Market Engagement
The purpose of this webpage is to facilitate communication and relevant document sharing between NWS and prospective suppliers in advance of the upcoming tender. It forms part of an ongoing market engagement process. For the latest documents please refer to the below section ‘Supplier Documentation’.
In addition there will be other market engagement activities conducted to share principles of our procurement strategy and draft ITT documentation. The feedback received will enable us to incorporate valuable input into the final tender documents and help the market get a clearer understanding of the project, scope and commercial requirements.
The SCPSS will bridge the gap between a number of existing frameworks and contracts which will end prior to the Site Characterisation Delivery Partner (SCDP) coming on board. NWS do not currently foresee any conflict of interest between the SCPSS and the SCDP.
