  • Adding storeys and extensions made easy

    Adding storeys and extensions made easy

    The further development of existing buildings offers clear advantages. It saves resources, reduces CO2 emissions and reduces the volume of construction waste. In contrast to demolition, the appearance of the neighborhood is preserved and new rentals are often lower, which ensures affordable living space. The local building culture also benefits, as established structures and identity-forming elements are preserved, which strengthens the sense of community.

    High hurdles hamper conversions
    Outdated regulations, complex procedures and a lack of legal certainty are currently hampering numerous extension projects. Older buildings in particular do not comply with the latest regulations, so many owners shy away from the effort involved and prefer to build new ones.

    Revision of the law brings simplifications
    The new proposal from the Building Department provides for targeted simplifications. At its heart is the simplification provision, Section 220a E-PBG: it allows owners to deviate from certain regulations, for example with regard to boundary distances, façade height and the number of full storeys. The aim is to better integrate the further developed building into the existing building regulations, create more scope for conversion and at the same time offer legal certainty.

    Densification and better utilization
    It will be easier to create additional residential units, particularly in residential buildings. The regulation encourages properties to exploit their full potential in accordance with the municipal zoning regulations without losing the existing building stock. This is an important step towards more densification and smart land use in urban and rural areas.

    Further simplifications and updates
    The revision also addresses the demands of the Cantonal Council. For example, procedures for solar installations and stair lifts have been simplified. Outdated regulations on fire protection and minimum heights are to be removed. This will make it easier to convert office buildings into apartments and provide impetus for innovative construction projects.

    Opportunity for Zurich
    The planned simplifications for the conversion and extension of existing buildings will enable sustainable urban development, ecologically, socially and culturally. The revision of the law creates clarity and motivates owners to use the potential of existing buildings instead of building new ones.

  • PFAS in construction waste

    PFAS in construction waste

    Around 7.4 million tons of mineral construction waste are produced in Switzerland every year, with demolition, refurbishment and new construction continuing to increase the quantities. It is not only asbestos and PCBs that are problematic, but also PFAS (per- and polyfluorinated alkyl substances). These chemicals are considered carcinogenic and accumulate in the human body.

    A study by the University of Bern found up to seven PFAS substances in 20 samples of demolition material, some in concentrations of up to 5 micrograms per kilogram. Although the quantities are considered low, the research team recommends further investigations. Landfills are usually not sealed, PFAS can be washed out and thus enter the groundwater, where they pollute the food chain and drinking water.

    Measurements and new standards
    The Swiss Building Materials Association Circular Switzerland and the Federal Office for the Environment are working together with cantons and independent laboratories to determine PFAS contamination in gravel works, concrete plants and existing buildings. The investigation is nearing completion. The findings are to be incorporated into a practical guide for dealing with PFAS. The federal government is planning limit values for PFAS in contaminated sites and waste by 2026, which construction companies will have to comply with in future.

    In civil engineering, the Federal Roads Office has recommended avoiding PFAS-containing substances for the time being. Due to the lack of legislation, Astra is not yet able to enforce any bans, but is working on checklists for PFAS-free construction products.

    Health risk and circular economy
    The Federal Office of Public Health is monitoring the PFAS problem in indoor spaces and warns of its persistence. PFAS bind to materials for a long time and become problematic when abraded and inhaled, but have so far been less relevant in the living environment, as the main source remains food. According to the authorities, the risk of exposure from building rubble and landfill sites is greater. This is because rainwater washes PFAS into the groundwater and thus into the food chain. Although leachate is technically purified, the risk of uncontrolled contamination remains.

    The Building Materials Association emphasizes that the recyclability of demolition material is endangered by the new limit values. At the same time, the industry wants to keep the chemicals out of the cycle. Professional removal and disposal are possible, but it is calling for clear and practicable guidelines from the federal government.

    PFAS in Swiss soil
    A recent Swiss study shows that PFAS can now be detected in all topsoils, even in remote forest and mountain areas. Point sources such as fire extinguishing training grounds and electroplating plants increase local pollution. Agricultural soils in particular contain high PFAS levels, often caused by sewage sludge used as fertilizer. The large number of applications makes it difficult to trace the origin.

    Political debate on PFAS
    Following the detection of PFAS in meat from the canton of St. Gallen and the first bans, parliament has also taken up the issue. The authorities and the industry are working together on a mix of measures to protect the population and the environment. Environment Minister Albert Rösti confirms the seriousness of the situation. The government wants to respond with limit values, guidelines and tighter controls.

  • Farewell to imputed rental value

    Farewell to imputed rental value

    The adoption of the bill on the cantonal property tax for second homes marks the end of the imputed rental value. However, the change will take effect in two to three years at the earliest and will fundamentally change the everyday lives of many of those affected. Not only owners of owner-occupied and rented properties will feel the effects, but also households with debts without property ownership.

    Simplifications and exemptions
    With the abolition of the imputed rental value, maintenance costs and debt interest will also no longer be tax-deductible. However, to make it easier to purchase residential property, special rules apply for the first ten years after purchase. Debt interest of up to CHF 10,000 for married couples and CHF 5,000 for single persons is still deductible, but the remaining maximum amount is reduced by ten percent per year.

    Tax declarations will be simpler and the tax burden for many homeowners will fall in the current interest rate environment. Value-preserving and value-enhancing costs should be properly documented, as in future they can only be claimed when property gains tax is paid, i.e. when the property is sold.

    More restrictions on the deduction of debt interest
    Owners of investment properties are particularly affected by the reform. Interest on debt can now only be deducted in proportion to the value of the property in relation to total assets. This increases the tax burden and significantly limits the previous advantages.

    Taxpayers without real estate
    Households without real estate are also affected. Private debt interest, for example for loans or small loans, may no longer be offset against tax in future. This turns previous practice on its head and may lead to higher tax payments.

