Another report of cracks in a building due to the construction of the metro to the "Slatina" neighborhood, reports BNT. People from an apartment building have noticed cracks on the facade, and the staircase has come off. The capital's "Metropolitan" assures that there is no reason to worry. A week ago, there was a report of cracks in the 93rd school in the area, which is located next to the metro excavation at the intersection of "Geo Milev" and "Kopernik" streets. The so-called "mole" will soon start working there and residents are worried that the vibrations will become even stronger.
Nikolai Narizhin is a geodesist by education, who noticed newly formed cracks along the block where he lives. The extension of the third metro line is currently being built there, which will reach the "Slatina" through "Sofia Techpark". At the moment, the excavation is right in front of his block.
Nikolai Narizhin: "I have been observing these cracks growing in the ground here for several months, I paid special attention to them after the report about the school and discovered that the cracks are within the scope of the excavation."
Nikolai Nikolov, the owner of a store: "This crack is constantly expanding, in my opinion.
BNT: Is it worrying? - Not much so far, but…"
Nikolai uses an interior level and discovers a worrying trend that the buildings along the trench are leaning towards it. Although very slightly. Block 21 also sends a signal to the DNSK. They are told that no deviations have been identified in the approved projects. People still insist that the trench be strengthened better.
Nikolai Narizhin: "It is not strengthened adequately, it is strengthened, but weakly, and this creates serious risks and concerns for all residents, we are startled by every night noise, wondering if we will fall."
"Metropolitan" replied that the construction of the metro station was carried out using the so-called Milan method, with stability ensured by slotted walls. And more. that before the start of construction, benchmarks and geodetic marks were placed on all buildings in the area of influence, including block 21.
For September, the deviation is 2 mm for the entire construction period. This deviation is minimal and falls within the permissible instrumental error. And while the institutions assure that there is no problem, residents in the area watch the construction under their windows with distrust every day.
