A stone budget is not just material area × rate. It is a chain of costs that starts at the quarry, factory or distributor and ends at the finished surface on site.
1. Material
Record the stone type, thickness, format and quoted rate. For slab projects, note how many slabs are required and whether visual selection can affect yield.
2. Waste and yield
Rectangular rooms may still produce waste because of cuts, doors, columns, offsets, pattern requirements or slab dimensions. Your allowance should reflect the actual layout rather than a blind percentage.
3. Fabrication
Edges, cut-outs, polishing, sink openings, bevels, joints and other workshop work can be charged separately.
4. Logistics
Transport is not always a simple per-square-metre cost. Distance, vehicle type, loading, unloading, lifting and site access can matter.
5. Installation and substrate
Installation may depend on floor condition, level correction, adhesive, removal of old material, protection and the chosen method.
6. Taxes and commercial terms
Ask whether the quoted figures include applicable taxes and what payment, measurement and variation terms apply. The written quotation should define the scope.
