TENDER DESCRIPTION

Construction of a footbridge over an existing roller skate track at 28 Jaksonowicka Street in Wrocław The designed footbridge over the existing roller skate track is a steel beam supported on foundations and on steel columns. The beam shall be made from a steel profile (rectangular pipe 300x200x6). The beams are connected to each other with bracing members. A reinforced concrete slab with a thickness of 10 cm is designed on the beams, covered with a thin-layer resin surface. The slabs are to rest on steel profiles on an elastomeric bearing strip 5 mm thick, 50 mm wide, with a strength of 5 MPa. Prefabricated elements shall be stabilized with an M16 screw embedded in the prefabricated element. The prefabricated slab for the steps and the landing is designed from concrete C45/55, exposure class XD3, XF4. The shape slopes are formed through the geometry of the steel structure. The steel structure must be protected with a painting system for environmental class C4 and a long service life. Joints between prefabricated slabs must be filled with a permanently plastic putty/sealant. The handrail on the crossing shall be installed with bolts. Anti-corrosion protections shall be made…
