Site investigations for HDD crossing at Roskilde Fjord - LOT A

s with electrical resistivity mapping of the geology to identify shallow soft soil, low and high resistivity units between boreholes and homogeneity and fractureness of pre-quaternary soil units (Danien Chalk). Detailed seismic mapping down to at least 50 m under the seabed. Furthermore, the seabed

surface must be mapped with respect to water depth and surface characteristics. • Work Package B (Lot 2) - Geotechnical investigations with conventional geotechnical boreholes, CPT tests and laboratory tests, but also coreing of underlying
