The Government Services Centre in Salzburg is the biggest structural engineering project in the history of HABAU to date. The traditional topping-out ceremony was held on 27 November, thus marking a further important milestone in the construction process.
With the topping-out ceremony for the new Government Services Centre in Salzburg, HABAU GROUP company HABAU Hoch- und Tiefbaugesellschaft m.b.H, along with its consortium partner Swietelsky AG, has reached a significant milestone on behalf of the state of Salzburg. Following the successful groundbreaking last year, yesterday the symbolic act was celebrated to mark the end of the shell work and thus the start of the final construction phase. The estimated completion of the large-scale project is planned for the end of 2026.
“The topping-out ceremony is a very special moment for us – it represents cohesion, precision and the utmost construction quality”, emphasises Hubert Wetschnig, CEO of HABAU GROUP. “With the Government Services Centre, we’re realising the largest structural engineering project in HABAU company history. This construction project is an impressive display of just how well the partnership-based cooperation between the client, planning, site manager, all trades involved and our consortium partner works.”
Modern administrative building with a focus on sustainability and efficiency
Commissioned by the state of Salzburg, a modern administrative building is to be built directly next to the main railway station, and in future will be home to a large, public citizen service area as well as around 1,300 employees. Covering a land area of roughly 10,000 square metres, the Government Services Centre will become a central location for the provincial administration and a new architectural accent in the urban landscape. The flagship project comprises a total of 13 floors: nine upper floors, the ground floor and three underground levels, which will be built centrally with cantilevered elements.
Construction work is striding ahead as planned: worth a particular mention here is the sustainable hybrid timber construction method from the third floor upwards, which combines the latest technology with ecological responsibility. Around 2,500 wooden beams and 540 wooden supports will be used for this – a clear commitment to resource-friendly construction. Additionally, from the third floor, the pillars and beams required were manufactured as a prefabricated framing solution, which also meant a reduction in time.
Sustainability and efficiency will also be the order of the day for the next construction phase. Among other things, the building will be fitted out with around 4,500 swivelling photovoltaic panels with a peak output of 721 kWp. Added to this comes the ultra-modern building technology based on around 700 kilometres of cables to guarantee optimum energy efficiency.
Overall, the net floor space of approximately 49,600 square metres will include a company kindergarten for around 80 children, a dedicated computer centre with waste heat utilisation, parking for almost 500 bicycles, a print shop, post office, state laboratory, staff representation, citizen service, patient representation, administration academy, yard area, conference areas along with an employee restaurant and a cafe.
Challenge successfully mastered: construction work in Salzburg lacustrine clay deposit
The subsoil presented a special engineering challenge: beneath the construction site is a mighty layer of lacustrine clay up to twelve metres deep – an especially soft, aquifer substrate that placed incredibly high demands on the planning, statics and construction. Thanks to cutting-edge construction technologies, precise pre-planning and the close cooperation of all involved, this complex task was successfully mastered. “The technical challenges were huge, but they strengthened our cohesion. Now we’re looking forward to the final construction phase”, Wetschnig concludes.
