Build Over Drain survey in Staffordshire

Build over drain survey carried out for a residential property to enable build over approval and final sign-off of their extension near a shared line.

Location: Stoke-on-Trent, Staffordshire
Service: Build over drain survey

Overview

We were instructed by a homeowner to carry out a build over drain survey ahead of a proposed extension within 3 metres of a shared drainage line.

Upon completion of the foundations and slab, a post-build survey was conducted to verify that the construction works had not caused any damage to the shared drainage network.

What we did

We carried out a full inspection of the drainage system in the vicinity of the proposed extension, including the shared line.

Our report included

  • Assessment of condition and identification of any defects

  • HD photos and videos to support our assessment

  • Annotated map of the site, overlaid with the drainage network pre- and post- construction

  • Key findings and our recommendations

What we found

Our pre-build drainage survey identified existing fractures and root ingress within the shared line, which were clearly communicated to the homeowner prior to construction.

A post-build survey was subsequently carried out to verify that:

  • The existing defects had not worsened; and

  • No additional damage had been caused to the remainder of the shared drainage network during the construction works.

Outcome

The pre-construction survey was submitted to the water authority to allow our client to move ahead with his build, with the post-construction survey allowing him to obtain final sign-off from the water authority.

A relatively straightforward case, but a strong example of how early identification, clear communication, and robust verification can ensure a smooth approval process.
