ANDRA wishes to establish a framework agreement with purchase orders for geological monitoring services in galleries and associated works.

Mobilization and installation of equipment and teams on site; The acquisition of geological data, which includes:-The geological and structural survey of the walls of the galleries (between 150 and 200 over 4 years), including: -The shooting of the walls for the geological monitoring of the galleries;-The topographical survey of the face and the walls raised;-The establishment of restitution of wall surveys;-The survey of traces of oxidation.-The geological and structural survey of the boreholes (cores) (approx. 500 boreholes for 5000 ml of cores: order of magnitude over 4 years), comprising:-The realization and exploitation of instantaneous and delayed logs (gamma-ray, diameter, ...) , and endoscope for the geological monitoring of boreholes (equipment provided by Andra) (approx. 200-300); -The photography of cores for the monitoring of boreholes;-The establishment of restitution of geological logs;-The recording of traces of oxidation;-The completion of Excel sheets allowing the update of the database of samples of Andra.-On-site measurement of water contents by heating to 105°C (standard NF ISO11465) and 150°C, calcidolomimetrics;-Systematic sampling, conditioning of geological and geochemical samples for subsequent laboratory analysis.-Installation of convergence measurement sections, and their periodic measurements (equipment provided by Andra except the studs);-Site and/or coordination meetings, with Andra and with other service providers;-The preparation and publication of the monthly measurement report (RDM) for roadway surveys or drilling as well as the provision of the corresponding numerical data (Excel sheets, log in Wellcad format, etc.). Throughout the duration of the service, the Account Holder must keep up to date the list of authorizations of all its current or future staff (additional persons to intervene during the contract), and verify the validity of individual access on site; and safety training (safety instructions and the wearing of APEVA - autonomous breathing system, use of emergency niches) to access the bottom.
