The subject of the contract is the complete reconstruction of the underpass roof structure above the stairwell area. This includes the removal of the existing roof structure, along with the surrounding soil and adjacent asphalt surfaces.
The new roof structure consists of a steel load-bearing framework with roof and wall infill made of glass panels. The original reinforced concrete covering of the underpass entrance will be replaced with a new steel structure.
The spatial structure is designed with a strong architectural intent. Installation will be carried out using a mobile crane from a reinforced surface. Columns and other steel elements are anchored into the existing reinforced concrete wall and the elevator shaft.
The entire load-bearing structure is designed using steel tubular sections. The vertical load-bearing elements consist of four steel columns finished with spherical joints. In addition to the main columns, the structure is supported by intermediate posts and bracing elements.
The reconstruction of the roof structure will not alter the original ground plan of the building. The proposed renovation of the underpass entrance aims to improve both the technical condition and architectural appearance by introducing a modern roofing structure that connects the underpass with the exterior.
The steel structure incorporates specialized details such as tension rods and glass panels fixed using spider fittings.