    Uncertainties and cantonal competence
    The cantons will have the option of levying a special property tax on second homes. This is a particularly sensitive issue for regions with a high level of tourism, as new taxes can affect the attractiveness of the market. It remains to be seen what the specific assessment bases will look like and which cantons will make use of the new options.

    The cantons can continue to allow temporary deductions for energy-efficient renovations and environmental protection measures until 2050. It is not yet known which cantons will offer this.

    Strategies for mortgages and investments
    The reform not only affects the tax rate, but also personal financial strategies. The question of how high mortgages should be set in future and whether amortization makes sense is becoming increasingly important. Anyone who uses capital for amortization ties it up in the property and loses liquidity for other purposes such as retirement provision or new investments. The decision on the optimal financing therefore requires individual consideration.

    Effects on the real estate market
    Whether the reform affects prices depends above all on the situation of new buyers, the majority of whom are highly mortgaged. According to SNB statistics, 40 percent of newly purchased homes are financed at over 74 percent of their value. Older properties in particular continue to lose tax advantages due to the limited deduction options. New condominiums in the canton of Zurich are on average 20 years old, single-family homes even around 50 years old. The fundamental challenges of high prices and scarce funds for acquisition remain unresolved by the reform.

    The abolition of the imputed rental value promotes the price difference between new buildings and older properties. Second homes are likely to become less attractive as a result of the new property tax, but experts do not expect prices for vacation homes to fall, as the supply shortage is too great.

    Prices for Swiss homes could rise by 4% this year and 4% next year, and by as much as 4.5% in the canton of Zurich. Renovating and maintaining the value of old buildings is becoming more important than ever, but not every investment pays off. Homeowners need to keep a keen eye on their long-term strategy: Is refurbishment worthwhile or is a new replacement building imminent?

    Reform as a joint project
    The changes are based on a close link between legislative and constitutional amendments. The abolition of the imputed rental value will only come into force if the referendum on the new property tax on second homes is successful. Parliament discussed the scope and form of the tax intensively for months. In tourist cantons in particular, there is a great deal of skepticism as to whether reduced revenue can be offset by new taxes. The laws come into force together, a reform with many facets.

    Tax and financial effects at a glance
    The mortgage interest rate determines whether owners benefit. If interest rates are low, the tax burden falls for the majority. If interest rates are high, taxes increase because interest on debt can hardly be deducted any more. For the public sector, the reform could result in a loss of revenue of CHF 1.8 billion. From 3 percent mortgage interest, however, additional revenue is possible for the state as a whole. The actual effects remain unclear for the time being due to various uncertainties.

  • Wood takes centre stage: 1500 guests at event in Worb

    Wood takes centre stage: 1500 guests at event in Worb

    OLWO, which claims to be the central production and trading service provider in the Swiss timber industry, welcomed around 1,500 guests to its sawmill in Worb on 12 and 13 September 2025. The company transformed the area with marquee and wrestling ground into a meeting place for families, experts and people interested in wood, according to a press release. Young wrestlers among those interested in wood were also delighted to receive a surprise visit from former wrestling king Christian Stucki.

    The Days of Swiss Wood 2025, during which the event took place, were organised by the umbrella organisation Lignum Holzwirtschaft Schweiz and its affiliated companies from the forestry and wood industry. The aim of the events was to promote Swiss wood and a sustainable construction industry that focusses on regional resources and sustainable value creation.

    OLWO, a fourth-generation family business, has a proprietary sawmill and planing mill and a comprehensive range of wood-based materials for craftsmen, architects and builders. At the company headquarters in Worb, customers are offered solution-orientated sales advice from around 30 wood specialists in addition to regional woods and materials.

  • Mobile research factory optimises concrete construction for Hyperloop test facility

    Mobile research factory optimises concrete construction for Hyperloop test facility

    The EuroTube Foundation celebrated the opening of its innovative research facility for sustainable infrastructure on the grounds of the Innovation Park Zurich(IPZ) on 16 September, the foundation announced in a press release. The Smart Mobile Factory produces concrete components for the DemoTube hyperloop test facility being built at the IPZ. The innovative factory was developed by the EuroTube Foundation in collaboration with the Swiss Federal Institute of Technology in Zurich, Delft University of Technology, Eindhoven University of Technology and the Free University of Bozen-Bolzano.

    The new factory deserves to be called intelligent, as its construction control is linked to a digital twin via sensor data, writes EuroTube. In this way, material flows, processes and CO2 emissions can be continuously optimised during construction. The factory, which is set up in a few standard containers, can also be moved and flexibly set up along infrastructure projects.

    At the IPZ, the Smart Mobile Factory will not only produce components for DemoTube, but will also be available to other researchers and start-ups who want to develop and test their own technologies directly on an active construction site. To this end, the EuroTube Foundation has launched the Real Laboratory for Infrastructure Construction educational programme. “As a research partner of the Innovation Park Zurich, we are proud to support projects, start-ups and companies in the development of new products for the transition to sustainable mobility infrastructures,” said Antoine Juge, Managing Director of the EuroTube Foundation, in the press release.

  • Digital solution makes progress on greenhouse gases visible

    Digital solution makes progress on greenhouse gases visible

    The Zurich-based company Integrale Planung GmbH(Intep) has launched a new emissions tracker designed to make it much easier for SMEs to get started with carbon footprinting, according to a press release. The web-based tool also visualises the results and enables a multi-year comparison. The aim is to make progress clearly visible and measurable.

    The Emission Tracker is based on the Greenhouse Gas Protocol and covers all three scopes, including indirect emissions along the value chain. The emission factors have been scientifically validated and are updated regularly. Activity and emissions data that Intep was able to collect during its project work also enables a simplified calculation methodology using industry averages.

