Yesterday, March 7th, a cornerstone ceremony was held in Warsaw, Poland for the Mennica Legacy Tower, a two-building high-rise Class A office development which will be located in the Central Business District of Warsaw at the intersection of Prosta and Å»elazna Streets. 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. Mennicas design architect is Goettsch Partners and the project is being developed by Golub GetHouse.
At the ceremony, Cezary JarzÄbek, the founder and President of the Board of Golub GetHouse, said, The laying of the foundation stone marks a new stage in the Mennica Legacy Tower project. We are convinced that it was worth taking up the development of the most technologically advanced office complex, which, thanks to its magnificent architecture and ergonomic solutions for tenants, will become a permanent image of the modern center of Warsaw.
Representing Epstein at this event was Janusz Lichocki, the president of our Polish-based subsidiary, Epstein sp. z o.o.
When complete in 2018, Mennica Legacy Tower will feature a 35-story tower located on the south east side of the site and a smaller 10-story building on the west side of the site. Mennica consists of approximately 100,000 gross square meters, with 80,000 gross square meters of Class A office space which includes a conference and a fitness center as well as ground level retail. Four levels of underground parking and ancillary services encompass the remaining 20,000 gross square meters. Between the two structures is a large open plaza that provides ample space for outdoor seating and a variety of landscape features.
As the lead MEP engineer Epstein designed an array of sophisticated mechanical and electrical systems for the main tower. For instance the chilled water plant will consist of multiple water cooled chillers, pumps, and closed type cooling towers and the complex will be heated from the district heating mains via a central heat exchanger plant. Mennicas air handling system for the typical office will consist of multiple roof/ technical level mounted air handling units configured with rotor or glycol type heat exchangers. The electrical system will be powered by two MV (15 kV) cables connected with 2-section MV switchgear and the lighting systems for this project will consist of a combination of high efficient fluorescent and LED for general lighting, LED task lighting in offices, and LED site lighting.
Mennicas structural design features a collaboration between Epsteins Chicago and Warsaw offices. The 35-story tower structure is of cast in place concrete construction with a pile supported raft foundation under a central core that cantilevers up to 8.2m from its base footprint to deliver column free post-tensioned concrete flat slab interior spans. The 10-story building is also of cast in place concrete construction with a central core and post-tensioned concrete flat slab interior spans. The four below grade levels will include a perimeter slurry wall and will be built utilizing the top down construction method.
Lastly, Mennica has been designed to achieve BREEAM certificate at "Excellent" level.
