What is being built?

Ybl students had a glimpse of Zugló's large-scale development

Published

The young people had the opportunity to spend a professional morning at the construction site of the new urban quarter built by Bayer Construct Zrt.

Our newspaper regularly reports on the area between Bosnyák Square and Rákos Creek, where the Bayer Construct Zrt.. Eight buildings – one residential and seven office buildings – will be constructed on the approximately seven-hectare site. Spacious communal areas and a pedestrian street will be created between them.

The civil engineering work for the large-scale investment project is being carried out by BAUER Hungary Special Civil Engineering Kft.. As previously reported, the complex's residential building reached structural completion in March 2023. The company completed the piling work for the facility, known as R1, in July 2022, followed by the civil engineering work for the office buildings named O1 and O2, project manager Dániel Hadnagy informed our newspaper.

The slitting and anchoring work took place in the autumn of 2022: nearly 800 anchors were completed in three rows. This included the temporary dewatering of the working pit, using temporary drainage wells and open water.

The pile foundation in the work area was also the responsibility of Bauer. This could be started after the pit was fully excavated. During the approximately one and a half months from the end of February to mid-April 2022, nearly 1,700 fm of CFA 600 working area piles and more than 4,600 CFA 800 structural piles were constructed.

The drainage of the working pits was carried out in a specific way

In the next phase, the company carried out the masonry work on office buildings 2, 3 and 4 and the drainage of the working pit, which was completed in May. The civil engineering works for the R1 residential building and the O1, O2 office buildings have already been completed. The anchoring of the buildings is now underway in phases O3 and O4.

The photos also show the machines BAUER has used in the various processes. One of the largest machines in the fleet is the MC76 type slitting machine, which is equipped with a service crane with a chain. The BG28as piling machine and the Klemm type anchor drilling machine were also essential for the professional execution of the tasks.

Dániel Hadnagy presented the special feature of the project as the dewatering of the working cavities of each office building. The four buildings (O1, O2, O3, O4) were demolished at different times, but as a whole as one big pit. For this reason, the slitting of working pit O1 was only completed as a closed working pit on 3 sides.

Dewatering the pit would have been futile without sealing off Side 4, so instead of a diaphragm wall, a demountable solution was used: a slurry wall was constructed around the middle of the O2 phase to connect it. This prevented groundwater ingress. This allowed the drainage of the working pit to be achieved, despite the fact that the slit wall was only completely enclosed this year.

The mysteries of civil engineering were also presented to Ybl students

BAUER also wanted to show young people the work being carried out on the Zugló City Centre project, so it organised a tour for students of the Ybl Miklós Ybl Faculty of Civil Engineering at Óbuda University.

"The aim of the guided tour was to bring the students a little closer to "our world" and if they are attracted to this part of the construction industry, we welcome them to our internship with open arms. For a university student, we think it's crucial to see everything from the ground up to the last tile being laid, and to get a little bit of a sense of the why. It's hard to know what they want to do within the profession, so a professional morning like this helps them a little bit to figure out what it is they want to look into in the first place"

- project coordinator Stella Berka told us.

The complexity of the project, in addition to the large volume, was the parallel workflows. The fast and accurate processing of construction data was of paramount importance. This was done using Bauer's innovative in-house developed software, BProject, which allowed us to easily manage and monitor all the technologies. In addition, its unique functionality, with reports and 3D models, helped back office colleagues to monitor processes efficiently.

The students also received on-site safety training from both the contractor Bayer Construct Zrt. and BAUER Hungary Kft.. Afterwards, foreman Tibor Olosz and project manager Dániel Hadnagy showed the group around the site. Most of the participants had only theoretical knowledge of civil engineering, so the presentation was met with great interest.

Fortunately, the favourable phase of the work allowed each stage of the fissuring work to be observed. In addition, they were also able to view the working pit, which had already been completed and was raised to the planned height. Of particular interest to the students was the presentation by the archaeological excavation manager of their work and achievements in the field.

The promotion of prefabrication was also an important aspect

Another part of the students' tour was the contractor's Bayer Construct Zrt. programme, in which Gergely Szalai, project manager, presented the project. In his presentation, he discussed the planning, timelines and targets.

The young people also had the opportunity to visit the then-ready R1 condominium building: they went through the different floors and were given information about one of the most important areas of the construction process, prefabrication. As we reported earlier, Bayer is speeding up the development and making it extremely efficient with prefabricated elements from its plant in Biharkeresztes. The project manager showed the integrated bark panel elements as well as cooling and heating panels.

In connection with the deep foundation works of the O1 office building, the students were informed about the process and system of structural engineering. Another key topic was organisation, as precise organisation is essential for efficient implementation, and the Bayer Group pays particular attention to this in all its projects.