    The visualised results provide an overview of the main sources of emissions, from energy supply to expenditure and investment. A PDF report can be used for communication and also offers practical tips for reducing emissions. With the Emission Tracker Plus, companies can also receive an additional two hours of personalised advice from Intep experts.

    “SMEs in particular often lack the financial resources, the right tools and the necessary expertise,” explains Dr Lisa Winter, Managing Director at Intep Berlin. “With the Emission Tracker, we provide them with a low-threshold introduction to greenhouse gas balancing.” Associations, municipalities and large companies can also benefit by acquiring licences for their SME network as part of the Emission Tracker partnership.

  • Autonomous shuttle buses reach new test phase at the airport

    Autonomous shuttle buses reach new test phase at the airport

    The pilot project for autonomous shuttle buses at Zurich Airport has entered a new phase. According to a press release, the project has reached automation level 3. This means that airport employees can use the buses for their commute between the airport head (Gate 101) and the maintenance depot (Gate 130). There are security drivers on board the buses who can intervene in the event of a problem. So far, the buses have travelled without passengers in an initial test phase.

    The current success is due to the co-operation between several airport departments and the technology partner WeRide. Preparations included setting up a new IT infrastructure, hundreds of test drives and a large number of technical checks. In addition to training, regulatory requirements and technical processes were also optimised.

    In a further phase, journeys are carried out without a safety driver using a remote cockpit. If these journeys without passengers are successful, the buses could then also drive autonomously without a driver. “We assume that we will be able to carry out the first tests with remote monitoring and without a safety driver by the end of the year at the earliest,” says Raphaël Glaesener, Senior Innovation Manager at Flughafen Zürich AG, in the press release. If successful, Zurich Airport would be the first in Europe with autonomous driving on its premises.

  • Lighter and stronger: new generation of network arch bridges

    Lighter and stronger: new generation of network arch bridges

    A new border bridge has been spanning the Oder near Küstrin since last year. It is held in place by a network arch with a span of 130 metres and 88 carbon girders. According to a recently published Empa press release, these carbon tensioning cables were developed by Carbo-Link, an Empa spin-off from Fehraltorf. The carbon carriers are made of carbon fibre reinforced plastic (CFRP).

    This innovative material not only enables flexible processing, but also saves a large amount of carbon dioxide that would be released by conventional steel constructions. The use of carbon fibre beams significantly reduces the dead weight compared to conventional flat steel hangers. Around 500 tonnes of steel and 1350 tonnes of reinforced concrete were saved in the construction.

    A major advantage of the new suspension cables is their high tensile strength and lower fatigue than steel. Most of the fatigue tests were carried out by a team from Empa’s Structural Engineering department and confirmed the necessary fatigue strength of the new CFRP material. “We have thus created the basis for a new generation of filigree network arch bridges with carbon hangers as load-bearing elements,” Giovanni Terrasi, Head of Empa’s Mechanical Systems Engineering department, is quoted as saying in the press release.

    Visually, the new materials offer design freedom, as the Oder bridge shows. Carbon girders have already been used in other bridge constructions, but the special feature of the Oder bridge is that it is being used for the first time for heavy goods railway transport. Trains can pass over it at a speed of 120 kilometres per hour. The bridge has been honoured with both the German Bridge Construction Award and the British Bridges International Award.

  • Dwindling interest in electric cars in Switzerland

    Dwindling interest in electric cars in Switzerland

    Based on the results of the third AXA Mobility Survey,AXA Switzerland warns that dwindling interest in electric cars could jeopardise the mobility turnaround. According to a statement from the insurance company headquartered in Winterthur, the figures generally give reason to speak of a trend reversal for the automotive market: Between 2023 and 2025, the proportion of those planning to buy a car rose by 12 per cent to 34 per cent. At the same time, only 24 per cent are considering an electric car; in 2023, this was an option for 34 per cent. The underlying representative survey was conducted in May 2025 in cooperation with the Sotomo research institute in Zurich.

    According to the study, electric mobility is currently rejected by 30 per cent of respondents, compared to 25 per cent in 2023. The growing reservations relate to range, price and charging options. According to the press release, the used car market for e-cars continues to lag behind that for combustion engines. The reasons for this are concerns about the condition of the battery and the rapid pace of technological development. At the same time, the reputation of electric cars has fallen by 9 per cent in the past year. “Despite these obvious difficulties in getting electric cars accepted, only a minority of 38 per cent are still in favour of greater political support for the drive technology,” Sotomo Director Michael Hermann is quoted as saying.

    Regardless of the drive technology, AXA is observing that German makes are the undisputed leaders in the wake of the upturn in the automotive market; Chinese makes, particularly BYD, are catching up. Electric cars from the USA are losing popularity.

    The survey also asked what the population thinks of autonomous driving: Scepticism prevails here, mainly due to safety concerns and possible cyber attacks. The majority of car owners are concerned about the misuse of their vehicle data, according to the survey.

  • First fast-charging station for electric cars opened in Adelboden

    First fast-charging station for electric cars opened in Adelboden

    Adelboden now has its first direct current fast-charging station for electric cars. According to a press release, the station at Licht- und Wasserwerk Adelboden AG(LWA) at Dorfstrasse 36 has a capacity of 50 to 100 kilowatts. This means that electric cars can be charged within 30 to 60 minutes. LWA now offers a total of 20 public charging points at six locations in Adelboden.

    LWA sees the fast charging station as a milestone for sustainable mobility in Adelboden. “Every charging break is an invitation to explore Adelboden’s village centre,” says Pascal von Allmen, Managing Director of LWA, in the press release. This benefits not only car drivers, but also local businesses.

  • Investment in modern workplaces and training

    Investment in modern workplaces and training

    The Ferrum Group has inaugurated its new ferruBase extension at its Schafisheim site, according to a press release. With the new building, the mechanical engineering company has realised a vertical production structure that creates space for 240 new office workstations, fully equipped production rooms and a future-oriented training workshop on around 14,000 square metres of floor space. More than 1,000 guests attended the opening and were able to gain an insight into the new building during expert tours.

