The scope will include drilling of boreholes and installation of three main type of sensors: Piezometers, Inclinometers and Extensometers. The Subcontractors will be required to combine manual and automatic solutions, hence dataloggers will also to be installed within the boreholes to remotely record readings at agreed specified intervals.
