Pre- and Post-Construction Surveys: Evidence-Based O&M for Road Contractors

For contractors managing Operations & Maintenance (O&M) contracts, the dispute that matters most is usually “was this defect already there before we started, or did it happen on our watch?” A pre-construction survey creates a timestamped, geo-tagged baseline before work begins; a post-construction survey documents the same stretch afterward — giving both the contractor and the authority an objective record rather than a disputed claim.

This same evidence trail supports quality assurance during the contract period too: periodic surveys through the O&M term flag emerging defects early, before they become expensive disputes at handover.