    According to the press release, the new building seamlessly combines modern production processes with ergonomic office design and a training workshop. During the guided tours, employees, family members and guests were able to gain an initial insight into the architecture, construction method and new machinery. Catering was also provided at the opening ceremony and a varied entertainment programme was offered.

    For Ferrum, the new building is an investment in the future viability of the company and is intended to secure jobs in Aargau in the long term. At the same time, it also demonstrates how tradition and modern technology can be successfully combined.

  • Architecture prize honours outstanding building projects in the canton of Zurich

    Architecture prize honours outstanding building projects in the canton of Zurich

    The Foundation for the Honouring of Good Buildings in the Canton of Zurich has awarded the Canton of Zurich Architecture Prize, which is presented every three years, for the eighth time. The jury honoured four projects in each of the categories of distinction and recognition for their design quality and innovative approach to current challenges, as detailed in a press release. The foundation is supported by the Canton of Zurich’s Building Department, the Zurich section of the Association of Swiss Architects, the Swiss Werkbund and Zürcher Kantonalbank.

    The Leutschenbach high-rise ensemble in Zurich and the complete refurbishment of the Im Birkenhof housing estate were recognised in the award category, as were the temporary sports buildings in the canton of Zurich and the Wallrüti school building in Winterthur.

    The ensemble of three residential buildings in Kleinandelfingen, the new extension to the Limmattal cantonal school in Urdorf, the communal living project in Roter Kamm in Zurich and the Hobelwerk, House D in Winterthur were recognised. The Swiss Life Arena in Zurich received the Audience Award. This was awarded in an online vote that ran from mid-April to the end of May.

    The foundation also honoured the Hobelwerk, Haus D in Winterthur with the sustainability award Der Grüne Leu. This honours architects who have dedicated themselves to ecological sustainability and developed their own aesthetic and architectural language.

    “Good architecture ensures well-being, efficiency and value retention. It takes sustainability into account in many dimensions. For example, in achieving the social objective of inward densification of our residential areas while at the same time creating valuable recreational spaces,” Heinz Stecher, Key Account Manager Construction/Real Estate at Zürcher Kantonalbank and member of the Foundation Board, is quoted as saying in the press release.

  • Six Innovation Awards for construction and tool solutions

    Six Innovation Awards for construction and tool solutions

    Hilti has received six awards for recently launched products at the Pro Tool Innovation Awards(PTIA) 2025 in the USA, according to a press release. The internationally active manufacturer and supplier in the construction and tool sector is headquartered in Schaan, Liechtenstein, and is active in over 120 countries. Hilti took part in the annual PTIA competition through its North American headquarters in Plano, Texas. In total, more than 400 product solutions from over one hundred manufacturers were submitted, according to the report. A jury of experts assessed the degree of innovation, performance and safety and ergonomic aspects, among other things. “We are delighted with the high level of innovation this year,” said Clint DeBoer, General Manager of the PTIA, in the press release.

    Hilti was honoured for products in various categories. The new DD 150-U-22 diamond core drill came out on top in the concrete and masonry core drill category. It works cordlessly and is equipped with an oscillating function that makes it easy to remove a core from the drill bit. The VC 5 construction hoover, the PR 400-22 rotating laser, the DSH 700-X petrol grinder, the new KCCM Kwik Cast Connect anchor system and a filter system for vacuum cleaners (VC-CB 20/40/150-X) also came out on top in other categories.

    At the Swiss innovation conference Open-i in November, the CEO of the Hilti Group, Jahangir Doongaji, talks about how research and development (R&D) is prioritised and embedded in his company. “At Hilti, we drive innovation in a targeted manner so that our customers can build more productively, safely and sustainably,” said Doongaji in the run-up to the conference. In Hilti’s R&D and test centres, experts are working on solutions for selected areas such as occupational safety, productivity and technology integration.

    Open-i sees itself as a Swiss innovation community and dialogue platform for business and science. It brings together academic and business experts and aims to pave the way for collaborations that will secure Switzerland’s leading role as an innovative and successful market. Open-i is organised by NZZConnect, a branch of the NZZ based in Bern. The conference will take place on 27 November and tickets are available now.

  • New concrete reduces CO2 emissions in the construction industry

    New concrete reduces CO2 emissions in the construction industry

    Omya is a new partner in NEST, the modular research and innovation building of Empa and Eawag in Dübendorf. In the Beyond.Zero unit, which has been based there since the beginning of 2024, they want to test a cement-reduced concrete that they developed in a joint research project, according to a statement from Empa.

    Omya contributed its expertise as a globally active specialist in industrial materials. “The fact that we can now jointly develop sustainable building materials and test them directly in NEST under real conditions accelerates the transfer of innovations into climate-friendly construction methods,” said Empa Director Tanja Zimmermann.

    This innovative building material replaces up to 70 per cent of its clinker content with natural minerals. As Empa explains, this significantly reduces its CO2 footprint. “For a new type of concrete to be widely accepted, it needs to be tested in practice,” Empa researcher Mateusz Wyrzyklowski from Empa’s Concrete and Asphalt department is quoted as saying. “By using it in the NEST Beyond.Zero unit, we can comprehensively validate our cement-reduced concrete: from processing to durability.”

    The aim is a building material “that not only fulfils the ecological requirements, but also impresses in terms of workability, mechanical properties, volume stability and durability,” says Empa. The Beyond.Zero unit goes beyond the net zero target in construction. It pursues the vision that buildings can serve as carbon sinks in the future – in other words, they will have a negative CO2 balance on balance. The construction sector currently accounts for around 28 per cent of CO2 emissions in Switzerland.

