital construction items
- Digital communication and ProjectWeb
- Use of digital, object-oriented building models in connection with project competitions, project planning and execution
- Digital bids and offers, including bids with quantities
- Digital delivery upon delivery of the construction project
- Digital defect information.
Companies that want to bid on government, municipal, regional or general construction jobs over certain amount limits must meet these requirements.
Digital building models
Digital building models and visualisations in project competitions establish a better basis for decision for the developer, which helps ensure the best possible presentation of the architectural, functional and technical conditions of the proposals. With object-oriented building models, the assessment committee has an even better opportunity to form a spatial overview of the project, to assess whether the presented project overall meets the developer's requirements for area needs, volumes, height limits plans, etc., as well as to carry out independent visualisations and simulations of the project and its surroundings.
The Danish Building and Property Agency makes demands on the use of object-oriented 3-D building models in competitions, and the model must be exchanged in IFC format.
During project planning and execution, the digital building model can be used to take advantage of the possibilities for design and execution optimisation as well as quality assurance of the overall project material, which the building models provide throughout the entire project sequence. In the end, it is ensured that the digital project information, which is drawn up throughout the construction process, is structured in preparation for use as documentation for the construction project and as a direct basis for the future building management.
