Rob Smith’s Member Highway Service Update of 27th January said.... “Still busy dealing with the impact of the wet weather

  • The exceptional weather over Christmas and early January is now behind

us, it has resulted in a higher number of highway faults than the seasonal average.

  • Teams that normally delivery Category 2 works and our minor HLB

schemes have had to focus their efforts on fixing the high number of highway faults, keeping our highways safe. Potholes - improving repair policy – You said, we did

  • Our recently launched Defect Management Approach means that more

potholes are now repaired permanently first time. This has shown a corresponding reduction in failures of temporary repairs.”

How we have coped

  • Additional Staff providing cover Operations Hub at nights and

weekends

  • Additional Gangs have been working nights and weekends to

respond to the call outs

  • Teams that normally delivery Category 2 works and our minor

HLB schemes have been diverted to keeping our highways safe

  • Drainage crews focused on EA highlighted “areas of risk”

Catching up post emergencies

  • The Emergency Protocol

– KPI suspension – Local Control

  • Recovery actions

– Four road sweeper vehicles are being utilised to clear debris where floods have dissipated – Permanent pothole repair catch up – Large scale resurfacing programmes (re-allocating crews)

The new Defect Management Approach

Defect Types

  • ‘Emergency’ – is a Defect that requires very prompt attention

because they represent an immediate or imminent risk

  • ‘Category 1 Defects’ - are Defects that require prompt

attention because they represent an immediate or imminent risk

  • ‘Category 2 Defects’ are all Defects that are not categorised as

Category 1 Defects

Information requested Response Choice Where is the pot hole? (Mandatory) Road Cycle Lane What is the depth? Please provide your best estimate (Mandatory) Less than 40mm / 1 ½ inch 40mm / 1 ½ inch – 100mm / 3 inch More than 100mm / 3 inch What is the width? Please provide your best estimate (Mandatory) Less than 300mm / 12 inch / 1 foot More than 300mm / 12 inch / 1 foot
