Our road construction team worked at Reutti from July to October.
Construction was carried out on the culvert at the Landgraben. In addition, the road surface was renewed over a distance of 3.4 kilometers. Before the new culvert could be installed, the land ditch had to be relocated and the groundwater level lowered. This was followed by the relocation of the stream, the backfilling of the old culvert, the construction of the ceiling as well as protective barrier and marking work.
The road was closed during this time and traffic was diverted.

|Work||Laying of a ductwork system, widening of the runway|
|Order value||EUR 14,000,000|
|Total value of construction project||EUR 22,000,000|
|Other details||EU tender|
TIME FOR THE NIGHT SHIFT
KUTTER beats off EU-wide competition
From a military airport to one of the most important backbones of the Free State of Bavaria: Allgäu Airport in Memmingen has been an important hub for some time now. It offers flights to Egypt, Corsica, Italy, Morocco, Spain, Portugal, Great Britain and many more destinations. With a new record flight plan of over 50 destinations, it is attracting increasing numbers of holidaymakers and business travellers. In order to be able to offer additional, varied destinations to its many air passengers in future, the airport is now being expanded – not least so it can continue to fulfil the increasingly strict international security guidelines.
After a ten-month marathon of negotiations, this challenging and exciting project was awarded to KUTTER. The costing work alone for this EU-wide tender took almost two months. This was followed by a lengthy planning process with regard to employee self-monitoring as well as a time-consuming approval process for each individual worker and each individual machine – after all, the project was for an airport, classed therefore as a high-security zone. Ultimately, KUTTER was able to complete the tender stage to the utmost satisfaction of the customer and emerged successful in face of the competitors from across the EU. Last November, the groundbreaking ceremony for the renovation project took place in the presence of Bavarian Minister President Markus Söder.
The excavators roll onto site at 9.30pm
Since March 2019, it’s been a daily occurrence for the KUTTER team: “Time for the night shift!”. As soon as the last flights have left the runway, the large construction machines start moving. First of all, cable trenches for a ductwork system were dug out along the entire runway, in which the electrics for the runway lighting will be installed at a later point. The biggest challenge: By 6am precisely when the first planes start moving, all the machinery must be returned the garage, and all the holes and trenches must be filled in until the four KUTTER crews get back to work again in the evening at 9.30pm.
Complete closure of the airport in autumn
Things will get really exciting in early autumn, when the airport will be completely closed to air traffic for the last two weeks of September. This is when the work will ramp up and be performed day and night in shifts to extend the width of the runway from 30 to 45 metres across its entire length. It will be a race against time as no delays can be afforded, considering the fact that the largest airline Ryanair will suspend all air traffic during this period.
Financed by the free state
The mammoth project is being partially financed by the Free State of Bavaria as well as the airport’s shareholders. The order value of the civil engineering work performed by KUTTER alone equates to EUR 15 million. To get an overview of the large construction project, Bavarian State Minister for Construction and Transport, Dr Hans Reichert, recently visited the site. Together with the airport’s CEO, Ralf Schmid, and Member of Bavarian State Parliament, Klaus Holetschek, KUTTER CEO, Peter Groll, and Head of Division, Andreas Binder visited the site with the politician, explaining the individual work steps and highlighting the particular challenges for both the workers and the machinery.
KUTTER in the media
Naturally, the project is being covered by the media. The press reports regularly on the progress, as do TV channels such as Allgäu-TV, which is often on site and broadcasts impressive footage of what is currently happening on the construction site.
The renovation works are scheduled to be completed in 2020. Besides expanding the runway and replacing the instrument landing system, the luggage halls are also being extended, the apron areas are being widened and a rainwater retention basin is being built.
KUTTER is proud to play a leading role in shaping such an important, regional project and wishes all of the employees involved every success!

LATEST PROJECTS: MILLING
NO MORE ROLLING AWAY
SHOPPING TROLLEY RETENTION SYSTEM
|Total length||approx. 900 m|
|Width approx.||5 cm|
The solution to a very common problem
Shopping trolleys rolling away in one supermarket car park in Vilshofen is a thing of the past. Using our special cutting machinery, we milled a profile into the asphalt in order to create a shopping trolley retention system measuring approximately 900 metres long. This was a really simple solution to a problem that we are all familiar with. The rear wheel of the shopping trolley fits neatly into the recess that is approximately 5 cm, holding the shopping trolley in place.
