Technical School Rotholz

Research and teaching under one roof

With a history of more than 70 years, the Federal Institute for Higher Education and Research in Agriculture and Nutrition as well as Food and Biotechnology is a constant in the educational landscape of Tyrol.

The three sections of the new building, designed by the architects of ARGE Adamer ° Ramsauer and BME, provide modern teaching, practice and laboratory facilities for over 1,000 students and trainees, 250 teachers and employees. 

The affiliated boarding school has a place for 200 students.  

The school building has a gross floor area of 10,373 m² with an enveloping surface of 10,984 m², the boarding school has a gross floor area of 5,682 m² and an enveloping surface of 4,144 m².

The three-storey school building for 13 classes, work and practice rooms and the teaching kitchen forms the centrepiece. This is connected to the boarding school via the double gymnasium. The ensemble, built in timber construction according to the "klimaaktiv Gold" standard, is framed by generous sports and exercise areas. 

A footbridge connects the building for research and service, where work is being carried out to strengthen agriculture and dairy farming in the Alpine region and where the school sees itself as a point of contact for all questions concerning milk processing, from the raw material milk to the finished product.

just in time

ingenious assembly process protects visible surfaces

The Rubner Holzbau team at our Villach branch was responsible for the factory and assembly planning of this new school building. The main assemblies can be divided into the glulam structure for the school (a timber-frame construction), the timber-concrete composite ceilings for the floor slabs and the roof, facade elements in post-and-beam construction and the prefabricated larch façade-elements for the school and boarding school buildings and the cross laminated timber walls and board stacked ceilings in the boarding school. 

The production in the Ober-Grafendorf plant was optimally adapted to the assembly conditions, so that the tight time schedule with largely prefabricated elements delivered to the construction site just in time could be ideally used. 

The sophisticated assembly concept also mastered the biggest challenge, which was to protect the large-area wood-concrete composite ceilings in visible quality for a period of 10 weeks until the roof was sealed. Floor by floor staggered sections were installed in such a way that the part below was well protected and wind and weather had no surface to attack.
