                            The building site in Regjeringskvartalet, the Government Building Complex, consists mainly of alum shale and other black clay shales. In addition to the planning and follow-up of groundwork for tunnel and excavation pits for the new complex, NGI's work has included sampling, analysis and characterization of acidified rock masses.
