The differences between AB 25 and AB 04 – what does the new consultation draft mean for the construction industry?

What is new in the consultation draft of AB 25? We have analysed the latest version of the General Conditions (Allmänna bestämmelser).

The construction and civil engineering industry is constantly changing, and we are now facing one of the most significant updates in many years – the introduction of AB 25. This new version of the General Conditions of Contract for Building, Civil Engineering and Installation Works brings several changes that will affect both clients and contractors. So what is actually the difference between AB 25 and its predecessor, AB 04? Here is a summary of some important points.

One of the biggest changes in AB 25 is the clear focus on digitalisation. AB 25 introduces provisions on the use of digital models and rules for how these are to be handled throughout the contract process. It is not only about providing digital documents, but also about how they are to be accessible, traceable and usable by all parties. This is a big step forward from AB 04, which lacked this kind of specific rules for digital information flow.

AB 25 emphasises the importance of cooperation and loyalty between the parties. There is a strong focus on communication and transparency, and higher demands are placed on both sides to work together to ensure a successful project. This is clearer and more structured regulation than in AB 04, and it reflects today's demands on complex projects where several parties are often involved.

AB 25 has more detailed provisions on inspection and control than AB 04. The client gets greater opportunities to check the work on an ongoing basis, and the contractor has a clearer obligation to remedy any defects. In addition, the client's right to stop work in particular situations is now regulated, which creates a more transparent process for both parties.

Another important change in AB 25 is the sharper division of responsibilities, particularly regarding the work environment, risk management and design. The contractor has been given greater responsibility for ensuring that the work is carried out in accordance with applicable legislation, while the client is responsible for ensuring that the necessary permits and inspections are carried out.
