A variation register is a client's best document

On site, change is normal. Unpriced change is what destroys trust. Our rule is simple: nothing gets executed as a verbal instruction, and every variation is logged with a cost and time impact before it is built.

That register goes out weekly with the progress report and the photo log. The client watches cost move in real time instead of discovering it at final account.

It is not glamorous, and it is the single practice that has kept our contracts closing within a few percent of the agreed sum.
