On Wednesday, the spokeswoman for the Warsaw branch of the General Directorate of Roads and Motorways, Małgorzata Tarnowska, announced that the acceptance of the ventilation system in both aisles of the Warsaw Southern Bypass tunnel was underway. In turn, firefighters announced that further fire tests will be carried out next week.
On Wednesday, in an interview with the Polish Press Agency, Tarnowska informed that the acceptance of the ventilation system in both aisles of the tunnel of the Warsaw Southern Bypass is underway. – There are 8 scenarios. Each of them has 86 fire zones. This means that there are 688 scenarios of the system operation to be verified – she calculated.
More firefighters trials next week
In turn, the spokesman of the Masovian State Fire Service, Karol Kierzkowski, said that technical approvals will begin at the beginning of next week. – The new tests will start on Monday, October 18, and we have until October 25 to carry out these inspections – emphasized the firefighter.
As reported last week by “Gazeta Stołeczna”, during the smoke tests, the ventilation in the POW tunnel did not work correctly. Therefore, the firefighters refused to accept the investment and announced another inspection. According to the sources of the journal, automatic smoke extraction did not work during the test. The fans were supposed to work, but only when they were manually turned on by employees of the supervision center, despite the fact that GDDKiA had previously announced that the tunnel would be equipped with several safety systems and automatic sensors.
After the acceptance is completed, the next step will be to submit an application to the Provincial Building Supervision Inspector in Warsaw for a decision on the use permit. As Tarnowska explained, WINB employees have to check the extensive as-built documentation, then carry out a field inspection and issue an occupancy permit. – The final stage of the acceptance process is the control of the Mazowieckie Voivode. After checking the security documentation and receiving the opinion of the security officer, it will grant permission to open the tunnel, she said.
As reported on tvnwarszawa.pl, the opening of the tunnel under Ursynów along the Southern Ring Road of Warsaw has been postponed many times. We wrote at the end of September with a faulty surface. It was about “lack of the required frost resistance” in the approximately 400-meter section, outside the tunnel. The contractor had to carry out repair work at his own expense.
Initially, the entire investment, consisting of three stages, was to be commissioned in August 2020. However, it was not until December, just before Christmas, that two sections were opened: from the Lubelska junction to Przyczółkowa. In the case of the tunnel near Ursynów, in accordance with the annex to the contract, the time for completion of works was extended until the end of March 2021. The reason was, among other things, a long procedure of obtaining a permit for a road investment. Then the investor declared that the drivers would go through the tunnel in the second quarter of 2021, which was also not met. Currently, the opening date of the tunnel is unspecified. GDDKiA indicates that it is to take place in the fall.
