KEY RISKS/CHALLENGES

• Considerable vehicular traffic off the A168 accessing the nearby business estate, so disruption had to be kept to a minimum with Traffic Management planned to prevent tailbacks onto the A168
• The road area was within a flood plain so works that could have been affected by flooding were programmed early with sufficient time / risk allowance to minimise disruption if flooding occurred

LESSONS IMPLEMENTED, COLLABORATION AND VALUE ADDED

• Pipe bursting was value engineered and substituted with pipe liner to provide financial saving to the client and to speed up the works
• In-house surfacing gangs on hand to maintain flexibility and programme
• Significant planning undertaken with quarries and haulage contractors to ensure that they could supply materials for the one week road closure works
• Our bespoke commercial tracker for Compensation Events /Early Warnings/Project Manager Instructions was utilised to ensure key dates were achieved and to provide cost certainty for our client
• Liaison with local farmers to ensure that access was maintained at crucial times for them
• Stockpiling of materials to minimise disruption from potential unavailability of materials

‍

PLANNING AND PROGRAMME

• Weekend working was implemented for planning, tarmac and white lining operations to minimise disruption as the road was considerably quieter at the weekends
• A full road closure for final surfacing works and lining was set for the October half term, this road closure could not be altered  

‍

SUCCESSFUL OUTCOMES

• The window for the one week road closure period was achieved
• Traffic flows maintained with minimum disruption to road users
• No accidents or incidents with the general public
