WNA Berlin is planning to replace the new Marggraff Bridge, which consists of three partial bridges. It will be replaced by a two-part new building. At the same time, the bank pile wall in the bridge area is being renewed.

Shipping and road traffic must be maintained during the construction project. In the construction phase, one of the three sub-bridges will be upgraded for road traffic. As there are several lines from different line operators within the construction field, it is necessary to lay them in advance of the bridge construction work. This requires traffic safety services that have to be adapted several times to the progress of construction.

Services to be performed:

Relocation of pipelines (water, district heating, gas, electricity, communication lines), including civil engineering

bridge construction

Technical processing (among others):

- Provide execution planning including static calculation (building aid, demolition and new construction)

- Deliver technical planning (traffic facilities)

- Create road signs and marking plans

- Deliver inventory documents and drawings

- Record building data, create building book

- Deliver a measurement program for the engineering survey of the building

- Coordination of pension providers
