BAUER AG

By the time the climate-friendly neighborhood in Frankfurt’s Hilgenfeld district is completed, the team from BAUER Resources GmbH with its three drilling rigs will be long gone. It will be almost like they were never even there. “Almost” being the key word. What will remain is an impressive geothermal probe system that was installed on behalf of regional energy supplier Mainova AG. With seven distribution shafts, numerous pipelines and more than 50 m³ of brine, the system is impressive not only because of its scope: this is an exceptional project in many regards.

19,200 m drilled in eight months

Over the course of eight months, the three drilling teams from Bauer Resources completed their work on seven geothermal fields for the installation of the geothermal probe system. More than 19,200 m were drilled and a total of 160 geothermal probes from GWE GmbH were installed up to a depth of 120 m. “The grouting work in later stages took a particularly long time, since considerable extra quantities were consumed in some areas. This required precise coordination between the different parties involved in the project,” explains Site Manager Raphael Werner from BAUER Resources GmbH, adding: “To ensure optimal quality for the backfill material in the boreholes, we used a specially developed, magnetically marked and thermally improved slurry. After completing the drilling work, we inspected the seal with a magnetic probe to ensure that it was executed properly – this is how we achieve optimal groundwater protection.” The excavation work for the pipe trenches began simultaneously with the drilling work. Then it was time for the most arduous task: The experienced team laid more than 10,000 m of pipeline. Finally, the connections were established and the trenches were backfilled with soil. To fulfil the strict quality requirements, all work steps were painstakingly documented, construction materials were carefully monitored and the lines were regularly subjected to pressure tests. “Thanks to precise execution, we were able to move forward rapidly with the project,” continues the Site Manager.

Demanding soil conditions

The project is unusual not only because of its magnitude and the effort involved, but also because of the particular soil: The surface level of the 17.7 ha site is covered with glacial loess loam. This is one of the most valuable soil types in the world. “For this reason, protecting the soil was a top priority. None of the construction vehicles were allowed to drive directly over the grounds. Instead, extra access roads were built and the soil was protected with wood chips and load distribution plates,” explains Raphael Werner. The deeper stone strata also posed multiple challenges: On the one hand, the drilling equipment had to be adjusted frequently because of the varying soil strata. Furthermore, flushing losses occurred unexpectedly. “Not an easy undertaking, but ultimately no problem for us. In some cases we flushed the boreholes differently, in some areas we adapted the casings,” remarks experienced Operations Manager Marcel Mößlang of BAUER Resources GmbH.

Where implementation ends, maintenance begins

Even after finishing the main work, there are some tasks left for Bauer Resources: Until 2029, the experts will take care of maintenance on the geothermal probe system including flushing, filling and fine-tuning. “In Frankfurt we are offering our full range of services, from design and execution to commissioning and even maintenance.” During the next stage, an innovative climate-friendly district will be constructed on the 17.7 ha site, which will serve as a shining example far beyond Frankfurt and Hessen thanks to the sustainable energy concept for heat and power supply furnished by regional energy supplier Mainova AG. This district, constructed by state residential construction company ABG FRANKFURT HOLDING GmbH, will house a total of 54 apartment buildings, 860 residential units as well as commercial spaces. “We will remember this project for a long time, because a geothermal energy system of this magnitude is rare – this is one of the largest of its kind in all of Germany,” says Marcel Mößlang in summary.

The Annual General Meeting of BAUER AG was held on 19th September 2024. Around 250 shareholders, guests and press representatives gathered at the company headquarters in Schrobenhausen. They listened with great interest to the remarks by Executive Board Member Peter Hingott, who first reported on the preceding financial year: “2023 was an eventful, but successful year for us,” he summarized.

Despite the numerous changes and challenges both in the company and in global politics and business, Bauer succeeded in increasing total Group revenues to 1,831.1 M € in 2023 and achieving EBIT of 95.2 M €. In addition, the syndicated loan could be extended ahead of schedule. “Our annual result is particularly remarkable against the backdrop of a cyber attack on our IT infrastructure at the end of October 2023,” emphasized Peter Hingott.

And the positive development has continued so far in the current financial year: “We have made a good start to 2024 and are on schedule after the first half of the year,” says Hingott. “The Group’s order backlog and order intake have once again risen significantly – the growth comes from all three segments, but especially from special foundation engineering. We therefore expect to continue to achieve our targets for the Group and to increase total Group revenues and EBIT.”

