For the foundation CCI Leidingsystemen delivered 2 steel pipelines DN700 with PP-coating and cement lining for drinking water.
Because of the height restrictions by Airport Schiphol, because of the air traffic around the working location, we had to work with a smaller curve radius then customary.
In consultation with CCI Leidingsystemen the drilling has been performed with a curve radius of 650 x D. Normally we work with a radius of 1000 x D with cement lining.
