Mennica Legacy Tower January 2018 Construction Progress Update

Continued progress of the ‘Top-Down’ construction sequence

Construction continues on the two-building Class A Office Mennica Legacy Tower, which will be comprised of a 35-story tower and a 10-story building located in the Central Business District of Warsaw. For this project, Epstein is serving as the architect and engineer of record, as well as the design engineer for MEP and structural engineering services (Our friends at Goettsch Partners are the design architects).

The construction of the Mennica development, due to the site’s relatively high water wall and the adjacent existing subway lines, is utilizing the ‘Slurry Wall’ or ‘Diaphragm Wall’ technique. Tom Suarez, PE, SE, Epstein’s chief structural engineer and designer of Mennica’s structural system explains what can be seen in the construction progress photos featured here:


“The underground construction is complete and the two towers are beginning their above grade construction. The west tower floors, columns and walls are currently up to level 4. The east tower core walls and columns are complete up to the top of the 13.2m (43 feet) high lobby. All construction is of cast in-situ concrete with the floor slabs also containing post-tensioning tendons.”

Lastly, Mennica is scheduled to open in the third quarter of 2019.
