Skyliner II, the sister skyscraper of the office complex in the heart of the capital city’s Wola district owned by Karimpol Polska, has a strong foundation. The work on the building’s foundation has been completed. The general contractor Warbud SA has put in place the last section of the concrete foundation slab at a depth of 22 metres. Work on the underground structure is entering the next stage. The construction of the superstructure will begin once the building, whose foundation has been placed using the top-down method, has reached ground zero.