However, the Executive Board of BAUER AG also pointed out that the market in Germany had weakened further, as construction investment had declined due to inflation and rising interest rates. “It can be assumed that 2025 will be challenging for us in Germany, and we have been preparing for this for some time. Price and competitive pressure in the Equipment segment is also increasing, as the Chinese construction market, which has been weak for years, is causing local manufacturers to increasingly push into European markets.”

Peter Hingott also provided information about current and planned investments, including in the main plant in Aresing, but also in subsidiaries such as Klemm in Drolshagen.

During the vote, the shareholders then voted on the proposed resolutions on the agenda items, as a result of which, among other things, the conversion of bearer shares to registered shares is now to be completed. The proposal to elect Sebastian Sennebogen and Florian Tucher Freiherr von Simmelsdorf to the Supervisory Board as new members of the shareholder side also met with broad approval. In return, long-standing members Elisabeth Teschemacher and Gerardus N. G. Wirken will leave the Supervisory Board of BAUER AG. “Both have accompanied the company for many years. You deserve our extraordinary thanks for your work and support,” says Peter Hingott.

Schrobenhausen/Germany – A long-established tradition continues: For more than 35 years, BAUER Spezialtiefbau GmbH has been hosting the “Schrobenhausener Tage” lecture series. In April it was time again. This year’s motto: Focus Construction Site – stay tuned to Geotechnical Solutions. A total of roughly 300 guests attended from Germany and abroad, including participants from Japan who didn’t want to miss the event. They were all treated to a successful blend of fascinating presentations about spectacular construction projects in Germany, challenging international projects and the latest innovations in specialist foundation engineering. But that was far from all: another topic on the agenda was artificial intelligence.

Frank Haehnig, CEO of BAUER Spezialtiefbau GmbH, welcomed the guests and then handed over to Florian Bauer, Managing Director of BAUER Spezialtiefbau GmbH and moderator of the event. “You will see that the latest developments in specialist foundation engineering are very exciting. It’s not just our innovations and methods, but also the use of artificial intelligence that opens up countless opportunities and prospects for our sites,” remarked Florian Bauer.

From Germany…
The event kicked off with a lecture block addressing spectacular projects in Germany. Karsten Kegelbein, Site Manager for BAUER Spezialtiefbau GmbH in Hamburg, started off the series and presented a construction project in Helgoland. Surrounded by one-of-a-kind scenery there, Bauer implemented four different injection methods – far from a typical endeavor. In the next lecture, Susanne Nefzger, Head of Sales Bavaria for the South region, and Daniel Junger, Site Manager for BAUER Spezialtiefbau GmbH, presented a project for flood protection in the Bavarian town of Feldolling. A spectacular project with (almost) everything that specialist foundation engineering has to offer. Excavation pit monitoring during the CEFAM project in Cologne was addressed by Agnes Demharter, Site Manager at BAUER Spezialtiefbau GmbH, and Project Manager Andreas Hertenberger from the domestic business division. The morning’s lecture series was rounded off with an interesting guest presentation on “Monitoring of Geotechnic Works – the basis for sustainable and intelligent Geotechnics” by Prof. Dr. Christian Moormann from the Institute of Geotechnical Engineering at Stuttgart University.

During the lunch break, participants were able as usual to explore the innovations in specialist foundation engineering through an exhibition at the stands for the Technical Services, Design and Digitalization departments. Furthermore, in the exhibition area for the in-house exhibition of BAUER Maschinen GmbH starting several days later, an impressive array of equipment was presented along with ample opportunity to engage in dialog directly with experts in the field.

…to the entire world
Refreshed from their lunch break, the guests returned for the second thematic section of the event. This was entirely dedicated to international challenges. The first report was given by Shekhar Battacharjee, Senior Manager Business Development at BAUER Engineering India Private Limited, who discussed a subway project in the Indian metropolis of Chennai. Onur Askin, Technical Engineer at BAUER Spezialtiefbau GmbH, followed by presenting an impressive offshore project off the French Atlantic coast near Saint-Brieuc, as part of which Bauer installed 190 offshore piles for 62 wind turbine sites. Finally, Keith Ryan, Managing Director of BAUER International UAE, addressed the particular challenges involved in a construction project in Dubai for which the barrette foundations were implemented through an existing three-story basement level.

