Offcuts and surplus stored at four sites and forgotten

Each project orders its own material with an allowance for waste. The allowance is usually generous, because running short mid-installation is worse than over-ordering.

Surplus has no home

What is left ends up in a van, a store or the site. It is not recorded, so the next project's order is placed as though it does not exist.

Offcuts are worth recording only if findable

A record of surplus with material and dimensions is usable. A pile in a corner is not, and it will be thrown away eventually to make space.

The allowance itself is worth checking

Comparing what was ordered with what was consumed, across projects, usually shows the waste allowance is set well above actual need — which is a straightforward saving requiring no change in practice beyond measuring.
