  • Federal government adjusts cost limits for housing subsidies

    Federal government adjusts cost limits for housing subsidies

    The revision responds in particular to the high construction and transport costs in Alpine regions. Non-profit property developers in mountain regions now receive targeted subsidies, as it has been shown that the costs of building materials in these regions are significantly higher than in valley and midland areas.

    Increase in cost limits for affordable housing
    The cost limits for the construction, renovation and acquisition of housing were last adjusted in 2022. Since then, land and construction prices have continued to rise, making the new values necessary. This adjustment ensures that affordable housing continues to be subsidised and maintained.

    • Rental flats average increase of 5.3 %
    • Owner-occupied flats and detached houses Increase of between 4.0 % and 6.7 % depending on property type

    Promotion via guarantees and loans
    The federal government continues to promote housing indirectly, mainly via guarantees and the Fonds de roulement. The latter is managed by the umbrella organisations Housing Switzerland and Housing Cooperatives Switzerland and provides low-interest loans to non-profit property developers.

    Broad approval for the amendment to the ordinance
    The proposed amendment was submitted to the cantons and umbrella organisations for comment – all parties involved were in favour of the amendments. The new ordinance thus creates the basis for continuing to provide affordable housing even in times of rising construction costs.

  • Test planning for urban space at Winterthur railway station

    Test planning for urban space at Winterthur railway station

    The city of Winterthur and SBB developed the “Winterthur 2045” railway station expansion concept between 2019 and 2021. A new Vogelsang Nord terminus station was identified as the preferred solution to cope with increasing passenger volumes. At the same time, the platforms of the existing seven through tracks are to be widened.

    With these changes, the urban space around the station must also be rethought. Test planning is to analyse the potential and challenges and develop an overall strategy for the area around the station.

    Testplanning as the basis for a new master plan
    The test planning focuses on the areas of Bahnhofplatz and St. Georgenplatz, Rudolfstrasse and the southern railway station subway. The aim is to develop an overall urban development and transport strategy.

    • Quality of stay and climate adaptation in public spaces
    • Reorganisation of bus stops for better traffic routing
    • Optimisation of pedestrian and bicycle traffic
    • Categorisation of other modes of transport

    The area of the future Vogelsang Nord terminus station is excluded from this planning and will be dealt with separately.

    Involvement of the population and interest groups
    In order to ensure broad acceptance and viability of the solutions, the test planning is accompanied by a participatory process. Around 40 neighbourhood organisations, interest groups, political representatives and landowners will be actively involved in the design and discussion of the interim results.

    An electronic participation portal and participatory events are planned for the wider population. An initial echo chamber was held in February 2024 to clarify the planning brief.


    Starting signal for the new planning in 2025
    The City Council has approved a loan of CHF 780,000 to carry out the test planning. The planning will start in 2025 and is expected to last until 2026. It will form the basis for a new masterplan for the railway station urban space.

    The first masterplan has almost been implemented
    The first masterplan for Winterthur’s main railway station was developed back in 2009. Many measures from this were realised, including the redesign of the bus station with a mushroom roof, the northern pedestrian subway, new bicycle stations and the Neuwiesen traffic concept. The final work on the western side of the station should be completed by summer 2025.

    With the new test planning for the station urban space, Winterthur is now setting the course for the coming decades. The aim is to create a modern, sustainable and functional urban space.

  • Rising prices and a tight rental market

    Rising prices and a tight rental market

    Zürcher Kantonalbank (ZKB) has published its annual market analysis and confirms the further rise in property prices. Following growth of 3.7% in 2023, prices rose by 3.3% in 2024. Even if the pace has slowed slightly, the trend remains clear: residential property prices in Zurich have risen 2.5-fold in 20 years.

    It is interesting to note that despite lower interest rates, the expected stronger price increase failed to materialise. Demand was more subdued, particularly for new-build properties, which take longer to sell. Nevertheless, ZKB registered an increase in transactions in the second half of 2024, which indicates that demand is picking up again.

    Increasing shortage on the rental flat market
    The tense situation for rental flats continued in 2024. For the first time, the ZKB found that the number of sales advertisements was slightly higher than the number of rental offers – a sign of the continuing dwindling capacity on the Zurich rental market.

    Although the shortage was not quite as drastic as feared, ZKB anticipates a further decline in vacancies in 2025.

    Rents are also rising for existing tenants
    Rents in Zurich rose by an average of 4.5% in 2024 – a significant increase compared to the Swiss average of 3.3%. It is particularly noteworthy that not only new lettings but also existing tenancies were affected by increases.

    This trend is directly attributable to the reference interest rate increases from 2023, which had a delayed impact on rents. In the third quarter of 2024, existing rents in Zurich were 5.4 % higher than in the previous year, while they only rose by 3.3 % across Switzerland. The increase was even higher in the Lake Geneva region.

    Institutional landlords utilised their scope for rent increases more intensively than private owners. However, there are signs of a trend reversal: as the reference interest rate will fall in March 2025, many tenants are likely to demand a reduction in their rent.

    The Zurich property market therefore remains a dynamic field with rising prices for owners and increasing challenges for tenants.

  • Housing situation of older people in Switzerland

    Housing situation of older people in Switzerland

    Low residential mobility despite changing needs
    The majority of over 75-year-olds remain in their homes despite changing housing requirements. Only 5.1 per cent of this age group moved in 2022. The reasons for this are long-term, favourable rental agreements, central residential locations and emotional attachment to the home. High market rents and relocation costs also act as a deterrent. If a move does take place, it usually remains within the region or leads to a care facility.