Digitalization and AI
The third and last thematic section of the event took a look at the future and digital challenges. Michael Jones, Managing Director of International Business Development at BAUER Technologies Limited, and Joachim Gaus, soil mixing expert in the Major Project Sales department, discussed the complex soil improvement measures that were carried out under water in 2023 working from a pontoon in Sweden. Marcus Daubner, Head of Digitalization, addressed the digital twin and presented specific practical examples. Richard Gutjahr, freelance journalist, moderator and blogger, concluded with interesting insights about the topic “Artificial intelligence – Hype or Change”.

This was followed by a final panel session with Christian Moormann, Richard Gutjahr, Marcus Daubner and Frank Haehnig in which the opportunities and prospects for artificial intelligence in specialist foundation engineering were thoroughly discussed. “We have a passion for progress and we are open to new ideas,” emphasized Florian Bauer. “In specialist foundation engineering, great opportunities await us through the use of AI, which we are tackling together.”

As usual, the traditional event concluded with lively discussions during a relaxed Bavarian dinner with regional specialties and authentic local music.

BAUER Spezialtiefbau GmbH is dedicated to more than just foundations. The company has set itself the goal of establishing the sustainable construction site as a standard and making a key contribution to a green future. Just last summer, the company was awarded the DGNB certificate for sustainable construction sites. Now another sustainability milestone has been achieved: On February 23, Florian Pronold, retired Parliamentary State Secretary and Managing Director of the Institut Bauen und Umwelt e.V., handed over six environmental product declarations for the Mixed-in- Place method (MIP) to representatives from Bauer Spezialtiefbau, including Managing Director (CEO) Frank Haehnig and Member of the Management Board Florian Bauer. “I am thrilled to present BAUER Spezialtiefbau GmbH with these environmental product declarations. Not only does this step underscore their commitment to transparent and sustainable specialist foundation engineering, it also sets whole new standards,” remarks Florian Pronold.

Basis for ecological assessment

Environmental product declarations, known as EPDs, deliver transparent environmental impact data verified by independent experts. This is a verifiable and transparent way to integrate the environmental compatibility of construction products into the assessment of a structure’s sustainability. Starting from the design phase, this extensive information is useful for designers, architects and owners. It allows them to make justified decisions for sustainable construction methods, for example by considering the carbon footprint.

Furthermore, this ensures that environmental compatibility requirements are fulfilled for a structure across its entire lifecycle. The EPDs serve as a basis for the ecological assessment of structures in accordance with DIN EN 15978. These declarations are coordinated at the international level and are based on ISO standard ISO 14025 as well as the European standard EN 15804.

Green milestone

“Our initiative with a total of six EPDs for our Mixed-in-Place method represents a significant milestone in the construction industry,” emphasizes Dr. Hursit Ibuk, Head of Construction Materials Technology and Product Sustainability at Bauer Spezialtiefbau. In the past, no environmental product declarations existed for construction products that were prepared directly on site using raw materials. The EPDs now encompass both the manufacturing process for the MIP material as well as the MIP method itself.

Efficiency meets sustainability

For more than 30 years, the Mixed-in-Place method developed by Bauer has proven successful for implementing retaining structures, foundation measures and flood protection. What makes this method unique: The construction material is produced on site in a sustainable and resource-efficient manner. “Thanks to many years of expertise, our employees’ know-how and continuous ongoing development of the drilling and mixing tools, the Mixed-in-Place method can now be implemented in nearly all soil types,” explains Dr. Hursit Ibuk. With a general type approval from the German Institute of Construction Technology, the MIP method can also be used for particularly challenging construction tasks.

Frank Haehnig, Managing Director (CEO) of Bauer Spezialtiefbau GmbH, proudly summarizes: “The environmental product declarations for our Mixed-in-Place method demonstrate very clearly that sustainability is not just a concept for us: it is our passion.”

