ABD Architects and Perkins Eastman Architects started their work on "Dinamo" stadium reconstruction project from the detailed analysis of the town-planning context, which is quite complicated. One of the difficulties according to both Moscow and New York architects was the need to place the object of mass attendance at the intersection of transport and pedestrian flows, saving the natural park and a cultural monument. There were two debatable issues: placement of the Hall and Gallery. Idea to locate the Hall in the place of existing football training field and indoor Dynamo arena destined for demolition was rejected at once. As the result of "Petrovsky Park” construction the existing pedestrian route, connecting the residential areas along the streets of Verhnyaya and Nizhnyaya Maslovka and the subway, is cut off. New sports facility would cut off the left pass, whereas the trade centre on the contrary could make pass for pedestrians. Another reason for Hall location choice was the location relative to the subway and park. Analysis of the games schedule (football / hockey / basketball) showed that this sports facility will be used operating almost daily, oftener than the Arena. It was clear that daily 5 or 10 thousand people will ruin the park. So they decided to combine the two sports objects in the historic "Dynamo" stadium. This was possible due to the fact that it was built as an athletics stadium, which is larger than a football one. American partners offered also to insert the Gallery into the historic building, raising the football field at the mark of + 12.00 meters. However the idea was set aside for several reasons. First, it would be unsafe to place shopping center and parking areas with uncontrolled access directly under the football field. Second, there is enough area to ensure the evacuation around the stadium (0.5 sq m per person, i.e. 40,000 evacuated require 2ha according to the regulation), overloading it with numerous entrance ramps would mean lack of “air” (according to safety requirements access to the stands should be dispersed, and each sector must have their own entrance). Besides, the ramps would have blocked much of the historic facades. And finally, the most important consideration: the mark of the field, raised at 12 meters above the ground level, automatically raised the construction height over 60m. The architects considered it unacceptable from the point of preserving the image of the historic buildings and panoramas of the Leningrad highway in general.