    Barriers in older residential buildings make everyday life more difficult
    Over 60 per cent of people over the age of 66 live in buildings that are not barrier-free. Stairs, narrow doors or a lack of lifts can make everyday life more difficult and increase the risk of falls and health problems. Necessary renovations are often difficult to realise.

    Loneliness as a key challenge
    77 per cent of older people live alone or with people of the same age, which increases the risk of social isolation. Older women, who are more likely to be single, are particularly affected. Loneliness has a negative impact on physical and mental health and increases the need for support in everyday life.

    Barrier-free housing and better support
    The study recommends better integrating older people into the regular housing market and creating barrier-free housing in a targeted manner. In addition to age-appropriate renovations, new forms of housing close to care facilities are needed. Social networks and support services should also be expanded to enable people to live independently.

    Data-based findings for the future
    The study is based on extensive data analyses on residential buildings, households, income and tenancies. These allow precise insights into the housing situation of older people and provide a scientific basis for future measures.

  • Potential and challenges of new living concepts

    Potential and challenges of new living concepts

    The focus is on self-built residential units, which are often built in large halls and are shared by groups or individuals. Residents attach importance to sustainable and individualised living, foregoing excessive private space and sharing communal areas instead.

    The projects analysed in Zurich and Bern show that these types of housing use significantly less living space per person than the Swiss average. The high degree of flexibility in the interior design allows for individual customisation, but also entails high time and financial costs.

    Legal framework and challenges
    Clear but flexible framework conditions and supportive guidance from property developers and authorities are crucial for the successful implementation of these concepts. Building law hurdles and financing issues in particular require customised solutions to make such projects economically viable.

    Innovative niche solutions with potential
    Although these forms of communal living currently represent a niche, they offer exciting approaches for a more sustainable and diversified use of living space. However, their long-term potential for the affordable housing market remains to be seen.

    The study was conducted by the OST and FHNW universities of applied sciences in collaboration with the BWO, the Solidarity Fund Foundation, the Migros Culture Percentage and other partners. It is part of the research focus areas “Affordable housing” and “Adapting the housing stock to changing needs”.

  • ETH Zurich and HSG strengthen Swiss industry

    ETH Zurich and HSG strengthen Swiss industry

    The alliance brings together leading companies such as Roche, Nestlé, Schindler and Endress Hauser, which are funding the project with CHF 2.1 million over three years. The centrepiece is the Circle of Scholars, a network of six doctoral students who are researching topics such as artificial intelligence in production, sustainable manufacturing and global production networks together with industry partners.

    “With the Manufacturing Alliance, we are creating a platform that actively involves industry partners in research,” emphasises Prof. Dr Thomas Friedli (HSG). Prof. Dr Torbjörn Netland (ETH Zurich) adds: “Our doctoral students work on real problems from day one – this helps industry and promotes young talent.”

    Swiss manufacturing sector in focus
    HSG studies show that Swiss companies are increasingly relocating their production capacities back to Switzerland in order to benefit from innovation, stability and high quality. The Manufacturing Alliance aims to support this trend.

    Invitation to collaborate
    The Alliance invites companies of all sizes to participate. The partners benefit from practical solutions, scientific expertise and an exclusive industry network. Nestlé and Johnson & Johnson are already among the sponsors.

    “Switzerland plays a key role in pharmaceutical production,” says Leila Schwery (J&J). “This collaboration will not only strengthen the industry, but also bring significant benefits to society.”

  • Reuse of blind actuators

    Reuse of blind actuators

    Griesser is giving old JAX actuators a second life. These blind actuators, which are part of Griesser’s top-selling KNX sun shading control system, will be repaired with immediate effect, according to a statement from the sun shading specialist. They will then return to the economic cycle. They are now available for customised configurations on the MyGriesser online platform.

    The KNX variants with their JAX actuators are among Griesser’s national and international bestsellers. With its latest measure to “increase sustainability”, the company wanted to “start where we can achieve the greatest impact”, according to its CEO Urs Neuhauser. That’s why the choice fell on Griesser KNX control solutions.” The promise of quality also applies after the repair, which is why all repaired actuators come with a one-year guarantee. In addition, the other services also apply to the repair objects.

    The project will initially be launched in France. Other Griesser locations are also planned at a later date.

    As Griesser emphasises, the company has long been committed to the circular economy. For example, its aluminium has contained a high proportion of recycled material for several years. With the launch of Green Aluminium in 2024, CO2 emissions per kilogramme are to be reduced by up to 30 percent. According to the information provided, this greener aluminium will initially be used in the window shutter range.

  • Disentis/Mustér gets large-scale photovoltaic system

    Disentis/Mustér gets large-scale photovoltaic system

    Axpo Solutions AG from Baden and Bergbahnen Disentis AG are planning to realise a large-scale photovoltaic plant with a capacity of over 10 megawatts peak in the Grisons municipality of Disentis/Mustér. The two partner companies are currently founding the power plant company Ovra Solara Magriel AG, based in Disentis/Mustér, to construct and operate the plant. The project, which is based on Article 71a of the Energy Act, the so-called Solar Express, has now received the approval of the government of the canton of Graubünden, the cantonal administration announced in a press release. The voters of Disentis/Mustér had already given the plan the green light in 2023.

