As-built plans
As-built plans should:
- Clearly illustrate what has changed compared to the original plan, so that the proposed changes can be verified and technically approved prior to a supplemental agreement.
- Be based on an updated detailed topographical survey, rather than a relabelled agreement plan or Ordnance Survey based plan.
- Be supplied as soon as is feasible before the provisional certificate of completion.
Supplemental agreements
Where required, supplemental agreements should:
- Include a plan illustrating what has changed against the original plan.
- Include a plan illustrating what has changed against the as-built plan.
- Illustrate any change in assets to be adopted because of the change.
