Digital solutions have increased efficiency in different ways in the construction sector. The purpose of this project is to investigate differences after the implementation of digital tools, both for the better and the worse regarding construction errors, as well as how digital tools are used together with other tools and methods. This work also includes studying how the form of contract affects coordination. Three questions have been raised; (1) Has the implementation of digital tools limited design faults and what problems remain? (2) How do digital tools work in combination with other methods? (3) How does the form of contract affect coordination in relation to the use of digital tools?

The investigation consists of three investigated projects and 9 interviews with people who worked on the investigated projects, it shows that digital tools do not contribute to fewer errors as the planning generally requires more than is given and that less time is spent on production of drawings than before the implementation of digital tools. Communication gaps are also a significant cause of errors, problems and delays which can be between architect, designer, contractor, subcontractor and so on.

For construction projects to flow better, it is necessary that more time needs to be spent on planning in order to be able to carry out all steps more accurately in order to be able to prevent errors and problems during the construction phase which take time and contribute to increased costs. Modern design processes with digital tools are not considered to contribute to fewer errors as it often leads to careless errors when the documents can be produced so much faster and that the designers rarely get to know what the problem was, which means that the problem is repeated.
