The Inspection Sign-Off You Did Not Perform
You are a certified engineering technologist employed by a municipality. A contractor has installed a new watermain segment and, under the permit, needs an inspection sign-off before backfilling. You are assigned to inspect it, but on the scheduled day you are redirected to an emergency at another site. A colleague who is not certified drives past, looks at the open trench from the road for about two minutes, sees pipe in the ground, and texts you: "Looks fine, I'll sign the sheet for you, you're busy." The contractor is pressing to backfill before rain. The sign-off form has a single signature line and does not distinguish who inspected.
1. Can your colleague sign the sheet, and can you allow it?
Read the worked answer
No on both counts. The colleague did not perform an inspection; a two-minute view from the road cannot confirm bedding, jointing, alignment, grade, thrust restraint, or the depth of cover - the things the sign-off actually attests to. Allowing the colleague to sign "for you" would also make you the source of a false record, because the form implies the assigned inspector performed the inspection.
There is a certification dimension as well: if the sign-off is a regulated act reserved to a certified person or a person acting under a certified person's direction, the colleague may not be authorized to perform it at all. Even if the form does not say so, the substance of the attestation is technical and safety-relevant. The correct answer to the colleague is a clear no, with an explanation of what the sign-off covers, and a note to your supervisor that the form's design invites this problem.
2. The contractor needs to backfill before rain. What options do you have?
Read the worked answer
Options, in order of preference: (1) attend the site yourself, even briefly, and perform a real inspection of the items the sign-off covers before backfilling; (2) have another certified technologist who is competent in this work attend and inspect, with the sign-off made by that person in their own name; (3) if neither is possible before the rain, tell the contractor to hold backfill and protect the open trench, and give a specific time when inspection will occur.
What you cannot do is trade the inspection for the schedule. An uninspected watermain that is backfilled may have to be excavated later, and defects in bedding or jointing can fail months or years afterward with much greater cost and risk. Communicate the constraint to the contractor and your supervisor promptly so the decision is made with full information, not by default.
3. What should you do about the form design and the colleague's offer afterward?
Read the worked answer
Report both to your supervisor. The colleague's offer was well-intentioned but reflects a misunderstanding of what the sign-off means, so a short conversation about the purpose of inspection records is warranted, without making it a disciplinary matter unless it recurs. The form is the bigger issue: a single unnamed signature line lets anyone appear to have inspected, and it does not record time on site, items checked, or conditions. Propose that the form record the inspector's name, certification status, date and time of inspection, and a checklist of the items confirmed, with a note that the signer personally performed the inspection.
If the colleague or anyone else has already signed for inspections they did not perform, that is a records-integrity issue and must be escalated, not quietly corrected. Document your own actions and the reasons for them.
