  • A model project for Switzerland Ecological upgrading of the River Sihl

    A model project for Switzerland Ecological upgrading of the River Sihl

    Over a century ago, rivers and streams were straightened and dammed in many places in Switzerland in order to provide flood protection and gain additional land. Today’s knowledge shows that this has had detrimental consequences for nature. These formerly dynamic and diverse watercourses have become ecologically impoverished and monotonous ribbons of water. The situation is similar in the Sihlwald, whose near-natural habitats for animals and plants have largely disappeared. Fish migration is also significantly impaired by these construction measures. The current revitalization project aims to restore dynamism and diversity to the river area.

    Focusing on the project section in Sihlwald
    The core of the revitalization project is the river area at the Sihlwald terminus of the Sihltal-Zurich-Uetliberg railroad and the Zurich Wilderness Park Visitor Centre. With a length of around 1.8 kilometers, this section plays a key role in the Canton of Zurich’s revitalization planning and is a top priority. The aim is to enhance the ecological value of this section of the river and thus create new, high-quality habitats that are particularly important for animals and plants.

    Through the planned revitalization, those responsible hope to take on a pioneering role in the near-natural development of watercourses and at the same time increase the local recreational value for the population. This integrative approach should serve as a model for similar projects in other regions of Switzerland.

    More dynamics, more structure, more habitats
    Most of the Sihl’s current bank obstructions will be removed. New structural elements such as islands, large stones and more branches and rootstocks will make the river more diverse and dynamic than it is today. Thanks to a new fish ramp, the Sihl will be more passable for fish and other aquatic life. New ponds as well as wet meadows and rough pastures are also planned. All of these measures will create a variety of new habitats for animals and plants, thereby increasing biodiversity.

    On the right bank of the river, a zone will be created that will be reserved for nature. This quiet zone in the popular local recreation area will provide protected retreats for animals. This will benefit the kingfisher, for example, which is very sensitive to disturbance during the breeding season.

    Improving the quality of life
    The revitalization also makes the river area more attractive for people. Opportunities to spend time by the river and accessible ponds offer visitors insights into nature.

    To create a quiet zone for nature on the right bank, the current path below the visitor center will be moved to the left bank of the river. The footpath and cycle path will be separated there. This will give both road users more space. Along the new, varied footpath on the left bank of the river, the vegetation will be repeatedly thinned out. This provides interesting views of the wild riverbank opposite. Small footpaths lead to the river and to natural seating areas by the water. The bridge at the visitor center will be dismantled.

    Joint project between the canton ofZurichand SBB
    The revitalization of the Sihl is a joint project between the canton of Zurich and SBB. It is part of the environmental measures as part of the new concession for the SBB’s Etzelwerk hydropower plant. The ewz naturemade star fund and the federal government are also making financial contributions.

  • Change of management at SVIT Switzerland decided

    Change of management at SVIT Switzerland decided

    The Assembly of Delegates of the SVIT member organisations took place in Lucerne on 20 June 2024. It was decided that Michel Molinari, currently Vice-President of SVIT Switzerland, will take over the office of President from Andreas Ingold in 2025. Jean-Jacques Morard, also Vice-President, will be replaced by Cécile Berger-Meyer. David Zumsteg will succeed Michel Molinari as Vice President. Andreas Dürr will also hand over his seat to Boris Grell in 2026. Last year, Gabriel Schmid was appointed to the Executive Committee as Chief Financial Officer. These new appointments mark the start of a comprehensive change of leadership in the umbrella organisation.

    Decision on sponsorship agreements
    In addition to the elections to the Executive Committee, the delegates voted on motions put forward by SVIT Eastern Switzerland and SVIT Central Switzerland. The motions called for SVIT Switzerland not to conclude any further advertising, sponsorship or other service agreements with Swiss Marketplace Group AG and its organisations. Existing agreements should be cancelled at the end of their contractual terms. The delegates approved these motions, thereby sending a clear signal in favour of a new direction for the association.

    Swiss Real Estate Forum as a supporting event
    The 2024 Delegates’ Meeting was embedded in the Swiss Real Estate Forum (SREF), which took place on the same day. This forum provided a platform for personalities from politics, business and sport, including former Federal Councillor Ueli Maurer and former world goalkeeper Oliver Kahn, to discuss current issues in the property sector.

    With the decisions taken and the change in leadership that has been initiated, SVIT Switzerland is positioning itself for the future and providing important impetus for the further development of the association and the industry as a whole.

  • Real estate summit dedicated to digitalisation

    Real estate summit dedicated to digitalisation

    The Zurich Airport Region Economic and Location Promotion FRZ hosted its tenth Real Estate Summit in Dübendorf on 12 June. according to a press release, 650 guests from the construction and property industry gained insights into current trends and future industry developments. Under the motto “Human Power: People. Network. Success”, there were presentations on market trends, digital technologies and the future of construction.

    André Ingold, Mayor of Dübendorf, addressed the region’s development into a “dynamic economic centre” and highlighted the Innovation Park Zurich. This will create more than ‘000 jobs in the short term, with 12,000 to 15,000 planned in the medium and long term. He went on to talk about the motto: Despite technological advances and the use of artificial intelligence (AI) in the real estate industry, people remain the focus.

