VRS: Survey & Renewal

Vehicle Restraint System surveys and renewals, with the same accuracy as our drainage work.

Surveys
Detection & Remediation

We apply the same accuracy and diligence to Vehicle Restraint Systems that defines our drainage survey work, whether you need a VRS condition survey to inform design, or a renewal project delivered end to end.

Our VRS Surveys deliver dependable asset data that de-risks every design and scheme that follows, and because we’re not a large organisation weighed down by inter-departmental process, we can move quickly.

For clients needing full VRS renewal, we deliver barrier and parapet replacement through an accredited hybrid model: NHSS Scheme 10B-accredited installation teams (10B incorporates Schemes 2B and 5B) working under our own management and quality systems.

Why DDC?

As a fully accredited Principal Contractor, we coordinate and self-deliver every aspect including roadspace booking, traffic management, vegetation clearance, GPR, topographical surveys and confined space entry, so when we arrive on site, there’s nothing standing between us and the project.

Services include

  • VRS condition surveys, defect identification and structural testing across mainline, slip roads, central reserve and structures
  • Post and foundation testing, ground-penetrating radar and buried-services investigation
  • Structured survey and test data for scheme design and the Road Restraint Risk Assessment Process
  • Barrier, terminal, crash-cushion and parapet replacement via NHSS 10B-accredited teams (incorporating 2B & 5B)
