The proportion of multi-storey, large-volume wooden buildings is tending to increase in Austria. Building technology installations in timber construction result in modified cable routing structures, adapted detailed designs and assembly processes compared to solid mineral construction. This requires an adjustment of the planning, execution and interface coordination, tailored to the degree of prefabrication of the wooden structure. In addition, the protection of the construction against moisture is of central importance, especially in timber construction. At the moment, however, there is no training offer that deals in detail with the requirements for TGA installations in timber construction or specifically with prefabrication, which leads to uncertainties in the execution. TGA planners and installation companies are therefore faced with the challenge of how to pass on knowledge to their employees for these new tasks in timber construction. In order to close this gap, TU Graz initiated the qualification seminar TGA <- -> Holzbau together with Holzforschung Austria in 2019.
The qualification goals of the seminar consist of the training of the participants in order to meet the high requirements of installations in timber construction in terms of moisture protection, building physics requirements, assembly speeds and consideration of the degree of prefabrication. Another training goal was the optimization of the work processes by using lean construction in order to be able to coordinate the assembly sequence of the TGA installation work - even with conventional construction site production - to the accelerated assembly of the timber construction. The aim was to increase both the quality and the economic efficiency of the TGA installation work by standardizing the processes. The field of participants, which consisted mainly of TGA planners and contractors, was expanded to include a timber construction planner and a timber construction contractor in order to gain positive feedback effects by including the aspects of various specialist planners and trades through critical discussion.
The content of the qualification was divided into the five modules of planning, building physics requirements, detailed training, lean construction and cost-effectiveness, with the detailed content being specifically adapted to the needs of the participants. The qualification content was conveyed by means of lectures and, based on this, workshops with application examples were carried out to deepen the knowledge and adapt it to one's own construction tasks. Through this method, the companies learned to apply the level of knowledge specifically for their own projects and also to pass it on to external project partners by means of a snowball effect. Furthermore, the innovation potential of the participants was increased by communicating the possibility of optimizing the construction process using lean construction, which enables competitive solutions and a more economical implementation of client tasks in the area of building technology installation in timber construction.
The project TGA <- -> timber construction enabled participating companies to consider the topic of building technology installation in timber construction in an interdisciplinary and holistic way and links the two disciplines of planning and execution through the composition of the participating companies. They got to know and apply current developments from research as well as existing, less common principles, which, combined with the topic of lean construction and economic efficiency, led to a higher qualification of the participants. In addition, the qualification seminar intensified the transfer of knowledge between universities and companies and the associated anchoring of company-relevant teaching and research priorities at Graz University of Technology.