    The plant is to be built on an area already used for tourism at an altitude of around 2100 metres above sea level. The plan is to install 20,750 solar panels on an area of around 13.5 hectares. The operators expect an annual electricity production of around 14.6 gigawatt hours, of which around 5.4 gigawatt hours will be generated in winter.

  • Innovative measurement technology facilitates structural inspection of reinforced concrete

    Innovative measurement technology facilitates structural inspection of reinforced concrete

    Researchers at the Swiss Federal Institute of Technology in Zurich(ETH) have developed a method for detecting corrosion in the reinforcing steel of reinforced concrete structures without having to break open the concrete. The method developed by mechanical engineer Lukas Bircher and his team is based on electrochemical measurements, the ETH reported in a press release. Specifically, the researchers have invented a probe consisting of two inflatable seals with electrodes in the centre. A water pipe is built into the associated cable.

    The probe is inserted into the drainage pipes, the seals are inflated and water is then fed into the sealed area. The water creates a connection between the electrodes in the probe and the soil through the holes in the drainage pipe. This creates an electrolytically conductive connection to the steel in the structure, which forms a localised electrochemical measuring point. “We use the measuring cell to record electrical signals, which vary depending on whether the reinforcing steel is corroded or not,” Bircher is quoted as saying in the press release.

    At present, the probe still has to be passed manually through the drainage pipes one by one to enable a comprehensive assessment of the condition of the steel. In the next step, the team wants to “automate the measurement more and make the inspection probe more robust”, explains Bircher. As the concept has already proved its worth, he will found a start-up called Talpa Inspection together with materials engineer Federico Martinelli-Orlando and civil engineer Patrick Pfändler.

  • BAUMAG 2025 sets new standards

    BAUMAG 2025 sets new standards

    Even before entering the four halls, the huge excavators and special vehicles on the outdoor area attracted everyone’s attention. The trade fair got off to an impressive start, more than fulfilling the visitors’ anticipation. Over 18,000 trade visitors from Switzerland and abroad flocked to Lucerne during the four days of the fair to be inspired by the latest innovations in the construction machinery industry.

    Strong players and lasting contacts
    With 200 committed exhibitors, the trade fair presented a wide range of innovative products and services. The companies used the platform to forge lasting business relationships and engage in dialogue with decision-makers from Germany and abroad. The high purchasing power of the trade visitors was reflected in numerous business deals.

    Impetus for the future of the construction industry
    Key topics such as digitalisation, sustainability, increasing machine efficiency and occupational safety dominated the trade fair and underlined its importance as a driving force for the industry. Trade fair organiser André Biland and Exhibition Director Andreas Hauenstein emphasised the continuous further development: “In order to meet the requirements of our trade visitors, we must always keep an eye on the ecological and economic challenges as well as the political framework conditions. We have been following this approach for two decades and the trade fair is now more important than ever for the construction industry.”

    Networking platform with real added value
    Customer proximity was and remains a key success factor for the trade fair. Despite advancing digitalisation, personal interaction is essential for the industry. “The trade fair offers a valuable platform for maintaining existing contacts and establishing new business relationships. The personal support on site is appreciated by exhibitors and visitors alike,” says Hauenstein.

    Exciting competition as the highlight
    A special highlight was the semi-final of the Swiss Bricklaying Championships 2025, where ten talented craftsmen from Switzerland put their skills to the test. Six of them secured their place at SwissSkills 2025 in Bern, an exciting competition that impressively demonstrated the expertise and passion of the participants.

    Outlook for BAUMAG 2027
    With its proven concept and new impetus, the next BAUMAG will once again inspire the construction industry from 21 to 24 January 2027. Trade visitors can look forward to a versatile and future-oriented trade fair that will continue to offer the perfect setting for innovation, dialogue and sustainable business relationships.

  • Vaud economy between recovery and uncertainty

    Vaud economy between recovery and uncertainty

    Global economic tensions have increased in recent months. The OECD and the Swiss State Secretariat for Economic Affairs (SECO) point to risks, particularly from the new US administration and the unclear relations between Switzerland and the EU. While the US economy is growing more strongly than expected, the European economy remains weakened by structural challenges. The strong Swiss franc is slowing down export-orientated sectors, while domestic demand remains a stable pillar of the economy.

    Construction industry benefits from interest rate cuts
    The Swiss National Bank (SNB) has eased its monetary policy and lowered the key interest rate from 1.75% to 0.5%. This measure is creating a favourable investment climate, particularly in the construction industry, which is benefiting from falling financing costs. Forecasts for Switzerland as a whole predict growth of 1.5% this year and an acceleration to 1.7% next year.

    Sector development mixed picture
    While the industrial economy continues to be challenged, other sectors are showing mixed developments. The retail and hospitality sectors are struggling with a weak business climate, while the service sector is showing positive momentum. Particularly strong growth is forecast for the chemical and pharmaceutical industries, business services and the financial sector. The machinery and watchmaking industry could also benefit from the economic recovery in the medium term.

    Stabilisation with uncertainties
    The Vaud economy is looking forward to a year of opportunities, but also challenges. While key sectors are likely to benefit from a sustained recovery, geopolitical and currency policy uncertainties remain risk factors. The decisive factors will be how international trade relations and the domestic economy develop and the extent to which companies are able to react flexibly to changes.