  • Chatbots every third answer is wrong

    Chatbots every third answer is wrong

    In the international Newsguard analysis, ten of the most frequently used chatbots, including ChatGPT, Gemini, Perplexity and Claude, were tested for their responses to current news topics. The average error rate is 35 per cent, which is almost double that of the previous year. Questions on politics, health and international events are particularly affected. Many systems treat dubious sources like reliable news media and pass on disinformation even if it has been deliberately placed to deceive.

    Examples of propagated fake news
    The study prominently shows how often AI is manipulated with invented scandals and political quotes. For example, six out of ten systems falsely confirmed that Moldova’s parliamentary president had insulted his people as a “herd of sheep”. Behind this was a forgery including an AI-generated audio recording and a fake news site. In another case, a chatbot spread the rumour that the Ukrainian president owned real estate worth 1.2 billion dollars, a fictitious story based on an alleged whistleblower who never existed.

    Differences between the models
    While the AI assistant Claude is considered the most reliable provider with an error rate of just 10 per cent, Gemini has an error rate of around 17 per cent. Chatbots such as Perplexity, Grok, You.com, Mistral and Meta have an error rate of between 33 and 57 per cent. Today, the systems respond immediately in almost all cases. Even if they do not use enough validated information and accept a loss of quality.

    Source situation and willingness to provide information
    The increased error rate is mainly due to the willingness of the models to provide information. Where they used to prefer to say nothing at all, they now always provide an answer. Even from uncertain or manipulative sources. Chatbots run the risk of uncritically amplifying propaganda networks or social media disinformation, especially when it comes to news from regions with few reputable websites or political campaigns.

    Consequences for information security
    The automated, convincing dissemination of misinformation by AI chatbots increases the risk dynamics in the media landscape. Fact checkers warn that disinformation is subtly seeping into everyday life and shaping social awareness. Often difficult to recognise and therefore all the more consequential! Quality assurance for AI-supported information systems is therefore becoming a key challenge for the future of digital information.

  • Pioneering civil engineering

    Pioneering civil engineering

    With a total length of 266 metres, the bridge replaces an outdated structure from 1926 that no longer met the requirements of modern rail traffic. The central component is a gleaming white network arch with a span of 130 metres, which spans the border river Oder without supports. Instead of classic flat steel cables, 88 carbon tension members made of carbon fibre-reinforced plastic are used. These hangers were largely developed, tested and assessed at the Empa Institute in Dübendorf. They replace the steel segments weighing several tonnes and thus significantly reduce the overall weight of the supporting structure. An advantage for material efficiency and design freedom.

    Economic and sustainable benefits
    The innovative bridge technology made it possible to save around 600 tonnes of steel and 1,350 tonnes of reinforced concrete. A project-specific scaffolding solution was used in the construction process to ensure efficient assembly and welding of the bridge segments. Thanks to the high fatigue, tensile and corrosion resistance of the carbon fibre cables, both the maintenance effort and the service life of the bridge are positively influenced. A sustainability study shows that the use of carbon causes around 20 per cent less CO₂ emissions than a conventional steel structure.

    International appeal and future potential
    The railway bridge can be used by freight and passenger trains at speeds of up to 120 km/h and fulfils the highest safety standards. Extensive tests by Empa confirmed the fatigue strength of the material under real loads. The bridge has received several awards, including the Bridges International Award and the German Bridge Construction Prize. It is regarded as a pioneer for the use of high-performance composite materials in infrastructure construction.

    New aesthetics and symbolic significance
    The striking, elegant arch creates an architectural accent in the border region and emphasises the connection between the countries. The network arch bridge with carbon hangers symbolises both technical innovation and ecological responsibility. In future, it could serve as a standard for comparable major projects in European rail transport.

  • Swiss housing market continues to tighten

    Swiss housing market continues to tighten

    Die aktuelle Situation erinnert an die Jahre 2014 bis 2016, als eine längere Phase massiver Angebotsknappheit herrschte. Heute ist klar, dass kein kurzfristiger Ausgleich zu erwarten ist. Der Wohnungsbau bleibt auch in den kommenden Jahren hinter dem Wachstum der Haushalte zurück. Damit gehört die Schweiz erneut zu den europäischen Ländern, in denen sich die Wohnraumfrage zu einem zentralen Standortthema entwickelt.

    Belastung für Haushalte mit tiefer Kaufkraft
    Besonders stark trifft es Haushalte im unteren Einkommenssegment und des unteren Mittelstands. Während bestehende Mietverträge für rund 80 Prozent dieser Haushalte noch erschwinglich sind, zeigt sich auf dem aktuellen Markt ein deutlich anderes Bild. Nur gut 40 Prozent der neu angebotenen Wohnungen liegen in einem preislichen Rahmen, den diese Gruppen tragen können. In Regionen wie St. Moritz sowie in den urbanen Zentren und Agglomerationen fehlen passende Angebote nahezu vollständig.

    Wohnkosten steigen spürbar
    Ein Szenario aus dem Monitor verdeutlicht die Problematik. Würden alle Haushalte mit tiefer bis mittlerer Kaufkraft umziehen, stiege die durchschnittliche Wohnkostenbelastung von 29,1 auf 35,7 Prozent des Einkommens. Damit würde Wohnen für breite Teile der Bevölkerung klar zu einer finanziellen Überlastung. Bereits jetzt ist der Anteil der Mieterhaushalte, die ihre Wohnkosten nicht mehr im Budget halten können, von 2,6 auf 2,8 Prozent gestiegen. Noch moderat, aber mit klarer Tendenz nach oben.

    Fehlanreize auf der Angebotsseite
    Der Druck auf den Markt wird zusätzlich durch Investitionsmuster verschärft. Viele Investoren setzen auf Ersatzneubauten oder umfassende Sanierungen. Das stützt zwar die Bauwirtschaft, trägt aber kaum zur dringend nötigen Erweiterung des Bestands bei. Neue, bezahlbare Wohnungen kommen damit kaum auf den Markt. Entsprechend öffnet sich die Schere weiter zwischen günstigen Bestandes-Mieten und hohen Angebotsmieten, was die Verknappung zementiert.

