New Inwilerstrasse overpass

The Zug – Baar bypass (TZB) will give the higher-lying municipalities in Canton Zug direct access to the motorway. To allow the new road to be crossed by pedestrians and cyclists, one measure that has been brought forward involves the construction of the new Inwilerstrasse overpass. A two-bay, 66-meter-long, slender steel structure will be constructed on the greenfield site. The bridge will be prefabricated and transported to the construction site in three parts, where it will be welded together.

In this project, Gruner Berchtold Eicher AG has formulated the main design, the plans for public display, the tendering procedure and the detailed design. Planning took place in the engineering consortium together with Emch + Berger WSB AG and Pöyry Schweiz AG.

Main­ten­ance plan­ning N02 Reiden - Sursee

EP N02 Reiden - Sursee: Ausführungsplanung und Realisierung der Instandsetzung des Autobahnabschnitts

The highway section of the N02 runs between Reiden and Sursee in the "Uffiker Moos" over ground that is prone to subsidence. When doing repairs, future subsidence must therefore be assimilated to the natural subsidence trajectory as much as possible. Measures for a 15-year extended period of use, which take this criterion into account as best as possible while maintaining economic efficiency and minimum use restrictions, are to be planned.

The trade union KoBeGru, which consists of the companies Kost + Partner AG, Sursee, Gruner Berchtold Eicher AG, Zug as well as Gruner AG, Basel, was commissioned with the planning and implementation of the repair of this highway section.

Protective Measure Groundwater Capture Drälikon, Hünenberg

Schutzmassnahme Grundwasserfassung Drälikon, Hünenberg

In the municipality of Hünenberg in the canton of Zug, an extremely efficient filtering well is used to supply drinking water in the Drälikerboden area. The existing cantonal road runs along this groundwater capture in groundwater protection zones S2 and S3. The infiltration of polluted surface runoff from the road is not permitted in groundwater protection zones. Therefore, various measures to protect the groundwater and treat the road runoff were evaluated. A sealed trough/ditch system in the grassy median between the road and the bike path/sidewalk was determined to be the best alternative.

The new drainage system requires 515 m of perforated and 600 m of collection pipelines. As part of the main works, the existing Riedhofbach culvert will be replaced with a new structure, and a total of 1,100 m of drinking water pipelines will be renovated.

The services provided by Gruner Berchtold Eicher AG include the already completed alternatives study, the construction project and the construction permission design as well as the upcoming final planning with site supervision.

Technical Article: Room Acoustics at Low Frequencies

Markus Ringger and Thomas Herzog (both from Gruner AG’s Structural and Room Acoustics Department) called on their comprehensive knowledge to write a technical article on room acoustics at low frequencies (German).

Usually, fiber absorbers are used to reduce the reverberation time in rooms. These must be the correct thickness and be installed at the correct distance from the ceiling or wall. However, narrow spatial conditions sometimes do not allow for this. In this case, other materials, such as stud walls, plasterboard, membrane absorbers or composite resonators, are required.

The article was published in Applica, the trade journal for the painting and plaster trades, in March 2017.

Reopening of the Indoor Pool Buchholz, Uster

Hallenbad Buchholz, Uster

Aesthetics are important; profitability is a main focus, and the consideration of eco-friendly options goes without saying – but safety is the top priority.

A structure optimally suited to the indoor pool climate and capable of bridging large spans was needed. This task was mastered with architectural finesse, creative engineering skills and innovative craftsmanship. The result is a long-lasting and robust structure with continuous wood beams and a clear load-bearing capacity for both vertical and horizontal forces.

Gruner Wepf AG, Zürich completed all phases according to the Swiss Society of Engineers and Architects (SIA) for both the reinforced concrete component and the wooden construction. In addition to a preliminary status analysis of the existing hall, the repair of old structures was supervised and civil engineering works, including excavation, were planned.

Overpass ramp at the Sitter Viaduct in St. Gallen

230 tonnes in weight, 106 meters long, approx. 10 meters wide and installed in just one night – these statistics describe the temporary overpass ramp that has been installed over the carriageway under renewal and which makes it possible to replace expansion joints without disrupting traffic flow.

At 675 meters in length and 60 meters high, the freeway bridge between St. Gallen Winkeln and Kreuzbleiche is the largest bridge on the St. Gallen urban freeway network, a central arterial route through eastern Switzerland. "The replacement of two expansion joints on the Sitter Viaduct is an urgently needed sub-measure in the planned overhaul of the urban freeway," explains project manager Stephan Hofer from Gruner Wepf AG, St. Gallen. Providing protection from moving traffic, shelter from bad weather during the work and shorter construction times have been compounded by further challenges, including the low working heights of between 1.60 and 1.80 meters and noise emissions of around 100 decibels. Gruner Wepf AG, St. Gallen, is lead-managing the planning, implementation and ongoing preliminary works for the refurbishment of the entire section.