  • Potentials and challenges of repurposing

    Potentials and challenges of repurposing

    Technical and economic challenges
    The conversion of commercial buildings into residential space requires considerable structural adjustments. Building depths, lighting conditions and infrastructure pose challenges that require high levels of investment. At the same time, conversion can be economically attractive if the rental potential for residential space is higher than that of office space. Creative concepts such as modular building elements or alternative living models such as co-living can facilitate realisation.

    Legal hurdles and political factors
    Building regulations, zoning plans and the NIMBY phenomenon (Not In My Back Yard) can delay or prevent projects. Early dialogue with authorities and residents can help to minimise resistance. In addition, politicians are increasingly willing to adapt the regulatory framework in order to facilitate conversions.

    Innovative practical examples
    Successful projects such as the conversion of the Rennbahnklinik in Muttenz or the pilot project on the former ZWHATT industrial site in Regensdorf show that sustainable living space can be created through flexible concepts, reduced construction costs and intelligent space solutions.

    Future prospects
    Conversions offer great potential for overcoming the housing shortage and for resource-saving urban development. Success requires innovative planning, political support and a co-operative approach between investors, authorities and the population.

  • Online tool for climate-neutral industrial processes

    Online tool for climate-neutral industrial processes

    Industry is facing the challenge of converting its processes from fossil fuels to renewable energies. High-temperature heat pumps offer an energy-efficient solution for temperature ranges from 100 to 200°C in particular. They can not only provide process heat, but also generate cooling at the same time, which makes them particularly attractive for many branches of industry.

    Interactive technology map for companies
    In the research project “Identification of industrial heat pumps for process heat”, Fraunhofer ISE has developed an online tool that provides companies with targeted support in selecting the right heat pump technology.

    The tool offers

    • Visualisation of the available heat pump technologies in the temperature range and output
    • Allocation of heat pumps to specific industrial processes (e.g. cleaning, drying, cooling)
    • Interactive retrieval options for process temperatures in various industries
    • Detailed fact sheets on circulation processes, compressor technologies and refrigerants

    A contribution to climate-neutral industry
    The online tool is part of the Fraunhofer research topic “Climate-neutral industry”, which supports companies on their way to a CO₂-neutral energy supply.

    This includes:

    • Optimisation of potential energy savings
    • Utilisation of industrial waste heat
    • Integration of renewable energies (e.g. photovoltaics for in-house power supply)
    • Storage solutions for heating, cooling and electricity

    Special attention is also paid to the treatment of industrial waste water, which not only contains waste heat but often also valuable residual materials such as metals or acids. These can be efficiently recycled using modern recovery technologies.

    Participate and contribute data
    The data pool of the online tool is constantly being expanded. Manufacturers of heat pumps and industrial companies can get in touch with Fraunhofer ISE to integrate their data into the platform and thus drive development forward.

    With this new digital solution, Fraunhofer ISE offers companies an effective tool for decarbonising industrial processes and increasing energy efficiency – a decisive step on the way to climate-neutral production.

  • Campus Platztor architectural competition launched

    Campus Platztor architectural competition launched

    In the first round of the competition, 73 applications were received, a surprisingly high number with high-quality reference projects. Decisive factors in the selection of the 16 offices were sustainability aspects, experience with similarly complex projects as well as urban planning and architectural quality. The selected teams come from St. Gallen, Zurich, Thurgau, Basel-Stadt and Geneva.

    Next steps and timetable
    Following the selection of the winning project in summer 2025, the canton and the university will further develop the project. Construction is scheduled to start in 2028 and the new campus is expected to open in 2031. The new campus will serve as a place of reflection and a meeting place and will blend harmoniously into the cityscape. The aim is to strengthen the university’s links with the city and its population.

    Realignment after project restart
    The current competition became necessary because the project selected in 2021 could not be satisfactorily developed further. The new process is now intended to create a viable concept that fulfils the high standards of architecture, sustainability and urban integration.

  • Ground-breaking ceremony for new production hall in Birr

    Ground-breaking ceremony for new production hall in Birr

    BRUGG Lifting, part of the BRUGG Group from Brugg AG, is starting the second expansion phase of its Industrial Park 2025 at the Birr site in January. The symbolic foundation stone for the new production hall 6 has now been laid with a ground-breaking ceremony in front of guests from local politics, business and the media. “With this project, we are sending out a strong signal of our innovative strength and our commitment to the region,” said CEO Markus Grüter in a press release.

    Production hall 6 will be equipped with two automated small parts racks and will also serve as a logistics centre. Three loading ramps will also be integrated. The investment totals 9.5 million Swiss francs. The construction work is expected to be completed in February 2026.

    In a first step, the new belt sheathing system – the production machine for the flat belts of the BRUbelt lift system – was built in the existing production hall. The costs for this totalled 3.5 million Swiss francs. At the same time, a new sliding rack was built to support production, providing storage space for over 1600 pallets for finished products, raw materials and semi-finished products. The lightweight hall was put into operation together with the mobile racking system on 6 December 2024.

    “The new production hall enables optimal integration of the new belt casing system and creates an efficient flow of goods with a modern logistics concept,” says Grüter. “The maintenance area will also be modernised to better integrate our apprentices.”

