Quadrio Shopping Centre has undergone a revitalization of the entrance from the lobby of the metro station Národní třída, expansion of the gastronomic zone and modernization of the air conditioning. The construction works, which took place while the building was fully operational, were completed on schedule and now all public areas are open to visitors. Particularly challenging was the coordination of work in the already fully utilised installation shafts and the precise timing of the ventilation system replacement. We also found it technically interesting to use bespoke one metre long core drill bits in confined spaces and to move 2.5 tonne dry coolers on the roof to install new fans.
Two new gastro units were added as part of the foodcourt modifications. In order to meet the increased demands of the new units, the HVAC system was significantly upgraded and the exhaust air extraction system was strengthened. Two dry coolers weighing 2,500 kg had to be moved to the roof to accommodate the new fans. This very demanding project required meticulous preparation and a detailed schedule, with individual activities coordinated to the tens of minutes. From the fan removal, to the fitting of the new cabinets, programming in MaR, to the installation of the last elbow of the HVAC ductwork. The entire upgrade significantly streamlined the overall air handling system of the arcade and contributed to energy savings.
Last but not least, the entrance area from the lobby of the Národní metro station has also undergone a complete transformation. The two existing carousel doors have been replaced by three new, larger, modern carousel doors, which ensure a smoother passage for visitors.
