Kindergarten in Schwoich, Austria
A kindergarten, designed according to Building Information Modeling (BIM), is currently under construction in the Tyrolean municipality of Schwoich. The digital 3D model accompanies the construction project from design until completion.The architectural planning has been performed with Autodesk Revit. The structural model, including cross-sections, materials, loads, etc., has been exported to RFEM with the direct interface and designed there.
BIM Planning from Beginning to End
AGA-Bau-Planungs GmbH from Kufstein in Tyrol was mandated to perform the complete design of the project. This planning has been always carried out on the digital model. It starts with the architecture (conceptual design, approval planning and final planning) and ends with the carpentry (CNC data for joining).
For more than ten years, the engineers of AGA-Bau exclusively rely on BIM. Like for the kindergarten project in Schwoich, the structural analysis as well as the building and electrical technology, besides the architecture, are usually also designed on the 3D model. Since AGA-Bau has already realized several international projects in this way, it got involved in this EUR 3.5 million project by the municipality.
The walls and slabs of the first floor are built using reinforced concrete. On this stand a post and beam structure made of timber. The three three-story central buildings with their monopitch roofs are like canines pointing upwards. They are connected by access balconies which are glazed in the lower floors.
The timber structure is stiffened by timber framed walls with OSB plates in longitudinal and transversal direction. The kindergarten has a floor space of 1,400 m² in total.
The advantage of digital planning according to BIM is not only the time saving and cost certainty, but also that all parties could be involved in the planning process from the beginning, including the client and the childcare professionals.
"Generally, it needs to be mentioned that the planning according to the BIM method also pays off for smaller projects or smaller engineering offices.", says master builder Anton Gasteiger from AGA-Bau.

The material model Orthotropic Masonry 2D is an elastoplastic model that additionally allows softening of the material, which can be different in the local x- and y-direction of a surface. The material model is suitable for (unreinforced) masonry walls with in-plane loads.
- I have created new elements in my model. However, these are not designed. What can I do?
- How to calculate the static depth d when designing the bending of block foundations (calculation as an equivalent beam)?
- I have defined temperature loads, strain loads, or a precamber. As soon as I modify stiffnesses, the deformations are no longer plausible.
- Can the properties, such as B. the cross -section or the surface thickness as well as the material of a surface of an existing element for a new element?
- When should the punching load be determined with the (un)smoothed distribution of the shear forces at the critical perimeter?
- I would like to perform the punching shear design on a column with connected downstand beams as a wall corner or Perform wall end. However, the module applies an internal column. Is it possible to adjust it?
- I am getting the message that my material does not meet the requirements of the current standard. How can I correct this?
- Is it possible to design bidirectional ribbed plates, unidirectional ribbed plates, or hollow core slabs in RFEM?
- In RF-/TIMBER AWC and RF-/TIMBER CSA, I receive the error that says torsion limit exceeded. How do I bypass this error message?
- Why are the values of a column base, head or center on the individual columns only displayed partially for the results from the calculation in RF‑CONCRETE Columns?
