Why it matters

When the dispute arrives, the question is always: what did you have in place and when? This document is the answer.

What it's for

Once a trench is backfilled, the pipe’s line, level, bedding and joints cannot be seen without digging it up again. A signed pre-backfill inspection is the record that the work was checked against the drawing and specification while it was still visible, and that it passed its tests.

When you need it

Before backfilling each pipe run, typically from manhole to manhole, after the pipe has been laid, jointed and tested.

Who signs it

The person carrying out the inspection, and the client or engineer accepting it. The declaration confirms whether the pipework is ready for backfilling.

What's inside

  • Project, inspection number, pipe run, drawing reference, diameter and material
  • Excavation checks: support, trench bottom, sides, access and edge protection
  • Pipework checks: line, level and fall, pipe class, joints, connections and rocker pipes
  • Bedding and surround checks against the specification
  • A manhole and chamber table
  • Test results for air, water and CCTV, with record references, plus a photo reference
  • A declaration and sign-off

FAQ

Which tests does it record?
Air or water tests to BS EN 1610, and a CCTV survey where required, each with a reference to the full test record.
Should I take photos?
Yes. Photos of the pipe, bedding and joints before backfilling are strong evidence. The checklist has a space for photo references.
What if something fails?
Do not backfill. Record the problem, correct it and inspect again.
Should the person who laid the pipe inspect it?
It is better if someone else carries out the inspection, with the client or engineer accepting it. The checklist has separate signatures for the inspection and the acceptance.
What is [TO CONFIRM]?
Details only you know, such as references, names and locations. We never guess these. They appear as highlighted [TO CONFIRM] placeholders, and the inspection record opens with a list of every one. Results, readings, dates and signatures are left blank for completion at the time.
Can I edit the document?
Yes. Both options are Word documents you can edit freely.
Do I still need to review it?
Yes. A competent person must check every document against the actual site and works before it is used. ClarusDocs gives you a complete first draft, not a substitute for that check.