    FRZ Managing Director Rahel Kindermann Leuthard emphasised the importance of the FRZ business network as a “driving force for location development” and presented construction projects. Referring to the motto of the summit, she addressed the growing complexity. This has “reached a level where success is only possible together with others”.

    Lydia Naef, Chief Real Estate Officer at Flughafen Zürich AG, used examples from Zurich Airport’s real estate management to illustrate how construction projects can be optimised with human performance and digital technology. She paid particular attention to the digital technologies used to manage the entire life cycle of property projects. Building information modelling, the Internet of Things, AI and virtual reality could help to reduce costs and increase efficiency.

  • Sustainable CO2 storage in the concrete plant

    Sustainable CO2 storage in the concrete plant

    The gravel and concrete plant of Ch. Gerster AG is the first company in Liechtenstein to offer the Neustark process for storing CO2. The CO2 is mineralised on site in Gerster’s concrete granulate called granulite, which in turn is obtained from demolition concrete. This granulate is also a component of Gerster’s Rainulit recycled concrete. “We are thus presenting a solution for reducing CO2 emissions in the construction industry,” says a statement from Gerster.

    In the plant developed by the Bern-based ClimateTech company Neustark, gaseous CO2 of biological origin reacts with lime produced during cement production. This mineralisation process produces limestone again. As the CO2 would only be released again at a temperature of over 700 degrees, it remains permanently bound in the limestone and is therefore permanently removed from the air. According to Neustark’s own press release, the Ch. Gerster AG plant can permanently store 100 tonnes of CO2 per year.

    Neustark now has 19 separation and storage plants, transforming the world’s largest waste stream – demolition concrete – and other mineral waste materials into carbon sinks. According to its own figures, the spin-off from the Swiss Federal Institute of Technology in Zurich(ETH) has so far permanently removed 1719 tonnes of CO2 from the air. Its goal is to reach 1 million tonnes by 2030.

  • Cement revolution thanks to mother-of-pearl structure

    Cement revolution thanks to mother-of-pearl structure

    Unlike glass, wood and steel, cement is naturally brittle and not very flexible without reinforcements. This considerably limits its possible uses in load-bearing structures. Although there are already methods for improving the fracture toughness and ductility of cement, for example through polymer, glass or metal reinforcements, these only slightly increase energy absorption and fracture resistance.

    A composite material modelled on mother-of-pearl
    The Princeton University team found that alternating layers of thin polymer and patterned cement paste increase ductility. The composite material developed mimics the structure of mother-of-pearl, a substance found in certain shells and known for its strength and flexibility. Mother-of-pearl consists of over 95% calcium carbonate and up to 5% organic material. This unique combination gives mother-of-pearl its remarkable mechanical resistance.

    Mechanisms of the mother-of-pearl structure
    Mother-of-pearl is a biomineral consisting of aragonite platelets connected by a soft biopolymer. This 3D brick mortar structure allows the platelets to slide and deform, absorbing energy and increasing toughness. This synergy between the hard and soft components is crucial for the remarkable mechanical properties of nacre.

    Applying the principles to cement composites
    The Princeton University researchers used conventional building materials such as Portland cement and polymers to develop a similar composite. They layered cement paste boards with polyvinyl siloxane, a flexible polymer, to create multi-layered beams. These were tested for crack resistance in a notched three-point bending test. The results showed that these composites achieved 17 times higher fracture toughness and 1791 per cent higher ductility compared to solid cement.

    Future prospects and optimisation
    The researchers plan to explore different soft materials for more resistant infrastructures and to optimise the groove shapes for better defect integration. In addition, production methods are to be further developed using integrated lamination laser processes or additive manufacturing. These advances could revolutionise the construction industry and significantly expand the use of cement in load-bearing structures.

    The newly developed cement composite, inspired by the structure of mother-of-pearl, offers a promising solution for improving the mechanical properties of cement. With its exceptional crack resistance and ductility, this composite represents a significant innovation that has the potential to transform the construction industry.

  • Legal need for action in the event of construction defects

    Legal need for action in the event of construction defects

    The current legal situation is proving to be disadvantageous for buyers of new builds and private developers. Problematic contractual clauses that have developed in practice put them at a considerable disadvantage. The existing law assumes two equally strong negotiating partners, which is not the case in reality. Professional contractors and sellers dictate the terms of the contract, while private developers have no negotiating power due to the high demand in the real estate market. This “eat or die” mentality puts them under massive pressure.

    The National Council’s proposals: Abolition of the separatenotice period
    The National Council has created a practicable proposal, the core of which is the abolition of the separate notice period for defects. Currently, buyers and builders have to observe two deadlines: the notice period and the limitation period. The notice period requires a detailed notification of defects to the right person within a short period of time. If this deadline is missed, buyers and builders lose all warranty rights. The limitation period is the second requirement. The abolition of the notice period would solve the main problem that many lose their statutory liability claims because they are unable to give notice of construction defects in good time. HEV Switzerland supported this decision by the National Council.

    The position of the Council of States: Extension of the notice period, but no abolition
    The Council of States recognizes the need for action to improve liability for construction defects, but maintains the notice period, albeit extended to 60 days. However, this extension does not solve the fundamental problem that private buyers and builders lose their rights in the event of defects if they do not comply with the legal requirements of a notice of defects within the deadline.

