Safe gas supply for Stuttgart’s Vaihingen district

Just before Christmas it was done – 1,800m of gas pipelines DN 400 and DN 500 were laid and ready for action and all surfaces were restored as far as possible. The investment of the energy provider Netze BW in the pipeline network is supposed to safeguard the gas supply of Stuttgart in the future.

In October last year, the network construction division of Josef Rädlinger Ingenieurbau GmbH completed the first construction section of the new gas pipeline to be installed in the area of the highly frequented Pascalstraße in Stuttgart’s Vaihingen district. This was then followed by the start of the second, approx. 750m-long construction section. It ran parallel to the A831 motorway in the area of the Stuttgart motorway junction on a comparably less highly frequented road.

In addition to the actual service – the construction of a completely ready-for-operation gas high-pressure pipeline made from steel (pressure stage DP 70) –, further additional orders were received during the course of the construction measure. For example, an approx. 400m-long construction road was built for the maintenance of construction traffic and through traffic on the military training ground and then reconverted. Also approx. 4,800m of cable conduits and 800m of drainage pipelines were laid. However, all works ran as scheduled and were able to be completed to the utmost satisfaction of the client.

The integration of the newly laid pipeline into the existing Northern Black Forest pipeline network is scheduled for spring 2016 – by then, the network construction division will have completed all additional tasks. At the start of February, the construction of the new pressure regulator and measuring station will begin at the old Bernhardshöhe car park for hikers. Civil engineering works, clearing works and surface works are to be carried out by Rädlinger before the plant engineering division begins the structural engineering work for the system.
