We are happy to share exclusive insights that highlight the latest project developments important to us and our valued partners and clients.
Thank you for being an integral part of our journey.
Austria
A significant milestone has been reached in constructing the Brenner Base Tunnel (BBT): the breakthrough between two of the three active Austrian lots now forms a continuous tunnel over 12 kilometres long from the BBT's North portal, connecting Lot H21 and Lot H41.
This breakthrough links the area where the two TBMs (Tunnel Boring Machines) of Lot H41 are currently in operation, moving southwards, with the BBT's North Portal and the works of Lot H21. Lot H21, in particular, connects the Innsbruck main station with bridges, cut-and-cover tunnels, and passes under the existing Brenner Highway to the Basetunnel's Northern portal.
In Lot H53, the southernmost lot in Austria, the last two TBMs for the Brenner Base Tunnel have been assembled and have started their northward journey from caverns excavated at the foot of the 3.5 km long inclined access tunnel, Wolf.
As the lead designer in a joint venture for all ongoing work on the Austrian side of the BBT, Amberg Engineering is proud to play a key role in this achievement, contributing to the progress of one of Europe's most significant infrastructure projects.

Amberg Engineering is proud to share a recent win:
The NGE - BTP / Webuild / EQUANS consortium has won the prestigious design-build contract for Lot 2 of Line 15 West of the Grand Paris Express, linking the stations of Bécon-les-Bruyères and Saint-Denis-Pleyel: Amberg Engineering is a proud member of the engineering consortium led by TRACTEBEL, in collaboration with AIA, GESTE Engineering, and GROUPE BETEM.
This contract, worth €1.38 billion, marks a crucial step in constructing the longest metro line in France. Of the 75 kilometres and 36 stations of this new line, our team is responsible for constructing 7 km of tunnels and railways, 4 stations, and 6 service structures.
Laurence Delplace, CEO of Amberg Engineering, underlines the importance of this success: "What a pride for all the teams who worked together on this magnificent achievement. This project will be monumental for the years to come and will be the culmination of an extraordinary human story. Participating in this project, full of interesting challenges, is a huge honor. Congratulations to all the partners, and a huge thank you to NGE - BTP, Webuild, and Equans for leading us to victory."
Congratulations to all our partners: NGE GENIE CIVIL, TSO, TSO CATENAIRES, Guintoli, NGE FONDATIONS, TRACTEBEL, GESTE Engineering, AIA Ingénierie, and Betem Ingenierie.

The official ceremony for the excavation start and the blessing of St. Barbara took place at the Kaiserstuhl Tunnel on July 1, 2024.
After several preliminary lots, in which the pre-cuts and the exploratory tunnel were created, the main lot is now underway: the construction of the 2-lane road tunnel, including the stop bays and cross-connections. In addition to the underground work, a 190-metre-long cut-and-cover tunnel and two centrals for ventilation and operation will also be built at the portals.
After passing the nearby pressure pipeline with reduced loading quantity the drilling and blasting of the rock stretch can increase to full performance. The excavation in the challenging soft ground on the southern side of the tunnel is conducted with the support of a jetting umbrella and jetting piles in the tunnel face.
Parallel to the excavation works, the concreting of the cut-and-cover tunnel in the north is already underway, leading to a very busy construction site. Amberg Engineering has been involved as the project author since the general project (2012) and, as with the preliminary lots, is responsible for the construction management of the Kaiserstuhl Tunnel.
A big thank you to the entire project team for their work so far, and good luck with future progress!
