STORAGE HALL Juta a.s. – Dvůr Králové nad Labem

03/2025

Here we are again – in Dvůr Králové nad Labem, in the Juta a.s. complex.

We are drilling piles under the storage hall (SO38) and we are also going to execute a permanent pile wall, which will be used not only as a retaining wall, but will also work as a foundation for a few of the columns of the new hall. According to the project, the piles under the building (system piles) have a diameter of 750 and 900 mm, the pile wall will be made of piles with a diameter of 1000 mm. The wall will be coupled with a reinforced concrete beam at the top and anchored through the beam with permanent rope anchors towards the building. When preparing the project, it was necessary to pay great attention to ensuring that the designed anchors do not collide with the newly drilled system piles.

The construction is led by Vladimír Slavíček, the project was prepared by Ing. Ondřej Tušl.

PIPE BRIDGE – Kosmonosy

03/2025

A mole was rampaging in Kosmonosy! And it was very powerful – it was able to drill through the concrete floor of the hall! :))

Our smallest drill was given the task of drilling micropiles to anchor the pipe bridge inside the hall in Kosmonosy. For the foundation, it was necessary to execute core drilling through the existing floor and make micropiles with reinforcement according to the project (steel pipes 89/8 and 89/12.5).

The construction is managed by Jan Chadima, the project was prepared by Ing. Vojtěch Ježek.

AB LEOPOLDOVA Prague

02/2025

The BG20H drilling machine is currently drilling the Berliner wall for a new apartment building in Leopoldova Street in Prague. The wall will consist of double 2xIPE360 profiles, which will be anchored in two levels through the aforementioned pairs of steel soldier piles. The piles are designed to be 11.50 and 12.00 m long and will be made of S275 steel. The anchoring will be carried out with 4 or 5 strand anchors. The maximum length of the anchors will reach 15 m.

Our work delivery also includes system piles under the building, which will have diameters of 620, 900 and 1200 mm. In addition to the above, we will also execute piles for a crane.

The construction is managed by Petr Malý, the project was prepared by Ing. Jan Mrázek.

VALALIKY INDUSTRIAL PARK – 2nd PHASE Košice (SK)

01/2025

In Košice, we have already drilled more than 1650 piles! And now we are doing, as we say – saving the best for last. Now in Košice, piles with square caps are being implemented, which are some of the most difficult of foundation works. From project preparation, production in the reinforcement shop, excavation the pit and Berliner wall execution, to the actual installation of the cap reinforcement in the prepared pit and the concreting itself. In the photo below, you can see how large the reinforcement is compared to a human figure.

The largest cap was designed to anchor three columns (=>three cups in the cap) and measures 2.95×4.20 m with a height of 2.30 m.

The construction is led by Miroslav Slabý and Šimon Koritenský and the project is being prepared by Ing. Ondřej Tušl.

POLYFUNCTIONAL HOUSE ANGLICKÉ NÁBŘEŽÍ – U ZVONU  Pilsen

12/2024

You can currently find us in Pilsen, where the construction of the new Polyfunctional House between Anglické nábřeží and U Zvonu streets has recently begun. Two underground floors are designed for the new building under most of the floor plan, and one is designed for the northwestern part. Our contractor work includes the preparation of the project and the execution of temporary retaining structures of the construction pit, including the design and execution of piles. At the same time, we also had to design the retaining structure for the neighboring building (BCB) during the demolition of the existing building on the site of the planned polyfunctional house.

The entire design of retaining structures is very complex and comprehensive due to the abundantly endowed aquifer in the Quaternary cover (the Radbuza River in close proximity). In order to seal the construction pit, Ing. Ondřej Tušl used his knowledge of the trench cutting and remixing deep (TRD) technology when designing the sheeting. This technology, based on the principle of deep soil improvement, will create a barrier to groundwater flow. The proposed technology is combined with an anchored Berliner wall. In the place where it is not possible to execute TRD for spatial reasons, and also near the existing building (BCB), a secant pile wall was designed. System piles in the perimeter of the construction pit will be drilled together with the retaining structures. The total length of the boreholes will reach up to 20 m because of the “blind drilling".