    No extension of the limitation period
    The Council of States is also adamant about the limitation period. The existing period of five years remains in place and can be shortened further by contract. The National Council had called for this period to be extended to ten years in order to do justice to the buyer’s claims for defects. For homeowners and condominium owners, the onset of the limitation period means that they can no longer enforce their rights in the event of construction defects and must bear the costs themselves. In view of the long service life of many building components, this short limitation period is problematic. HEV Switzerland is disappointed that private lay purchasers and building owners continue to be disadvantaged.

    Referral back to the National Council
    The bill will now be referred back to the National Council. HEV Switzerland remains committed to improving the legal situation of private home and condominium owners in the event of construction defects. The hope remains that further discussions and adjustments will lead to a solution that meets the needs and rights of private builders and property buyers.

  • Successful completion of the preliminary project for the Horw campus

    Successful completion of the preliminary project for the Horw campus

    The successful completion of the preliminary project for the expansion and renovation of the Horw campus brings the vision of a modern educational centre a significant step closer. The purpose of the preliminary project phase was to gain detailed insights into the development and cost structure of the construction project. Despite the expected additional costs due to external factors such as construction costs and sustainability-orientated measures, the original project costs of CHF 365 million have been largely confirmed.

    Cost development and influencing factors
    The analysis has shown that in addition to construction inflation, which accounts for around 18 per cent of the increase in costs, adjustments to VAT also have a significant impact. Further additional costs in the area of sustainability and project development as well as statutory sustainability certifications increase the financial framework. Total expenditure is now expected to amount to CHF 600 million, including reserves of around CHF 78 million. This sum is still in line with comparable projects of a similar scale in Switzerland.

    Relevance for education and the economy
    Government Councillor and Finance Director Reto Wyss emphasise the continuous monitoring and review of cost developments by the responsible real estate department. The project remains continuously within the planned budget and the additional financial requirements are clearly explained by the review results. Project-related decisions and the dissemination of information are kept transparent in order to ensure public confidence.

    The Canton of Lucerne has outsourced the realisation of this major construction project to a non-profit public limited company, “Immobilien Campus Luzern-Horw AG”. This enables efficient and targeted construction in compliance with the referendum and without affecting the special loans that have already been approved.

    Outlook and significance for the region
    Director of Education Armin Hartmann emphasises the supra-regional significance of the project: “The Horw campus will have a lasting impact on the educational landscape and the business location. Its impact will reach far beyond the borders of Lucerne into the whole of Central Switzerland.” The realisation of this visionary project is therefore expressly welcomed and supported.

    The successful completion of the preliminary project has paved the way for the next phase of the construction project. The project management team will promptly initiate the next steps, with the start of construction scheduled for 2026.

    The new GIS browser as a public service for professionals and private individuals

    The canton of Zurich offers a huge pool of data with a spatial reference (geodata). Most of it is accessible free of charge via the GIS browser. Around 200 digital maps, grouped according to 21 main themes such as buildings, flora and fauna, leisure and geology, can be accessed online. Most of the data can be used without restrictions and the map content can be downloaded and printed directly.

    Broad benefits for professionals and private individuals
    The GIS browser is a useful planning and decision-making tool not only for professionals, but also for private individuals. Location factors such as the age of a house, proximity to public transport stops, shops, schools or sports facilities, planned building sites and journey times on the road network can be easily checked. Up-to-date and precise facts on numerous issues are available.

    History and development of the GIS browser
    Since its launch in 1999, the GIS browser has undergone continuous development. The new version is the third generation. Most of the publicly relevant maps are already available and the migration of the remaining maps is continuing.

    Advantages of the new GIS browser
    The portal has a new design and the user interface is intuitive and self-explanatory, even on smartphones and tablets. An intelligent search function makes it easier to find the desired map. The map views can be customised and used even better thanks to new functions such as filters and favourites lists.

    Integration into the new cantonal geoportal
    The geodata of the Canton of Zurich is also available in the geodata catalogue and geodata shop. These systems are now centrally accessible via the new geoportal geo.zh.ch. The geoportal also offers news on new maps and a help and support area.

  • New mortar plant opens in Liaoning

    New mortar plant opens in Liaoning

    Sika has commissioned a state-of-the-art mortar plant in Liaoning, China. The globally active speciality chemicals company for construction and industry announced in a press release that this is its 34th production site in China. Mortar, tile adhesives and waterproofing solutions are to be produced there and supplied to customers in three provinces in the north-east of the country and in east-central Mongolia. The aim is to shorten delivery times and optimise service.

    According to the press release, the product range includes mortar products that contain up to 20 per cent recycled raw materials during production, such as waste dust and mineral residues. At the same time, the plant opening marks the start of an initiative for Sika to switch from natural to alternative sands. Sika aims to cover half of its sand requirements with alternative materials by 2028.

    The new building houses production facilities, offices, laboratories and infrastructure for warehousing and logistics. “The expansion underlines our commitment to quality and excellence and is also aligned with global sustainability goals,” said Philippe Jost, Regional Head Asia and Pacific.

