    Quality and safety in construction
    is priority at LEONHARD WEISS
    General contractor network construction

Bahnhof Bamberg

Customer: DB Netz AG
Construction period: 2 months Year of construction: 2021
Particularities: As general contractor LEONHARD WEISS took over the responsibility for execution planning, BIM coordination, as well as the construction of respectively 30 m platform extension at the station Bamberg. Platform works, underground cable engineering, drainage works, superstructure works, and equipment works were realised during a very short period of time. Both platforms made of prefabricated parts, were constructed with new railings, new signposting, extended sound engineering, was well as adapted overhead line facility.


BIM project to prove the practicability of the BIM method. Building models were created and combined with subject-specific models (overhead line facility, control, communication, and safety system). The data and information (routes, trades, locations etc.) were digitally recorded, processed, and combined to form BIM objects. After successful 3D-modelling, schedule planning and the service specifications were linked with the 3D-model.

Breisgau suburban railway 2020 section Höllentalbahn West

New transport depots for Germany’s steepest railway

Customer: DB Netz AG, Karlsruhe
Construction period: 8 months Year of construction: 2018
Thanks to the complete shutdown of the lines 4300 and 4301 from Freiburg main station to Titisee and station Bärental the construction measure could be realised within only 6 months. During this time simultaneous works on overhead lines, point heating, superstructure could be carried out. Passages and rock consolidations could be newly built. Due to the fact, that the lines partly have only one track, track-bound vehicles were equipped with a tracker, which makes it possible to locate the equipment on the construction site and coordinate it accordingly.

What was constructed

New construction transport depot Himmelreich incl. lighting system, new construction transport deport Hinterzarten and Titisee incl. lighting system and two elevator pits. New construction of points at the station Himmelreich, station Hirschsprung incl. formation and deep drain. Underground cable engineering from km 12.5 to 34.0 with a total of 12 special foundations for signalling technology, laying of cables for control, communication and safety system from km 12.5 to 34.0, laying of cables for telecommunication from km 12.5 to 34.0.