You can see here just several photos from the beginning of the construction. We will gradually inform you about the progress of the construction and add more photos.

The construction is led by Ing. Radek Vlasák, the project is in charge of Ing. Ondřej Tušl.

VALALIKY INDUSTRIAL PARK – 2nd PHASE Košice (SK)

11/2024

At the moment, there is only one drilling machine (BG 23H) on the construction site, which has the task of completing all the work on the pile foundation of Phase 1 and Phase 2. In total, it is about 100 piles, diameter from 750mm to 1300mm, on approximately 5 buildings ( SO120, SO140, SO150, SO160, SO170). The crew works alternately in the Czech Republic and in Košice – the workload depends on the delivery of documents by the client; after receiving the documents, our designers will immediately prepare a project incorporating changes and revisions, and work on the construction site will then continue.

The SO 160 building, realized as a part of Phase 2, was one of the most difficult constructions in the whole Valaliky industrial park and it has been possibly also the most difficult construction in the history of our company – thanks to the specific geology found in-situ. On more than a half of the construction area of the SO 160, the piles ended in layers of gravel and sand, which were full of highly pressurized water. The water pressure was such that it was able to push the water even through the concrete in the piles to the ground. From the very beginning of work on Phase 2, we have been trying to solve this problem with the concrete supplier, its technologist, and subsequently with the leading experts in concrete technology in the Czech Republic, including prof. Rudolf Hela from VÚT Brno. Prof. Hela was the one, who helped us the most to solve the problem by significantly modifying the concrete formula.

The prepared plain also caused great difficulties – very suitable in terms of load-bearing capacity, but considerably unstable in terms of drilling – mainly in terms of maintaining the external dimensions of the pile caps and work safety during the subsequent installation of the reinforcement of the caps.

Another problem was the very high horizontal forces from the superstructure, which generated the necessity of using massive reinforcement in the piles. The need to ensure the anchorage length of the pile reinforcement in the pile caps led to the design of a new system for connecting the pile and the cap.

Despite all the mentioned complications, we successfully completed the foundation works of the SO160 object last week.

The construction site is led by Miroslav Slabý, Petr Malý and Šimon Koritenský, the project is processed by Ing. Ondřej Tušl.

ADMINISTRATIVE BUILDING Praha-Radotín

10/2024

We are finishing the special foundation works for the new administrative building in Radotín. We have drilled 30 piles for the foundation of the building and 21 steel soldier piles yet. Excavation of the construction pit and the installation of wooden lagging between the soldier piles are now underway.

The construction is led by Vladimír Slavíček, the project was prepared by Ing. Jan Mrazek.

GL PARK Pardubice

09/2024

Our second drilling machine BG20H is currently working in Pardubice, in the historical Semtín-Rybitví industrial zone. This area was originally focused on chemical production. Here we drill 620 mm diameter piles with 1250 mm diameter circular caps. The upperstructure will be constructed of prefab concrete columns, therefore the caps are equipped with cups for bearing these columns.

The geological subsoil of the site consists of layers of sand and gravel (Quaternary sediments of fluvial origin), which alternate with each other. The total thickness of these sediments ranges from 7.50-9.50 m. Below them, there is a chalk bed formed by marlstone. A high groundwater level is also typical for this area, the water level is 1.35-1.60 m below the existing terrain. When drilling piles, we use casing and the piles are designed to end in marlstone.

The speciality of this building site is also the high aggressiveness of the groundwater (classified as XA3 according to ČSN EN 206-1), thanks to the high content of SO4 sulfates and the exceptional and extreme value of CO2. Therefore, we use C30/37 XA3(SO4) concrete for piling.

Ing. Jan Mrázek prepared the design, Ing. Radek Vlasák is managing the construction site.

