The complex on the south side of the A10 highway consists of approximately 90.000m2 superstructure and two underground parking levels, providing space for 750 cars over a 22.000m2 area. The building is arranged in a number of sections:
-Two office towers of 105 and 65 metres high. The board of directors seats in the highest tower.
-Four courtyard buildings of five and six storeys, containing the central reception hall, office spaces, conference halls, a restaurant, an expedition yard,
a congress hall and an auditorium.
-A central 55×55 metre dealing room.
The substructure is realised in a construction pit that, on average, lies 9 metres below Amsterdam Ordnance Datum (AOD) and is made out of a concrete structure cast on location.
The towers are characterized by cantilevering façades, wide openings in the façades, voids on various floors and a 6 to 8 metre jettying above the seventh floor. These towers are constructed using a combination of in situ cast, prefabricated and/or prestressed concrete.
The courtyard buildings consist out of prefabricated columns, transfer beams and hollow core slabs. Important deviations from this system appear in spaces that, due to their function, require clean spans of great lengths.
The dealing room is covered with an impressive steel structure, supported by a very limited amount of columns to facilitate optimal communication within the room.