One name is resonating around the world – Gruner

Ein Name geht um die Welt – Gruner, Collage Gotthard

From New York to Shanghai, from Amsteg to Anchorage:

at the opening of the Gotthard Base Tunnel on June 1, 2016, the entire media, whether TV, print or online, were talking about Gruner – Eduard Gruner.
It was he who began the realization of the once-in-a-lifetime project and who put specific, feasible plans onto paper an incredible 69 years ago.
“The new timetable comes into effect today, May 5, 2000. (...) The express train completes the journey from Basel to Chiasso in just two hours – a journey that would have taken over five hours fifty years ago.” These were Eduard Gruner’s musings on his vision of a Gotthard Base Tunnel, which were published in “Prisma”, a technology journal, in August 1947. He was the only person who had this vision, and had already been working on it for 17 years before this publication. This vision is now a reality.

 

Although his estimates in terms of project cost and construction time are not in line with today’s figures, top experts are still extremely impressed about how concrete and detailed Gruner’s plans were, even then.
Gruner’s Gotthard Base Tunnel plans did not just envisage a track for the railroad, but rather a two-story construction in which there would also have been space for a freeway above the train. His initial notes and sketches were all ground-breaking. Even then, Eduard Gruner predicted that the workers in the tunnel would have to deal with temperatures of 45 degrees Celsius – and he was right.
Eduard Gruner sadly did not see the tunnel become a reality – the genius visionary passed away in 1984. But the Gruner name, and thus the Gruner brand, resonated around the world on June 1, 2016.
Several teams from the Gruner Group have been working on the planning and realization of the world’s longest rail tunnel since 1994. And we are proud of that.

We send our congratulations on the opening of the Gotthard Base Tunnel

Gotthard-Basistunnel

Living history 

Interview with Michael Bont (50), Head of Infrastructure, Gruner Ltd

As a young engineer, you were already working for Gruner Ltd on the once-in-a-lifetime Gotthard Base Tunnel project back in 1994. What did it mean to you then?
At that time we were commissioned to conduct the safety-oriented investigation (SIOP) of all tunnel pre-projects along the entire Gotthard route, from Zurich and Lucerne to Lugano. As a young engineer, I had the opportunity to study and analyze virtually all of Switzerland's combined tunnel-building expertise. I found it enormously valuable to 

 

participate in the particularly interesting site visits and technical discussions, alongside the project authors and our tunnel construction experts. I ended up being bitten by the tunnel building bug myself.

You worked on the Gotthard Base Tunnel for about 15 years. What did you find most fascinating about this project?
The many political, technical and economic challenges posed by this unique project are fascinating, of course, but I was even more impressed by the innovative genius of the engineers and the construction industry. When we started, it was first necessary to develop new and innovative construction methods in order to cope with the huge rock pressures, as well as new sealing systems, special concrete mixes, etc. Solutions were found for each and every problem, and their feasibility and usability verified through tests developed specially for the purpose. I have also been impressed by the extremely professional project management of AlpTransit Gotthard AG.

What thoughts are going through your head as the tunnel of the century finally opens?
"Rejoice, rejoice", is what our former Federal Councilor Adolf Ogi once said, when Claude Nicollier became the first Swiss astronaut to orbit the Earth, and I think that describes my thoughts exactly. Naturally, I am also very happy to be here for the opening of the base tunnel, as a member of Gruner Ltd. I am incredibly proud and motivated to know that our small country can produce tremendous feats that are unparalleled anywhere else the world. We should keep the tunnel in mind as an example when we go about our everyday work.

What advice would you give to young engineers with regard to developing a career?
Keep going and keep working on your skills, set yourselves ambitious targets, build on your strengths and use mistakes and failures as a way to improve. Be committed and play your part, but without losing patience. Invest in your team's performance, improve your communication and project management skills. And last but not least, never let work stop being fun.

Kariba dam site, Zambia

Kariba-Staudamm, Zambia

In the framework of a 300 million USD rehabilitation project, a team of Stucky experts visited the Kariba dam site in January. This technical assistance and construction supervision contract was recently awarded to Stucky by the Zambezi River Authority, and consists of two major components; the reshaping of the plunge pool to limit scouring and erosion that could potentially undermine the dam foundations, and the rehabilitation of the spillway gates and stop beams.

The Kariba dam and hydro-electric scheme, constructed between 1956 and 1959, is a double curvature concrete arch dam with a maximum height of 128m. The lake is over 223 km long and up to 40 km in width.

