The main scope of works, apart from erecting walls with an emphasis on high quality of concrete surface – architectural concrete (ALFA wall system) and ceilings (PAL-20 gantry system), were atypical design solutions. The oblique circular poles were distinguished in terms of construction and execution. The project assumed various types of diameters and up to 9 angles of inclination relative to the ceiling. To implement these elements, Palisander engineers proposed 6 types of special formwork.