On October 16, 2023, the headquarter of BAUER Maschinen GmbH in Schrobenhausen, Bavaria/Germany hosted the kick-off event for a research project with the potential to catapult the carbon footprint of specialist foundation equipment to a whole new level. The goal: climate-neutral operation based on a fuel cell system. The consortium partners are BAUER Maschinen GmbH along with the Professorship for Fluid Systems Technology and the Chair for Fluid Mechanics at the Friedrich-Alexander University of Erlangen-Nuremberg.

A machine from Bauer as a basis

Over the next three years, the project partners will work together to develop a concept for operating construction equipment in specialist foundation with zero CO2 emissions. The plan is to integrate a drive system comprising a hydrogen fuel cell, along with all necessary peripheral components (“balance of plant”), into a special foundation machine from BAUER Maschinen GmbH. The fuel cell system along with other required components such as H2 storage unit and cooling unit are designed as a plug-in module for universal use.

Reducing noise emissions

Within the project, operating strategies for fuel cells and backup batteries are evaluated with regard to the technical requirements. Another focus of research is the targeted influencing of noise emissions, which negatively impact both equipment operators and the environment during the operation of construction equipment. With the aid of aeroacoustics simulations and resulting measures to reduce noise, the aim is to significantly reduce emissions compared to conventional, diesel-powered equipment. At the end of the project, the plug-in module will be installed on a Bauer machine and tested in practical application.

Logical further development

The research project planned for three years, with its official title “Modular drive system with fuel cells for applications in specialist foundation engineering” (MABAS), has received funding from the Federal Ministry for Economic and Climate Action as part of the 7th Energy Research Program, a grant of approximately 2.5 million euros. The project represents another logical step towards the goal of sustainability: Following Bauer’s previous contributions to sustainable construction with the cable-bound eBG 33 and battery-powered eBG 33 H all electric, the use of hydrogen technology in the form of a fuel cell is a logical enhancement. A hydrogen-powered machine can be used anywhere a cable connection is impossible or specific services are required that cannot be provided to the necessary extent using only batteries.

Dubai, UAE – For two weeks, the eyes of the world were on Dubai: December 12th was the final day of “COP28”, the 28th UN climate conference. The focus: Nothing less than the future of our planet, in a year that is likely to be the hottest year ever. Approximately 70,000 people, including politicians, journalists, consultants and climate activists took part in the conference. One of them was Shahad Al-Zakwani. As a representative of BAUER Nimr LLC, the Omani subsidiary of BAUER Resources GmbH, she presented a unique project to reduce CO₂ emissions using nature-based solutions.

Harnessing the power of nature

For the past 12 years, BAUER Nimr LLC has been operating the world’s largest commercial reed bed treatment plant system in Oman. With an area of 13.5 km², it is roughly the size of 1,600 football fields. From 2009 onwards, it has transformed a former desert landscape into a thriving oasis full of life. At that time, Petroleum Development Oman (PDO) commissioned Bauer to develop, build and operate a nature-based and sustainable water treatment system.

Natural flow processes instead of energy-intensive pumps

What makes the green water treatment system unique is not only its enormous size and remarkable cleaning capacity, but also the new standards it sets for sustainability. By treating and reusing the produced water in a gravity-flown wetland, it is possible to avoid reinjection of the produced water eliminating the requirement for energy-intensive pumping. The groundbreaking result is the avoidance of more than 225,000 tons of CO₂ annually. The emission reduction project is now registered with the Global Carbon Council. Since 2021 it has been generating verified carbon credits that meets the requirements of CORSIA, the aviation industry’s carbon offsetting and reduction scheme. In addition, the project has been Diamond Labelled for its positive ecological and social impact. It will continue to generate carbon credits that can be transacted in the voluntary market until 2030.

Positive effects on biodiversity

Apart from the advantages for the environment, the project also makes a substantial contribution to biodiversity in the region, as different wetland plants are used for the treatment and reuse of the water. Numerous birds and wild animals have resettled in the project area. And in other respects too, the project is a remarkable success: By creating short- and long-term jobs, it will contribute to the economic development of the region for another 20 years.

A Call for Nature-Based Solutions across the Middle East

“Our participation in COP28 highlights our commitment to sustainable solutions,” emphasized Dennis K. Alexandersen, Business Development Director at BAUER Resources Middle East. “The water treatment project in Nimr is an example of our commitment, power of innovation and sense of responsibility towards the environment. We are convinced that nature-based solutions are central to addressing the pressing environmental challenges in the Middle East, both in the oil and gas industry and in the treatment of industrial and domestic wastewater.”