  • Baden Cantonal Hospital celebrates handover of keys for new hospital building

    Baden Cantonal Hospital celebrates handover of keys for new hospital building

    With the handover of the keys on 22 January, the KSB is now officially responsible for the new hospital building. The keys were handed over by actress Salomé Jantz in the role of Queen Agnes of Hungary, the KSB announced in a press release. The Habsburg queen donated a hospital to the town of Baden in 1349 and is the namesake of the current construction project.

    The new building was realised by a team from Ghisleni Partner AG under the leadership of owners Stefano and Maurizio Ghisleni. “By using a general planner, we were able to continuously optimise the project and incorporate the latest findings,” KSB CEO Adrian Schmitter is quoted as saying in the press release. “This means that our hospital will not be ten years old when it opens, but will be at the cutting edge of medical and technical development.”

    KSB has invested a total of 600 million Swiss francs in the eight-storey building. The new building, equipped with state-of-the-art medical and building technology, is due to open on 25 February. KSB will then move from the old to the new building.

  • New standard at JVA Bostadel

    New standard at JVA Bostadel

    The Bostadel prison, built between 1972 and 1977, is showing clear signs of wear and tear after decades. Structural modifications to increase earthquake safety, fire protection and energy efficiency are urgently needed to ensure the safety of inmates and staff. The comprehensive renovation project includes both the modernisation of the building technology and the construction of a new special department, which will serve as a temporary facility during the construction phase.

    Refurbishment during operation
    A central aspect of this project is the refurbishment during ongoing operations. The new building provides a temporary alternative solution during the renovation and is particularly geared towards the needs of older and long-term prisoners. This approach was developed in close cooperation with the Prison Concordat of Northwest and Central Switzerland and the Federal Office of Justice to ensure the smooth operation of the prison.

    Architectural innovation
    The winning project by Eggenspieler Architekten AG and architecture aménagement s.a. impresses with its well thought-out planning and architectural innovation. The extension creates additional outdoor areas and ensures a pleasant environment by optimising the lighting of the interior spaces. The result is the realisation of a modern and sustainable prison infrastructure.

    Efficient and sustainable project
    According to a rough cost estimate, the total costs amount to CHF 66.6 million, or CHF 50.35 million net after deduction of federal contributions, making the project efficient and sustainable. The involvement of the cantonal governments of Zug and Basel-Stadt guarantees the fulfilment of modern standards and requirements.

    Setting the course for the future
    Following approval by the cantonal governments and the forthcoming procedure in the cantonal parliaments, the project will be realised in stages. The extension is scheduled for completion by 2028 and the full refurbishment by 2031, preparing Bostadel Prison for the requirements of the coming decades.

  • Digital solution makes building renovations easier for owners

    Digital solution makes building renovations easier for owners

    HEV cooperates with Scandens. Founded in 2021 as a spin-off of the Swiss Federal Institute of Technology in Zurich(ETH), the company launched software around a year and a half ago that makes it easier to plan and implement energy-efficient building renovations. Thanks to the cooperation with HEV Zurich, the Scandens software is now also available to private homeowners for the first time.

    Using the Scandens internet application, which is based on artificial intelligence, they can check whether and which renovation measures make economic and ecological sense. According to the company, the machine learning algorithms used were developed at ETH Zurich and the Massachusetts Institute of Technology. The software combines them with the latest energy modelling techniques for digital twins and official planning standards.

    According to a press release from Scandens, the software displays over 500 renovation combinations and creates a plan that serves as the basis for implementation. “Our mission is to increase renovation rates in Switzerland and actively support owners in increasing the value of their properties,” Scandens co-founder Diego Sigrist is quoted as saying.

    According to HEV Director Albert Leiser, the association wants to provide “a future-oriented and practical solution” with this offer: “With Scandens, we can offer our members a very well-founded digital planning aid that saves time and promotes sustainable decisions.”

  • First construction phase in Unterfeld Süd in Baar starts in 2025

    First construction phase in Unterfeld Süd in Baar starts in 2025

    The owners Ina Invest and Estella Invest and the developer Implenia decided in favour of a digital project competition in which a digital 3D model was submitted instead of physical models. This made the jury process much easier, as different levels and elements could be flexibly combined and analysed. The winning design for the first construction phase, a combination of the proposals from Enzmann Fischer Partner AG and ORT AG, impressed with its innovative floor plans and a well thought-out design of the open space that harmoniously combines living and working.

    Open space design as the key to the attractiveness of the neighbourhood
    The Unterfeld Süd neighbourhood will be enhanced by generous open spaces, which
    extend along the Stampfibach stream. An ecologically valuable green space is being created here that offers a wide range of uses. The central arrival square at the S-Bahn station will be transformed into an inviting place to meet and linger thanks to tall trees and green islands.

    High-rise building with a view to the future
    The 60-metre residential tower block in the first phase is impressive not only for its height, but above all for its well-thought-out floor plans and flexible room layouts. The generous windows offer impressive views from every flat, while the bay windows on the façade allow residents to enjoy both the outside and the inside of their own flat.

    Commercial building as a centre for dynamic companies
    The adjoining commercial building also focuses on flexibility. Two glazed inner courtyards create islands of light that can be used as break areas. With its flexible room structure, the building offers space for a wide range of uses – from small offices to larger rental spaces for anchor tenants.

