Berlin’s new airport passes one more hurdle

The smoke extraction system – also referred to as the overriding programmable logic control (OPLC) for Berlin’s new much-delayed future airport – Berlin Brandenburg Airport – had its final test at the end of last week and the hub gets closer to finally opening.

The test was reportedly overseen by the responsible authority TÜV Rheinland (Technical Inspection Association) and was approved without any defects. The TÜV delivered the test reports regarding the highly complex Siemens equipment to the airport on 15 April.

Flughafen Berlin Brandenburg chief exective officer, Engelbert Lütke Daldrup said: “The TÜV-approved smoke control system marks a milestone in the completion of BER Terminal 1. Siemens has completed this complicated system on schedule, and I would like to express my thanks for the good cooperation in this particular situation.

“I would also like to thank the FBB Project Management Team and FBB Team of Experts for the smoke extraction systems that completed the difficult technical installations in BER with tireless dedication.”

The OPLC ensures functioning smoke extraction and controls the interaction between the circulation of fresh air and mechanical smoke extraction, such as between exterior openings and fans.

In the event of a fire, more than 120 smoke extraction machines provide a 8ft (2.5m) smoke-free layer for around 15 minutes, in which time people near the fire can safely evacuate the building.