  • Opening date announced for new building of Baden Cantonal Hospital

    Opening date announced for new building of Baden Cantonal Hospital

    Baden Cantonal Hospital(KSB) has announced the opening date for its new building. According to a press release, the new KSB will officially open on Tuesday, 25 February 2025, with the main move taking place the following weekend. The new building took six and a half years to complete. With a usable area of 76,215 square metres, it will offer around 30 percent more space than the building in which the KSB has been housed since 1978.

    The move will be completed in five days. A total of 4571 cubic metres of medical technology and other goods will be moved, according to the KSB press release. This corresponds to the load of 76 lorries of 40 tonnes each. The project is divided into three phases, according to the press release. In the preliminary move, material will be moved so that the doctors and nurses in the new building can start work immediately. During the main move, the intensive care unit, the monitoring ward, neonatology and the emergency department will take priority. Hospital operations will continue as normal.

    The new building will actually be ready sooner. But the KSB management deliberately chose February as the date for the move. “Theoretically, the new building would be ready for occupation as early as next autumn,” KSB CEO Adrian Schmitter is quoted as saying. However, moving before the autumn holidays would have been tight. This is because the building still has to undergo numerous complex tests beforehand. In addition, all operating licences must be obtained.

    As the KSB is always very busy between October and January and many patients with infectious diseases are treated during the flu epidemics, it was decided to use the time window with fewer patients from the end of February for the move. Details on the new KSB building can be found in KSB magazine 02-2024.

  • Study on home ownership in Switzerland published

    Study on home ownership in Switzerland published

    Houzy, the Zurich-based platform for homeowners, has commissioned and published a recent study. According to a press release, the company wanted to collect data on the current and future behaviour of homeowners in Switzerland. Houzy surveyed 80,000 households online for the representative study. 1906 house and apartment owners answered the questionnaire from January to the end of March 2024. Three quarters of them were house owners and one quarter flat owners.

    The study focussed on the areas of renovation, heating and energy supply. It revealed that 69.4 per cent of all homeowners used tradesman services in the past year. The average order volume was CHF 15,000.

    In addition to renovations, the focus was also on alternative heating systems. 5 per cent of homeowners plan to modernise their heating systems and find alternatives to fossil fuels in 2024. At the same time, 33.5 per cent of households that still use oil and 8.85 per cent of those that use gas want to change their heating systems. One tenth of Swiss homeowners are planning to install solar panels this year in order to produce at least some of the electricity they need themselves.

    Another focus was on intentions to sell residential property. A seventh of the homeowners surveyed expressed such intentions. of these, 20 per cent would still like to sell their home in 2024. Extrapolated, this means that 3.2 per cent of all houses and flats in Switzerland will come onto the market this year, according to the press release.

  • Majority do not want to reduce living space

    Majority do not want to reduce living space

    The study ” Living space utilisation from an individual perspective ” conducted by the Zurich University of Applied Sciences(ZHAW) revealed that 70 percent of those surveyed are not prepared to downsize their living space. Among those living in so-called empty nests, i.e. with empty rooms of fledged children, only 26 per cent feel that their home is too big. An excess of two rooms, i.e. two more rooms than the number of people living in the household, is considered ideal by the respondents, according to a statement from the ZHAW. According to the study, only 42 per cent of respondents willing to move are prepared to reduce the number of rooms. 32 per cent do not want to deviate from their expectations regarding housing costs.

    “It turns out that the combination of moving and downsizing – i.e. two drastic changes at the same time – is particularly challenging,” Selina Lehner, co-head of the study, is quoted as saying. “If there is also a lack of important incentives, this decision is often postponed.” Only one in three people surveyed believe that older couples or single people in flats that are too large should give up their living space for younger families. According to the ZHAW, the fact that the new rent for smaller flats is often more expensive than the existing rent in the larger flat plays a role here.

    The home office is gaining in importance. 61 per cent of those surveyed stated that they wanted to set up a home office in the future. This is because “an external office, for example, is not as attractive as an office within your own four walls,” says study co-leader Holger Hohgardt.

    A total of 1097 people in German-speaking and French-speaking Switzerland took part in the study in spring 2024. The ZHAW conducted the survey in collaboration with the Federal Office for Housing, the Fédération Romande Immobilière, the Swiss Homeowners’ Association and Raiffeisen Switzerland.

  • New fountain enriches recreation area at Lancy-Bachet railway station

    New fountain enriches recreation area at Lancy-Bachet railway station

    The Dietiker construction company Walo Bertschinger has upgraded the recreational zone at one of the two railway stations in the canton of Geneva with a special fountain. According to a Facebook post, green spaces as well as meeting and leisure facilities were created at Lancy-Bachet station as part of the SBB ‘s CEVA infrastructure project.

    To create an atmosphere of relaxation, Walo has installed a unique fountain between the station and the neighbouring green spaces. The material combination of chrome steel, flowing water and the calm BituTerrazzo has a harmonious effect and offers a perfect oasis of relaxation for a lunch break or a sunny afternoon, according to the information from Walo. BituTerrazzo is an innovative surface covering whose appearance can be customised. It is a polished mastic asphalt screed, according to the manufacturer’s product page.

