Through every build we run a photographic record with geo-location and timestamp. It supports SAP report population, Build warranty evidencing, Building Control inspections and the future owner’s information pack.

Should anything need to be challenged later — a hidden detail of the build, a sequence of events, a question about what was installed where — the record gives a clear, defensible answer.

It’s a small discipline that pays out only occasionally. When it pays out, it pays out heavily.
