Case 1 — second opinion on a fire strategy
A loft conversion's fire strategy was queried by the local authority. The builder asked for an independent review before committing to remedial work. Half the queries were resolved on the drawings; the other half saved by a small change to door specifications.
Case 2 — caught a misread drawing pre-pour
A builder asked for a foundation walk before pour. A drawing revision had specified a 200mm deeper trench in one bay. Caught with twenty minutes to spare.
Case 3 — handover audit before final invoice
A builder used an independent audit to prove their work was complete and compliant before issuing the final invoice. The homeowner paid promptly. Everyone won.
