Optimizing B2B Natural Stone Procurement
Procuring stone for multi-million dollar architectural projects demands structured Bill of Quantities (BOQ) specifications, strict dimensional tolerances, and clear third-party factory inspection protocols.
Essential BOQ Parameters
- Material Grade & Quarry Origin: Exact commercial trade name, block selection grade (Grade A/B), and origin region.
- Dimensional Tolerances: Length & Width ±1mm, Thickness ±1mm, Diagonal Deviation ≤1.5mm.
- Surface Finish Definition: Polished (85+ gloss units), Honed, Flamed, Bush-Hammered, Waterjet, or Antique/Leathered.
- Dry-Lay Inspection: Pre-shipment dry-lay layout in factory to approve color harmony, grain transition, and shade variation.
