Skyliner II construction progressing well

Construction of Skyliner II at Daszyńskiego Roundabout in Warsaw, the second phase of Karimpol Polska’s office complex, is advancing rapidly. Since February 2024, engineers and builders have been laying solid foundations for the future skyscraper, with WARBUD S.A. leading the project.

Currently, Skyliner II’s structure is preparing to rise on its robust foundations. Advanced construction technologies have enabled the creation of 33-meter-deep diaphragm walls and 59 reinforced concrete barrettes reaching 38 meters into the ground. These deep foundation elements, along with 42 temporary steel columns, support the bracing and foundation slabs, ensuring the building’s durability. The bottom slab, varying from 1.9 to nearly 5 meters in width, further enhances the structure’s strength.

“The construction of Skyliner II demands both technical expertise and precision due to the existing Skyliner I and surrounding developments. We are well-equipped to meet these challenges and are pleased with the current pace and safety on-site,” said Szymon Zduńczyk, Management Board Member and Managing Director at Karimpol Polska.

Excavation is underway, reaching a depth of 7.5 meters, requiring builders to navigate through layers of embankments, clay, and sand. The next phase involves constructing the bracing slab to facilitate work down to 22 meters deep.

“Skyliner II’s construction is more complex than its predecessor due to the surrounding buildings and traffic system. We have only one access point, requiring precise logistics. Special tilting arm cranes are necessary to avoid collisions with nearby structures. The top part of the building, featuring 15-meter-high slanted attic walls, will be particularly challenging,” said Piotr Pikuła, Skyliner II Contract Director at Warbud SA.

Skyliner II is set to be completed by the end of 2026. The 130-meter, 28-story tower will offer 24,000 sqm of leasable space, predominantly for offices. Ground floor retail and service units will occupy nearly 1,000 sqm, and the top floors will feature terrace gardens connected by an external staircase. The building will have 10 lifts and a five-story underground car park for 217 cars and 100 bicycles. Karimpol Polska aims for a BREEAM Outstanding certificate and plans to power the building with renewable energy.

The architectural design is by APA Wojciechowski Architekci. Hill International is the project manager, and CBRE is the exclusive leasing agent for Skyliner II.
