  • Strabag relies on 3D models in the Fahrweid

    Strabag relies on 3D models in the Fahrweid

    Geroldswil , Weiningen and Limeco are part of the owner of the joint project drainage Fahrweid. As part of the project, a new sewer system is being implemented. For the central shaft structure, the construction company Strabag relies on Building Information Modeling (BIM), as stated in a message . A software is used for the planning, through which, among other things, 3D models of the buildings to be realized are created.

    "We are carrying out the central manhole structure together with the planners from ILF Switzerland using OpenBIM2Field as a pilot project," is how Stijepan Ljubicic, BIM manager at Strabag, is quoted in the message. The 3D models in particular have proven to be helpful. “The visual representation is a big advantage. Plans in 3D are easier to understand than complicated paper plans, especially for people in the team who speak other languages – they understand the 3D model better and faster, ”says foreman Adrian Wildhaber. But changes are also easier to implement than with plans on paper, says site manager Sven Landis, "in the model they are easily generated at the push of a button".

  • Eberhard wins the business environment award

    Eberhard wins the business environment award

    The business environment prize is awarded annually and is intended to honor companies for success and sustainable action. The winner of the 2020 award is Eberhard Bau AG, based in Kloten. The company has found a solution to reuse and recycle the large amounts of construction waste that are constantly generated. Under the heading of “ urban mining ” – the city as a source of raw materials – the family company has been one of the pioneers in the reuse of building materials that have already been used for a decade and a half. Today, according to a press release , up to 450,000 tons of mineral rubble are processed annually in its recycling center, which is available for new buildings.

    In the opinion of Patrick Eberhard, Head of Sales Building Materials, there is often a lack of awareness in the construction industry that construction waste is the largest waste stream in Switzerland. The Eberhard company recycles demolished houses to create completely new buildings from these raw materials. For example, 99 percent of the new Europaallee in Zurich was built with second-hand quality building materials.

    "Switzerland needs the environmental award for business, because changes begin with lighthouses that can be used for orientation," the press release quotes the jury president and former Federal Councilor Doris Leuthard.

  • Pandemie verzögert Erholung im Schweizer Hochbau

    Pandemie verzögert Erholung im Schweizer Hochbau

    Die Bautätigkeit im Hochbau werde in diesem Jahr um 3,1 Prozent geringer als im Vorjahr ausfallen, prognostiziert BAK Economics in einer Mitteilung zur aktuellen Bauprognose des Wirtschaftsforschungsinstituts. Im kommenden Jahr wird ein weiterer Rückgang um 1,8 Prozent erwartet. Als Begründung weist BAK Economics auf im Jahresvergleich gesunkene Zahlen bei im Bau befindlichen Projekten, Baubewilligungen und Baugesuchen hin. „Diese Indikatoren sprechen dafür, dass sich die Hochbautätigkeit in einem zyklischen Abschwung befindet“, erläutern die Analysten.

    Sie gehen von einem Abschwung in allen Sparten des Hochbaus aus. Dem Wohnbau käme dabei allerdings aufgrund des besonders hohen Anteils eine besondere Rolle zu, heisst es weiter in der Mitteilung. Hier hätten steigende Leerstände zu einem Rückgang der Baubewilligungen seit 2018 geführt.

    Der Betriebsbau werde hingegen vor allem von den Auswirkungen der Pandemie gebremst, da in dieser Sparte Bauprojekte von besonders betroffenen Branchen wie dem Tourismus erfasst werden, erläutern die Analysten. Den Abwärtstrend beim Infrastrukturbau führen sie hingegen eher auf zyklische Effekte zurück.

    Mittelfristig gehen die Analysten von einer wieder steigenden Hochbautätigkeit in allen Sparten und Landesregionen aus. Dem Wohnbau werden dabei schwächere Wachstumsraten als in der Vergangenheit prognostiziert. Gute Perspektiven sehen die Analysten aufgrund gewachsener Bedeutung von Transport- und Logistik für den Lager- und Hallenbau. Regional weisen sie der Region Zürich/Aargau sowie dem Genferseeraum die höchsten Wachstumsperspektiven zu.

  • The canton of Zurich and SBB are planning bike and bus projects together

    The canton of Zurich and SBB are planning bike and bus projects together

    The Canton of Zurich wants to work more closely with SBB on upcoming projects. According to a cantonal press release , both partners want to use synergies and save costs. For the canton of Zurich it has been shown that it makes sense to integrate the three cantonal projects to expand the bike and bus network into the major Brüttenertunnel project and to work on these projects together with the SBB.

