The work concerns the overhaul of the entire exterior envelope, where the plastering of the facades is completely dismantled and renewed as a three-layer plastering, the windows are renovated, and the existing waterproofing and thermal insulation structures are dismantled up to the load-bearing concrete frame and renewed. To direct the water from the roof, gutters and new downpipes will be built on the water roof. Downspouts are added to the central areas of the long facades. New rainwater wells embedded in the asphalt will be built at the added downspouts, which will be connected to the nearest existing rainwater and/or stormwater wells. The steel structures supporting the process pipes running between buildings 9 and 6 will be renovated.
