Charismak Cost Planner
Material Quantity Estimate
Calculate practical procurement quantities across structural, architectural, finishing, MEP and specialist construction work. Every result states its basis, waste allowance and design limitations.
Select the material/work item
The fields change to match the material calculation.
Use the waste percentage to reflect breakage, cutting, laps and normal site losses. Adjust it to suit the material and site condition.
Quantity inputs

Enter the wet concrete volume and nominal mix. Use the engineer's design mix where specified.

Each option has its own quantity model.
Procurement quantities are rounded conservatively. Design-dependent items remain clearly labelled as planning allowances.
