We have just ended another month of works on the construction of the tram route to Mistrzejowice. In January, we focused on the construction of the “Polsadu Roundabout” station and the rebuilding of the Sudół Dominikański watercourse. What else have we accomplished?

On January 4 and 18, a Construction Council session was held. It was attended by representatives of the Private Partner and Local Government Entities, including the District Councils of Districts III Prądnik Czerwony and XV Mistrzejowice. Residents also showed up.  

Pending their evaluation and approval, in early January, we presented residents with documentation showing the temporary traffic organization (stage 2.3). However, please remember the design is not yet final. It is currently subject to the opinion of ZDMK, ZTP, MPK and the Police and the approval of the City Traffic Engineer. More

Responding to notifications and the needs of drivers, as of 11 January we have modified the current temporary traffic organization. These changes covered a section of Lublańska Street and Bora-Komorowskiego Avenue. More

In mid-January, we received from the Office of the City of Kraków a decision to modify the scope of Change Order no. 4. We could therefore return to implementing the project in the area of Lublańska Street: in accordance with the ZRID decision issued. More

In the second half of the month, we began embedding the first prefabricated elements for the construction of the Sudół Dominikański watercourse. The new canal will be about 400 meters long and will consist of 191 reinforced concrete prefabricated elements.  Read more

What’s up in February?

Since the beginning of February, our Information Center has been operating longer. On Mondays we are open from 8 a.m. to 6 p.m. and on other weekdays from 8 a.m. to 5 p.m. You are welcome! More

At the end of February we plan to introduce temporary traffic organization – stage 2.3. On Lublańska Street traffic between Polsadu Roundabout and Barei Roundbaout will be on the western carriageway only: where one traffic lane will be designated for each direction. In addition, vehicle traffic from and to Bora-Komorowskiego Avenue will be redirected to the temporary intersection with Lublańska Street at the height of the exit from Promienistych Street. More

In terms of tunnel construction works, we will continue building the “Polsadu Roundabout” station and begin mobilization of a new bentonite station for geotechnical work at the Młyńskie Roundabout. Additional slurry wall deepening equipment will soon arrive there. We will continue to work on the construction of more technology platforms. We will also begin work under the Iżyckiego Flyover. 

We will also continue working on the new channel of the Sudół Dominikański and reconstructing underground networks.

The tram route to Mistrzejowice is much more than just laying tracks between the existing terminus in Mistrzejowice and the intersection of Mogilska and Jana Pawła II Streets. It also involves the redevelopment of as much as 335 kilometers of existing infrastructure.

Redeveloping underground infrastructure in a large city is a complex process that requires efforts by many specialists. In the northern part of Kraków, it includes upgrades to the water, heating, sewage, gas, electricity and teletechnical networks as well as the redevelopment of the Sudół Dominikański watercourse. Their total length is as much as 335 kilometers. The redevelopment is necessary to provide residents with access to safe and sustainable infrastructure.  

Types of networks to be rebuilt: 

Water supply networks – 5.23 kilometers, 

District heating networks – 1.02 kilometers, 

Sewerage networks – 9.41 kilometers, 

Gas networks – 2.92 kilometers, 

Sudół Dominikański – 0.39 kilometers. It is an underground river which we described here,

Electricity networks – 45.54 kilometers, 

Telecommunications networks – 270.56 kilometers. 

Redeveloping underground infrastructure is a complex process that requires precise planning and coordination of activities. The work is carried out with the highest safety standards and takes place in stages. Once a new element is completed (for example, a trunk pipe made of ductile iron), the old infrastructure is repiped and then dismantled. Currently, the focus is on creating new underground infrastructure. The repiping is planned for the off-season. 

Underground networks are mainly placed under sidewalks, bike paths and in green belts. This allows easy access to installations during repair or maintenance work. In the case of repairs, this does not require disturbing the road surface, which minimizes disruption to traffic.

The KST IV Information Center is for the residents. That’s why, starting 5 February it will be open on Mondays from 8 a.m. to 6 p.m. and from 8 a.m. to 5 p.m. on other weekdays. You are welcome!

The Information Center is near the intersection of Dobrego Pasterza and Strzelców Streets. It is the immediate vicinity of our site office and almost halfway along the tram route under construction. Residents will find here detailed information about the course of the investment, including construction technology, work schedule, progress and current traffic organization.

Residents can contact the center by email at: info@tramwajdomistrzejowic.pl and by phone: 722 22 00 88 (Monday through Friday from 8:00 am to 4:00 pm).

See you there!

Building a tunnel involves adapting the area to new transportation needs. In the case of the Tramway to Mistrzejowice, one of the biggest challenges is the reconstruction of the Sudół Dominikański. It involves modifying the shape and course of the river and adapting it to the new development. 

The existing section of the Sudół Dominikański watercourse will be demolished: from the Młyńska Street/Macieja Miechowity Street intersection to the connection with the canal running from the Młyńskie Roundabout to the Prądnik River. The tram tunnel will be built in the footprint of the old segment. Water will be routed under the western roadway of Młyńska Street, parallel to the decommissioned route. The length of the reconstructed canal will be 388.65 meters (or about 400 meters including chambers).

Another important aspect is the appropriate selection of construction materials and implementation technology. The aim is to ensure durability and watertightness and to support works made in urban conditions in accordance with the schedule. The new canal consists of 191 reinforced concrete precast elements with internal dimensions of 3.00 x 2.25 x 2 m. Each one weighs 10.8 tons: that’s as much as 200 capybaras! Each element is embedded in a specially prepared excavation, protected in advance by a casing made of Larsen watertight sheet piling in the light of the new channel. It is then precisely assembled into the remaining segments.  

At the end of last week we began embedding the first prefabricated elements and have already completed 24 meters of the new canal!

A Larsen sheet piling is a steel structure used in geotechnical engineering to stabilize slopes, embankments or excavations.

In reference to the works made under the decision of the City of Kraków on the modification of Change Order no. 4, the following is the Contractor’s position on their progress.

Yesterday we continued cutting down trees and bushes on the western side of Lublańska Street: between the Barei Roundabout and the Polsadu Roundabout. The works were made by the kindergarten.

Trees and shrubs with insignificant girths there are unevenly bushy. They have heavily overgrown and tangled crowns. Some of the tree branches go over the kindergarten fence and lean towards the kindergarten area.

We worked under constant supervision of our managers and in full compliance with health and safety rules. The site was fenced off from public access. We were also in constant contact with the headmistress of the kindergarten.

As I mentioned, a branch of the tree located at the height of the end of the last span (the very corner of the kindergarten area) at the south side of the fence was directly over the fence.

Our employees lowered this branch to the fence in a controlled manner, and then manually placed it over the fence. There were no children in the vicinity, and our staff watched over the entire technological process of felling.

The entire fence of the kindergarten running along Lublańska Street (parallel to it) is scheduled for dismantling, so there is no question of harm to third parties here. At present, the fence is still performing its function. It is tight and has not been damaged. We will notify the management of the kindergarten about its removal with due notice.
