Founded in 1996 RWT Plus is specialized on structural design of lightweight structures. With locations in Vienna and Feldkirchen, and our competent team, we service the entire Central European region. We also provide national and international projects, including Germany, Hungary, Czech Republic, Poland, Russia and Abu Dhabi.
An important objective of our office is the general consultation, with the exception of architecture. This allows developers to choose freely the architect, while ensuring trough our experts the best possible implementation of the architectural idea. Our goal is the close interdisciplinary collaboration with the architects.
With the pillars structural engineering, building physics, construction controlling and management, we offer a comprehensive construction management and are able to ensure customers a propper execution of its construction project. Comprehensive knowledge and experience gained from many successfuly completed projects are the basis for developing innovative ideas and implementation. Our particular strengths include know-how transfer and resource management.
Since the foudation of research and innovation devision in 2005, we can now consider ourselves an inovativ and creativ engeneering office. Due to the cooperation with the technical universities and other research institutes, we are making active use of research for innovative products as well as acquire additional competence in the visionary field and therefore gaining a competitive advantage.
The findings and the acquired knowledgewill be implemented in structural design of wood construction, as well as steel and glass construction.

We create together with architects out of various materials such as reinforced concrete, steel or wood structures that meets both technical and design specifications. Here a functioning interaction between architects and engineers is essential.
Neither should the construction be determined by architecture, nor vice versa. Ideal for all involved partys, therefore, is to identify and explore the possibilities of the support structure already in the planning phase and include them effectively. From the first moment of the brainstorming and idea finding, we work, and think toghether with the architects to come up with the best technical implementation, and thanks to our know-how team we implement the formal language of the architects appropriately.
In this way we develope innovative structural concepts and solutions that meet both requirements of the client as well as the architects.
Based on our long-term experience in building physics and a wide range of knowledge in economic efficiency around construction projects our goal is to optimize the energy consumption respectively decrease the needs without compromising the life quality. Especially in view of rising energy prices it is economically recomanded and will gain importance in the future.
Besides the purely economic aspects we also keep a close eye on environmental impact. The sustainability of the measures implemented are a key element/ central objective for us.
Our solution capability in the area of physics includes not only thermal issues, but also the sound insulation and fire protection. In tangible terms, we also create the building pass, which contains a wider range of information than the conventional energy certificates.
We offer since 1999 services of building support in accordance to the Act on the Coordination of Construction Works (BauKG), as well as the overall package of the local construction supervision and construction managemnet. Our companies are involved in executive functions on a project or building. We take over the site supervision and coordination on the construction site in order to ensure the proper execution of the work and as well the fulfillment of conditions.
The Woschitz Group in Burgenland has a leading role. Following the dialogue with the labor Inspectorate initial findings from the construction work coordination have already been included in the legal texts.
Client / Developer Consulting
We provide comprehensive construction management consulting services for the developer/owner in his duties and responsibilities as a builder through our knowledge, our experience and expertise in the field of the construction and real estate industry. Thus we enable the public and private owners even those who operate outside the sectore, to make competent and sustainable choices during the development, the construction and use of a building.
Our goal is to realize the proposed project in accordance with the wishes and requirements in a apropriate quality, efficiently and commercially feasible using the vast and longtime experience for public institutions as well as for private builders.
From the concept through development, implementation and use to disposal or Recycling – providing all of these services in all stages from a single source and rely on its own know-how – the associate offices of Woschitz-Group and a team of qualified and experienced specialists in the field of construction and real estate industry realise your projects
Research & Innovation
Through exceptional pilot projects, we make an active and valuable contribution to innovation. So we have developed for the B61a Pullendorfer Straße a single span integral bridge, which will be implemented as a bridge family of three similar systems.
The main point of modeling was the ilustration of a strong haunched bridge abutment. Besides classical calculation using beams and shell elements finite volume elements (tetrahedral) were also used for comparative calculations.
The Franz Liszt Concert Hall is regarding to the inovative facade system of a pilot project. Herby we used all the manufacturing acumulated experience in order to transform an individual approval into an inspected and a high-quality system with all of the required inspections and cetificates.
Through the „eNNOVATION“ project should be achieved a functioning know-how and technology transfer between science and industry. The knowledge gained from external sources should in the future be even faster usable, research and development results utilized more quickly. This involves not just a tranfer of knowledge, but the creations through know-how consolidation and synthesis added value and new knowledge.
