Both building complexes consist of in situ cast concrete carcass work. The four-storeyed building parts owe their longitudinal stability to junction stiffening. The higher constructions have been stabilized in both directions by means of concrete walls. The structure of the parking garage consists of hollow-core slab floors with a reinforced compressive layer that is supported by integrated steel beams and prefabricated concrete columns.
The entire complex is founded on Vibro piles. It was decided to not use prefabricated piles: pile foundations from previously demolished quays were still present throughout a large area of the plot, which would significantly increase the breaking risk of prefabricated piles. All piles have been acoustically tested to signal any possible irregularities in the piles’ sections. Since section reductions of less than 30% cannot be detected by these means, this margin has been accounted for while determining the dimensions of the pile sections.
