Description

The scope of the SCPSS Framework has been split into three Lots to allow NWS to appoint the right specialist.

Lot 1 - Site Characterisation Planning and Technical Advisory Services: includes a wide range of consultancy, advisory, review and support services to NWS associated with all aspects of the planning, design, specification and delivery of site characterisation programmes (including onshore and offshore, intrusive and non-intrusive, plus off-site analysis).

Lot 2 - Geological and Geophysical Interpretation and Modelling: encompasses geological and geophysical analysis, interpretation and modelling activities required to support the development of geological understanding. This will include interpretation and modelling across multiple UK sites, regions and basins, reflecting evolving data availability, uncertainty, and project maturity.

Lot 3 - Hydrogeological Interpretation and Modelling: encompasses the research and technical development required to characterise, interpret and model hydrogeological and hydrogeochemical systems. This includes the development of conceptual and numerical groundwater flow and solute transport models.
