🧾 What it does
The Tile-Waste dialog box allows you to set or change the wastage factors for different tile items. These factors are automatically applied to tile calculations when generating supply and installation reports, ensuring accurate material quantities without requiring estimators to manually adjust values for each job.
🔧 How the calculation sequence works
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 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.
🛠 Waste factor settings
Field | Description |
Extra Field Pieces (per course) | Number or decimal fraction of a tile to add at the end of each course line to account for waste from typical job variables such as breakages. The more course lines, the more field pieces added to the total tile count. |
Extra Field Pieces (per length of hip and valley) | Applied based on the total length of hip and valley combined, expressed as pieces or decimal fraction of pieces per metre (or foot) of hip and valley. Accounts for extra tiles required due to breakages during cutting of tiles to fit at hips and valleys. |
Waste % | Takes the total number calculated based on course lines and adds the specified percentage, then rounds up to the nearest value as specified. A waste percentage of zero adds no waste and performs no rounding. |
💡 Hip and valley considerations
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.
🔧 Configuration file management
Multiple configurations of tile wastage and rounding of elements can be specified and saved into various configuration files. These files can 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 settings
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.