PANATTONI PARK Chomutov-Jirkov

09/2024

We are currently finishing the foundation of a new hall for HOPI CZ in Panattoni Park in Chomutov. This is the second big project we are working on in this location, so we were able to use our knowledge of the subsoil at this location. Our BG20H drill and borrowed Soilmec are drilling on the construction site. Drilling takes place through clayey layers without the need of casing.

We are drilling piles with a diameter of 900 mm, 239 pcs in total. The maximum drilling length is 15 m. The piles are equipped with circular caps with a diameter of 1350 mm with cups for prefa columns. The two caps were made square shaped.

The project was prepared by Bc. Ondřej Krkavec, construction is led by Vladimír Slavíček.

VALALIKY INDUSTRIAL PARK – 2nd PHASE Košice (SK)

08/2024

The second phase of construction works in Košice has already started, we are currently executing deep foundation for object SO160. It is planned to drill approximately 490 piles with diameters of 1000, 1300 and 1500 mm with pile caps for prefa columns. The start of drilling is greatly complicated by the geological substratum, specifically the pressurized water at about 12 m under the ground causes problems. The water has already risen above the ground level in several piles. Thanks to many years of experience, we can deal with this situation well, so we are not late and we can keep going.

Our largest drilling machine BG28H and also BG23 are currently working on the construction site.

The construction is led by Miroslav Slabý, Petr Malý and Šimon Koritenský, the project is processed by Ing. Ondřej Tušl.

OBROBNA RESL PRODUCTION HALL EXTENSION Liberec

07/2024

We have already finished an extension of the modern production hall for the expert in CNC machining – Obrobna Resl s.r.o. – in the industrial zone of Liberec-North. A total of 31 piles, mostly with circular caps, were drilled by our BG 20H drill.

Drilling proceeded without any problem, one pile diameter of 900 mm was used. The diameters of the circular caps were chosen, as usual, according to the specified dimensions of the prefabricated columns. Caps with a diameter of 1250 and 1350 mm were drilled on this construction site. Square caps were made for pairs of columns.

The project was prepared by Ing. Vojtěch Ježek, construction site was led by Petr Malý.

SHIMANO CZ Karviná

06/2024

Our drilling machines have moved from Košice to Karviná, to the premises of Shimano Czech Republic, s.r.o., where we already know it well, as it is not our first time there. The subject of our works is the design of execution documentation and subsequently the implementation of deep foundations for new halls, that will extend the company's production plant. This is already the 4th phase of the extension, and the work is currently underway to found halls SO401 and SO402 (new production hall and administrative building). The 5th phase of extension is also planned for the future.

At the construction site, the subsoil is formed by dumped soil in the top layer, under which alluvial clays were found. Sands and gravels occur under that clays and act as a collector – an environment in which groundwater is accumulated. Under the gravels the plastic clays were found. According to the composition of the soil profile, it is clear that the drilling of the piles will be done with casing and the concreting mostly with the pipes.

We are now drilling piles in SO401. Piles have diameters of 750, 1000 and 1200 mm and lengths of 5.0 – 15.0 m, which will be equipped with round or square caps with cups for prefa columns. In the object SO402, piles with a diameter of 750 and 1000 mm and lengths of 6.0 – 13.0 m and round heads await us.

The documentation was prepared by Bc. Ondřej Krkavec, construction is managed by Miroslav Slabý.

VALALIKY INDUSTRIAL PARK Košice (SK)

06/2024

First phase done! Our drills have already left the construction site in Košice, and in the first days of June, only finishing work on ​​the piles inside the pits in the SO110 building was taking place.
The piles inside the pits were drilled with a 6 m long blind drilling (the final head of the pile is located 6 m below the original terrain – at the bottom of the pit). Due to the high level of the underground water, it was necessary to pump water non-stop from the construction pit during the excavation work.

