RECONSTRUCTION OF THE FIRST MASS SERIES BUILDINGS AS THE PRINCIPLE OF THE SUSTAINABLE DEVELOPMENT OF NEIGHBORHOODS AND RESIDENTIAL QUARTERS IN CITIES

Abstract

The residential buildings of the first mass series of the 1960s-1970s form a significant part of the housing stock of Ukraine. The main load-bearing structures of
the most buildings of these series are in satisfactory conditions, and with proper repair they can be operated for another 40-50 years. The modernization
of the first mass series housing stock involves the intervention in the neighborhoods and residential quarters systems characterizing the mass construction.
The destruction of such systems contradicts the principles of "sustainable development". On the territory of Ukraine, in the sixties-seventies of the last century more than 5,000 five-storey large-panel residential buildings were built, mainly of 1-464 and 1-480 series. The large-panel structures design features allow their reconstruction with size- and time-limited interference in the residents lives. Such reconstruction envisages only the changes of the vertical building dimensions. The appropriate reconstruction schemes recommended for the mentioned buildings series are based on the arrangement of superstructures or superstructures with added small risalits in the inner quarter space. The problem of superstructures is the use of slabs with the reduced load-bearing capacity in the enclosing ceilings. The solution is to install the doubled separate floors. The Flamingo design system provides for a five-storey superstructure adding, which can be used as the vertical "accents" of new neighborhood development. The structural concept of the system is to create the П-shaped load-bearing frames on their own foundations. Framework beams become the basis for the space used as a technical floor. The 1-480 series buildings are the most suitable for the reconstruction. The current requirements to the reconstruction of five-storey residential areas should include a moderate increase of the number of floors in buildings, without expanding their sizes in the plan. The additional floors should be added to create the vertical accents of quarters. The new public buildings should be the focus of neighborhoods. These architectural urban planning solutions will correspond to the concept of "sustainable development".
