Za Bramką, Poznań

The street Za Bramką (“behind the gate”) is a narrow cobbled street in the very center of Poznań, leading to among others to the City Hall. This is where the multi-level, underground parking is constructed, what makes it easy to find a parking place when you are going to set up administrative matters.

The parking will accommodate about 300 cares on 3 underground floors and ground floor. Additionally on top of it there is a A class office space with cascade shaped floors ensuring day light for neighboring buildings.

Due to irregular shape of the plot and directly neighboring old buildings, most of them in bad technical condition, realization of this project was a huge challenge. The superstructure was designed as RC structure. The underground part was surrounded by diaphragm wall and constructed with top-down method.

Bartels has provided engineering services for concept phase, prepared technical due-diligence of surrounding buildings with necessary protection and supporting, permit design and construction drawings. This project was realized in formula “design and build” by general contractor.
