01What is being requested

Rijkswaterstaat is seeking specialist advice in the field of soil and groundwater for remedial measures in the Prinses Margriettunnel. The procurement concerns an innovative drilling technique that operates at great depths without dewatering, but has led to unforeseen deformations that now require professional insight.

Rijkswaterstaat was confronted with an incident. At the Prinses Margriettunnel (PMT) on the A7 near Sneek, a tunnel section had heaved. Measures had been taken to stabilize the structure. In parallel, RWS, in cooperation with two market parties, has started the design and execution of the necessary remedial measures. In this process, a technique is being used in which new anchor piles are drilled to a depth of over 25 m against the water pressure. The technique used has not been used on this scale before, but is necessary to be able to work under the existing structure without dewatering. The
