Switzerland – Engineering works and construction works

The Tavannes - Bözingenfeld upgrade plan extends between kilometer markers 69.250 and 82.660 of the N16. This tender concerns exclusively the section between the La Heutte interchange [19] and the Biel-Nord interchange [23], namely from kilometer marker 76.100 to 82.660 (L = ~6.7 km). It is a Class 3 line in two separate sections: an uphill section (TP2) and a downhill section (TP3) between La Heutte and Biel-Nord. The sections consist of underground structures and walls (T/G), engineering structures (K), open sections (T/U), and electromechanical equipment (BSA). All affected structures are listed in detail in the attached inventory plan in the technical dossier. The main achievements of the preliminary works include: - The construction of the industrial zone connection (including bridge D19 and bridge D19 A - T/U and K) - Cantilevers D09 and D17 (SBB safety net systems - K) - The construction of the underpass D07
