Germany – Engineering services – Erweiterung der Elektrischen Lautsprecher-Anlagen (ELA) - Planungsleistungen technische Ausrüstung

Lot 1 includes subway lines U1, U5, and U6. After more than 30 years of operation, the life cycle of many public address (PA) control centers and loudspeakers in the subway stations of the Berlin Transport Authority (BVG) has reached its technical performance limit (EoL). The existing analog amplifier systems are no longer capable of controlling and outputting automatically generated announcements. Therefore, all PA control centers are being equipped with digital technology. This sub-project is already underway. Commissioning is expected to be completed by March 2025. This contract covers planning services according to the German Fee Structure for Architects and Engineers (HOAI) for the construction of approximately 4,000 new loudspeakers in the 214 station concourses and the modernization (dismantling/replacement/disposal) of approximately 9,300 loudspeakers (including supply lines/cables) on almost all platforms of the nine BVG subway lines. The loudspeakers and public address (PA) control units will be connected to an IP network, providing automatic audio output that reacts to relevant events on the platforms, in the concourses, and later also inside moving trains. Furthermore, the standard sound levels (STA values) of the loudspeakers will be adjusted to at least an "appropriate" level. 214 concourses of the subway stations will be equipped with approximately 4,000 loudspeakers to enable acoustic intervention in the event of security incidents detected by video, to guide passengers in the concourses during operational disruptions, such as major events or rail replacement services, and to expedite station evacuations in emergencies. Enabling announcements in station concourses: • in case of operational incidents (security incidents, operational deviations, crises) • passenger guidance in concourses (e.g., rail replacement bus services) • in case of necessary station evacuation. To improve the quality of announcements on the platforms, over 9,000 loudspeakers on...