    "The Brüttenertunnel project offers the opportunity to hand in hand the most extensive bike project to date in the Canton of Zurich and to expand public transport in the Glattal region," said Economics Director Carmen Walker Späh as quoted in the press release. According to the overall traffic concept of the Canton of Zurich, the share of bicycle traffic in the total traffic volume is to be increased continuously to 8 percent by 2030.

    The government council has therefore applied for a property loan of CHF 73.1 million from the cantonal council. The aim is to realize the pilot project of a fast bike route from Zurich-Oerlikon via Wallisellen and Dübendorf to the Zurich Oberland "barrier-free, coherent, safe and comfortable".

    A main bicycle connection from the Im Lampitzäckern quarter in Dietlikon along the SBB route in the direction of Baltenswil, a main bicycle connection, is intended as a feeder to this rapid cycle route. It is also part of this synergy project. With the redesign of Bahnhofstrasse, the cycle route in Dietlikon and Wangen-Brüttisellen is to be continuously expanded to become the main connection and the network gap in the direction of Baltenswil is to be closed.

    Finally, in the course of the construction work on the Brüttener Tunnel, the Baltensilerstrasse underpass in Bassersdorf will be removed. In addition, the canton is planning a bus lane in order to be able to prefer the bus service from Baltenswil to Bassersdorf train station.

    The planning approval process for the Brüttener Tunnel and the three accompanying projects will run from 2023 to 2025. The accompanying projects will be handed over to the public in stages before the tunnel is due to go into operation at the end of 2034 at the earliest.

  • The Swiss construction industry needs to rethink

    The Swiss construction industry needs to rethink

    The almost complete study on the situation and future of the Swiss construction industry by PwC Switzerland was revised and updated in March in view of the Covid-19 pandemic and its economic effects. There was a clear change in future expectations. The assessments “since Covid-19” were derived from the additional feedback and these were compared with the original assessment “before Covid-19”, according to a press release from PwC Switzerland on the study . Only 58 percent of the 130 companies participating in the study are now positive (92 percent before Covid).

    PwC Switzerland names its study “Make change, take with you what has been tried and tested”. Among other things, it says: “Only those who differentiate win. Creativity and a pioneering spirit are required. The construction industry is facing a paradigm shift towards more differentiation through networked collaboration. Digitization in particular offers interesting opportunities for this. It reduces interfaces, increases the quality of the planning and management processes and promotes the reduction of error costs and idle times in construction. "Covid-19 is likely to drive the" demolition of silo structures in the construction industry and the upcoming reorganization of rigid thought patterns. "

    "Even before the crisis, it became clear that a paradigm shift was required in order to survive in construction – even though the Swiss construction industry will continue to play a major role in many areas of life in the future," said Roland Schegg, Director and Head of Consulting at Family businesses & SMEs at PwC Switzerland.

    87 percent of companies see an opportunity in digitization, but only 62 percent give it a high priority. The use of digital technologies began years ago, according to PwC. But he is mostly limited to administration, marketing, communication or drawing the plans. It is necessary to digitize construction and operation as well. In particular, the planning and execution processes, which are often separated today, could be intelligently linked.

    The construction industry in Switzerland contributes around 15 percent to the gross domestic product. Around 330,000 full-time positions are located in civil engineering. That corresponds to a third of all employees in the industrial sector.

  • Bringhen Group participates in Habitects

    Bringhen Group participates in Habitects

    Habitects launched in 2019 as a digital trading and service platform for the sanitary sector in Switzerland. The Winterthur start-up is now entering into a partnership with the Bringhen Group . The company, which was founded in 1959 and is based in Visp VS, is one of the largest specialist dealers in the construction sector with 14 locations throughout Switzerland and over 120,000 products. "For me this partnership is another important milestone in our company history", Jean-Pierre Bringhen, owner and CEO of the Bringhen Group, is quoted in the announcement from Habitects. "In order to take such a step outside of the traditional market structure, the group of companies had to reach a critical size with a corresponding market coverage."

    Bringhen also financially participates in the Winterthur company. Michael Lochmatter-Bringhen joins Habitects' board of directors.

    Thanks to the partnership, Habitects aims to become a leading marketplace in the Swiss construction trade. To this end, new services for craftsmen are to be launched. Digitization should be used for easier and more efficient handling of construction projects, Christoph Meili, Chairman of the Board of Directors of Habitects, is quoted in the announcement. This should benefit all stakeholders, from homeowners to architects and general contractors.

    Habitects is part of the ConReal Swiss digital ecosystem. This has spawned other companies in the construction and real estate sectors, including Fixify , houzy and SmartDevis . Further start-ups are in preparation, according to the announcement.

