Award International Tunnelling Association (ITA) project of the year

BeMo will be hosting the British-Tunnelling-Society's Young Member Evening Lecture on 7th November 2019.

Christoph Huber will be holding a presentation on

New Austrian Tunnelling Method in Hyperbaric Atmosphere
Christoph’s presentation will explore the challenges and innovative solutions associated with the application of New Austrian Tunnelling Method in hyperbaric atmosphere during the con-struction of Tunnel Karl-Friedrich-Strasse in Karlsruhe (Germany). The project – Shortlisted for NCE Tunnelling Festival’s ‘Innovation in Tunnel Excavation’ award – posed a unique challenge with its small overburden (approximately 7m), a poor geol-ogy consisting of gravel, sand and fine sand and layers of rolling gravel. Given the tunnel’s variable geometry (of up-to 180m² tunnel face; 15 m diameter), NATM was chosen as the preferred excavation method. However, due to the inner-city location and a very high water table, the excavation had to be carried out in a hyperbaric atmosphere, of circa 1.0 bar, which created special challenges for the application of wet mix shotcrete. Other challenges included: air losses and the corresponding air flow, and the presence of his-toric buildings along the path of the excavation (including a 125y old brick lined sewer directly above the tunnel alignment).

BeMo is pleased to announce that is has been shortlisted for the New Civil Engineer Tunnelling Awards in the category

Innovation in Tunnel Excavation

The winners will be announced at the Tunnelling Festival 2019 on 5th December. For more details go to

BeMo has been awarded the relocation of the B23 west of Garmisch-Partenkirchen and the construction of the 3.6km Kramertunnel by Bavarian State Construction Office StBA Weilheim. Construction for the by-pass tunnel project will start in December 2019 and completion is expected for September 2023.

We wish all project participants a successful start!

Glück Auf!

On our Civils/Industrial Construction project Ilsenburg we have completed the largest single concrete elements: the largest single concrete element on the cooling bed 2 was cas with dimensions of approx. 50.0x20.0x2.30 m with approx. 2,300 m³ of concrete and subsequently a section of cooling bed 1 with approx. 1,200m³. The assembly of the steel construction for the plant is scheduled to begin in April 2019.

On our bridge replacement project Volmarstein (motorway BAB 1) the demolition of the first superstructure (driving direction Bremen) was successfully completed. The foundation work for the new bridge pillars has begun. The new bridge in the driving direction Bremen is to be completed by May 2020. After completion, 3 traffic lanes will be set up for each direction over the new superstructure (traffic guidance 6 + 0). Thereafter, the demolition of the second superstructure (driving direction Cologne) will commence.
