Almost everyone who walks sites now records something. Far fewer record anything they can use later.
The difference is rarely the camera. It is whether anyone was talking. A silent walkthrough is a pile of rooms you will have to identify again from memory. A narrated one is a record. Same phone, same ten minutes, completely different asset.
These are the habits that make the difference. None of them need software.
1. Say where you are before you say what you see
The single highest-value sentence on any walk is the one that locates you.
Level 3, unit 302, main bathroom.
Say it as you walk in, every time, before you start describing anything. It takes two seconds. Without it, every observation that follows is floating, and the person reassembling this later, which is usually you on a Thursday night, has to work backwards from the tiles to figure out which bathroom this was.
If the building has a reference system, use its words, not yours. Grid references, unit numbers, room names off the drawing. Your record should speak the same language as the documents it will end up next to.
2. Name the thing, then its condition, then your call
Three beats, in that order.
Architrave to the north window. Paint is flaking along the bottom edge. That is fair wear, no action.
The thing, the condition, the call. It sounds mechanical for about a day and then it becomes automatic. What it buys you is that every observation arrives complete. You are not left with “flaking here” attached to nothing.
The third beat matters most and gets dropped most. The condition is what anyone can see. The call is what you are being paid for.
3. Say the numbers out loud
Anything you measured, read, or counted goes in the audio.
Moisture meter reading 24% at the skirting, 12% a metre up the wall.
A photo of a meter is a photo of a meter, at an angle, in bad light, possibly of the wrong wall. The spoken number is unambiguous, it is timestamped, and it is searchable later. This is the highest-return habit on the list and it costs nothing.
Same for dimensions. If you are eyeballing it, say you are eyeballing it. “Roughly two metres” is honest and useful. A precise-sounding number you did not actually measure is neither.
4. Flag the action in the moment
When something is going to generate a line item, say so out loud, in the room.
That is an action. Smoke seal missing to the riser door, needs to go to the builder.
You will not remember which of the sixty things you looked at were the eight things that mattered. You think you will. You will not. Marking it at the moment of noticing is the only reliable method, and it turns the write-up from a re-reading exercise into a transcription one.
5. Narrate what is missing
Cameras record what is there. Only you notice what should be there and is not.
No handrail to this flight at all.
There is no damper where the duct crosses the compartment wall.
Absence is the most expert thing on any walk, and it is invisible to every form of automatic capture. If you say nothing, it is gone.
6. Close the room before you leave it
One sentence on the way out.
That is 302 done. Two actions, both in the bathroom.
This gives the record structure. It marks the boundary, it summarises, and it gives you a checkable count. When you are reconciling later and the bathroom has three actions against it, you know something drifted.
What not to do
Do not narrate the obvious. “This is a door. It is a white door.” You are not writing an inventory, you are adding what the camera cannot get.
Do not go quiet during the interesting part. It happens constantly. You find the real defect, you get absorbed in looking at it, and you stop talking for ninety seconds. That is exactly the ninety seconds you needed.
Do not save it up for the car. Notes dictated afterwards are memory, not record, and they lose the thing that makes narration valuable: it was said while you were looking at it.
Do not whisper. Site is loud. Speak up, and if there is plant running, either move or say it twice.
The point
Every one of these habits pays off with nothing but a phone and a folder. They make your own review faster, they make the record defensible, and they make it possible for someone else to pick up your walk and understand it.
They also happen to be exactly what makes a walkthrough legible to a machine, which is the part we care about. Sully reasons over the footage and the narration together, and a well-narrated walk produces a dramatically better draft than a silent one. But that is a side effect, not the reason.
The reason is that in six months you will not remember which bathroom it was.
