Public-sector requirements for digital construction
In Denmark there have been requirements for the use of IT, BIM and common standards for public buildings, among other things with the 5-10 developer requirements in The Digital Building regulations. The new ICT regulations that came into force on 1 April 2013 will now have major consequences for a great many Danish consultants, developers and entrepreneurs.
The new regulations now impact on a larger section of the buildings as all public and publicly supported buildings with a total contract sum in excess of DKK 5 million (ex. Danish VAT) are covered, as is social housing construction and renovation with a total contract sum in excess of DKK 20 million (ex. VAT).
There are still requirements regarding project web, digital tenders, digital delivery and digital deficiency lists, but now there are also new requirements for the use of Building Information Models (BIM). Among other things, these include:
- Object-based models throughout the entire building project including competitions.
- The objects must be classified, named, encoded and identified according to the developer’s wishes.
- Relevant operational data must be applied to the objects.
- Exchange and delivery of BIM and operational data must always take place in IFC format.
Despite the fact that BIM has been a requirement in public-sector projects since 2007, there are still many consultants who have not taken embraced these systems and who still enter competitions using “old fashioned” 3D programs (such as SketchUp and Rhino) and design in 2D-CAD (e.g. AutoCAD), which means that they cannot benefit from the advantages and security that is provided by a BIM-based working method.
In the same way, there are still not that many developers and operators who base their operation and maintenance on the BIM projects that they have a right to expect from their consultants. With a BIM-based operation and maintenance system, you can import operational data through the BIM model and in this way ensure a graphical management of information, as you can see which objects in the model the information belongs to.
For the operation and maintenance system to be able to work with the consultants’ models regardless of the software that it is compiled in, it is extremely important that the system has a strong IFC translator. It is also essential that the operation and maintenance system can synchronise with the BIM model, so that the changes you make regarding operation are automatically reflected in the BIM project. This means the model is always updated and should be exportable to consultants – once again through the IFC files that can be opened in any BIM program.
There are very few BIM-based operational systems on the market that can both import and export IFC files, which is what the new ICT regulations open up for. BIM Equity sells ArchiFM, a program that does indeed work with BIM-based operation and maintenance in this way.

Operational systems are never better than the information (or models) that are loaded into the database. The new ICT regulations therefore underline that the developer ought to lay down requirements for the information required for operation and the structure in which it must be delivered. These requirements are registered in what is known as an IDM.
The operation and maintenance system does not always need to be built on the basis of new buildings where you can lay down requirements for the design consultants. The majority of new operating systems must be utilised in existing buildings, which imposes great demands for effective digitisation that complies with the same requirements as the documentation of new buildings. At BIM Equity we can deliver operating models in BIM format (such as IFC) based on existing 2D drawings (for example scanned hand drawings or 2D-CAD (DWG)) or based on registration and surveying. We use laser surveying directly to BIM via Flexijet 4 Architects, som sikrer en hurtig opmåling, der kan importeres direkte i alle BIM-kompatible systemer.

The new ICT regulations are a gift for consultants, developers and entrepreneurs if they know how to benefit from them, rather than viewing them as “even more bureaucracy of the construction industry that only adds costs and kills creativity”. BIM Equity has therefore specialised in advising developers and entrepreneurs about the new ICT regulations. In cooperation with us, you will learn how the new ICT regulations can be used to make your business more profitable.
