Structural Demolition and Concrete Works for Ruhrstraße Complex Modernization

This tender relates to the structural demolition and concrete works for a modernization project in the Ruhrstraße complex in Berlin. The project involves a significant amount of excavation (1,200m3), shoring via sheet pile walls (430m2) and soil stabilization using HDI-walls (175m3) and micropiles (190m). The new construction aspect includes substantial in-situ concrete work (2,360m3) requiring 12,900m2 of formwork and 362t of rebar. The scope also encompasses masonry (3,535m2), internal steel construction (14t), roof steel construction (58t), bitumen waterproofing (6,000m2), insulation (550m2), lime-cement plastering (8,500m2), and concrete repair (4,000 m2) on walls. Waste disposal is also included as a key task. The complexity indicators point to a medium-sized project with varied work packages including demolition, ground works, and steel/concrete construction.

The deadline for submissions is May 6th, 2026, providing approximately seven weeks for tender preparation. Given the mix of demolition and new construction, contractors should assess their capabilities across these areas. Specifically, experience with specialized shoring techniques (HDI-wall, micropiles) would be advantageous. The relatively large volume of concrete work combined with the steel construction component indicate a structure requiring substantial load-bearing capacity. Contractors should also note that the published information is for the first construction phase (Gebäudeteil F 76760) of the overall Ruhrstraße complex modernization, so future phases are possible.
