'Unique and complex steel construction'

For Amsterdam Logistic Cityhub (ALC), Reijrink Staalconstructie realized about 2,300 tons of structural steel and about 290 tons of auxiliary steel - from design to assembly. The lion's share (1,700 tons) of the production was incorporated into the 24-meter-high warehouses. "This 12-meter-high steel main structure was realized on a 12-meter concrete substructure, i.e. a hybrid building structure," explains project leader Corné van Roovert.

The main structure of the warehouses is built with composite trusses. From a concrete "table," specialist in complex steel structures Reijrink, together with Vrolijks Prefab Betonbouw, erected concrete and steel simultaneously in a logistical pendulum motion. "We used about 150 main trusses and 325 supporting child trusses for this. "For the construction of the two upper office floors, Reijrink Staalconstructie assembled about 600 tons of heavy steel beams and columns, which support the hollow-core slab floors. For the assembly of ALC's facade cladding, Reijrink Staalconstructie made a steel substructure totaling 290 tons. The steel structures for the warehouses and offices were completed in June 2022. Subsequently, Reijrink Staalconstructie assembled the final steelwork, including for the ramps of the 'circulation deck' (the supply deck at a height of 12 meters) and the foot structures of the wind turbines on the roof.
