The excavator confirmed the expert's conclusions (video)

On Grafova Street, the confrontation between residents and developers, who are supported by the district authorities, continues.

The examination revealed glaring shortcomings in the work, and on the same day, as if confirming the commission’s conclusions, an excavator fell under the asphalt.

Along Grafova Street, Rosengineering LLC is laying a heating main intended to connect the Riverside residential complex (developer Settle City). A trench is being dug next to residential buildings, and a crack has already formed on one of them ( see “New” dated June 1, 2016 ).

And on June 14, one of the excavators partially went underground: the asphalt cracked under it, the bucket hit the roof of the pedestrian gallery that the builders had built along the house, jumped off it and crashed against one of the piles reinforcing the walls of the pit. Hearing and feeling the blow, the residents rushed to the windows: had it really started and the house began to slide? But for now it's gone.

It started pouring out right away

Judging by the information on the GATI website, Rosengineering’s permit for excavation work expired on June 14. Apparently, on the last day the builders decided to work at an accelerated pace.

Opposite the second front door of building 31 on emb. They dug a deep hole in the Black River and placed a concrete pipe splitter in it. The pit itself was reinforced with wooden walls on iron piles. According to residents, sand was falling from under the asphalt and water, which abounds in local soils, was pouring. Which could not but affect the safety of the house, because its foundation is located just a couple of meters from the pit. The posts of the wooden gallery, which the builders laid along the house for the safety of pedestrians, were askew. A crack has formed between the wall of the house and the asphalt.

So much sand spilled out from under the asphalt that it could no longer support the weight of the equipment. Only thanks to the bucket, which rested against the piles, the excavator did not fall completely underground. They pulled it away, leaving only a hole in the asphalt, which the workers are trying to mask with sand.

Avoid soil displacement and water filtration!

As follows from the expert assessment of Professor Igor Sakharov, an expert of the commission on foundations, foundations and underground structures at the KGA, the calculations of the designers on Grafova Street do not stand up to criticism: “The development of a trench will lead to the danger of a slope collapse and an emergency displacement of the foundation of house 31. Fencing project completed by a specialized organization with relevant experience, must prevent soil displacement and water filtration into the excavation.”

For further information, the professor advised the designers to turn to the textbooks that he himself wrote.

Before the appearance of the expert assessment and the emergency with the excavator, Rosengineering assured that there were no reasons for prohibiting construction and installation work at the moment and all regulations were being observed: “There is no impact of the complex of works on the facades and foundations of the above-mentioned houses.”

In light of recent events, Novaya sent a request to the contractor, but we have not yet received a response.

The expert assessment was presented to Vice-Governor Igor Albin by Legislative Assembly deputy Boris Vishnevsky. Albin gave orders to look into the situation.

“It is possible that alternative options for heat supply to Riverside will be considered,” Vishnevsky explained. “The work must be stopped immediately, as there is a direct threat to the house and people.”

“Despite the expiration of the GATI order, work continued on June 15 and 16,” says Nadezhda Gagulashvili, an activist from building 31. – On the morning of the 16th we called the police, this was the only way to stop the work. The authorities, the customer, the contractor constantly convince us that “everything is under control.” But what kind of trust can there be in them after such disregard for the law?”
