Refurb<strong>is</strong>hment & Reinstatement<br />
Safety engineering upgrade, Arlberg Tunnel<br />
The Arlberg Tunnel <strong>is</strong> a 2-track railway tunnel. The enlargement and upgrade was necessary due to<br />
new tunnel safety regulations. Six escape exits and six niches were built. The ex<strong>is</strong>ting<br />
h<strong>is</strong>torical stone masonry was enlarged, cleaned and reinforced. Furthermore, the invert of both<br />
tracks was deepened and a ballastless concrete track slab system was built.<br />
Modern<strong>is</strong>ation, Alte Mainzer Tunnels<br />
For modern<strong>is</strong>ation and enlargement of the very shallow Alte Mainzer Tunnels in soft ground, an<br />
innovative grouted anchor system was installed according ABT’s special proposal. The systematic<br />
ground pre-strengthening around the ex<strong>is</strong>ting tunnel has reduced settlements to a maximum of<br />
10 mm and allowed to abandon the installation of compensation grouting.<br />
ABT’s innovative grouted anchor system has<br />
reduced settlements to a maximum of 10 mm.<br />
FEATURES<br />
Safety engineering upgrade, Arlberg Tunnel // All construction had to be done<br />
without interrupting railway-operations. Th<strong>is</strong> was achieved by closing one track and<br />
keeping the second one in operation.<br />
Modern<strong>is</strong>ation Alte Mainzer Tunnels // Construction, Design & Structural<br />
Engineering by ABT and the challenge of underpassing main roads, buildings and<br />
ancient walls.<br />
Know-how Transfer<br />
Tysons Corner, Silver Line, Dulles Corridor Metrorail Project (DCMP)<br />
Our know-how and <strong>our</strong> experience in tunnel construction are in increasing demand abroad. We<br />
also export <strong>our</strong> know-how to the United States, e.g. for the project Tysons Corner, Silver Line,<br />
DCMP near Washington D.C.. Among other know-how transfer projects to the US were the Beacon<br />
Hill Station Project, C170 in Seattle, Reach 5 for San Vicente Pipeline near San Diego and the Los<br />
Angeles Metro Gold Line Eastside Extension.<br />
