Zagreb, 27 November 2025 (Hina/MIA) — Demolition crews have yet to set a firm date for bringing down Zagreb's Vjesnik tower, but it will most likely be toppled using explosives, a method that would require hundreds of kilos of charges, according to Mario Dobrilović, a professor at the Faculty of Mining, Geology and Petroleum Engineering.

Dobrilović, who inspected the site Wednesday, told Hina the demolition would take place in a few weeks. A precise date has not been set as a detailed plan must be completed first.

He said he was in daily contact with the Ministry of Physical Planning, Construction and State Assets, which has yet to make a final decision on the demolition method. But after assessing the building's condition, he believes blasting is the best option. The final call will be made by the competent authorities.

"For blasting, we are talking about several hundred kilos of explosives, not tons," he said, adding that the collapse itself would last only a few dozen seconds, up to half a minute.

On safety measures, Dobrilović said every precaution must be taken to avoid risks, with the safety zone likely to follow the same perimeter now used for traffic regulation.

"We don't expect major evacuation measures. The Interior Ministry will issue clear instructions to residents in nearby buildings. One option is for people in the closest buildings to leave their flats for half an hour; the other is to lower blinds and open windows to reduce noise, air pressure and dust."

Traffic would need to be halted for about 30 minutes, and all public access to the area restricted.

Only certain elements at the lower levels of the structure will be packed with explosives, he said, adding that the loading process usually takes one day.

Dobrilović said he had no estimate yet of the overall demolition cost.

As for damage to other buildings within the Vjesnik complex, he said part of the annex would be destroyed while the rest would remain intact. Some structures on the western side, where the tower is expected to fall, will also be affected.

Police have charged and detained two 18-year-olds for allegedly causing the Nov. 17-18 fire that heavily damaged the tower.