In the photos, you can see the piles before the final treatment of their heads, as well as the pit with already finished base concrete.

Our machines will return to the construction site in Košice in about a month to start the second phase. Ing. Ondřej Tušl is currently working on the project.

PKS OKNA a.s. Žďár nad Sázavou

05/2024

We have just completed the deep foundation of the extension of the PKS-Okna company hall in Žďár nad Sázavou. Piles with a diameter of 620 and 1000 mm were made, which are equipped with pile caps with a diameter of 1250 and 1350 mm. The pile caps were concreted above the ground, into a formwork prepared from the B-system. You can see the freshly concreted caps with cups for prefa columns in the attached photo.

The project was prepared by Ing. Ondřej Tušl, the construction site was managed by Ing. Radek Vlasák.

When it is necessary to expand an existing building, it is necessary to take into account that piles cannot be placed right next to the existing structures. Already during the preparation of the design project, the handling space (minimum distance from the obstacle), which the drilling rig needs, must be taken into account in order to avoid damages to the existing structure (building cladding, gutters, lights, etc.) when drilling piles. The minimum distance from the obstacle depends on the diameter of the drilled pile. For piles with a diameter of up to 900 mm, we consider a distance of 850 mm (to the center of the pile), for larger pile diameters use 1000 mm.

ANIMAL ADOPTION, Prague ZOO

05/2024

Our company Čeněk a Ježek a.s. regularly adopt animals from Prague ZOO to support this institution. We keep the tradition and we adopted 4 animals for year 2024.

The first choice was Short-beaked echidna (ježura australská), which is an animal similar to a hedgehod (= “Ježek" in our company name).
Since we executed a foundation for a new monkey pavilion, the Western Lowland Gorillas (gorila nížinná) was the second choice.
We have also chosen the cute Long-eared hedgehog and it immediately became a darling of the whole company.
The last animal chosen for 2024 was a beautiful small cat, which can be really dangerous – Pallas's cat, also known as Manul.

RETAINING STRUCTURES AND DEEP FOUNDATION Škrétova, Prague

04/2024

The April ended and we successfully finished all the works of the special foundation and retaining structures at the Škrétova building site, which we wrote about here already in February.

In the attached photos you can clearly see the slope of the black slate layers found at the bottom of the construction pit. The first photo shows the final appearance of the construction pit with the base concrete. This photo was taken by our brave construction manager Ing. Radek Vlasák from the crane.

TERMIZO a.s. Liberec

04/2024

Waste management is the topic of today. We were asked to execute deep foundations for a new air condenser for TERMIZO a.s. waste incinerator in Liberec, which uses mixed municipal waste and selected industrial waste as a fuel for the production of heat and electricity.
In the photo you can see our BG20H drilling machine in action, drilling piles with a diameter of 1000 mm. The piles have square heads, into which the anchoring of the steel structure of the condenser was inserted using chemical adhesive anchors.
The construction is led by Vladimír Slavíček, the project was prepared by Ing. Ondřej Tušl.

We wish you spring days full of new, fresh and positive energy and Happy Easter!

NEW PRODUCTION HALL PANASONIC CZ Pilsen

03/2024

Take a look at the photos from the construction of the Panasonic Plzeň HVAC hall, which we wrote about at the end of last year. The photos were taken at the end of February, when our machines were still drilling the piles. Now all the work on the foundation is finished, the drills have left the construction site and are continuing on other projects, which we will let you know about in the near future.

RETAINING STRUCTURES AND DEEP FOUNDATION Škrétova, Prague

02/2024

We are currently working on a retaining structures and deep foundations for the new RU-SH Apartments building, located not far from the National Museum in Prague, in Škrétova Street. The specialty of this project is that the building site is located in the backyard of the city apartment buildings. This fact brings many limitations. One of them is a narrow access to the construction site (through the entrace for a passenger car). Thanks to this limitation, it was already necessary in the project to count on the use of a small-diameter drilling rig, which is able to pass through the entrance to the backyard (you can see it in the first photo).

