🧩 What this command does
This command displays the Tile-Waste dialog box, allowing you to set or change the wastage factors for different tile items.
🔢 How tile wastage is calculated (sequence)
The tile wastage values are calculated in the following sequence:
The nett number of field tiles is first calculated.
Then the number of extra pieces per course is added.
Then the extra number of field pieces per length of hips and valleys is added (field pieces per metre or per foot of hip and valley).
Then the percentage waste of field pieces is added.
Then the total number of field pieces is rounded to give the final number.
Each waste value is applied in turn. If you do not want a particular waste factor to be applied, set the value to zero.
🧱 Extra Field Pieces (per course)
The first option — Extra Field Pieces (per course) — is a number or decimal fraction of a tile to add at the end of each course line to account for waste as a result of typical job variables such as breakages.
The more course lines there are, the more field pieces are added to the total tile count.
📏 Extra Field Pieces (per length of hip and valley)
Extra Field Pieces (per length of hip and valley) is applied based on the total combined length of hip and valley, and is expressed as pieces (or a decimal fraction of pieces) per metre (or foot) of hip and valley.
This is typically used to account for extra tiles that may be required as a result of breakages during cutting of tiles to fit at hips and valleys.
The more cuts there are, often the more breakages there are. No account is made for the re-use of the off-cut, as is sometimes possible with metal tiles.
If the off-cut is reused as a matter of course, then this needs to be taken into account and the number reduced.
Experiment with different values until you get the correct result based on your experience.
🧾 Other waste fields and Waste %
All other fields are individual values for each category of tile piece.
Waste % takes the total number calculated based on the course lines, adds the specified percentage, and then rounds up to the nearest value as specified.
A value of zero does not round up.
💾 Saving and loading configurations
Multiple configurations of tile wastage and rounding of elements can be specified and saved into various configuration files.
These files can now be linked to each tile record, allowing improved streamlining of waste and rounding calculation without requiring the estimator to remember to modify these values.
Select [Save-As] to save the tile waste file.
Select [Load] to load a previously defined set of values.
✅ Applying the values
When you click [OK], the values are saved.
These values are applied to the tile calculations when Reporting > Supply+Install is selected.
A summary of the tile waste calculations is then displayed when you select Tile-Waste from the Supply+Install or Supply-Only dialog box.