  • Holcim supplies sustainable concrete for HSG Learning Center

    Holcim supplies sustainable concrete for HSG Learning Center

    The HSG Foundation is currently building the new HSG Learning Center on the premises of the University of St.Gallen ( HSG ). The general contractor HRS Real Estate AG has commissioned the Swiss Holcim AG with the delivery of the concretes. A new, more sustainable Holcim product, EvopactPLUS, is used in around half of the total of 6,000 cubic meters of concrete used.

    "With EvopactPLUS we close the building material cycle, conserve natural resources and save CO2," said Roger Dällenbach, Regional Manager for German-speaking Switzerland and Ticino, in a press release from Holcim. The new type of concrete replaces natural gravel with a reclaimed aggregate from the region. It also includes Susteno, which, according to the company, is the "first and only resource-saving cement in Europe that uses mixed granulate from demolitions as an additive". This fine material is not used in conventional concrete production and must therefore be dumped.

    "Compared to an already optimized mass cement, the use of Susteno saves 10 percent CO2," the press release said. Regionality also plays a role: the building material is delivered from the Holcim concrete plant in St.Gallen, just three kilometers from the construction site. "It was an experiment for us because we were working with the product for the first time," Holcim foreman Marcel Kunz is quoted as saying. He is very satisfied with it, "it's a wonderful concrete."

    In the future, the modern building should focus less on technical learning than on learning the necessary skills such as critical thinking and self-reflection, according to the client, the HSG Foundation . It finances this project largely from donations from HSG alumni .

  • Intershop starts building an assembly hall for Stadler

    Intershop starts building an assembly hall for Stadler

    Intershop creates a new assembly hall for Stadler Winterthur . According to a press release , the building permit is now available. The investment volume amounts to around 16 million francs. The start of construction is planned for the current week, the completion of construction for the end of 2021. As Stadler announced after the agreement with Intershop Holding was concluded, the Zugbauer will lease the plant from the Intershop subsidiary SGI City Immobilien AG on a long-term basis. The lease has a minimum term of 15 years, according to Intershop.

    With the new building, Stadler Winterthur is expanding its competence center for bogies. On around 13,250 square meters of land, additional storage and assembly areas are being built for the construction of bogies for standard and broad gauge trains as well as for trams. The commissioning of the new hall is planned for 2022. In February, Stadler announced its intention to create up to 50 new jobs with the expansion of the production facility at the Winterthur location.

  • Implenia wins building construction projects in Germany

    Implenia wins building construction projects in Germany

    The construction service provider Implenia has received new building construction contracts in Germany. According to a press release , the order is worth around 108 million francs.

    Implenia will construct three buildings with an area of around 25,000 square meters for Landmarken AG in an industrial park in Bochum-Laer. Construction is scheduled to start this fall.

    As a European pilot project, the new construction of an innovative sports and leisure facility on an industrial wasteland in the Ruhr area "which is being built for the first time in continental Europe" is intended. The 60 systems of this type that already exist worldwide serve as a model. They should offer a mixture of entertainment, sport, music, gastronomy and events. Further systems are to follow, it says in the message. Construction will start in October and handover is planned for February 2022.

    Prior exclusive partnership phases were decisive for the commissioning of both projects. Implenia worked with the customers and their planning teams to develop economic and technical suggestions for optimizing the project. "The result is cost and deadline security for the client as well as for Implenia."

    In addition to these two projects in the Ruhr area, Implenia will build a residential complex in Mannheim-Waldhof and the expanded shell “for a well-known hotel chain” in Munich near the train station.

  • Reconstruction displaces new construction

    Reconstruction displaces new construction

    Overall, the construction industry barely moved in 2019. According to the provisional figures from the Federal Statistical Office ( BFS ), an increase in construction investments in civil engineering of 3.9 percent offset a decline in building construction of 0.9 percent.

    There was a change from new buildings to renovations and expansions. Investments in new civil engineering buildings fell by 6.9 percent, while investments in conversions and expansions rose by 13.2 percent. In building construction, too, investments in renovations and extensions rose by 1.6 percent, while investments in new buildings fell by 2.0 percent.

    This switch to renovations was particularly pronounced among public clients: Last year they invested 8.8 percent more in renovations and extensions and 7.2 percent less in new buildings. Private clients invested 2.2 percent more in conversions and expansions than in 2018, but 1.4 percent less in new buildings.