To secure the construction pit, soldier micropiles (steel HE140B) with drained shotcrete will be used, anchored in one or two levels, depending on the depth of the foundation pit.

Our delivery of works also includes design and execution of micropiles for strengthening the foundation of the existing apartment building, underlaying of neighboring buildings, including the use of tendors (nails), and the design and construction of the foundation for the crane (footing supported by 12 micropiles). The footing is already finished and the crane is already erected at the building site, as you can see in the attached photo.

Currently, all the soldier micropiles have been drilled, the first row of anchors is ready on 3/4 of the perimeter of the foundation pit, the neighboring buildings are underlayed and all micropiles are also ready. Shotcrete spraying and excavation of the construction pit are now in progress.

The construction is led by Ing. Radek Vlasák, the project was prepared by Ing. Vojtěch Ježek.

PERMANENT PILE WALL Dolní Beřkovice

02/2024

We informed you at the end of the last year, that it was necessary to design a structure to retain a slope on the bank of the Elbe river to build a wharf on the Elbe in Dolní Beřkovice.

We have already finished design and also the execution of the unanchored pile wall and you can see the structure in the photos below.

PRODUCTION HALL, WAREHOUSE AND SPRINKLER, TOPPAN PACKAGING CZECH Havraň

02/2024

We have just finished execution of deep foundation for a production hall, external warehouse and sprinkler for Toppan Packaging Czech in the Joseph industrial zone near Havraň. As a part of the project, we made over 170 piles with diameters of 750, 950 and 1000 mm. The piles are mainly designed with circular caps with cups for attaching the prefa columns of the upper structure. One pile cap was designed square shaped and was made in an excavation secured by soldier piles with lagging (bcs the lower edge of the pile cap is located at the -5.05 m level).

The project was prepared by Bc. Ondřej Krkavec, the construction was led by Ing. Radek Vlasák.

VALALIKY INDUSTRIAL PARK Košice (SK)

01/2024

We are reporting from windy Košice. The temperatures of the last few days have been slightly below zero, but thanks to the strong wind, we felt like it was -18 °C. When trying to insert the reinforcement cages into the bore holes, they act like flying feathers in the wind, so the work is extremely demanding. The fact, that the groundwater is located approx. 30 cm below the ground level and the geological profile is very variable does not improve the situation much. But our team does not give up and work tirelessly together with our designers to keep all commitments. Currently, three of our drilling machines are working on the construction site – BG28, BH23 and BG18.

The construction is led by Libor Dvorský and Miroslav Slabý together with our two new construction managers – Petr Malý and Šimon Koritenský.

Check out the photos from the site below. You can see the erection of the first column or a detail of the PEIKKO screws used to attach the prefa columns to the pile caps.

NEW PRODUCTION HALL PANASONIC CZ Pilsen

12/2023

Construction of a new HVAC (heating, ventilation, airconditioning) production hall has just started in Panasonic CZ area in Pilsen, Borská pole. It will grow on the site of the former hall, which was demolished and its foundations (footings) were removed.

We are very pleased to design and implement a deep foundation for this project. In total, we expect to make over 650 piles, mostly with drilled pile caps, while the longest piles will be 24 m long.

4 drilling rigs already work on the construction site and according to reports from the construction site, everything is going like clockwork. The subsoil consists of clayey sands, and one could say that there is a “drilling paradise". 😊

The project was prepared by Ing. Ondřej Tušl, construction is led by Vladimír Slavíček.

Christmas present – NEW BG23H

12/2023

Have you bought all your Christmas presents yet? We made ourselves happy with one really big gift – new drilling rig BG23H! 
It has already left to Košice to help its colleague BG28H with drilling.

PANATTONI PARK Cheb

12/2023

The large storage hall in the Panattoni Park complex in Cheb, the construction of which we participated in (construction started in November 2022), will be completed soon. See the attached photos of the really extensive structure.