High throughput, fast assembly, digital operation with remote maintenance: that’s the new BE 600-C desanding plant from BAUER MAT Slurry Handling Systems. The Allgäu branch of BAUER Maschinen GmbH recently brought it on the market as a successor of the established BE 550 that truly keeps it all together: This two-stage plant with double cyclone design is installed within a container frame, and includes a reservoir tank, solids discharge, hose guide, all-round access platform and upstream coarse screen. It delivers 174 kW of power and a considerable throughput capacity of 600 m³/h. This means that the plant can process up to 120 t of solids per hour – setting new standards in the field of desanding.

Two become one

There’s a whole lot of established technology in the BE 600-C, since strictly speaking it’s comprised of two standard Type BE 300-C desanding plants. However, the optimized separation is new: After being fully treated in a first step, the slurry is pumped through the second tank inside (rather than outside) the plant toward the desilter unit. Another feature is the comparatively low space requirement, as pumps and desilters are located within the container frame and not outside, as would be the case for standard double cyclone plants. The BE 600-C thus achieves a base area of just 6.1 x 5.9 m.

But that’s not all: Because all components are installed within the container frame, it is possible to carry out transport, assembly and commissioning on site, quickly and easily – for example for cutting, tunneling, grabbing or drilling projects. What makes it unique: As needed, the BE 600-C can be divided back into two individual BE 300-C units, and the upstream coarse screen can also feed just a single unit. “This makes our plant as flexible as our customers’ projects,” summarizes Tim Eberwein, Sales Manager at BAUER MAT Slurry Handling Systems.

Focus on digitalization and automation

The BE 600-C also excels when it comes to digitalization with several new features, explains Yilmaz Ipeksoy, Technical Manager at BAUER MAT Slurry Handling Systems: For example, each of the two individual plants features a 12-inch display with touch screen. The complete plant can also be operated from a single screen in master-slave mode. The operator can see at a glance which parts of the equipment (conveyor belt, flow meter, accessories etc.) are running and which are not; other information such as pressures, operating hours or power consumption is also displayed. An EWON router establishes a connection with the Internet, which allows all data to be called up via remote access, along with error messages. “In this way, our service specialists can connect to the equipment quickly and easily and perform a remote diagnosis if necessary. This saves lots of time as well as costs, since our customers don’t have to wait for service technicians to arrive on site.”

Anywhere bentonite or cement slurry needs to be mixed, this MAT equipment can be used. “Whether for mixing, pumping, stockpiling or separating, our products are a key element of the complete cycle,” explains Kurt Ostermeier, Head of Product Management Mixing and Separation Technology at Bauer Maschinen. More than 30 years of expertise in mixing and separation technology contribute to the process when equipment or components are newly developed or enhanced at BAUER MAT Slurry Handling Systems. But new trends such as digitalization and automation are also in focus. Kurt Ostermeier asserts: “Digitalization as well as automation are ongoing processes that will continue to play a major role in the future. Our goal is to fully and permanently integrate our equipment into the cycle of a digital site.” And with the new BE 600-C, BAUER MAT Slurry Handling Systems has taken a major step towards that goal.

Bauer brought its first cutter to the market almost 40 years ago, thereby starting a success story that has now introduced a new chapter: In April, the company presented its new BCS 185 cutter system, which has really struck a chord with customers. “Our multi-functional MC duty-cycle cranes are used for a wide range of applications, first off as base carriers for our cutters and grabs, but also for lifting work or dynamic soil compaction,” explains Leonhard Weixler, Head of the Diaphragm Wall Division at Bauer Maschinen. “For anyone who doesn’t require this multi-functionality but needs equipment that is specially optimized for trench cutting, we have extended our BCS portfolio with the newly developed BCS 185. And the feedback from our customers is excellent.” This latest model of BAUER Cutter Systems (BCS) can cut trenches up to a depth of 90 m. In addition, the special design of our BCS systems combines proven technology with a vast variety of other useful features as well as the necessary modularity for today’s ever stricter transport requirements.