    The second phase will provide affordable housing and flexible commercial space
    The second construction phase, the planning of which is already at an advanced stage, will focus on affordable rental flats and owner-occupied flats. The inner courtyard of the planned perimeter block development in the second phase will create opportunities for retreat and public meeting spaces in equal measure. The buildings along Nordstrasse are deliberately designed to minimise noise pollution. A referendum on the second stage will also be held in Baar in 2025.

    Sustainable architecture and flexible usage concepts
    The architecture of the buildings reflects the vision of a future-oriented neighbourhood. The combination of flexible living, versatile commercial space and well thought-out open spaces creates a lively and attractive cityscape. Particularly noteworthy is the combination of living and working, which is supported by well thought-out spatial concepts and attractive outdoor areas.

  • Space for the future “An der Aa”

    Space for the future “An der Aa”

    The “An der Aa” project aims to repurpose and densify the ZVB site. Key elements include increasing the living and working space, a modern infrastructure for public transport and emergency services and opening up the neighbourhood to the local population. Of the planned flats, 40% are to be offered at an affordable price in order to meet the demand for affordable housing in Zug.

    Infrastructure for mobility and emergency services
    In the centre of the new district, a state-of-the-art building will be constructed to house the Zug rescue service and the cantonal administration. The proximity to the new ZVB main base will enable synergies, for example in vehicle maintenance. The new infrastructure will meet the increasing demands of public transport and rescue services and contribute to future-proof mobility.

    Focus on quality of life
    The site is being densified and ecologically upgraded. The Siehbach stream will be uncovered and a barrier-free footpath integrated. Green spaces and public squares will enliven the neighbourhood and provide space for recreation. The Schleifendamm will be secured as a biodiversity-rich oasis for plants and animals and contribute to the quality of life in the neighbourhood.

    Legitimisation and broad support
    Work on the “An der Aa” project has been ongoing for 14 years, involving various stakeholders from politics, administration and the public. With 81.3% approval in March 2024, the people of Zug have given their support to the development plan. Construction is scheduled to begin in 2025 and be completed by 2032. Thanks to this broad support, the neighbourhood will become a flagship for innovative urban development in Zug.

    Future prospects
    The project will change the face of Zug and meet the growing demand for residential and commercial space. The new infrastructure will create capacity for a significantly higher volume of public transport passengers and secure the operation of the emergency services.

  • Collateral in the construction and property sector – What to look out for?

    Collateral in the construction and property sector – What to look out for?

    The usual means of security
    Collateral is ubiquitous in the construction and property sector. For the financing of land or residential property, mortgages (liens on real property) are in the foreground. Step-by-step transactions (e.g. the purchase of a plot of land or a flat) are usually secured with so-called promises to pay from banks. Abstract guarantees or sureties are then frequently used to ensure that construction work is carried out in accordance with the contract. Finally, it is also conceivable to hand over movable property as a pledge or to transfer (future) claims of one’s own company against third parties to a lender.

    Guarantees and sureties in particular
    With a guarantee, a bank or insurance company undertakes to pay the guarantee recipient an amount if certain conditions (e.g. a breach of contract) are met. If the bank/insurance company waives all defences and objections arising from the basic relationship, this is an abstract guarantee in accordance with Art. 111 CO. Such guarantees can be called with a mere notification, which is why they are often also called “guarantee on first demand”. In practice, such guarantees are used as performance, advance payment and warranty guarantees.

    In contrast, a surety is always dependent on the underlying transaction. The bank/insurance company is entitled to the same defences and objections as the principal debtor. The main case of application in practice is the joint and several guarantee, which is also specified in the widely used SIA-118 standard as standard security for liability for defects.

    The recipient of an abstract guarantee is in a better position and usually receives his money immediately. Guarantees are therefore expensive and the guarantor always requires security in the event of a claim. The need for security must be examined on a case-by-case basis and the form of the security must be weighed up.

    Guarantees – a world of formality
    Guarantees on first demand sound tempting because they are supposedly easy to handle. This can be deceptive: Firstly, the guarantee text must be checked, because not every guarantee is abstract. Then you need to keep an eye on the period of validity. When making a claim under a guarantee, the formal requirements in the guarantee document must be meticulously observed, otherwise payment may be refused (so-called guarantee rigour). Another decisive factor is the way in which the claim must be submitted to the bank/insurance company and with which declaration (directly, via a correspondent bank, etc.). It is worth checking this in advance.

    A guarantee is utilised – what needs to be done?
    When the guarantee is issued, it is important to ensure that the bank/insurance company undertakes to provide notification in the event of a claim. This gives the party against whom the guarantee has been issued the opportunity to have the bank/insurance company prohibited from making the payment by court order. However, it should be borne in mind that the courts will only prohibit a payout if the claim is clearly an abuse of rights. The hurdles are so high that payouts are very rarely prohibited.

  • Merger in timber construction secures jobs and expertise

    Merger in timber construction secures jobs and expertise

    The timber construction company Blumer Lehmann, based in the St.GallenBodenseeArea, has announced the takeover of Hächler Holzbau, as detailed in a press release. From 1 April 2025, Hächler customers will be served from the company’s headquarters in Gossau. All existing and new orders will be processed in the existing workshops. These will remain at the Neuenhof site.

    The takeover is intended to bundle the “first-class timber construction expertise” of both companies “into an impressively diverse range of services for sustainable timber construction solutions”, according to the statement. The focus is on classic timber constructions and prefabricated timber construction projects.

