A worked example
Answers used: Doors to hang 2 nr; New door linings / frames too? no; Door type solid core; Remove existing doors? yes. These are the recipe's own quantities for those answers - the prices are yours, the supplier's or a quotation's, never a figure typed on a web page.
| Kind | Line | Quantity | How it is worked out |
|---|---|---|---|
| material | Solid-core door | 2 nr 2 x nr - each | 2 doors |
| material | Hinges (3 per door), latch, handles, door stop | 2 nr 2 x nr - set per door | 2 sets |
| labour | Hang doors | 4 hr | 2 x 2 h |
| waste | Old doors / linings to dispose | 0.16 m3 | 2 x 0.08 m3 |
Labour on this example: about 4 hours across the roles; at your rates it becomes money.
