Vienna introduces mandatory BIM building modeling
The Vienna City Council has begun to utilize the modern method of 3D building modeling BIM, which increases the efficiency, sustainability, and transparency of construction projects. The pilot project was launched last summer during the planning of a municipal apartment building with nearly 90 apartments. Starting this year, BIM will become the standard for all renovations of municipal apartments and gradually for entire residential blocks.
Vienna is joining cities that are utilizing advanced digital technologies to optimize the construction and management process of buildings. The pilot project was initiated by the Vienna City Hall last summer. In the 22nd district, they began to use the modern method of 3D building modeling BIM (Building Information Modeling) during the planning of a municipal apartment building on Bernoullistrasse, which is set to offer nearly 90 municipal apartments.
At the beginning of 2025, the Vienna municipal housing agency Wiener Wohnen will launch a new phase – BIM technology will become the standard for all renovations of municipal apartments, of which the council carries out approximately 9,000 per year. From next year, the agency will apply 3D modeling even to all new renovation projects of entire residential blocks. Wiener Wohnen can rely on the city's digitization project called BRISE (Building Regulations Information for Submission Envolvement), which aims to create a fully automated digital approval process.
What exactly is BIM? It is a digital technology that enables the creation of three-dimensional models of buildings. The goal is higher transparency, efficiency, and sustainability. BIM connects all participants in the construction process, from architects and designers to contractors, on one platform. This allows for the identification and elimination of potential problems already in the early phases of planning, thereby reducing costs and preventing errors.
"Thanks to BIM, we can identify, for example, clashes between individual construction components at an early stage of planning, which in the past might not have been revealed until later on the construction site, develop solutions, and thus save costs," says BIM project manager at Wiener Wohnen, Georg Knirsch.
One of the key advantages of BIM is a detailed overview of material usage. Data from the building information model offers new opportunities for sustainably reusing materials in accordance with the circular economy in the future. Digital modeling also facilitates ongoing quality control and streamlines cooperation among all parties involved. "We always know exactly what materials are used and in what quantities, which allows us to quickly and reliably assess the impact of any changes in the projects," explains Knirsch.
