The Air Traffic Control Centre (ATCC) in Poznań is an auxiliary facility supporting the operation of the planned hub in Reguły near Warsaw and the main air traffic control service in Poznań. Since the continuity of air traffic control is crucial, the Poznań-based ATCC is a pivotal part of the critical infrastructure. The Centre and its infrastructure require particular security measures. Thus, the main building is planned in the central position of the plot to keep a maximum distance to its external boundaries. Solutions included are designed to isolate the facility and ensure a multitiered access control. Another important step is to provide a functional connection to the existing Avia tower.
The main building has a compact rectangular design. In terms of its architectural arrangement, the building has a minimalist structure that fits well into the entire compound. The main building has a ventilated façade with a steel frame and variable-height corrugation steel sheet cladding; the sheets are set to emphasise the vertical division of the façade. Interiors that require additional access of natural light are fitted with windows and mullion and transom curtain walling system. Door and window frames are also grey. A tall attic section has an expanded steel sheet cladding to reduce noise emission and obstruct the view of equipment set on the roof.
The main building contains office, operation, warehouse and auxiliary functions. Level 0 consists of storage facilities, including a data warehouse (server room and distribution rooms). Levels 0 and +1 are designated to office space, whereas levels -1 and +1 contain ~1272 sq. m main operating rooms that are 6 m in height. These are going to be used to control air traffic. At any one time, interiors should cater for 80 people, assuming that work is continuously provided in three shifts. Interior design is a crucial part of the planned infrastructure, especially that the air traffic control and technical personnel need to ensure operational safety. Thus, it is of paramount importance to provide stable working conditions, free from any external interruption through windows, including variable light intensity depending on weather and daytime. This applies to different illumination of monitors, light reflexes, external stimuli, and the protection against such external factors as noise and electromagnetic interference.
An important part of the designing process includes the planning of specialist installations needed to secure continuous operation of the building in extreme conditions. Redundant utility infrastructure, gas fire suppression systems, multitiered access control, precision air-conditioning, and a system of heat pumps comprise this technologically advanced facility that meets top notch standards.
