Norfolk County Council procedures are followed to recognise projects that have such potential and monitor risks at Corporate and Departmental level. The risks managed at Departmental level are monitored on a monthly basis and scored as either: R - poor progress needs escalation, B - some progress needs some review, or G - good progress/ on schedule. If a risk is 'scored' as R then it needs to be escalated to the Corporate level. The allocation of risk, is based on the principle that risk is placed with the party best placed to manage or mitigate that risk should it transpire. NCC has drawn up a detailed risk register for both components for the CIF project, which can be found in Appendix 4C. In the case of the Park & Ride scheme, our strategic partners, who will be responsible for design and delivery, have been fully involved in the preparation of the risk register, with responsibilities designated accordingly. For Postwick Junction, NCC has developed its own quantified risk register, but following appointment, the preferred contractor will become part of the team and work with NCC to update and maintain the quantified risk register. Decisions will then be made on the risk share mechanism between the contractor and NCC to ensure that the proposed allocation provides value for money to the Council. Stakeholder Analysis The County Council recognises the necessity for successful interaction with the wide range of stakeholders and the involvement of the surrounding community throughout the before and throughout project implementation. Section 4.6 of this document identifies various stakeholder interests, highlights consultation already undertaken and future engagement plans.
