What influence does the introduction of BIM have on collaboration with external partners?
The way of working through the use of BIM requires a very high understanding of processes and competence in collaboration and communication. If you look back to the first days of our office, we were still drawing by hand. Little thought was given to interfaces in cooperation with other offices. As one of the first offices, we then introduced CAD and started to digitization. The effort at the time was big, but the introduction of BIM brought many more challenges due to the great interconnection of information.
It was precisely this interconnection that also brought about the biggest changes. For those involved, BIM makes it clear how dramatically supposedly small changes can affect other planners. This improves mutual understanding and can also simplify the planning process. One of our first hospital projects with BIM was very successful in this regard, with the result that there were no significant complications during execution and we even came in under budget.
How do you feel the topic of BIM is being implemented in the construction industry and what developments do you expect in this area?
We are in a situation where there are already some very capable offices that have been working with BIM for many years and are actively living and shaping it. As both large and government clients continue to push project delivery requirements in this direction, we expect to see further momentum as well.
What are the biggest benefits that come from BIM-compliant planning?
The achievable mass accuracy and the associated high cost security for the client certainly play a significant role. Some areas, especially in technical building equipment, with a high installation density can be planned much more precisely and thus collisions that might otherwise have to be solved on the construction site can be detected at an early stage. The company carrying out the work thus also has high-quality planning documents as a basis, which makes it easier for them to familiarize themselves with a project. Extensive simulations are also possible directly in the model.
You have been working with LINEAR’s solutions for several years. What prompted you to invest in the software at the time?
We have been using the LINEAR software since 2017. The decisive factor was the possibility to natively import models from Revit without having to handle transfer formats. The more that can be incorporated directly into our program, the easier it will be for us to use. This way we can automate processes with our own scripts and still synchronize the data in both directions with LINEAR. In the complex BIM environment, there are always new challenges to overcome.
You have already carried out numerous projects with the LINEAR solutions. What is your experience with the software so far?
We use LINEAR in combination with both AutoCAD and Revit. The software helps us to perform calculations and draw models for heating, cooling, sanitary and sewage. The possibilities brought by the scheme generator increase our efficiency. For example, the function of mass determination for panel heating improves our accuracy.
Which of the projects you have implemented make you particularly proud?
Currently, the Oberwart hospital in Burgenland, which is currently under construction. At a total cost of around 214 million, it is the largest construction project in the short history of the state, with manufacturing costs for building services amounting to around 28 million euros. The new range of services will include a cardiac catheterization laboratory, state-of-the-art equipment in radiology and dialysis, and seven operating rooms. With its approximately 320 beds, the Oberwart hospital is to become the leading hospital for southern Burgenland and the eastern region of Austria. We are particularly proud of this project in that we exceeded the client's requirements by elevating the project to a BIM project on our own accord.
