Project description<\/p><\/h2><\/div>

The museum complex is being developed on the site of the former Bersohn and Bauman Children\u2019s Hospital at 60 Sienna Street \/ 51 \u015aliska Street in Warsaw. The total planned usable floor area of the Warsaw Ghetto Museum is approximately 11,500 sq m. The project includes approximately 3,400 sq m of usable floor space dedicated to the permanent exhibition, divided into nine galleries. The museum complex will also include an Education Centre located in the historic building of the former Ophthalmology Pavilion, a 150-seat auditorium, collection storage facilities, and space for temporary exhibitions. Once construction is completed, the site will comprise three buildings \u2013 two historic structures and one newly constructed building \u2013 all interconnected by an underground car park and underground passageways.<\/p>\n<\/div>

Soletanche Polska scope of works<\/p><\/h3><\/div>

Our scope of work included the preparation of the detailed execution design covering the construction of guide walls, diaphragm walls, barrettes, a reinforced concrete capping beam, and the underpinning of the former Children\u2019s Hospital and former Ophthalmology Pavilion. The project required the mobilization of specialist equipment for diaphragm wall construction and the use of jet grouting technology.<\/p>\n<\/div>

Technologies applied<\/p><\/h3><\/div>

As part of the project, we constructed guide walls and underpinned the former Children\u2019s Hospital and Ophthalmology Pavilion using jet grouting technology. We subsequently constructed diaphragm walls while carrying out barrettes in parallel. We also constructed a Berlin-type retaining wall system using CFA piles \u2013 continuously flight auger piles installed with a continuous-flight auger drilling rig. The technology we applied secured an underground fire protection water tank located in a straight line towards Twarda Street, as well as an underground heat exchanger room designed in close proximity to the former Children\u2019s Hospital on the \u015aliska Street side.<\/p>\n

Upon completion of the main scope of works, we proceeded with the installation of struts across three underground levels, thereby opening up the work front for the construction of the slabs and subsequent structural works.<\/p>\n<\/div>

Foundation reinforcement<\/p><\/h3><\/div>

\n

The first major challenge that required exceptional precision and caution from our Soletanche Polska team was the reinforcement of the foundations of the pre-war buildings that formerly housed the Children\u2019s Hospital and Ophthalmology Pavilion. The effectiveness of the works was confirmed by the absence of any recorded building movements during their execution.<\/p>\n

\u2013 We constructed a total of 206 jet grouting columns. This technology enables us to precisely reinforce the soil around the building, ensuring the stability of the structure. The process can be carried out without the need for extensive excavation, which minimizes disruption to the surrounding area and reduces the risk of damage to the historic building itself. In many cases, jet grouting can help extend the service life of historic structures by protecting them against degradation and enabling their continued use<\/em> \u2013 says Dominik Skubisz, Site Engineer at Soletanche Polska.<\/p>\n<\/div>\n<\/div>

Diaphragm walls<\/p><\/h3><\/div>

We constructed diaphragm walls along the perimeter of the site, covering nearly 326 linear metres. The walls are 100 cm thick and reach depths ranging from 28 to almost 34 metres. The excavation within the diaphragm walls reached a depth of 16 metres, corresponding to three underground levels.<\/p>\n

We began the works in the immediate vicinity of the former Children\u2019s Hospital, where we constructed 10 of the 66 planned diaphragm wall panels. In addition to their primary function as part of the foundation system for the museum complex, the walls also form the retaining structure for the underground car park and the museum\u2019s underground sections.<\/p>\n

\u2013 The historic buildings presented a particular challenge for us and required exceptional care throughout the geotechnical works. Their structures were subjected to significant engineering demands: we first underpinned their foundations and then proceeded with the construction of large-scale diaphragm walls just one metre from the fa\u00e7ades. To minimize the risk of structural movement and ensure the safety of the historic buildings, we constructed narrower panels in their immediate vicinity than are typically used with this technology. Instead of the standard panels, which are approximately 7 metres wide, we constructed panels measuring 3.30 metres in width<\/em> \u2013 says Dominik Skubisz, Site Engineer at Soletanche Polska.<\/p>\n<\/div>
