  • Alpine solar project launched over 2000 metres

    Alpine solar project launched over 2000 metres

    Axpo, based in Baden, has commissioned STRABAG to realise an alpine solar project next to the Lai da Nalps reservoir above the village of Serdun in Graubünden. Around 1,500 solar panels and a technology centre will be installed in the NalpSolar project at over 2,000 metres above sea level, the Schlieren-based construction company announced in a press release. The first 10 per cent of the plant is due to go into operation this December.

    “The construction work is technically demanding, logistically challenging and ecologically sensitive, but above all a milestone for the energy transition in Switzerland,” writes STRABAG. The individual solar tables and other components have to be transported along a narrow, single-lane mountain road. The road, which is normally closed, was built by Axpo in the 1960s as an access road for the reservoir.

    As there are no storage facilities on the construction site, only the material that is immediately needed is transported. “The logistics now run like clockwork,” explains construction foreman François Borner in the press release. “Instead of being stressful, it is now easy to plan.” In the press release, STRABAG cites the uneven ground and respect for the nature conservation zones in the construction area as further challenges in the project.

    Due to the altitude, NalpSolar will produce a lot of electricity, especially in the winter months, explains STRABAG. The construction company is aiming to complete the work in 2028. The electricity from NalpSolar is reserved for the SBB power grid for the next 20 years.

  • Expansion of district heating in Münchenbuchsee

    Expansion of district heating in Münchenbuchsee

    The Schlieren-based construction company STRABAG is creating a modern energy supply for the municipality of Münchenbuchsee with district heating pipes. According to a press release, STRABAG is laying around three kilometres of new district heating pipes to expand the district heating network in the municipality in Bern-Mittelland. Work began on 9 September and the first of around 15 stages has already been completed, according to STRABAG. Two further stages will follow by the end of the year, according to the company press release.

    Regarding the progress of the work, the company says that as residents still need access to their homes and garages, the road cannot be completely closed for the construction work. To install the district heating pipes, just under a quarter of the road will be opened up and the pipes laid. After each construction phase, the trenches will be temporarily backfilled with earth and a temporary surface will be laid. Over the next few months, the earth will settle. Therefore, once all 15 stages have been completed, the temporary surface will be milled off again and a new asphalt layer will be applied.

    According to STRABAG, the construction work is expected to be completed by December 2025 by the STRABAG Traffic Route Construction (VWB) team in Bern. “We are well on schedule so far and should complete the project on time,” says Lena Wagner, construction manager at VWB Bern.

  • Resource-conserving use of demolition materials in road construction

    Resource-conserving use of demolition materials in road construction

    Strabag has been using crushing technology from the manufacturer Gipo to process mineral demolition materials since July. The mobile stone crushing plant Gipo-P100 GIGA produces high-quality aggregates from mineral demolition materials for road construction and concrete production at the Bürglen gravel plant, the construction company writes in a press release.

    The Bürglen gravel plant has a mixed gravel deposit consisting of processed gravel as well as primary and secondary gravel material. Storage and landfill require space. Recycling, on the other hand, means that excavation materials can be reused for future construction projects while conserving resources.

    An excavator fills the hopper of the 74-tonne crushing plant with unsorted demolition material. The material passes through several crushing stages on a conveyor belt, is screened and separated from construction waste until the end product has the required grain size. This is then supplied to the concrete plants, which use the recovered concrete for road construction.

    The technical manager of the Bürglen gravel plant, Franco Martinelli, quoted in the press release, describes the performance of the new crusher using the example of a construction site in Flawil SG. There was an urgent and short-term need for 3000 cubic metres of crushed, unbound 0/45 mixture. “With the crusher, we processed the required material within three days and transported it directly to the construction site. Without our Gipo-P100 GIGA, we would have had no chance of supplying our operatives,” they say.

    Strabag is also planning to use the crusher directly on construction sites for major demolition and dismantling work in the long term.

  • Strabag builds roads in the Weitblick district of Solothurn

    Strabag builds roads in the Weitblick district of Solothurn

    The Schlieren-based construction company Strabag is carrying out work in the future Weitblick district of Solothurn to create a network of roads and paths as well as all utility lines. According to a press release, the new Weitblick district in Solothurn will be completed by 2036. The district will provide living space for around 1,700 people and accommodate the same number of jobs. There will be a new park and recreational space. Thanks to Weitblick, the city of Solothurn will be able to create new living space and space for new life in a central location, in the existing district structures and at the gates of the old town, the press release continues.

    According to the press release, Strabag has been involved in the project since the start of construction. In April 2023, Strabag teams began road construction work in the northern part of the site. Last September, Strabag laid the surface for the first road in Weitblick. After a construction break, the final work is now in full swing and the job will be completed in this part of Weitblick in the next few weeks. Construction work in the southern part of the Weitblick site is currently in full swing, according to Strabag.

    The subsoil in this area is also difficult to build on due to the high groundwater level. Sheet piling, bored piles and a lowering of the groundwater level were therefore necessary. All special civil engineering work was carried out by Strabag. The trenches for the utility lines are currently being excavated and the access roads for the Weitblick site are being constructed.

