Site Characterisation is the process of developing a detailed understanding of the geology and surrounding environment of an area. It involves a range of investigative activities, which will help NWS to inform assessments of the safety and suitability of sites. Site 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. The scope is to provide professional services support for site characterisation activities across multiple sites. The scope has been split into three

Lots