We drilled a total of 963 piles, most of them with round caps with cups used for inserting the prefa columns. The largest diameter of the caps was 1800 mm and the longest piles measure 26 m and have a diameter of 1300 mm. Our works also included an implementation of retaining structures for excavation pit for the storm sewer and lift.

The construction site was led by Vladimír Slavíček, the project was prepared by Ing. Jan Mrázek and Ing. Ondřej Tušl.

Christmas party

11/2023

At the end of November, we received an invitation to a Christmas party from our friends from 3G Praha s.r.o. The session took place on the ship Hamburg on the Vltava river in Prague and its stylish dress-code was sailors/boaters.

We enjoyed a romantic night cruise through Prague, excellent food, a bottomless bar, nice service, but most of all a lot of fun and great company. It was, by the way, as always with 3G, a perfect party, and we look forward to the next meeting together, be it formal, work or informal.

VALALIKY INDUSTRIAL PARK Košice (SK)

11/2023

Our largest drilling machine BG28H with the entire crew, led by Miroslav Slabý, has already arrived in Košice and started working on the project we already wrote about in the summer.

First, the crew started drilling secant pile wall, which will retain the pits for the new technologies. In the first building, two pits will be realized and both will be made of piles with a diameter of 1000 mm and lengths of 7.50 m (primary piles) and 10.50 m (secondary, reinforced piles). 311 piles will be drilled in total. The retaining wall will be anchored in one anchoring level.

Before the start of drilling piles, guide walls were made to help the accuracy of drilling. You can see the construction of the guide walls in the attached photos.

Due to the expected geology (liquid sands in the interlayers of Neogene clays and pressurized water), the boreholes need to be steel-casted along their entire length and it is necessary to be in constant contact with the designers in case of unexpected changes in the geological profile.

The project manager is Ing. Vojtěch Ježek.

PERMANENT PILE WALL Dolní Beřkovice

11/2023

To build a wharf on the Elbe in Dolní Beřkovice, it was necessary to design a structure to retain a slope on the bank of the Elbe river. Ing. Jan Mrázek has already designed a permanent unanchored contiguous pile wall consisting of 24 piles with a diameter of 750 mm. The piles are connected in their heads by a reinforced concrete beam with a height of 800 mm. Due to the length of the pile wall, three dilatation joints were designed in the wall.

The piles has been already drilled. It will now be followed by the reinforcement and concreting of the beam at the pile heads. After that, the slope will be gradually excavated up to the designed level with the simultaneous implementation of reinforced and drained shotcrete between the piles.

The construction site is managed by Vladimír Slavíček.

VECTORPARKS Prešov (SK)

10/2023

On the way to Košice! We have just made a stop in Prešov to drill piles in the VectorParks Prešov logistics park. We are drilling deep foundations for the SO 101 warehouse-production hall and piles for a pile wall. The pile wall will be unanchored and made of piles with a diameter of 600 mm. The piles will be connected in their heads by a reinforced concrete beam and there will be also executed shotcrete with a thickness of 100 mm between the soldier piles.

The foundation and pile wall projects were prepared by the client, the building site is managed by Miroslav Slabý.

LK PUMPSERVICE Prague Letňany

10/2023

We have just finished works on deep foundations for a new warehouse for LK Pumpservice in Prague, Letňany district.
Our drilling rig BG18H executed 53 piles with a diameter of 750 and 1000 mm. Most of the piles were made with round caps, only a few of them were made with rectangular caps – they carry two columns in one cap.

Ing. Vojtěch Ježek designed the deep foundation, Vladimír Slavíček managed the construction site.