We mostly worked at night to prevent any disruption to ongoing operations.
HALL MILLING WORK
Special solution for indoor milling
Dust-free and low-vibration milling indoors – we are the specialists. Our video shows exactly how we create cable ducting or profiles in a closed hall.
We filmed the work performed at our customer PRÜM-Türenwerk GmbH in Weinsheim. All the measures were discussed in advance with the customer and adapted precisely to their needs. This enabled us, for instance, to work in halls that still contained warehouse goods, as no dust emissions were created.
Milling work in building structures: fast, clean, precise and cost-effective with KUTTER.
MOBILE COLD MIXING PLANT
A MOBILE PLANT
Independent and versatile
A mobile plant that replaces lorry journeys between the mixing plant and remote construction sites: KUTTER’s mobile cold mixing plant. Thanks to the separate diesel motor, it can operate independently of the public power supply. The cold mix that is created is suitable for a wide range of different construction projects: motorways, high-quality bearing layers for road and path construction, reinforcement of car parks and parking areas. Watch the video to learn out the diverse applications.
IN THE BLACK FOREST
A uniform substrate
Uniform and sufficiently load-bearing substrates are the prerequisite for the permanent and damage-free foundation of structures. In the event that the in-situ ground does not have these properties, it can be prepared so that it can be built upon and bear loads, by incorporating limestone and/or cement.
KUTTER carries out a wide range of ground improvement and ground hardening activities, such as in the construction of roads, car parks, industrial premises, airports and rail tracks. We can perform diverse earthwork, such as the creation of dams, embankments or backfilling. The soil stabilisers are also ideal for creating seals in landfill construction.
Thanks to this fast and environmentally friendly procedure, there is no need for time-consuming and costly replacement of soil.
RENOVATION OF A COUNTRY ROAD IN RADEGAST
Ecological and economical
As many roads in Germany are severely damaged several layers deep, for some time now it has no longer been possible to just replace the surface over and over again. KUTTER are the specialists for the job: we repair the entire structure of the road and permanently increase its load-bearing capacity. KUTTER are pioneers of cold recycling, and we have devoted ourselves to this ecological and economical procedure. The technological leadership acquired in this complex area enables us to maintain the functional properties of roads in the long term.
We renovate traffic areas with as little logistical effort as possible. And we do this with asphalt recycling. Our video shows you exactly how it works and what machines are used.
Green light for the airport
|Construction period||04/2021 - 05/2021|
|Material||350,000 m² concrete/hydraulically bound mixture|
Renovation of the runway in Leipzig/Halle
The large project to renovate the northern runway at Leipzig airport started with the deployment of a special construction milling machine.
The work included building 9,375 metres of rain run-off channels, among other things. The ideal machine for this is the special construction milling machine from Kutter Leipzig with side-mounted milling drum. The milled material was extracted using suction excavators and disposed of professionally.
Over the next few days, another form of milling was used. This milling work was recently carried out in collaboration with Wirtgen and our workshop at the Leipzig branch.
In addition, ten W250 large milling machines were used to mill a total area of 307,000 m² of concrete and hydraulically bound mixture.
This equates to a total volume of 350,000 tonnes, or the equivalent of around 12,400 loaded semi-trailer tippers!
Bridge demolition on the B37
|Construction period||05/2020 - 07/2020|
|Total surface area||10,000 m²|
|Milling machine used||radio-controlled W 50 milling machine|
The overall process
After noticing the damage on the bridge, the City of Ludwigshafen closed the bridge and surrounding area to all forms of traffic.
As this is a traffic intersection, it caused major disruption for the entire population.
In order to remove the partly contaminated coating without having to dispose of the entire demolition material, a radio-controlled milling machine with a maximum weight of ten tonnes needed to be used.
Up until this point, our company did not have a radio-controlled milling machine, therefore within a very short time, the milling specialists at KUTTER developed a W 50 milling machine offering all the required functions, which were converted to radio control.
