- Change The contract was amended to increase the implementation phase cost by £109,983.37. Delivery dates for final milestones were revised, and certain functional requirements were updated following completion of the MVP stage. Elements no longer required for the implementation phase were removed, while others were replaced to reflect technological developments and improved user benefits. Enhanced security requirements were also introduced. The overall scope of the contracted solution remain unchanged, Need for additional works, services or supplies by the original contractor/concessionaire: The modification arose from circumstances identified after contract award during implementation. Following novation to Node4 Limited, delivery complexity exceeded that anticipated at award, creating a material and unforeseeable risk to delivery continuity. To mitigate this risk, delivery arrangements and funding were adjusted. Post‐MVP requirement refinements and enhanced security led to milestone changes and a cost increase of £109,623.37. The changes do not alter the contract’s scope.
