Mennica Legacy Tower - April 2018 Construction Progress Update

East Tower Begins Vertical Climb & West Tower is Topped-Out

Construction continues on the two-building Class A Office Mennica Legacy Tower, which will be comprised of a 35-story east tower and a 10-story west 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 high-rise east tower is now starting its vertical climb. After a long schedule sequence completing the atypical lower floors the repetitive typical floors are into production mode and the construction pace should increase significantly. For the rest of the east tower one level will be completed every 5 to 7 days. In pictures seen below we see the self-climbing formwork of the core walls and the reinforcing and post-tensioning cable layout of the sixth floor.  If you look very closely you can even see the notching of the slab edge which will give the tower its distinctive saw-tooth façade.


In pictures below we also see the concrete frame of the topped-out west building with most of the formwork shoring and re-shoring removed. Here we also start to see the initial installation of the curtain wall façade.’


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