Special feature: The machine operator remained on a part of the bridge that was not being worked upon and was held secure by a safety harness on a truck-mounted crane, from where they could operate the machine via remote radio controls.
The material was placed down on the bridge deck and picked up separately during the demolition work.
CONSTRUCTION OF A NEW BYPASS
Project Adelsdorf bypass
KUTTER is working on the construction of a new bypass in Adelsdorf. During the initial phase, 3,500 cubic metres of limestone were removed using heavy equipment (see images).
The asphalt junction at the existing traffic lane is currently being milled. Over the coming weeks, a further 1,100 cubic metres of rock will be milled for the second section of the bypass.
IN BERLIN MITTE
|Construction period||11/2019 - 11/2019|
|Total area||10,000 m²|
|Milled area||7,500 m²|
|Milled depth||0-12 cm|
|Material||concrete without reinforcement|
|Controller||Trimble tachymeter controller|
|Milling machine used||Wirtgen W 100 CFi|
MILLIMETRE PRECISION WORK IN BERLIN MITTE
In November 2019, the milling specialists at KUTTER GmbH & Co. KG milled the challenging profile of a drainage channel into a concrete surface.
A 3D system was used for the levelling work. Special feature: The project was for the Senate Administration for the Environment, Urban Mobility, and Climate Action on Karl-Marx-Allee in the heart of Berlin, under which runs an underground train line. For this reason, it was not possible to use large milling machines. Instead, KUTTER performed the 3D milling using a compact device with 1 m milling width, and developed an innovative solution that can safely discharge rainwater.
Work to redesign Karl-Marx-Allee, an avenue in the heart of Berlin measuring up to 72.5 m wide in parts, has been ongoing in several stages since the summer of 2018. In future, there will be less room for cars. Instead there will be wider cycle paths as well as attractive walking paths and open spaces. After removing the bituminous road surfaces, the drainage points and the pavement were replaced.
Drainage channel in the concrete surface
The next step – to create a profile in the concrete surface beneath the asphalt – was challenging from a construction point of view. The profile of a drainage channel was required in order to later ensure the drainage of rainwater along a length of approx. 800 m and a width of 5.75 m. The plans stipulated that the slope had to vary between 2.5% and 3% at distances of 3-5 m. On the remaining 9.25 m width of the road, the profile needed to have a cross slope of 2.5% from the centre to the edge of the road. Based on this geometry, this resulted in a milled depth that constantly varied between 0 and 12 cm. But what’s more, the Berlin underground railway runs beneath parts of Karl-Marx-Allee. Therefore, due to load restrictions, large milling machines could not be used on around 75% of the construction area.
3D milling with a compact machine
In light of this task, the team of milling specialists at KUTTER developed a concept together with the main contractor Matthäi GmbH & Co. KG for the precise profiling of concrete. The machine of choice was a compact milling machine with a 1 m milling width, equipped with a 3D levelling system. This is rather unusual as normally only large machines with a milling width of at least 2 m are used for 3D milling.
Tried and tested for many years
“For almost a decade, we’ve been successfully creating new profiles by means of 3D levelling and have tried out different systems. The variants
incorporating a Totalstation have proven to be the best for a wide range of tasks. Therefore, we were certain this method would be successful for the project in Berlin Mitte,” explains Roland Schmid, Head of Milling at KUTTER in Memmingen. This meant that the milling specialists were able to confidently deliver the required precision of ± 5 mm in accordance with additional technical terms of contract, and create the best conditions for laying the asphalt top structure.
|Project||Oberau tunnel bypass|
LIGHT AT THE END OF THE TUNNEL
The overall process
Swiss company Marti AG was awarded the contract to build Oberau tunnel.
The tunnel is essentially constructed using underground excavation with blasting. Once the rough removal of the tunnel cross-section was complete, our specially adapted mining milling machines were deployed to profile the tunnel invert to the exact height level required.
Our machine operators were guided by defined survey points and transferred the data by means of a laser controller which engages directly with the machine controller.
The milled material is loaded directly onto the transport vehicle on site via the integrated loading conveyor. The steep belt conveyors are reinforced with solid steel inserts to prevent damage caused by sharp-edged stone.
Our machines and their performance capacity
The performance capacity of our machines is generally based on the type of stone. This project involved dolomite stone and limestone with associated single-axial compressive strength values.
