He also said that the union has asked the Russian Academy of Architectural and Building Sciences to examine every possible cause of the collapse. "Such examinations are already being held with the help of a closed institute". "There is a version that the column has been hit by a projectile fired from the forest 100 meters away from the water park", Logvinov added.
Additional examinations will supply new information on the Transvaal-park tragedy, the president of the Moscow Architects' Union is sure.
The main designer of Transvaal-park Nodar Kancheli has reiterated today that the water park has collapsed because one of the supports was affected by something from outside. He recalled that a video tape recording the tragedy was shown soon after it. "At one moment a cloud as if burst out from one of the columns, after which the column bent and slipped out from the support contour", he said. To Kancheli, this has caused the roof collapse with the subsequent fall of the other columns.
Kancheli argues that he had seen the bent column in the place of collapse, while the others actually remained intact.
"On the next day all the columns were drawn out from the debris, crashed and dumped in the nearby ravine", he said. And noted that "the video tape showing the moment of collapse has also disappeared. At least, members of the fact-finding commission have failed to see it, just as the broken column".
The designer said that on Tuesday, March 30, the fact-finding commission was offered to study the preliminary conclusion on the causes of the tragedy. The document "categorically and unequivocally" said the designing errors were the cause, Kancheli said.
The commission is made up of representatives of the State Commission for Construction, general contractor companies building the water park, specialists from the designing company, other organisations.
Nikolai Koshman, head of the State Committee for Construction, now being closed, said that the fact-finding commission has sent the collected materials for a more detailed study of the causes of the tragedy to the Defence Ministry.
As result of the roof collapse of Moscow's Transvaal-park on February 14, 28 people have died and more than a hundred were wounded.