    Bedeutung für Politik und Wirtschaft
    Die neue Analyse des BWO rückt die Frage der Wohnkosten im Verhältnis zum Einkommen in den Vordergrund. Für die kommenden Jahre bleibt absehbar, ohne strukturelle Ausweitung des Wohnungsangebots wird die Kluft zwischen Nachfrage und Angebot weiter wachsen. Für Wirtschaft, Gesellschaft und Immobilienbranche gehören damit innovative Wohn- und Baukonzepte ebenso zu den Schlüsselthemen wie regulatorische Anreize, um bezahlbaren Wohnraum effektiv zu sichern.

  • The Swiss champions 2025 at SwissSkills

    The Swiss champions 2025 at SwissSkills

    From 17 to 21 September, the BERNEXPO site was transformed into the centre of Swiss building technology. 62 participants from all parts of the country took on challenging competition tasks under realistic conditions. The young professionals competed against each other in the disciplines of heating installer, sanitary installer, plumber, ventilation system installer and in the three specialisations of building technology planning.

    The new Swiss champions are

    Innovation and practical orientation take centre stage
    The 35th Swiss Building Services Engineering Championships once again presented practical challenges. The young professionals had the opportunity to demonstrate their skills in front of a large audience and under time pressure on an area of almost 1900 square metres. Technical ability, creativity and teamwork were equally in focus. Skills that are becoming increasingly important in an increasingly digitalised and sustainable construction industry.

    Building technology experience inspires the public
    In addition to the competition, SwissSkills 2025 offered a broad supporting programme in Hall 19. Interactive zones such as the “Try-a-Skill” area invited visitors to experience technology for themselves and discover professions with their own hands. The careers fair stand, special Foxtrails and experience stations encouraged dialogue between young people, trainers and industry representatives. The direct dialogue and the opportunity to master challenges together make building technology a modern field of innovation.

    Significance for promoting young talent and the industry
    The successful Swiss championships impressively illustrate how attractive and future-oriented building technology is for motivated apprentices. With their skills and professional pride, the award-winning young talents look beyond the horizon and build a bridge to a sustainable and vibrant industry. For companies, educational institutions and the public, SwissSkills is an important impetus for further establishing building technology as a key area of the Swiss construction and energy transition.

  • Circular economy strategic upturn

    Circular economy strategic upturn

    The circular economy is becoming an integral part of corporate strategies in Switzerland. The proportion of companies that have anchored it in their corporate strategy has risen from 11 to 27 per cent within four years. Large companies in particular are showing great dynamism. More than half of companies with over 250 employees have already anchored it in their corporate strategy. Medium-sized companies follow with 39 per cent, while smaller companies lag far behind with 23 per cent.

    Implementation remains fragmented
    Despite clear progress in strategic awareness, operational implementation remains subdued. Only 15 per cent of companies generate more than ten per cent of their turnover with circular products, after only a marginal increase since 2020. Companies are similarly reluctant to invest. Only seven per cent invest more than ten per cent of their funds in circular economy measures. The breadth of activities is also limited, with only a few measures on average.

    Focus on energy instead of value chains
    Companies implement measures relating to energy consumption or the switch to renewable energies particularly frequently. Activities along the supply chains or in the use of raw materials are much rarer, even though these would be key levers for resource efficiency. According to study author Tobias Stucki, this means that a lot of potential is being wasted, especially as current geopolitical risks are once again putting dependence on raw materials centre stage.

    Sector and regional comparison
    There are striking differences between the sectors. Companies from the telecommunications, electronics and medical technology sectors are particularly active. Construction, real estate and personal services remain in the early stages of transformation. The regional picture is also mixed. Central and Eastern Switzerland lead the way in terms of strategic anchoring, while Ticino remains at the bottom. It is worth noting, however, that Ticino companies perform well above average in terms of their share of turnover with circular products.

    Political and legal framework
    Politicians have significantly expanded the framework conditions for the circular economy in recent years. It has been explicitly enshrined in the Environmental Protection Act since 1 January 2025. This has shifted the focus of resource conservation beyond waste management. Cantons such as Zurich and Bern have set the course with referendums and strategies. Zurich adopted a comprehensive circular economy strategy, while Bern anchored the objective in government guidelines and a new sectoral waste plan. Other cantons such as Basel-Stadt, Geneva and Vaud are also pushing ahead with their own initiatives.

    Circular economy as an issue for the future
    The study clearly shows that the strategic relevance of the circular economy is increasing in Switzerland. Nevertheless, consistent implementation remains largely limited to initial steps. The transition to a circular economy requires massive investment, far-reaching changes in supply chains and new forms of cooperation. This is the only way to ensure that the circular economy does not remain just lip service, but becomes a central pillar for the climate, resources and competitiveness.

  • Between vision and reality

    Between vision and reality

    Neom and “The Line” in particular were designed to diversify the country’s economy and create a global icon of modern urban development. The city as a 170-kilometre-long, linear megastructure without cars, powered entirely by renewable energy and urban superlatives, promised innovation and worldwide attention. However, it was announced at the end of 2024 that “The Line” would only be realised in a 2.4-kilometre section instead of the originally planned dimensions. Progress to date has been limited to access, infrastructure, initial zones and individual demonstration facilities. Little of the planned construction volume is visible in the desert.

    Financial and structural challenges
    The Saudi oil price is currently no longer sufficient to cover budget requirements and realise megaprojects on the scale originally planned. In the first half of 2025, the Kingdom recorded a budget deficit of around 25 billion US dollars. At the same time, foreign direct investment is stagnating, which is focussing responsibility all the more on the public investment fund PIF, whose reserves and profits have shrunk significantly in recent years. Cost explosions and operational gaps in project management have also cast doubt on the overall project. Internal studies now estimate the total cost of “The Line” at up to USD 8.8 trillion, many times more than ever before assumed.

