It involves a range of investigative activities, which will help NWS to inform assessments of the safety and suitability of sites.\nSite Characterisation enables a better understanding of the likely design and construction methodologies and therefore a higher certainty of the cost outturn. NWS must ensure they have knowledge and processes in place to meet requirements of design and safety case teams in line with regulations. \nThe scope is to provide professional services support for site characterisation activities across multiple sites. \nThe scope has been split into three Lots:\nLot 1: Site Characterisation Planning and Technical Advisory Services\nLot 2: Geological and Geophysical Interpretation and Modelling\nLot 3: Hydrogeological Interpretation and Modelling\nA pre-tender market engagement webinar on will take place at 15:00 on 14/09/2026.

This will include interpretation and modelling across multiple UK sites, regions and basins, reflecting evolving data availability, uncertainty, and project maturity.\nLot 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.\nITP and ITT documentation available on Atamis:  https://atamis-2464.my.site.com/s/Welcome",

This will include interpretation and modelling across multiple UK sites, regions and basins, reflecting evolving data availability, uncertainty, and project maturity.\nLot 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.\nITP and ITT documentation available on Atamis:  https://atamis-2464.my.site.com/s/Welcome",

This will include interpretation and modelling across multiple UK sites, regions and basins, reflecting evolving data availability, uncertainty, and project maturity.\nLot 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.\nITP and ITT documentation available on Atamis:  https://atamis-2464.my.site.com/s/Welcome",

It involves a range of investigative activities, which will help NWS to inform assessments of the safety and suitability of sites.\nSite Characterisation enables a better understanding of the likely design and construction methodologies and therefore a higher certainty of the cost outturn. NWS must ensure they have knowledge and processes in place to meet requirements of design and safety case teams in line with regulations. \nThe scope is to provide professional services support for site characterisation activities across multiple sites. \nThe scope has been split into three Lots:\nLot 1: Site Characterisation Planning and Technical Advisory Services\nLot 2: Geological and Geophysical Interpretation and Modelling\nLot 3: Hydrogeological Interpretation and Modelling\nA pre-tender market engagement webinar on will take place at 15:00 on 14/09/2026. Please use the link below to register for the webinar:\nNWS has also created a webpage to facilitate communication with the market and the sharing of documentation.

This will include interpretation and modelling across multiple UK sites, regions and basins, reflecting evolving data availability, uncertainty, and project maturity.\nLot 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.\nITP and ITT documentation available on Atamis:  https://atamis-2464.my.site.com/s/Welcome"
