The Norddeutscher Rundfunk (NDR), as the awarding authority, procures the above-mentioned project "Renewal of the S1 complex at Deutschlandfunk Kultur in Berlin" on behalf of and for Deutschladradio (DR).

In 2010, the production and accident broadcasting complex S1 with the control room S1 and the studios S1a and S1b and the central installations for this purpose in the HVT equipment room was put into operation. The built-in central technology of the company DHD is no longer produced, works at the performance limit and can no longer be expanded.