    Division and redistribution
    The construction freeze not only meant that thousands of jobs were relocated or cancelled, but also that key sub-projects were assigned to new structures. The “Trojena” area, planned as a winter resort and location for the 2029 Asian Winter Games, was placed under the supervision of the Ministry of Sport. The industrial project “Oxagon” is now assigned to the state oil company Aramco. The luxury island “Sindalah” has been under the control of the tourism conglomerate Red Sea Global since 2024. The remaining active sub-projects will reduce Neom’s total share in the Saudi sovereign wealth fund to just six per cent. The massive staff cuts and the consolidation of strategies emphasise the serious changes.

    Consequences for Saudi Arabia’s future strategy
    The redimensioning of the flagship project is jeopardising central pillars of Vision 2030. Neither the planned symbolic leap into a hypermodern society nor economic independence from oil are secured for the foreseeable future. Major events such as the 2029 Asian Winter Games or the 2034 FIFA World Cup are being jeopardised. With its change of course, the country’s leadership is also demonstrating a greater awareness of economic limits and realities. This is a turning point that permanently relativises the claim to global leadership roles in urban planning and innovative state development.

  • Solar power stored seasonally for the first time in Kaltenbach

    Solar power stored seasonally for the first time in Kaltenbach

    At the post office in the village of Kaltenbach, which belongs to the municipality of Wagenhausen, surplus solar power from the summer months can in future be utilised in winter. This will be made possible by a SeasON demonstration system in the new post office delivery centre in Kaltenbach, Matica AG announced in a press release. The thermochemical process developed by the company in collaboration with Lucerne University of Applied Sciences and Arts utilises caustic soda for the loss-free storage of electricity and waste heat.

    When the electricity is stored, water is removed from the caustic soda solution and transferred to a separate tank. Concentrated caustic solution and separate water can then be stored at room temperature. If the stored energy is to be utilised, the concentrated caustic solution is diluted again with the separated water. The resulting mixing heat is supplemented by condensation heat. It is generated by vaporising the water in the closed system with the help of low-temperature heat from a heat exchanger.

    “For us and the team at Lucerne University of Applied Sciences and Arts, the realisation of the project in Kaltenbach is another important milestone on the way to the market launch of our innovative over-seasonal energy storage system SeasON,” said Matica CEO Marc Lüthi in the press release. “The experience gained from building the system, installing it and analysing the operating phase is essential for the efficient further development of our pioneering solution.”

    The Wagenhausen-based company installed its first demonstration plant in Frauenfeld in 2024. A third system is planned for spring 2026 in a housing estate in North Rhine-Westphalia.

  • Investment strengthens business location with 60 new jobs

    Investment strengthens business location with 60 new jobs

    Emmen-based SME Technik AG has broken ground on the construction of a new company building. With the construction of the new production facilities, the CNC manufacturing specialist aims to strengthen its location in the canton of Lucerne, according to a press release. With an investment of 7 million Swiss francs, a three-storey work and production building is being constructed. It will also create 60 new jobs.

    The building, with 1,200 square metres of production space and 1,100 square metres of office space, is primarily intended to optimise the CNC production of small parts or series for the aviation and railway industries. In a first step, two new CNC machines will be installed. The move is scheduled for spring 2026.

    The building, planned and realised by Cerutti Partner Architekten AG from Rothenburg, is designed for sustainability and energy efficiency. A solar system on the roof and air-to-water heat pumps were installed to ensure resource-conserving operation.

    “With the new building, SME Technik is creating modern workplaces that are attractive for both existing and future employees,” said Jan Kottucz, investor, owner and Chairman of the Board of Directors of SME Technik AG, in the press release. “At the same time, we can manufacture CNC parts for our customers with the highest precision and to Swiss quality standards in the modern production halls with new systems.” Ramona Gut-Rogger, Mayor of Emmen, sees the new investment by SME Technik as a “strong signal for the future of our business location.”

  • From the field: Why pole position counts in the region

    From the field: Why pole position counts in the region

    “I was hesitant at first,” says Rita Jeggli, real estate agent from Central Switzerland and owner of Perfect Living AG. “But after I booked Regional Highlight, I very quickly realized what a difference it makes that our properties are now placed at the top in our region and that visibility is improved as a result. Especially if the property is in a location that is not necessarily searched for at first glance. The inquiries came in noticeably faster, which of course makes me particularly happy!”

    Photo: Rita Jeggli

    The principle is simple but effective: properties advertised with Regional Highlight appear at the top of the search results on ImmoScout24 and Homegate for the duration of the campaign. “In the past, I often had to put my customers off if an advertisement didn’t generate the desired response,” reports Jeggli. “Today, the situation is different.” The exclusivity is particularly attractive, she adds. There are only three places available per district. Anyone who secures one of these benefits from a premium positioning that can make all the difference, particularly due to the intense competitive pressure. “The fact that there are only three spaces per district makes the product particularly attractive for us,” says Jeggli. “It makesPerfect Living AG more visible”.

    The offer is flexible: 1, 3, 6 or 12 months are available to choose from. This allows real estate agents to decide whether they want to position a property prominently in the long term or achieve a particularly high level of attention in the short term. “We really appreciate this flexibility,” says Jeggli. “Sometimes a property only needs a brief boost, sometimes we want to keep a prestigious property in the spotlight for longer.”