  • Strabag opens first site in western Switzerland

    Strabag opens first site in western Switzerland

    The construction company Strabag AG from Schlieren is expanding into western Switzerland. A new site was opened in Morges on the northern shore of Lake Geneva on Wednesday, 12 April. According to a press release, the company will offer special civil engineering services, including excavation work, large and small-scale drilling, sheet piling, dewatering and well construction.

    The first project to be realised is the Viaduc de Malley tramway project for Tramway Lausannois. Strabag is laying the foundations for the piers and abutments of the rail track. For this, 32 large bore piles with a diameter of 130 centimetres and a depth of up to 17 metres are being installed.

    “With the expansion of our special civil engineering to Morges, we are extending our reach and competencies to western Switzerland. Close local cooperation with clients and partners is planned,” Günter Moser, technical director of Strabag AG, is quoted as saying. The construction company already has 20 locations in German-speaking Switzerland. The parent company Strabag SE is active worldwide, with a focus on Europe, Saudi Arabia and the Gulf region, Africa and Australia.

    Enquiries from French-speaking Switzerland have increased recently, according to Strabag. “We have already carried out a number of projects in the region in the past and have positioned ourselves successfully,” Mike Albinus, commercial division manager for special civil engineering, is quoted as saying.

  • Strabag builds modern skate park in the canton of Uri

    Strabag builds modern skate park in the canton of Uri

    The construction company Strabag from Schlieren is building the first modern skate park in the canton of Uri. According to a media release, the groundbreaking ceremony took place at the Selderboden leisure facility in the municipality of Silenen on Monday, 20 March. The municipality had designated the 1300 square metre site after more than ten years of planning.

    The Freestyle Uri association decided on concrete as the building material. According to the Strabag statement, this has advantages. On the one hand, the perfect running characteristics and on the other hand, the weather resistance and reduced maintenance costs compared to parks made of wood or sheet metal.

    In addition to public use for all skill levels and ages, events and competitions as well as training sessions and workshops are to take place in the future. The skate park is scheduled to open on 12 August.

    Strabag says it will also use skate sports enthusiasts among its apprentices at the Erstfeld and Disentis/Sedrun sites for planning, surveying and construction. They will help with surveying and masonry work. The assignment will be accompanied by a filmmaker who will document the work of the apprentices on the construction project for Strabag. The company plans to use the resulting film to advertise for apprentices.

    According to the press release, the total costs amount to 870,000 Swiss francs. They were raised through the association’s own funds, fundraising campaigns, donations, public funds, foundations and sponsors. Strabag is also one of the sponsors.

    “We are very pleased to support the skatepark crew in their project. They have put an incredible amount of energy into this project over many years and have managed to make it fly,” Jonas Aschwanden, technical division manager for civil engineering, is quoted as saying.

    The district school Gäu in Neuendorf is expanded by a new building. Hochbau Oensingen, a department of the Schliere-based construction company Strabag AG , is responsible for the building shell with core zones and facades. According to Strabag's press release , the new school building consists of four floors: the basement with underground parking, the technical center, the materials store and the meeting room. On the ground floor, the entrance area, the auditorium and the staff room are created. The new classrooms are located on the two upper floors. The existing building and the new building are connected underground with a passage. The new building should be ready for occupancy in autumn 2023.

    Regarding the construction, the announcement states that a building made of exposed concrete with a wooden structure is planned. Glazed formwork elements and wooden panels with vertical indentations are intended to create the desired exposed concrete structure after concreting.

    The district school Gäu in Neuendorf runs the secondary school for Neuendorf and the surrounding communities. The increasing number of pupils in the associated municipalities requires additional school space, according to the statement. According to the website of the Zweckverband Kreisschule Gäu , the upper school students come from the district communities of Egerkingen, Fulenbach, Härkingen, Neuendorf, Niederbuchsiten, Oberbuchsiten and Wolfwil. Around 440 students are currently being taught by 60 teachers.

    Strabag is an active partner on Engineers' Day

    Strabag Switzerland will take an active part in the day of engineers and will present a pilot project in Küsnacht in an online lecture. According to the media release from the Schlierem construction company, the start is on Friday, March 4, at 11 a.m. The lecture goes until 12:15 p.m. and will be broadcast on the Internet via Microsoft Teams. On the Engineer’s Day website, access is possible by clicking on it without prior registration. The speakers are Stijepan Ljubicic, Technical Group Manager BIM, and Christian Häni, Technical Group Manager Traffic Routes Engineering at Strabag.

    BIM stands for Building Information Modeling and describes the model-based planning, implementation and operation of construction projects, with the aim of optimizing the transfer of knowledge, the quality of the results and the efficiency of all those involved, according to Strabag. On March 4th, Strabag will present its project for the renovation of the Schiedhaldensteig in Küsnacht in the live presentation. Strabag is the total contractor and is responsible for the planning and construction management as well as the execution – model-based using the BIM 5D program. In Küsnacht, the upper part of the Schiedhaldensteig was rehabilitated in a very narrow and steep traffic area and the sewage pipes were replaced. At the same time, the existing gas, water and electrical lines at the plants on Lake Zurich were renewed.

    Even before the actual Engineer’s Day, a networking event will take place on Thursday, February 17, at the JED in Schlieren. Zurich government councilor Carmen Walker Späh and Federal Councilor Guy Parmelin will be taking part. According to a press release from the Limmatstadt AG location promotion, a panel discussion will highlight the qualities and potential of engineers from various disciplines.

  • 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".