CTPark Blatnice

09/2023

We are drilling and drilling, right now in Blatnice, not far from Nýřany. The interesting fact of this location is that there are significant coal seams that were deepmined in the past and there are corridors in the underground left. In 2016, an expert opinion was carried out, which was subsequently used in the design of the piles that we are currently implementing here. Our BG20H drilling machine is drilling 199 piles with round caps for the assembled reinforced concrete skeleton of the new hall. Piles with a diameter of 750 mm are drilled with predrills for pile caps with a diameter of 1250, 1400 and 1600 mm. Already in the predrills of the caps, we have been reaching sandstone with a hardness of R4-R3.

The construction site is led by Ing. Radek Vlasák.

NEW DRILLING RIG

Our machinery fleet got bigger and stronger again! In order to be able to implement the deep foundations of extremely loaded structures, which generate large dimensions and lengths of piles, we purchased a new, powerful BG28H instead of the BG23H. This new drilling rig of ours can drill a pile with a diameter of up to 1500 mm (dia 1800 mm after a minor adjustment), and it can also drill large round pile caps (with a diameter of up to 2000 mm) without any problems.

VALALIKY INDUSTRIAL PARK Košice (SK)

07/2023

The summer holidays are in a full swing, everyone is on a trip, and so is our BG20H drilling machine. Right now you can find it in Košice, in the east of Slovakia, where it performs a very important task – it carries out technological drills and piles for load tests in the future large production area. But it is not easy at all, because the geological and hydrogeological conditions at the site of the future construction are extremely demanding. Drilling is complicated by liquid sands in the interlayers of Neogene clays. And to make matters worse, these are sands with pressurized water, which after drilling can rise up above the ground level in an instant and fill the entire borehole with fine sand. The exact positions of these sand layers are practically impossible to map in advance. Our drill crews will have to be very alert and skilled indeed! They will also have to be in contact with our designer, who will continuously update the project documentation according to the situation on the construction site. For more than a thousand piles…

Our designers, led by Ing. Vojtěch Ježek, have been working on the project from the very beginning. The results from the technological boreholes and load tests will be used for a more economical foundation design for the entire future factory. The start of the construction work is planned for November of this year. It will be a challenge, but we are ready to do precise work even in these extreme conditions.

HEATING PLANT Králové nad Labem

06/2023

We have already warmed up two times this year at the Heating plant area in Dvůr Králové nad Labem. The first time we drilled deep foundation of the boiler house (piles with circular caps for prefa columns), the second time we managed two projects at once – piles under the base plate for the storage tanks and the foundation of the energo bridge.

The attached photo shows the piles under the storage tanks.

G-TES EXTENSION Nitra (SK)

06/2023

We are returning back to Nitra, after 5 years, to help with an extension of the halls of G-TES, for which we drilled piles in 2018.

We are currently drilling piles and preparing the square pileheads for the prefab columns in the extension of the press shop. Due to the pile heads dimensions (1.45×2.00×1.80 m) and the local geology, it is necessary to retain the excavation pit. We always first make the soldier piles with lagging and then the excavation and the head themselves, as you can see in the attached photos. We are also drilling piles for an extension of the administration building and the welding shop extension.

The construction site is managed by Libor Dvorský, the project was prepared by Ing. Ondřej Tušl.

TEAMBUILDING Giant mountains

05/2023

We went to Giant mountains for our teambuilding. The weather was great, so that we could do some hikes along the ridges and enjoy the breathtaking views. We also spent some time in the spa, tasted excellent food and chatted with each other and with our friends from 3G Praha s.r.o., who visited us there. The days were full of laughter and joy and we are already looking forward to the next teambuilding.

LE & CO Jirny

05/2023

It looks like our drilling machine is already sulking in the corner and refusing to continue drilling anymore, but it is not the case. We came back to Jirny, to the LE & CO area, to drill another deep foundation for new shelters, corridors and a pedestrian bridge between the production halls (we drilled its foundation last year). Our drilling rig has to drill very close to the existing hall, because the pedestrian bridge will be built here. Piles dia 1300 mm are needed to carry the large loading from the upper structure (bridge).

The project was designed by Ing. Ondřej Tušl, construction is managed by Miroslav Kloc.
