Too Close! Proximity rules for Reinstatement - 300mm, 250mm and 150mm rule
Failing to cut back to avoid proximity failures costs time and money to rectify and means we must revisit sites adding to the potential risk and disruption to the highway network.
- 150mm rule: For all footways, footpaths and cycle tracks, where trim-lines for the reinstatement edges are within 150mm of an edge, kerb, ironwork or other reinstatements, the trim-lines must be extended to the interface of the edge, kerb etc. You must cut back.
- 250mm rule: Where the trimmed edge of any excavation in a flexible or composite carriageway is within 250mm of the road edge, kerbing, other fixed features or another reinstatement, the trim-line must be extended to the interface with the road edge, kerbing etc. You must cut back.
- 300mm rule: The edge of the excavation in a concrete carriageway must not be located within 300mm of a kerb, ironwork, transverse or longitudinal joints or another reinstatement unless the trim-line and surface reinstatement can be extended up to the feature in question. You must cut back.
HOW TO ENSURE COMPLIANCE:
Ensure all above rules are adhered to. Any additional trim back required can be restricted to the surface course only. If in doubt, take it out and/or ask your supervisor or other competent person.
If the actions above are adhered to then this will assist in reducing reinstatement failures. Everyone has an active responsibility in ensuring operational activities are completed to the required quality standards