  • Porta Samedan is built with recycled building material

    Porta Samedan is built with recycled building material

    The new Porta Samedan shopping center is being realized by Migros Ostschweiz and Pfister Immobilien AG . During these days, the concreting of the floors of the new building is taking place, according to a media release . When it comes to building materials, the partners rely on the circular economy. Recycled products are used for both concrete and cement.

    The one main component in concrete is cement. This comes by train from the Holcim plant in Untervaz GR to the Upper Engadin, where Montebello produces the recycled concrete on site. The Holcim product Susteno is used. According to the information, this is the only resource-saving cement in Europe in which the fine proportion of mixed granulate from demolished buildings is used as an additive, which cannot be used in concrete production. Holcim can completely close the building material cycle with Susteno, as this material would otherwise have to be dumped.

    The other main component in concrete are the aggregates. "Here we rely on recycling: instead of natural gravel, we use demolition material from the region," explains Flurin Wieser from the Engadin construction company Montebello.

    "The Porta Samedan development shows that the building materials industry, with innovative products and solutions, is playing an increasingly important role in the transition to the circular economy and is making a significant contribution to a sustainably built future," said Philippe Rey, Head of Cement Sales German-speaking Switzerland at Holcim Switzerland.

    Porta Samedan is scheduled for completion in 2021. Among other things, it will house the first Migros supermarket in the Engadine.

  • Griesser is the darling of architects

    Griesser is the darling of architects

    Griesser AG received the Architect's Darling award in the sun and weather protection category. As can be seen from a press release by the company from the St.GallenbodenseeArea, it has won the golden phoenix for the second time. In 2018, too, she was victorious in the first prize awarded at the time.

    "The award is confirmation that we are convincing on the market with our products and services," said Urs Neuhauser, CEO of Griesser AG, in the announcement. "We owe the excellent assessment of the architects and planners primarily to our customers, whose projects we have grown to, and to our around 1,300 employees who work daily for the quality of our products and our innovative strength."

    More than 400 architects and planners from Switzerland were interviewed for the award of the Architect's Darling Prize. For the determination of the winners in several categories, the aspects of product selection, price-performance ratio, product quality, innovation and optics or design were decisive, as Griesser informs. The Swiss construction documentation is an information platform for construction products, architecture projects and expert profiles.

  • New building for ASTRA and BFE is ready for occupancy

    New building for ASTRA and BFE is ready for occupancy

    Around 600 employees from ASTRA and BFE will be able to move into the new seven-story building in Ittigen this month. The federal administrative center on the DETEC campus has housed various offices of the Federal Department of Environment, Transport, Energy and Communication (DETEC) since 2006. The new building takes into account the space requirements that have increased since then and brings together previously scattered departments.

    According to a press release , the wood-concrete hybrid construction by the Zurich architects Berrel Berrel Kräutler , which is certified according to the Swiss Sustainable Building Standards (SNBS), relies on the potential available on site. For example, the waste heat from a nearby data center is used to heat the building, and spring water is used for cooling. The project, originally named “Fitzcarraldo” by the architects, uses 100 percent renewable energies and does not cause any CO2 emissions.

    In this modern administration building on the DETEC campus, we can bring together departments that were previously located in two locations in Bern, ”says ASTRA Director Jürg Röthlisberger. "That will simplify the collaboration, improve the team spirit and it can accelerate processes."

    The municipality of Ittigen wants to do everything possible in the future so that the federal government feels at home there, emphasizes municipality president Marco Rupp. In Ittigen they are proud to be able to host most of the DETEC offices.

  • Implenia is taking part in the construction of the Dreiklang Hospital at Aarau Cantonal Hospital

    Implenia is taking part in the construction of the Dreiklang Hospital at Aarau Cantonal Hospital

    "The working group (ARGE) for the new Dreiklang hospital building for Aarau Cantonal Hospital ( KSA ) at the level of general contractor now consists of BAM Swiss AG / BAM Deutschland AG and Implenia," Implenia informed in a corresponding message . The two partners want to implement the project technically and commercially in equal parts. The consortium commissioned the construction company Marti AG with the master builder work.

    Originally, the Swiss subsidiary BAM Swiss AG of the Dutch Royal BAM Group, together with Marti, acted as a consortium for the new Dreiklang KSA building. The KSA has given its approval to the new composition of the ARGE, Implenia explains in the announcement. According to her, the project is “still on track in terms of time and money”. The planning application should be submitted in a few weeks.

    The construction cost of the project remains unchanged at around 560 million francs including VAT, the announcement said. This amount does not include the costs for medical technology. A corresponding contract for work was concluded with the ARGE in January and remains valid even with its new composition.
