The site photograph that proves something: what has to be in frame

Most site photographs prove nothing, because they show the result and not the criterion. What has to be in the frame, why the date and position belong to the capture, and when a photograph cannot replace a test record.

There are eight hundred photographs of the job. In the argument about a fire collar that is now behind plasterboard, not one of them is any use, because none shows where it was taken or what the measured value was.

Taking photographs is not the hard part on a site. Proving something with them is.

What has to be in the frame

• The criterion, not just the result. For a bolt tension, the instrument with a readable value in the same frame as the bolt.
• Something that identifies the location: a grid line, a room number, a marked element. A close-up with no context proves that somewhere it looked like that.
• A second shot from further back, so the close-up can be placed in the building. It is nearly always the one that gets skipped and the one that matters when it is contested.
• Where the result is a fail, the requirement as well: the drawing number or specification clause departed from, readable or attached to the same check.

Date and position belong to the capture, not to memory

A photograph with no timestamp and no location cannot be placed in the sequence afterwards, and that is exactly what needs proving: that the state was that on that day, before the next layer went on. A folder of file names is not a chronology.

When a photograph is not enough

Where the criterion is a measured quantity that cannot be read off an image, a test record has to go with it: pressure against time, insulation resistance, level across a length. The photograph shows that the test happened and where; the record shows the result. Together they are evidence, and either alone is arguable.

Who signs off

Two roles, and not the same person: whoever does the work and whoever accepts it. At a hold point the release by the nominated party sits on top of that. An inspection signed off by the person who did the work is not worthless, but it weighs less at the moment it counts.

What the product does with it

In VariationFlow every inspection hangs off an ITP check with a photograph, a timestamp, a location and a result, and a check with no record stays open. Test records hang off the same check rather than a separate folder, so the evidence travels together into the handover pack.

Decision support, not legal advice. What form of record your contract requires comes from it and from the approved ITP.