    The municipality of Lancy, with a population of around 35,000, has two railway stations: Lancy-Bachet and Lancy-Pont-Rouge. They are located on the railway line from Geneva to Annemasse in France, which is also known as CEVA (Cornavin-Eaux-Vives-Annemasse). It was put into operation in December 2019. The cross-border railway network between Switzerland and France is also known as the Léman Express.

  • New pipeline cadastre portal creates transparency and added value in the construction industry

    New pipeline cadastre portal creates transparency and added value in the construction industry

    Since 1 May 2024, the canton of Zurich’s new pipeline register has mapped all supply and disposal lines, both above and below ground. The previously time-consuming procurement of plans for existing pipelines has been considerably simplified by the new central portal. This comprehensive source of information is now available to the public free of charge and offers significant added value for planning, construction and maintenance work.

    Easy access to pipeline information
    Until recently, it was time-consuming and complicated to obtain information on pipelines in a specific area or on a plot of land, as this had to be requested individually from the owners or the respective utilities. The canton of Zurich’s new centralised pipeline register now integrates the pipeline information of over five hundred utilities operating in the canton into a single system. These pipelines include water, wastewater, electricity, district heating, gas and communications. The data is regularly updated by the utilities themselves.

    Wide range of benefits for various user groups
    The pipeline cadastre portal offers numerous benefits for various interest groups, including utilities, administrations, construction companies, rescue and security services and private users. Reliable information on the type and location of pipelines is essential for the planning and coordination of construction projects as well as for the maintenance and expansion of pipelines. Transparent documentation considerably reduces the risk of damage. However, it should be noted that the pipeline register may not be used as a basis for excavation work. Detailed information must still be obtained directly from the responsible utility.

    User-friendliness and comprehensive data provision
    The portal is designed to be user-friendly. Users can search for municipalities, plots or roads and select the desired medium. The corresponding pipes are then displayed in the map section. The data can be easily downloaded in the most common formats. In addition, information such as owner details and contact information for the works is provided.

    The pipeline cadastre portal can be accessed at https://leitungskataster.zh.ch. Prior registration is required to use the portal. Further information on the cantonal pipeline cadastre can be found on the website zh.ch/leitungskataster.

    With this new portal, the canton of Zurich is taking a significant step towards more efficient and safer construction and planning processes.

  • New player in the UK recycling market

    New player in the UK recycling market

    Holcim is acquiring the ballast recycling company Land Recovery, based in the British county of Cheshire. With its 85 employees, it uses railway ballast and demolition material for the production of ready-mix concrete, precast elements and asphalt.

    According to a press release, this acquisition expands Holcim’s access to construction waste. Land Recovery processed 300,000 tonnes of this material last year.

    “Land Recovery strengthens Holcim’s leading position in circular construction,” Holcim CEO Miljan Gutovic is quoted as saying. “This brings us closer to our Group target of recycling 10 million tonnes of construction waste in 2024.”

    Land Recovery was founded in 1982 by the Beecroft family. With four sites in the UK, the company’s services include the supply of primary ballast for rail transport, the handling and processing of spent ballast and its recycling into new construction solutions.

    The transaction follows Holcim’s acquisition last year of Sivyer Logistics, a manufacturer of recycled demolition materials for the London construction market.

  • New wooden apartment blocks with innovative TS3 technology

    New wooden apartment blocks with innovative TS3 technology

    It only takes a few minutes’ drive to separate Zurich city centre from Zollikerberg, a part of the village of Zollikon. Having just stood on Sechseläutenplatz in front of the opera house, wide meadows and self-picking fields open up shortly afterwards. Just a stone’s throw away from Forchstrasse, which directly links the town and the countryside, two wooden apartment blocks were completed last year – on the site of a farm that is still inhabited and farmed.

    Harmony between tradition and modernity
    Sheep used to graze regularly on the estate’s large meadow. Today, two four-storey buildings with a total of 22 rental flats tower above the grass. The two apartment blocks form a harmonious ensemble, which could possibly be supplemented by a third building at a later date, should densification be required. At the start of planning, it was not yet clear whether the buildings would be timber or solid construction. The clients had not made any specific specifications when they announced a private competition in 2018. However, chance favoured timber construction: the Zurich-based firm Merkli Degen Architekten, which was invited to take part in the competition and won, was working with Timbatec AG at the time. Together with the University of Applied Sciences Biel and ETH Zurich, the well-known Swiss engineering firm was developing a new connection technology to bridge larger spans with cross-laminated timber panels – without beams or additional intermediate supports.

    The future of construction
    In future, it should therefore be possible to achieve with wood what was previously only possible with reinforced concrete. TS3 connection technology was still in its infancy in 2018, but is now well established. Solid timber panels that can form entire floor slabs open up completely new possibilities for timber construction.
    “It was purely by chance that we became aware of TS3,” explains Ueli Degen, one of the founders of Merkli Degen Architekten. “We were originally talking to the engineers at Timbatec about another timber construction project.”

    They told us about the development of their latest connection system and presented us with an example. This ground-breaking technology has stayed with us ever since. At some point, we came up with the idea of using TS3 for the construction project in Zollikerberg. Before deciding whether to use timber or solid construction, thorough investigations and comparisons were carried out. In the end, the timber design prevailed, which was later realised by the company Holzbau Oberholzer GmbH. By using a timber building, it was possible to create a harmonious connection to the existing farmhouse, which is also made of wood.

