Construction model comprising data of different sources, Rosshaupten Dam, Germany.
Ahead of the pr-treatment grouting works, seven exploratory boreholes were drilled, to a depth of up to 85 m, in order to take cores, and to obtain supplementary information about the unconﬁ ned compressive strength, the fracturing degree and the permeability of the existing rock. The per-meability was determined using the Lugeon packer test.
The data, which was monitored during all drilling works, also gave valuable information for the later grab and cutter excavation for the trenching. The data were digitalized and a 3D model and was produced step by step in real time, documentation and vizualization using Bauer’s specialist digitization B-project model.
