Enabling enhanced capture productivity and safety
600 metres of tunnel scanned safely in 40 minutes
PROJECT: Fast and safe kinematic reality capture in Elbe Tunnel, Germany
CUSTOMER: dhp:i
PRODUCT: Leica ProScan
OBJECTIVE: Documentation the three older tunnel tubes by kinematic 3D laser scanning to create current, accurate inventory documentation available to the Elbe Tunnel operator.
One of the most important components of northern Europe’s infrastructure lies about 28 metres (92 feet) below the surface of the Elbe River: the Elbe Tunnel in Hamburg. As part of the A7 Autobahn, it connects the southern and northern portions of the Hanseatic city of Hamburg and the Scandinavian countries with Europe’s metropolises. It is about 3.3 kilometres (1.9 miles) in length, with some 1,000 metres (3,280 feet) passing under the riverbed. At peak periods, up to 145,000 cars and trucks pass through the tunnel’s four tubes each day.
The three older tunnel tubes were captured by kinematic 3D laser scanning to create current, accurate inventory documentation for the Elbe Tunnel operator. Previously unachievable without considerable disruption, Leica ProScan enabled the rapid and accurate mapping of the underground environment within tight overnight access restrictions.
Enabling accurate inventory documentation
The objective was to make current, accurate inventory documentation available to the Elbe Tunnel operator. The georeferenced information obtained will be needed for maintenance and repair support of Elbe Tunnel planning, design, construction and administration processes and as a basis for future Building Information Modelling (BIM), among other uses.
Enabling efficient asset collection
In addition to the tunnel geometry, all other objects and equipment in the tunnel also had to be recorded for this purpose within an accuracy of a few centimetres. The assets included emergency exits, phones and operation alcoves, escape route signage, fire protection systems, ventilation shafts, lighting systems, cameras, amongst others, totalling more than 200 different 3D objects.
