Natural gas and oil, drinking and brackish water, acids and other chemical products are transported in pipelines.
Even though pipeline installation on land is not a big challenge, difficulties appear at the numerous intersections with streams and channels.
It is essential to design and construct these undercrossings in an absolutely reliable and maintenance-reduced way. In addition, the structures have to be completed in short time, in order to minimise the interference with the flow of traffic.
