  • First tower crane with its own power generation in operation in Baden

    First tower crane with its own power generation in operation in Baden

    The Baden Cantonal Hospital(KSB) is working with the Greenpower crane from Obwalden-based company rollende Werkstatt Kran AG for the renovation of its decommissioned ward block. According to a press release, it is the first tower crane in the world that can generate its own electricity.

    Depending on the operating situation, the crane can reduce electricity consumption by up to 50 per cent. It can also be operated with a smaller mains connection, which means lower installation costs and allows the crane to be used in locations with limited power capacity.

    This is made possible by the design with an integrated energy recovery system and battery storage. “When lowering loads or braking the crane functions, electrical energy is generated, stored and reused for subsequent work steps,” it says.

    With Greenpower, the manufacturer is focussing on the sustainable further development of crane use. “The system is a response to increasing requirements in terms of energy efficiency and grid availability on construction sites,” says Hansheini Dillier, Managing Director of rollende Werkstatt Kran AG.

    According to the press release, the device is used to remove building materials. They contain asbestos, PCBs, PAHs and heavy metals and date back to the construction period in the 1970s. At that time, materials were used for work on tiles and floor coverings, among other things, that are now considered harmful to health or the environment, according to KSB. Strict precautionary measures therefore apply to construction sites on old buildings in accordance with the Swiss Accident Insurance Fund and the Federal Office of Public Health.

    Dismantling of the building can only begin once the pollutants and contaminated sites have been properly disposed of. According to KSB CEO Pascal Cotrotzo, the demolition application is not yet legally binding. The remediation work is running independently of this and should be completed in spring 2026. Until then, the company is hoping for the “green light” from the relevant authorities.

  • Demolition of the Hasler site in Dietikon

    Demolition of the Hasler site in Dietikon

    Limeco is having the Hasler site in Dietikon dismantled. Between October 2024 and April 2025, the glasshouses and halls of the former Hasler plant nursery are to be demolished and the contaminated soil removed, the Limmattaler Regiowerk announced in a press release. Limeco acquired the site last year as a land reserve for the Limmattal Energy Center generation project.

    The Regiowerk is obliged to rebuild its waste recycling plant and expand the wastewater treatment plant (WWTP) by 2034. The Limmattal Energy Center is to be created in the process. The necessary work is to be carried out in stages and make the greatest possible contribution to the energy and climate transition in the Limmat Valley.

    Limeco already acquired the Coop site in Dietikon in 2018 for the implementation of the generation project. The Hasler site will serve as an assembly and installation site during the construction phase. Otherwise, Limeco intends to offer it to third parties for rent or use it for a land swap for more suitable areas.

  • Dismantling for the Lymhof is complete

    Dismantling for the Lymhof is complete

    According to an article in the Lymhof newsletter, the demolition of the Vitis Sport Centre with tennis hall in the Rietpark district of Schlieren has been completed. The construction of the Lymhof can now begin after planning permission and preliminary work have been granted. The vertical farm planned by start-up Yasai in the hall building will not be realised. Yasai recently withdrew from the project because it is realigning itself as a company. The landowner Geistlich Immobilia is now planning to divide the hall into six sections. The rooms, which are up to 9 metres high, could provide space for creative uses such as an artists’ collective, a mixed studio community, cultural uses or neighbourhood offers.

    In February 2024, Schlieren City Council granted planning permission for the Lymhof. The appeal period has now also expired, meaning that the realisation of the new neighbourhood near Schlieren station can begin, according to the press release. The next step is to finalise all official and cantonal requirements. Construction approval for the excavation is expected in summer 2024. The actual construction of the buildings will begin around autumn 2024 and will take around three years.

    The Lymhof should then be ready for occupancy in 2027. In addition to a colourful mix of flats for a colourful mix of residents with different generations and lifestyles, ground floor uses along Wiesenstrasse and a restaurant with catering facilities and hotel rooms will also be built there. Although the 350 or so rental flats will not be ready for occupation until 2027, interested tenants can already register their interest online.

  • New double kindergartens made from re-use components

    New double kindergartens made from re-use components

    This semester, the architecture students of the 6th semester part-time are dealing with the question of how new double kindergartens can be created for the city of Basel from the building component catalogue of the Roche South Basel deconstruction project.

    An ambitious and experimental task and a pilot project
    After visiting the South Area on the Roche Campus in Basel, the students analyse the buildings that will soon be deconstructed for their resource potential for a future as double kindergartens. This is a pilot project, as there is currently no established industry for re-use parts. “New buildings” constructed from re-use resources are a step towards a circular economy in the construction industry. The 10-R cascade and Crade-to-Cradle are brought to the fore as theoretical foundations.

    For this ambitious and experimental task, the Department of Architecture, Wood and Construction at the Bern University of Applied Sciences is working with experts from the companies Gruner, CSD Ingenieure and Erne Holzbau. Every week, different speakers with knowledge and experience in the field give input and take part in the table discussions with the students.