A further indicator for performance capacity is the fissurisation of the material to be removed, which can be naturally inherent or due to damage caused by stone blasting.
The special task
Another key area of this project was the creation of utility trenches within the tunnel invert. To complete this special task, we used the W 2200 milling machine with lateral milling device, which we had modified in-house and has a milling width of around 65 cm. This way we were able to create trenches that were approximately 70 cm deep.
The benefit of this technique is the fact that the milling machine with an entire operational weight of more than 40 tonnes is positioned centrally above the milling drum.
Quality thanks to years of experience
We have many years of experience in both surface and profile milling and can produce cost-effective results through optimised applications, even in extreme conditions.
The tunnel builders in Central Europe are familiar with the opportunities presented by milling technology, and are already incorporating our technology in the planning and costing phases of their projects.
Two weeks ago we were guests at the school festival of the Lindenschule Memmingen. As part of the programme, the students and their parents had the opportunity to take part in various tasks and stations. Various companies were also represented and the students were able to demonstrate their manual dexterity.
It was a successful school festival and if we have aroused your interest in the construction industry, then we are happy to welcome you, during an internship for example.

Company contact fair
KUTTER on the Pyramid
We were very pleased about the numerous visits to our booth at the Pyramid careers fair in Augsburg.
The trade fair visitors were not only able to find out about the best way to start a career, but also about student assignments as interns or working students and the different possibilities for the bachelor thesis.
We had many great conversations and are also pleased that you are visiting our careers section here on the website. There you will find all further information on the subject of studies and careers at KUTTER.
NEW CONSTRUCTION OF A
PENNY MARKET IN OFFENSTETTEN
On May 10, 2023, KUTTER invited to the groundbreaking ceremony for the long-awaited Penny market in the Offenstetten district of Abensberg. For the citizens of Offenstetten, a long-standing wish has come true with the construction of their own supermarket. The project is now possible not least because with KUTTER not only a construction company has been found, but also an investor for the building, because KUTTER will rent the building and the area to Penny Markt GmbH in the future.
Construction work began in October 2022 with the creation of the left-turn lane into the future supermarket site, with opening scheduled for early 2024. A Penny supermarket will be built with around 1000 m2 of retail space and 75 planned parking spaces. Environmental considerations were also taken into account, for example a green roof is planned. Heat pumps and recovery from commercial refrigeration are to provide the energy supply. A PV system is also planned for the roof. The location at the entrance to the town is also ideal, where there is already a restaurant, a bakery and a gas station with a car dealership. "People who shop locally avoid unnecessary traffic," Managing Director Ulrich Dick put it in a nutshell. In his greeting, he also emphasized the good cooperation with the Abensberg city administration, that the project could be advanced very quickly.

VHK Career forum
KUTTER meets students
at munich university
Yesterday we were at the Munich University of Applied Sciences at the career fair VHK Career Forum BAU!
More than 300 students from the construction industry from various universities from all over Bavaria and Baden-Württemberg were on site and were able to find out about the best way to start a career. Demand was also high on the subject of student assignments as interns or working students and the various options for the bachelor’s thesis.
We had many great conversations and are happy about the lively interest in KUTTER.
KUTTER Instructor Day
Coaching for trainers
in the conference hotel
In March, the trainers of all training professions from KUTTER go to a trainers' day in the conference hotel.
The priority was the exchange of experiences and the promotion of independent professional action in order to make our trainees fit for everyday working life.
The coaching focused on what it takes to successfully design the training for our trainees and what communication channels are needed.
The participants obviously had fun and we are sure that the common sense of togetherness was strengthened.
A few weeks ago we were able to welcome classes 7a and 7bM from the Türkheim middle school to our training workshop in Mindelheim for the construction rally.
The students had the opportunity to get to know the activities of our apprenticeships within the KUTTER Group at individual stations and to demonstrate their manual skills.
As part of this construction rally, the classes worked together to produce benches for their schoolyard. We were now able to hand over these benches and wish the students many nice breaks on them!
Attention: you can do an internship at KUTTER and RIEBEL all over the year. Just find out more at www.kutter.de/karriere or www.riebel-bau.de/karriere .
