At Frankfurt airport Deerns has worked on several projects since 1969. A recent example is the rearrangement of concourse B to allow handling of the Airbus A380. Two parking positions are now able to handle the airbus A380 smoothly
In parallel the building design was amended to separate arriving and departing passengers, and to complete revamp the commercial areas. During the construction the airport was fully operational. The M&E systems were updated technically and integrated in the existing buildings service systems. With a constant project flow, Deerns Germany continuously helps Fraport remain an important European hub.