    The combination of a timber construction with TS3 technology also promised to be an economically attractive solution that would also significantly shorten the construction time. Nevertheless, it took a while before the clients decided in favour of timber construction. Five years ago, when the buildings were planned, a lot of persuasion was still needed to push through a timber construction of this size.

  • Cross-border commuter boom in Geneva – growth and housing shortage

    Cross-border commuter boom in Geneva – growth and housing shortage

    The canton of Geneva is experiencing a sustained increase in the number of cross-border commuters who live in France and commute to work in Geneva. Between the first quarter of 2021 and the first quarter of 2024, the number of these cross-border commuters rose by 33,000 to a total of 399,000. This development was boosted by the Léman Express and the liberalisation of home office rules in 2023.

    Rising share of cross-border commuters in the labour market
    The number of cross-border commuters from France working in the Lake Geneva region has risen by 26% in the last three years. The share of cross-border commuters in the workforce rose from 13.2 percent in the first quarter of 2021 to 14.9 percent in the first quarter of 2024. This is due to the booming labour market, the housing shortage in Geneva and the more attractive housing costs in neighbouring France.

    Impact of the Léman Express
    The Léman Express, which opened in 2020, has made cross-border commuting much easier by reducing the journey time between Annemasse and Geneva’s main railway station by around 40 per cent. 70,000 commuters now use the Léman Express every day, giving it a market share of 43 per cent. This has led to a construction boom around the new railway stations and increased the attractiveness of cross-border commuting.

    Housing market in Geneva and neighbouring regions
    Geneva has been struggling with an acute housing shortage for years. The vacancy rate was just 0.4 per cent in 2023, while the supply rate of rental flats fell from 5.3 per cent to 4.2 per cent between 2021 and 2023. In comparison, housing costs are significantly lower in France, which encourages many workers to live there. However, this has also caused prices to rise in these areas.

    Future developments and challenges
    The population growth trend in the French part of the Geneva metropolitan area is expected to continue. From 2024 to 2030, annual population growth of 1 per cent is expected in the canton of Geneva, while the neighbouring French arrondissements are likely to exceed this figure. This will continue to pose challenges for infrastructure and the housing market on both sides of the border.

    The Lake Geneva region faces the challenge of reconciling the dynamic labour market and the increasing number of cross-border commuters with the existing housing shortage. Innovative transport solutions such as the Léman Express and the liberalisation of home office regulations play a key role, but also require long-term strategies to tackle the housing market problem and ensure the sustainable development of the entire region.

    Construction company Implenia has won a second sub-project in the Rogfast tunnel project with its Norwegian partner Stangeland Mask in. E02 Kvitsøy is even more complex than the E03 Boknafjord Tunnel, which Implenia is already building together with Stangeland Maskin as a joint venture, and is worth CHF 420 million to Implenia. The order value for the entire project is CHF 540 million

    “We are proud to have been selected for this important project together with our joint venture partner Stangeland Maskin,” said Erwin Scherer, Head of Tunnelling at Implenia, in a press release. “E02 Kvitsøy is another complex tunnel project and therefore fits perfectly with our strategy, and we will contribute our extensive expertise in tunnelling, concrete and water and frost protection.” The contract with the Norwegian Public Roads Administration is scheduled to be signed on 7 June.

    E02 Kvitsøy is an 8.8 kilometre long two-way tunnel with a cross-section of 10.5 metres. It is to be built south and north of Kvitsøy in Fylke Rogaland in southern Norway at a depth of around 230 metres below the sea surface. The tunnel includes two ventilation shafts, a junction with ramps and a roundabout as well as 1.6 kilometres of road in the daytime area, two bridges and a large sea embankment. An industrial estate is to be built on this. Work is scheduled to start in late summer 2024 and be completed in 2030, with Implenia holding a 77 per cent stake and Stangeland Maskin 23 per cent in the joint venture. Implenia is responsible for tunnelling and lining the tunnel in the upcoming construction project, while Stangeland Maskin is responsible for material transport, including backfilling, earthworks and road construction in the tunnel and surface areas.

  • Inauguration of a photovoltaic system at Limeco

    Inauguration of a photovoltaic system at Limeco

    According to a press release, the Limmattaler Regiowerk Limeco, based in Dietikon, has inaugurated a photovoltaic system on the roof of the wastewater treatment plant(ARA). According to the company, 624 solar panels with a capacity of 265.2 kilowatts peak generate as much solar power as 70 households with an annual consumption of 3,600 kilowatt hours.

    On an area of 1220 square metres, 252,000 kilowatt hours of green electricity are to be produced, primarily for the ARA’s own requirements and the waste recycling plant. Any surplus energy will be fed into the public grid and made available to the general public.

    The aim is to promote the expansion of renewable energy supply. Limeco plans to convert the supply of the entire Limmat Valley to CO2-neutral energy sources by 2050.

