Tenders Are Invited For Ground Investigation Work – Framework Agreement For Geotechnical Investigations >400 ... in France

Work Detail

Ground Investigation Work – Framework Agreement For Geotechnical Investigations >400M - New Line Alpins Access. The Multi-Awardee Framework Agreement Which Is The Subject Of This Estimate Note Concerns The Carrying Out Of Surveys At Very Great Depths (More Than 400M), With The Aim Of Obtaining The Data Necessary For The Drafting Of The Geological, Hydrogeological And Geotechnical Summary Reports For The Chartreuse, Belledonne And Glandon Tunnels, Then Depending On The Available Budget, Acquiring New Data To Resolve The Uncertainties Identified Following The Drafting Of These Summary Reports. Works Concerned: Chartreuse, Belledonne And Glandon Tunnels Data Sought: Geological, Hydrogeological, Geotechnical Characteristics And Characterization Of Excavated Materials With A View To Their Use (Physico-Chemical Characterization And Management Pathways). Specificities Of The Investigations: • Vertical And Inclined Drilling With A Depth Of 400 To 1500M • Type Of Drilling: Core Drilling, With Part Of The Drilling Carried Out Destructively • Instrumentation: Pore Pressure Cells, Etc. • In Situ Tests: Logs, Water Tests, Dilatometric Tests, Stress Measurements, Etc. • Laboratory Tests For Geotechnical, Hydrogeological Characterization And Use Of Matex