Solide base
The base carrier is a Bauer MT 185. The solid design offers high stability and comprehensive HSE features, including a rear view camera, integrated service platforms and ergonomic, highly comfortable cab layout. Operators used to our Bauer MC models are sure to feel at home quickly, since the inner workings of the cab are identical to the Bauer duty-cycle cranes. A variety of electronic assistance systems (integrated into the latest version of the BAUER B-Tronic system) supports the operator effectively and increase productivity at the same time. The MT 185 is equipped with a fuel-efficient, powerful Volvo engine, which complies to all different emissions standards worldwide.

Continuously adjustable cutter position
The BCS 185 is of course also available with the Bauer Turning Device, which allows this cutter to work in extremely confined construction sites and will still be able to ‘cut the corners’. “This is making the difference in today’s cutter operations,” remarks Leonhard Weixler. It allows the cutter to be twisted within a range of -50 to +95 degrees from its normal position to reach every corner in the excavation pit without a problem. Together with the overall compact dimensions of the BCS 185, the range of efficient cutter applications under restricted space conditions is further enhanced.

Streamlined special equipment for mid-sized applications
Attentive observers will also notice the arrangement of the hose drums in the boom, thanks to which the cutter system delivers a highly streamlined impression overall. The 30 t winch was specifically designed for use in the mid-sized range. With the maximum hook load of 43 t, the BCS 185 can be equipped with a wide range of Bauer cutters allowing trench widths of up to 1,500 mm. This makes the system as a whole even more attractive: The Bauer cutter system is not subject to crane permit regulations, hence any requirements for the operators are eliminated.

First operations in China and Europe
Just on display at Bauer’s In-House Exhibition in Schrobenhausen as well as in a product launch event in Tianjin in China, the new cutter system already started its operation in the South of China. It had been shipped to the construction site beginning of June and was assembled in a record time of only 22 hours. The first unit in Europe will soon travel to the French city of Toulouse. This BCS 185 will be used on a cutter project together with other Bauer cutters. “The BCS series, our MC-based cutter systems as well as our world novelty, the BAUER Cube System complement one another fantastically,” Leonhard Weixler remarks confidently. “And with that, Bauer once again demonstrates why we are the leading manufacturer of the worldwide most productive cutter systems!”

Cementation Skanska and BAUER Maschinen GmbH have jointly brought the world’s first electric, large rotary drilling rig to the High Speed 2 (HS2) project in London. Instead of a diesel engine, the BAUER eBG33 has a powerful electric drive. Thanks to a dedicated on-site sub-station, Cementation Skanska can operate the machine with zero local emissions.

This innovative rig proves that heavy-duty, electrically powered construction equipment can perform the same tasks as conventional equipment and is a further step towards diesel-free construction sites in the future. The eBG 33 has been operational for almost 500 hours on this project which means a considerable CO₂ saving. Additionally, the noise reductions are significant, with base carrier noise levels of 50% less, compared to a conventional rig.

Andrew Entwistle, Operations Director at Cementation Skanska, emphasizes: “The emission-free capability of this rig is an exciting step forward in our net zero ambitions. This type of innovation sits at the heart of our carbon reduction strategy and supports HS2 with its ambition for all its construction sites to be diesel free by 2029. Not only has it been valuable for us to work with the eBG 33 first hand on a live project, but it has provided an important opportunity to demonstrate the potential of all-electric heavy plant to the wider industry.”

Warren Arnold, General Manager of BAUER Equipment UK Ltd, says: “We are delighted to be working with Cementation on this project to deliver this world first use of a fully local emission free, high-capacity drilling rig. We are all incredibly proud of this unique rig which is setting standards. All the data recorded during operation will help Bauer in the further development of our environmentally friendly rigs and in our ambition to be the leading supplier of sustainable equipment for specialist foundation engineering. This really is a great opportunity to showcase what the eBG 33 can deliver in real terms and the benefits to the local community and environment.”

This deployment run is a continuation of work carried out as part of the HS2 project in Birmingham, where the rig was powered by a generator. There, the cable handling was tested for the very first time in a live environment. With the ability to connect the unit to the local power grid in London, Bauer and Cementation were able to put the eBG 33 through its paces and gather valuable data on power consumption throughout the piling operation. This data will be used in the further development of the battery-powered eBG 33 H all electric recently introduced by BAUER Maschinen GmbH.