  • First use of CPC concrete slabs in building construction

    First use of CPC concrete slabs in building construction

    The Zurich University of Applied Sciences(ZHAW) is using the CPC concrete slabs (Carbon Prestressed Concrete) it has developed for the first time in building construction. This refers to concrete slabs that are reinforced with prestressed carbon. According to a press release, an innovation laboratory has been created in Winterthur from these innovative components, which functions as an information and event centre for sustainable construction. The carbon concrete panels are not only recyclable, they also have a significantly lower impact on the environment than conventional reinforced concrete during production. “Thanks to the new lightweight construction method in concrete, we reduce the CO2 footprint by a factor of two to four and save up to 75 per cent material compared to conventional construction methods,” Josef Kurath, co-founder of CPC AG, a spin-off of the ZHAW, and developer of the carbon concrete panels, is quoted as saying in the press release.

    The carbon concrete panels used for this purpose are currently being manufactured, processed, cut to the millimetre and assembled into building elements at Holcim ‘s first CPC plant in Germany. This preliminary work saves time during assembly on site, as there is no need for time-consuming on-site reinforcement work. “This results in much shorter construction times, which is a particular advantage for urban construction sites,” continues Kurath. Extensions or changes to buildings are also possible at any time. “Our carbon concrete construction system works in a similar way to Lego, but like a modern version of it, with customised components.” And CPC even has advantages over conventional building materials in the event of dismantling: 90 per cent of the processed material can be reused.

  • Career prospects in Swiss timber construction

    Career prospects in Swiss timber construction

    The importance of the timber construction industry
    The timber construction industry plays a key role in Switzerland, particularly in the area of sustainable construction and energy-efficient building refurbishment. Building with wood is an environmentally friendly and climate-neutral method that ensures minimal energy consumption both during the construction phase (grey energy) and during the subsequent operation of the building. The timber construction industry makes a significant contribution to shaping Switzerland’s future.

    Career prospects and further training options
    Once they have completed their basic training, trained carpenters have numerous options open to them: They can work as highly qualified specialists in the company, gain experience on the mill or abroad or continue their education to become a foreman, foreman, technician or engineer, all the way up to master craftsman. If the vocational baccalaureate has not already been completed during the basic training programme, it can be completed as a full-time course of study within a year of completing the basic training programme. This enables a seamless transition to a higher technical college or university of applied sciences without examinations. The career plan for timber construction in Switzerland offers the opportunity for lifelong learning, individual further training and specialisation as well as various advanced training courses. Training as an energy consultant, project manager for solar systems or craftsman in monument preservation are just a few examples. A career in timber construction thus offers the opportunity to develop and orientate yourself individually according to your own wishes and needs.

    Carpenter EFZ
    Carpenters at EFZ level mainly work with wood and are proficient in timber construction activities. They work as generalists in operations as well as in shell construction and finishing.

  • Women in timber construction

    Women in timber construction

    Approaches and challenges
    Professor Katrin Künzi Hummel from Bern University of Applied Sciences (BFH) has been working with women in timber construction for a long time. Based on her practical experience and scientific studies, she presented various approaches in her lecture on how timber construction companies can drive change. She emphasised that timber construction professions should not just be limited to technical production, as they also have a design aspect. This should be emphasised more in order to appeal to women. The industry and companies should rethink their communication, as content, language and images often reflect male stereotypes. In order to attract women to the timber construction profession, role models such as “Carpenter on Tour” are important to show what is possible. If women work in timber construction companies, their examples can serve as career models. In addition to the desire for a future-proof career, the compatibility of work and family also plays an important role for many women. Companies should therefore consider options such as more flexible working hours, part-time work or shift work, not just to attract female specialists.

    Challenges for female carpenters
    It became clear during the panel discussion at the industry event that female carpenters still have difficulties entering the industry. Camille Seidler, now a timber construction engineer at Pirmin Jung AG, criticised the lack of support during her apprenticeship as a carpenter. Lara Zwiefelhofer, known as “Carpenter on Tour” for Holzbau Schweiz, had better experiences with her employers, but emphasised that women had to work harder to be accepted. Astrid Späti’s example showed that initiative is required. She joined the operations of Späti Holzbau AG and created her own areas of responsibility. Späti pointed out that although women have access to the industry, they mainly work in the administrative area. She emphasised the importance of the network between female carpenters and female managers for the exchange of knowledge. Jürg Hugener, head of the timber construction department at Wetzikon Vocational College, was pleased about the increase in female apprentices in his field, but emphasised the need for support from teaching staff and companies in order to make training positive for women.
    Timber construction, a craft steeped in tradition, is slowly but surely changing. Long dominated by men, the various professions in timber construction are increasingly opening up to the diverse talents and skills of women. However, statistics show that there is still a long way to go to achieve a better balance between men and women in skilled trades such as carpentry. In the last three years, only 1 to 2 per cent of women completed an apprenticeship as a carpenter.

    Encouragement for women in the carpentry profession
    At the end of the discussion, advice for aspiring female carpenters and suggestions for companies were discussed. Lara Zwiefelhofer and Camille Seidler encouraged women to simply get started. Women should have the confidence that they have the same manual skills as men. However, it also requires perseverance and the courage to openly communicate your own needs. An appreciative team culture and promotion of communication as well as investment in modern technical aids were called for from the companies. At the end of the discussion, Astrid Späti emphasised the importance of a better network for women in timber construction. Jürg Hugener supported this and called on companies to actively support female career starters.

