Utility lines in circulating traffic.

A main sewer in the City of Linz was commissioned by Erste ÖSW Wohnbauträger GmbH. The project included partial contracts for in-situ concrete connections to the existing system and linkage of a secondary collector. PORR was responsible for all the earthworks, master builder and pipe-laying work.

A giant slide rail shoring system was used to lay the pipes into trenches excavated up to 6m deep. A particular challenge arose due to the requirement that traffic should continue to circulate normally throughout the construction period. The PORR team was able to complete the challenging utility lines project in a mere six-week construction period.
