These drilling works are object of this contract. The main objectives of these drilling works are to gather information about
• The depth of the rock line and
• The permeability of the rock mass.
Resulting from these purposes, un-cored drillings in the overburden, cored drillings in the hard rock, Lugeon testing in the hard rock, LeFranc-Maag testing in the overburden, grouting of boreholes, and installation of ground water piezometers for long-term water level measurment are planned as drilling works.