  • Mortgage reference interest rate stable at 1.75 per cent

    Mortgage reference interest rate stable at 1.75 per cent

    The mortgage reference interest rate, which is decisive for setting rents throughout Switzerland, will remain at 1.75 per cent. This was announced on 3 June 2024 and is based on the volume-weighted average interest rate for domestic mortgage receivables, which stood at 1.72% on 31 March 2024. This average interest rate has not changed since the last quarter, meaning that the reference interest rate relevant under tenancy law remains at 1.75 per cent, rounded to the nearest thousandth of a percentage point. This stability will be maintained until there is a significant change in the average interest rate of below 1.63 per cent or above 1.87 per cent.

    Significance for rent claims
    The reference interest rate of 1.75 percent has remained unchanged since 2 December 2023. Tenancy agreements based on a higher reference interest rate of 2.00 per cent or more are still entitled to a rent reduction. Conversely, landlords are entitled to a rent increase if the underlying reference interest rate is 1.50 per cent or lower, in accordance with the provisions of tenancy law, which stipulate an increase of 3 per cent per quarter of a percentage point.

    Exceptions and additional influencing factors
    There are exceptions for certain rental agreements such as indexed or graduated rents and turnover rents for commercial premises. Subsidised flats are also often subject to special regulations. In addition, other cost factors such as the change in the national consumer price index and maintenance and operating costs can influence the rent structure. Inflation can account for 40 per cent of the rent calculation, which can lead to adjustments.

    Regular publication and legal basis
    The mortgage reference interest rate and the underlying average interest rate are published quarterly by the Federal Office for Housing (BWO), with the next publication on 2 September 2024. Since 10 September 2008, the uniform reference interest rate has served as the basis for setting rents in Switzerland, in accordance with Article 12a of the Ordinance on the Rent and Lease of Residential and Commercial Premises (VMWG). This regulation replaced the interest rates for variable mortgages previously applicable in the individual cantons and ensures a standardised and transparent rent calculation throughout the country.

  • Sustainable construction with reusable carbon concrete panels

    Sustainable construction with reusable carbon concrete panels

    The introduction of carbon fibre-reinforced concrete slabs by the ZHAW marks a significant advance in building construction. These panels, which are prefabricated and cut to size in the factory, can be quickly assembled on site. “Our carbon concrete construction system works in a similar way to Lego, but like a modern version of it, with customised components,” explains ZHAW researcher Josef Kurath. This system not only significantly shortens construction times, but also enables flexible adaptations and extensions to buildings.

    Sustainability and reuse
    A prime example of the application of this technology is the 120 square metre pavilion in Winterthur, which serves as an innovation laboratory for sustainable construction. Thanks to a new sharing model, around 90 per cent of the material used can be reused, which represents significant progress compared to conventional methods, where only around 10 per cent can be reused. In view of the fact that cement is responsible for eight per cent of global greenhouse gas emissions, this development represents an important contribution to reducing the ecological footprint.

    Carbon fibres at the heart of
    The CPC (Carbon Prestressed Concrete) concrete slabs are characterised by their durability and environmental friendliness. “Thanks to the new lightweight construction method in concrete, we reduce the CO2 footprint by a factor of two to four and save up to 75 per cent material compared to conventional construction methods,” explains Kurath. The combination of pre-stressed carbon fibres and concrete offers outstanding structural properties: carbon absorbs tensile forces, while concrete absorbs compressive and shear forces. As a result, no cracks occur under load and the panels retain their shape and load-bearing capacity despite their reduced thickness.

    Industrial production and future prospects
    The CPC slabs are manufactured by Holcim in the first plant in Germany, while the carbon fibres are produced in Switzerland, in future using bio-based carbon. “The developed panels will also be produced in this country in the future and the new construction system will be widely used in building construction – the Swiss market in particular is predestined for this,” says Kurath. Further research will focus on optimising the panels for sound insulation and fire protection as well as on earthquake-proof constructions. Innovative joining techniques enable almost endless horizontal planes without additional connecting elements, which further increases the flexibility and efficiency of construction.

  • Professionalisation of the management of residential and commercial properties

    Professionalisation of the management of residential and commercial properties

    Wincasa wants to break new ground in property management. The property service provider, which is part of Implenia, is splitting its corresponding services into the residential and commercial divisions, Wincasa announced in a press release. Employees will be trained in newly created functions and job profiles.

    The new Target Operating Model (TOM) is intended to professionalise the two areas and enable even more needs-oriented and use-oriented management of different properties. “The aim of the TOM project is to implement an operating model that covers today’s management requirements,” says Philipp Schoch, Head of Property Management at Wincasa, in the press release.

    As part of the project, Wincasa will set up 18 physical locations throughout Switzerland by the end of 2025 for the management of residential tenants and eight locations for the management of commercial tenants. The so-called walk-in locations in the residential sector can be used, for example, to clarify questions about the tenancy agreement or to report damage. In the commercial sector, on the other hand, “it’s about more complex properties, long-term tenancy agreements and vacancies that are more significant,” explains Schoch. Here, Wincasa wants to deploy qualified specialists “who provide highly professional support to commercial tenants in all phases of the management process”. Real-time monitoring of important key figures such as vacancy rates at the locations should show property owners the measurable success of the new management model.