    Regional Highlight is part of SMG Real Estate’s Listing Performance portfolio and complements the Top Listing and Premium Top Listing products. While the latter offers nationwide reach and flexibility, Regional Highlight aims to have a lasting impact on the local market. In a real estate market characterized by strong competition and the recurring challenge of winning hard-fought mandates, Regional Highlight offers a decisive advantage: the right people become aware of an offer at the right time. For real estate agents like Jeggli, this means one thing above all: satisfied customers, faster deals and sustainable growth for their own company.

  • New dynamics for self-consumption communities

    New dynamics for self-consumption communities

    Primeo Energie is expanding its business for energy communities. The Basel-based energy company will take over the billing services for self-consumption associations (ZEV) from Energie Wasser Bern(ewb), Regio Energie Solothurn(RES) and AGROLA from the beginning of 2026, Primeo Energie announced in a press release. The three energy suppliers will continue to provide their customers with ZEV services, but will have these carried out by Prime Energie.

    “We believe in energy communities as an important element of the energy transformation,” said Primeo Energie CEO Cédric Christmann in the press release. “I am therefore all the more pleased that ewb, RES and AGROLA have placed their trust in us and transferred their ZEV services to us.” The takeover expands Primeo Energie’s Swiss-wide network to over 20,000 ZEV measuring points. The company’s growth strategy in the area of energy communities is intended to strengthen Primeo Energie’s position “as a leading provider of ZEV services”, according to the press release.

  • Strategic access to the German balancing energy market

    Strategic access to the German balancing energy market

    BKW is emphasising its growth ambitions in Germany by acquiring Munich-based Südvolt GmbH and its 20 employees, according to a press release. The Bern-based energy and infrastructure group is thus entering the German market for balancing energy and system services. Südvolt is a flexibility provider with access to all four German transmission system operators and thus to the balancing energy market.

    The company flexibly interconnects energy generation plants and industrial consumers in its virtual power plant in order to keep the grid stable. Its customer portfolio includes major and industrial customers from energy-intensive sectors as well as municipal utilities.

    As BKW emphasises in the press release, this acquisition is part of its Solutions 2030 strategy, which aims to expand its sustainable energy solutions by investing in energy storage and energy production.

    With this acquisition, “we are securing strategic access to one of the most important energy and flexibility markets in Europe”, said Stefan Sewckow, member of the Group Executive Board and CCO Energy Markets at BKW. “We are strengthening our position in the marketing of flexibility and expanding our international portfolio.” BKW already covers the entire value chain for the energy transition in Germany, from energy production and power line construction to building planning and project management, and is reportedly planning further growth in these areas.

  • Tradition meets innovation in façade renovation in Davos

    Tradition meets innovation in façade renovation in Davos

    The Hotel Schatzalp in Davos, which opened in 1900 as a luxury sanatorium, has been given a new façade with the support of architecture researchers from ETH Zurich. The building was constructed using digital aids. According to a statement from ETH, the contract for implementation was awarded to local timber construction company Künzli Davos AG and Instructive Construction AG(Incon.ai), which specialises in augmented reality technology. Incon.ai is a spin-off of the ETH and is based at Technopark Zurich.

    The designs for the reinterpretation were developed by a team led by Silke Langenberg, Professor of Construction Heritage and Monument Preservation at ETH Zurich, and architecture professors Fabio Gramazio and Matthias Kohler at the ETH Department of Architecture. The task for the architectural researchers was to preserve the appearance and integrate digital technologies into traditional craftsmanship and operational processes. “Based on the design logic of the old building, we reinterpreted the balustrades,” Fabio Gramazio is quoted as saying.

    Matthias Kohler sees this as a “fundamental change in the way we build”. The digital model replaces the double metre in traditional construction methods. The digital model created using augmented reality simplifies planning for tradespeople and allows people to use their dexterity and intuition. As Kohler emphasises, people retain control over the process.

    The wooden balustrades on the building had become outdated and no longer met today’s safety standards, he explains. In addition, the typical appearance of the Schatzalp with the loggias attached to the south façade had been impaired by numerous changes.

  • Photovoltaic system on company roofs in Aarau

    Photovoltaic system on company roofs in Aarau

    Over the next six weeks, HKG Engineering AG will be installing a photovoltaic system on the roofs of its own company buildings at the Aarau site. According to a press release, 184 high-efficiency modules are planned there, which will generate 93,000 kilowatt hours of electricity per year.

    The energy generated will be sufficient to cover the company’s own requirements in the offices and for charging electric vehicles. The system will also reduce the load on the neighboring Aarhof property, which is currently under construction.

    With this investment, HKG is sending out a clear signal for sustainable action. The aim is to reduce CO2 emissions in the building sector and reduce dependence on external energy.

  • Swiss freight metro is on ice

    Swiss freight metro is on ice

    The Cargo sous terrain(CST) underground freight transportation system has failed in its previously planned form. The private company Cargo sous terrain AG writes in a press release that its implementation is not economically viable at the present time. Private financing of the construction phase would require a different legal framework. The key is to embed the metro in an overall logistics system and to establish stable partnerships with the federal government, cantons and cities.

    According to CST, the technical and structural feasibility of the project has been proven. The plans for the underground logistics system with fine distribution in cities were confirmed as part of an independent review in spring 2025. It is now up to the authorities to proceed on this basis.

    CST remains in dialogue, but is shifting its focus: the company now wants to advise national and international organizations on urban logistics issues. In this context, CST must reduce costs and also cut ten jobs. According to the press release, CEO Christoph Späth deeply regrets this step. However, by restructuring, CST is setting the course for a sustainable future.

    “We do not currently have the resources to continue the organization with its current focus and are therefore adapting to the realities of the situation,” said Chairman of the Board of Directors Marco Rosso. It will take time until CST is firmly anchored in transport policy and can mobilize long-term investments.

    The plans for the freight metro had envisaged an underground network from Geneva to St. Gallen and from Basel to Lucerne with a branch from Bern to Thun. The first section of the freight metro from Härkingen to Zurich was originally scheduled to go into operation in 2031.