With a 9,000 m3/s maximum discharge capacity, the spillway is a critical element for the safety of the dam. The objective of the project is to guarantee safe operation including in case of a very large flood. The other key element is to reshape the plunge pool, where an 80m deep scour hole has formed in the bedrock immediately downstream of the dam foundations over the past 50 years.  This work is unprecedented in dam history and urgently needed to prevent any potential further regression and protect the dam from catastrophic failure due to lack of foundation support.

Rehabilitation of Fully hydropower installation

The Fully hydropower installation was put into service in 1915. Its turbines are driven by water from the Lac de Fully and Lac de Sorniot catchment basins. A hydropower plant known as the "Belle Usine" was built in Fully to make use of the gross head of 1643 meters, the highest in the world until 1934.

In 2011, Forces Motrices de Fully mandated Stucky Ltd to rehabilitate the installation. To guarantee the serviceability of the existing penstock, which had been affected by general corrosion, Stucky proposed reducing the pressure within the penstock by creating an intermediate level at Les Garettes. As part of the rehabilitation work, a new hydropower plant will be built in the valley at Verdan, while the pumping station will be replaced by a turbine at Sorniot. Construction of the hydropower plant and intermediate level started in September 2015.

Building services and energy systems for the Grosspeter Tower

The ground-breaking ceremony for the Grosspeter Tower took place on November 10, 2014 in Basel. The centrally located building complex will house commercial, office and hotel units. Gruner Gruneko AG was commissioned to plan the building services and energy systems. The energy concept is based on the use of geothermal probes to heat and cool the building.

To increase planning reliability and reduce the costs of building complex heating and cooling systems that use geothermal probes or groundwater, we have developed a practical method of coupling building, system, probe and groundwater flow simulations. This enables us to model the entire building and subsoil and view them as a whole in project development activities.

Gruner engineers specializing in building services, energy systems, hydrogeology and simulation are working closely together to plan the downhole heat exchanger arrays.

Combined heat and power plant flown in by helicopter.

In 2001, Gruner Gruneko AG was general planner for the renovation of the energy unit atthe "Wiesengarten" site in the Kleinhüningen district of Basel.

This year, the combined heat and power plant (CHP) was due for renovation.
The energy unit consists of an electric heat pump that uses ground water as its energy source, a gas-fired CHP, a gas-fired peak-load boiler and an oil-fired emergency boiler.

The CHP was flown in by helicopter on October 14, 2014, making a spectacular sight for passers-by. The video shows the exciting air-borne trip to the basement from the CHP's perspective.

Muttsee Dam, the last m³ concrete has been placed

At a ceremony on October 8th 2014 the last m³ concrete has been placed on the Muttsee Dam. Another dam designed by Stucky will soon start operation.

The Muttsee Dam, located at an elevation of 2'450 m a.s.l. will form the upper reservoir of the new 1'000 MW pumped storage plant Linthal 2015.

The Muttsee Dam has a length of 1'025 m, and is thus the longest dam in Switzerland. It consists of 68 mostly 15 m wide blocks. After the installation phase during the first two seasons 2010 and 2011, the main blocks of the dam were casted throughout three seasons between 2012 and 2014. Grouting and finishing works will continue in 2015. Another challenge besides the high altitude was the transportation of all mate-rial to the construction site via two cable cars and a tunnel.

Calibrated smoke tests in interior spaces

Real-time smoke tests can be used to investigate the efficacy of existing or new smoke evacuation systems and thereby guarantee that the goal of protecting people is achieved. We work with a patented mobile test system that was developed in compliance with GFPA guidelines and VDI (Association of German Engineers) Standard 6019. This system allows the scaled modeling of variously sized fire scenarios. Tests can be carried out in completed interior spaces without components or fittings being affected by critically high temperatures.

The video can be found here.

Gruneko AG receives recognition

Landesbaupreis Mecklenburg-Vorpommern 2014

The Friedrich-Löffler-Institut on the island of Riems (Germany) is one of the five most modern animal disease research institutes in the world – not least because of its new laboratory and stable buildings, which comply with the highest safety standards. For its specialist planning work in the area of building services, Gruneko AG has been awarded the Landesbaupreis Mecklenburg-Vorpommern 2014.

Research into highly dangerous viruses possible
In conjunction with BLS Energieplan GmbH, Gruneko AG planned the building services for the laboratories (24,000 m2) and stables (43,000 m2). The new buildings were successfully completed in 2011. One highly demanding aspect was to observe the special biosafety requirements in order to protect the environment, employees and products. As the new laboratories meet the highest safety standard, BSL 4 (Biosafety Level 4), it is now possible to conduct research into highly dangerous viruses.
