       Improvement Plan
           1.  Continue with cyclical maintenance inspections across roads and carpark infrastructure with results and overall
               asset condition (based on the core asset management approach) recorded in the asset system;
          2.   Reconcile financial asset data, GIS data and Inspection data to ensure a single point of truth for asset data
              within the asset system;
          3.   Develop a long term asset replacement programme integrated with financial planning and asset deterioration
               modelling;
          4.   Produce ‘next generation’ Asset Management Plans at a lower level of asset class hierarchy, for example

-         5. Further develop the Pavement Management System to improve the level of confidence in reseal and
               rehabilitation programmes.