    In partnership with the city of Basel and the Roche company, the students will develop proposals for the further use of the building components by the end of the semester. In the process, living spaces for children will be created by rejoining the building components.

    Re-use for Kidsdesign studio
    The “Re-Use for Kids” design studio is about finding ways to design and build new kindergartens from a catalogue of components from a deconstruction project. The aim is to find principles and parameters that enable a stringent architectural design when reusing building components. The effects of the reused parts on the structure, construction, spatial arrangement and atmosphere of the architecture are examined.

    Addressing the topic requires the inclusion of a wide variety of issues in the design process and is therefore an interdisciplinary task. Various external experts contribute their expertise in the design studio, thus creating a realistic teaching situation.

  • CKW lays high-voltage lines in the ground in Littau

    CKW lays high-voltage lines in the ground in Littau

    CKW investiert in der Agglomeration Luzern in mehreren Projekten in die Versorgungssicherheit und in ein weiterhin zuverlässiges Stromnetz. So erfolgte am 19. September 2022 der Baustart zur Verlegung der Freileitung zwischen der Unterstation Ruopigen und Oberwil in Littau. Die Hochspannungsleitung führt aktuell mitten durch Quartiere und über das Schulareal Rönnimoos. CKW verlegt die Leitung auf einer Länge von 1210 Metern in den Boden. Dank der Verlegung der Hochspannungsleitung wird das Gebiet Rönnimoos entlastet. Zudem ermöglicht sie der Stadt Luzern, das Gebiet Längweiher/Udelboden mit einer neuen Überbauung zu erschliessen und das Schulhaus Rönnimoos zu erweitern. Bis Sommer 2023 soll die aufwändige Verkabelung fertig sein. Danach erfolgt der Rückbau der bestehenden Freileitung.

    Aus wirtschaftlicher Sicht wäre für CKW der Zeitpunkt für einen Ersatz der Hochspannungs-Freileitung noch nicht notwendig. Sie erreicht erst in gut 20 Jahren ihr Lebensende. CKW und die Stadt Luzern haben sich darum bereits 2019 in einer Vereinbarung auf einen Kostenteiler geeinigt. Die Stadt Luzern beteiligt sich mit 995’000 Franken an den Gesamtkosten von 3,2 Mio. Franken. Dadurch entstehen den Netzkunden von CKW keine zusätzlichen Kosten.

    Während den Bauarbeiten wird die Luzernstrasse in Littau im Bereich des Schulhauses Rönnimoos zeitweise nur einspurig befahrbar sein. Die Stromversorgung ist gewährleistet.

    Erneuerung der Unterstation Horw ist bald abgeschlossen
    Bevor die neue Leitung in Littau ans Netz gehen kann, muss die Erneuerung der Unterstation in Horw abgeschlossen sein. Sie ist ein wichtiger Knotenpunkt im CKWVerteilnetz und wird unter anderem von der Unterstation Ruopigen gespiesen. Aktuell erneuert CKW das Gebäude und einen Grossteil der Technik der Unterstation Horw.
    Zudem erfolgt an den bestehenden Transformatoren eine Spannungserhöhung von 50’000 auf 110’000 Volt. CKW investiert mit diesen Projekten rund 11,5 Mio. Franken in die Sanierungen und den Ausbau der Netzinfrastruktur. Sie stärkt damit heute und in Zukunft die Versorgungssicherheit in den Regionen Horw, Kriens, Littau und der Stadt Luzern.

    Halter redesigns the center of Wetzikon

    With the demolition of buildings in the northern part of the planned new development, the Schliere-based construction company Halter AG has started to redesign the center of Wetzikon . According to the media release , a lively center with shops, services and apartments is to be built there by the end of 2025. In the past two years, Halter AG, as the developer, has brought the project to construction maturity together with the Wetziker architectural office meierpartner . The investor is Turintra AG Zurich, represented by UBS Fund Management. The investment volume on the 9013 square meter area amounts to around 138 million Swiss francs. 

    The shell construction work for the building construction of the first stage is to begin in the spring. Delivery is planned for November 2023. The second stage should be ready for occupancy in November 2025. According to a statement by Halter AG, the superstructure offers space for shops and restaurants, public-oriented uses and a medical center. Rental apartments ranging in size from 2.5 to 4.5 rooms for different target groups are being built on the upper floors. Some of the rental apartments are offered according to the MOVEment concept, in which electronically movable room elements create living comfort in a small space.

    114 apartments and 35 MOVEment apartments are planned. 3,100 square meters are planned for the services area, and 4,600 square meters for sales and gastronomy. Garages for 176 cars, 34 motorcycles and 450 bicycles will be created.

    A central city lane for pedestrians and passers-by and a city square are to be created in Wetzikon. A "Spanish Step" is intended to serve as a cross connection between Bahnhofstrasse and Jörg-Schneider-Park as well as the Wetzikon vocational school.
