Switzerland – Engineering services – N05.80 MP-220010 - EM Bözingenfeld - Lengnau - Bauherrenvermesser (ID 12023) Phase MK / AP - IBN / Abschluss

The project perimeter is located on the national road section N05.80, Bözingenfeld – Lengnau and includes 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 UNF Bözingenfeld N16 (BS 03) was created 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 ponds, 2 pump shafts, and 20 signal portals. The renovation includes the following works: resurfacing along the entire route, the conversion of the 4 rainwater retention basins, various concrete repairs on structures and in the Pieterlen tunnel, local reinforcements at signal supports, various hydrophobizations on structures, replacement of the surface protection system in the Pieterlen tunnel, markings, signage, and lighting along the entire route. The connection Biel Ost / VZW Bözingenfeld, which is considered an accident blackspot and is located in the development focus Bözingenfeld, must be checked for traffic. At present, it is assumed that structural measures will be necessary. The current procurement includes the mandate for surveying for the phases MK / AP until commissioning using the planning method BIM.
