Highways Infrastructure Asset Management Plan (HIAMP) Page 153 Agenda Item 6 Code of Practice Revision
Lincolnshire Highways Asset Management Key Documents Highways Asset Management Policy Page 154 Highways Asset Management Strategy Highways Asset Management Plan
Background to the HIAMP • “Well Maintained Highways” – Code of Practice (July 2005) • Prescriptive document • “Highways Maintenance Plan” prior to 2015 Page 155 • 2015 review produced Highways Asset Management Plan to align with Policy and Strategy • New Code of Practice “Well Managed Highway Infrastructure” introduced in October 2016
Review • Adjusting the Highways Asset Management Plan to match Central government requests and maintain Local Best practice Page 156 – Align to DfT funding streams – Full Risk based approach (where appropriate) – Legal Relevance and Repercussions – Full Risk based approach (where appropriate)
Priority Areas Adoption of a Risk-Based Approach Page 157 Consistency A Network with Other Hierarchy Authorities Review Engagement and Communication with Stakeholders
Code of Practice Structure • Overarching Principles • Highways Page 158 • Structures • Street Lighting
Risk-based Approach • The management of current and future risks associated with assets should be embedded within the approach to asset management. Page 159 Strategic, tactical and operational risks should be included as should appropriate mitigation measures (HIAMG Recommendation 11 - Risk Management). • ‘Prevention is better than Cure’
Hierarchy Review Current Carriageway Hierarchies • Hierarchy 1 - some of the busiest A roads Page 160 • Hierarchy 2 - some A roads, some B roads • Hierarchy 3 - some B roads, some C roads • Hierarchy 4/5 - some C roads, all unclassified roads
Hierarchy Review Proposed new Hierarchies LCC Local Standard National Standard Major Road Network Strategic Route Hierarchy 1 Strategic Route Page 161 Hierarchy 2 Main Distributor Hierarchy 3 Secondary Distributor Hierarchy 4 Link Roads Hierarchy 5 Link Roads Hierarchy 6 Local Access Road Hierarchy 7 Minor Roads Hierarchy 8 Minor Roads
Hierarchy Review • Base of our defect repair regime and our inspection Page 162 regime • Align to a risk-based approach • Major Route Network
