As-built Verification

As-built verification provides accurate, independent confirmation that constructed assets have been delivered in line with design intent, tolerances, and specification.

What is as-built verification?

As-built verification is the process of surveying completed works to capture their true position, geometry, and condition, and comparing this data against design drawings or models. It creates a reliable, auditable record of what has actually been built on site.

This service is ideal for:

  • Validating construction works against design and contractual requirements
  • Identifying deviations early to reduce rework
  • Supporting project handover and final account sign-off
  • Providing trusted data for asset owners and operators
  • Infrastructure, utilities, aviation, rail, highways, and buildings projects