    With this step, a successful successor solution has also been found for Hächler’s timber construction division, the Wettingen-based Hächler Group announced in a separate press release. A solution for his succession had been worked on together with Managing Director Günter Ebner for some time. “The focus was on the secure future of our employees and maintaining our long-standing customer relationships.”

    According to the company, Blumer Lehmann specialises in solutions for the timber industry and in timber and silo construction. 500 employees at four locations provide craftsmanship services for a wide range of customer projects worldwide.

    Hächler Holzbau realises “small jobs and complex construction projects” using wood. According to the company, all employees will be taken on. Vocational training will also be continued.

  • New school infrastructure in Zofingen takes shape

    New school infrastructure in Zofingen takes shape

    The building construction for the new secondary school centre in Zofingen has been underway since June 2024. As the construction company responsible, STRABAG, has now announced, the basement and the first floor with classrooms are already in place. In the excavation pit next to the gymnasium, the specialised civil engineering team has completed the groundwork by installing the bored piles and constructing the retaining walls.

    At the same time, employees from Verkehrswegebau Obergösgen are laying the service lines. The structural engineering work should be completed by the end of June 2025. The finishing work will then begin, according to the information provided. The building will be put into operation at the start of the 2027/2028 school year.

    STRABAG describes the ten concrete beams for the gymnasium ceiling, which were lifted into place in mid-November, as a “spectacular highlight”. Each of them was 29 metres long and weighed 60 tonnes. Other prefabricated elements were also installed. They were reportedly planned immediately after the contract was awarded in order to be ready for use on time.

    Now that the beams for the new triple gymnasium have been moved into place, the structural engineering staff, led by site manager Daniela Huonder and foreman Vincenzo Tafaro, are currently busy shuttering, reinforcing and masonry work on the other floors.

  • Foldable and reusable formwork revolutionises concrete construction

    Foldable and reusable formwork revolutionises concrete construction

    Unfold Form is the name of the lightweight and reusable formwork for vaulted concrete structures. It was developed by architecture doctoral student Lotte Scheder-Bieschin in Philippe Block’s ETH research group. According to an ETH report, it saves up to 60 per cent concrete and up to 90 per cent steel compared to conventional ceilings.

    Unfold Form consists of thin, flexible plywood strips. They are connected to each other by textile hinges and can be unfolded like fans. Four such moulds are quickly and easily joined together in a wooden frame to form a load-bearing formwork with spikes. The concrete is poured on top. “The concrete absorbs these corrugations as ribs,” says the inventor. “These ribs help to transfer loads.”

    Once the concrete has hardened, the formwork can be removed from below, folded up again and used again. According to the information provided, the entire system for the prototype weighs just 24 kilograms, but can carry up to 1 tonne of concrete.

    “In addition to the material, you only need a template for the mould and a stapler.” The material for the prototype cost 650 francs. As the researcher emphasises, the formwork can be produced and set up without specialist knowledge or high-tech. This means it can be used worldwide, even with limited resources, for example in developing countries. The demand for new buildings is particularly high there.

    The second prototype was cast on site by the South African partner company nonCrete, which is committed to sustainable buildings and affordable housing. “The innovative formwork system,” says Scheder-Bieschin, “will one day be used to build high-quality, dignified and sustainable homes in South African townships.”

  • St.Gallen freight station site underestimated development area

    St.Gallen freight station site underestimated development area

    Urban areas are under increasing pressure. Rising population figures and limited space call for innovative solutions. Areas behind railway stations in particular often remain unused, although they offer valuable potential for urban development. One example of a successful conversion is Europaallee in Zurich. However, while new urban neighbourhoods are already being created in many places, the future of the St.Gallen freight station site is still open.

    Its development has been discussed for years, but different interests and perspectives have so far prevented a concrete realisation. This was the starting point for the course “Building the future – the importance of sectors for urban development”, which brought together architecture students from ETH Zurich with economics and sociology students from the University of St.Gallen.

    Interdisciplinary collaboration as the key to success
    The course combined architecture, urban sociology and economics to create a new approach to urban planning. “Architects of the 21st century learn from the building methods of the 20th century in order to develop sustainable models for the future,” explains Prof Momoyo Kaijima from ETH Zurich.

    The collaboration with sociologists and economists resulted in practice-oriented research that took into account not only urban planning concepts, but also social and economic aspects.

    Experiencing urban planning from new perspectives
    The students began their investigation with guided walks through the freight depot area, inspired by the sociologist Lucius Burckhardt’s “Spaziergangswissenschaften”. This method enabled them to experience the space not just as a planning object, but as a lived social place.

    “The study made it clear that even inconspicuous or derelict areas can play a decisive role in urban dynamics,” reports HSG student Livius Schönle.

    From observation to concept
    Based on interviews, observations and data analyses, the participants developed so-called “actor network drawings”, which they used to visualise complex relationships between the use of space, social groups and economic interests. Art painter Walter Dick also played a role in this, introducing the students to the basics of hand-drawing in order to visually represent their analyses.

    “The concrete experiences from the interdisciplinary collaboration show how important it is to be aware of the different ways of thinking,” emphasises Dr Niklaus Reichle from the University of St.Gallen. “Only if we think outside the disciplinary box can social challenges in dealing with space be tackled in a meaningful way.”

