Switzerland – Engineering services – N05.80 MP-220010 - EM Bözingenfeld - Lengnau - Projektverfasser Verkehr (ID 11948) Phase MK / AP - IBN / Abschluss

The project perimeter lies in the national road section N05.80, Bözingenfeld – Lengnau and comprises the section from the Bözingenfeld junction to the Leugene Bridge (BS 20), from km 73.965 to km 81.195. This corresponds to a length of 7.23 km. The section of the N16 between VZW Bözingenfeld and the bridge ‘Pont sur T5’ (D01) belongs to the maintenance section N05.80. This section was predominantly built between 1998 and 2000 and was put into operation in 2001. The Bözingenfeld N16 underpass (BS 03) was constructed in 2020. This is the national road N05, 1st class, which is owned by ASTRA. Within the project perimeter, there are 8 overpasses, 4 underpasses, 4 culverts, 1 trough, 6 retaining walls, 1 tunnel, 5 noise barriers, 5 noise walls, 2 oil retention basins, 2 pump shafts and 20 signal portals. The renovation includes the following works: resurfacing the entire route, the reconstruction of the 4 rainwater retention basins, various concrete repairs on structures and in the Pieterlen Tunnel, local reinforcements at signal carriers, various hydrophobizations on structures, replacement of the surface protection system in the Pieterlen Tunnel, markings, signage and lighting along the entire route. The Biel Ost / VZW Bözingenfeld junction, which is considered an accident blackspot and is located in the development focus area of Bözingenfeld, must be checked for traffic management. At present, it is assumed that construction measures will be required. The Lengnau junction is also considered an accident blackspot. At present, it is assumed that construction measures will be required. The current procurement includes the mandate for the project author for traffic for the phases MK / AP with PGV (procedural support, handling of objections) up to realisation / IBN using the planning method BIM.
