The N3 motorway junction Brugg is connected to the subordinate network via the Seebli junction. The junction is heavily congested, and there is a traffic jam on the motorway during peak hours. In the event of a further increase in congestion, there is a risk of a backlog up to the Birrfeld junction (N3/N1) and thus a direct influence on the performance of the N1 Zurich-Bern.

The Canton of Aargau, together with FEDRO, has examined various variants for the rearrangement of the Seebli junction and selected a best variant. These must be questioned and consolidated in a first phase. For this purpose, the actual project elaboration as an execution project according to NSG/NSV or as a construction/support project according to SIA is to be preceded by a variant in-depth study.

The subject of the advertised mandate is client support services across all trades.
