To help you ensure accuracy, 4 separate stages of checking are built into the process of completing a project within Countfire.
- Hiding matched symbols in-app.
- Record drawing review
- Symbols removed drawing review.
- Check sheet review
The above checks should be performed in the order listed.
Stage 1: Hiding matched symbols in-app
Stage 1 is a workflow for checking drawings as you complete them and involves hiding the symbols you have already counted, and then scanning over the drawing to check you haven’t missed anything.
It can be helpful to perform this check with the background shown, and then again with it hidden.
In the clip above, you can see symbols that have already been counted are toggled off (Shortcut = T), and then a quick check of the drawing is done. Then, the background is turned off (Shortcut = B), and another check is done.
Stages 2 & 3: Record & symbols removed drawing review
Checking stages 2 & 3 can be performed at the same time and involve scanning the output drawings to check whether any symbols have been missed or mistakes made.
In the clip above, you can see both the record drawings and symbols removed drawings are opened, and then methodically reviewed in turn.
The symbols removed drawings, in particular, make it obvious if a symbol has been missed.

Stage 4: Check sheet review
Before a take-off can be said to be complete within Countfire, and the numbers relied upon, it’s essential to review the check sheet for each discipline on your project.
Reviewing a check sheet involves scanning down the categorised list of symbols, taking care to spot any false positives or selections made under the wrong symbol descriptions, and then making any corrections needed.
In the clip above, the check sheet is quickly scanned and all the “Switches” and “Type B” symbols are verified to be correct.
However, an “LCM” symbol is also shown counted under the “Type BE” heading, and this needs to be corrected.
