Survey before the price, not after
Here we did, which is why the twelve drawings existed before cutting.
If skippedQuoting from the structural drawing would have priced twelve identical parts and built twelve wrong ones.
12 lift sets
against concrete
18 mm out of position
Twelve openings became twelve drawings. That decision is the only reason the job needed one shim instead of twenty-eight.

01
The job
Twelve lift openings across six floors, each needing a three-sided surround, a reveal and front panels. Brushed finish.
The structural openings were built by another trade, to their tolerance. Ours had to be tighter, because a surround is a straight line drawn against a wall that is not.
Why it is a case file
Because twelve openings became twelve drawings, and that decision is the only reason the job needed one shim on site instead of twenty-eight.

The record
- Brief
- Twelve lift openings, six floors, brushed stainless surrounds and front panels.
- Survey
- Four measurements per opening: width, height, plumb, wall thickness. Deviation up to 18 mm against the structural drawing.
- Drawings
- One drawing per opening, not per type. Twelve drawings, twelve sizes.
- Reveal
- Return width set from the measured wall thickness, so the shadow line stayed constant on every floor.
- Assembly
- Three-sided surrounds joined and squared on our floor before packing — the corner is a made joint, not a site joint.
- On site
- One shim used, on opening 7, where the floor level was 3 mm high. No site cuts.
- Delay
- None.
Figures in this record are being confirmed with the client before publication and are marked in the drawing set. We publish a case file only when the numbers can be checked — a wrong job record is a factual error, not a typo.

What we would do differently
Draw per opening, never per type
Twelve drawings cost more office time and saved the whole job.
If skippedA drawing per type means eleven openings get packed out differently, and the packing-out is where the shadow gap goes wrong.
Fix the reveal width after measuring
The return was cut once, from measured wall thickness.
If skippedCut at nominal, the shadow line tapers from 5 mm at the bottom to 12 mm at the top of the same door.