    Visions for sustainable urban development
    The students’ concepts ranged from multifunctional residential and working neighbourhoods to sustainable green spaces that integrate new recreational areas into the city. Some teams developed ideas for mixed-use buildings that combine social housing with commercial space, while others developed strategies for careful densification through innovative construction methods.

    A central theme was social integration: how can the freight depot area serve as a connecting element between existing neighbourhoods? How can open spaces be created that are both ecologically and socially valuable?

    Urban development as a joint task
    The research results emphasise that successful urban development requires more than just structural measures. Economic, social and ecological aspects must be considered together. The collaboration between ETH and HSG shows how different disciplines can learn from each other in order to make urban spaces sustainable and fit for the future.

    The city of St.Gallen could benefit from these findings: The freight yard site offers enormous potential for innovative neighbourhood development if the right course is set.

  • Revolution in materials technology

    Revolution in materials technology

    Epoxy resins are indispensable for numerous industrial applications, from adhesives to coatings and composites. While conventional two-component epoxy resins require precise mixing and fast processing, one-component epoxy resins offer simplified handling and consistent quality.

    However, previous solutions had weaknesses. They could often only be stored at low temperatures and had insufficient flame-retardant properties. This limited their potential applications in safety-critical areas such as the construction, electronics and telecommunications industries.

    Breakthrough from Korea
    A research team from the Korea Institute of Science and Technology in collaboration with Sungkyunkwan University has overcome these hurdles. Under the leadership of Dr Jaewoo Kim and Professor Chongmin Koo, they developed the “Epoxy/MXene One-Component Solution”, a combination of epoxy resin, a new type of latent hardener and the two-dimensional nanomaterial MXene.

    This innovation enables a storage stability of over 180 days at 60 °C, a significant advance compared to previous products, which lose their properties within 40 days at room temperature of 25 °C.

    MXene as the key to stability and safety
    MXene, a state-of-the-art nanomaterial, not only improves the thermal and mechanical resistance, but also makes a decisive contribution to the flame retardancy (V0 class) and electrical conductivity of the new epoxy resin. This opens up a wide range of applications in the high-performance industry, particularly for electromagnetic shielding materials, industrial coatings and adhesives.

    Industrial applications and future potential
    The combination of extended durability, improved safety features and easy handling makes the new 1-component epoxy resin particularly attractive for industries with high demands on material stability and fire protection.

    Possible areas of application

    • Electronics: Protective coatings for components and printed circuit boards
    • Construction industry: flame-retardant adhesives for safety applications
    • Telecommunications: high-performance materials for antennas and shielding housings

    With this innovation, the South Korean research team could have a lasting impact on materials technology and set new standards for single-component epoxy resins.

  • New measurement technology detects corrosion in reinforced concrete without intervention

    New measurement technology detects corrosion in reinforced concrete without intervention

    Retaining walls, tunnels and bridges made of reinforced concrete characterise the Swiss cityscape and infrastructure. However, many of these structures are already several decades old – and chemical changes in the concrete affect the steel used. If the reinforcing steel begins to rust, the structure loses stability. The damage is particularly problematic in inaccessible places where conventional testing methods fail.

    Electrochemical measurements as a new solution
    Until now, engineers have had to break open parts of the concrete to check for corrosion damage. A time-consuming and often inadequate procedure. Talpa has developed a new method that works via drainage pipes. A special probe is inserted into the pipe and uses electrochemical signals to measure the likelihood of corrosion in the surrounding reinforced concrete.

    “This has never been done before,” explains Lukas Bircher, one of the developers. “Previously, you had to remove entire concrete surfaces to find damage and could still easily miss a critical area.” With the new technology, entire sections of wall can now be systematically tested without destruction or costly construction work.

    Measurements during operation – without a construction site
    The method has already been successfully tested, including on a 200 metre-long retaining wall in Zurich-Höngg. The principle is a probe that is inserted into the drainage pipe and fixed in place with inflatable seals. The system then directs water into the measuring area, creating a conductive connection between the electrodes of the probe and the steel in the concrete. Based on the recorded electrical signals, the team can recognise whether and to what extent corrosion is present.

    A new measurement is taken every 25 centimetres to record the condition of the entire section of wall. “This allows us to specifically identify those areas that actually pose a risk,” says Bircher. “This not only saves time, but also high costs for unnecessary interventions.”

    50 years after the construction boom – the need for renovation is growing
    Many of the reinforced concrete structures affected today date from the boom period between 1960 and 1980. Retaining walls from the 1970s in particular often contain cavities that favour corrosion. Previously, damage had to be identified by means of time-consuming spot checks, with a high risk of overlooking critical areas. The new method offers a comprehensive and reliable analysis for the first time.

    From research to start-up Talpa-Inspection
    The technology has such great potential that Bircher founds the start-up Talpa-Inspection together with two colleagues. The name “Talpa”, Latin for “mole”, symbolises the innovative way of making deeply hidden damage visible. Supported by an ETH Pioneer Fellowship, the team is further developing the technology and preparing to enter the market.

    Future prospects, automation and scaling
    The measurement is currently still partly manual, but the team is already working on an automated version. The aim is to make the probe more robust and further accelerate the measurement process. Demand is high. In Switzerland alone, there are over 1,000 kilometres of potentially affected reinforced concrete structures.

    “Our method offers a real opportunity to extend the service life of existing structures,” says Bircher. “We hope that it will soon establish itself as a standard procedure for structural diagnostics.”
