The tool for design-driven, spec-tight projects: consistent colour and pattern at scale, engineered performance, and program pricing across thousands of units. Quartz and granite are grouped by price tier, so a change of material does not mean a change of program. Slabs shown true to material - no colour grading.
Both books are sourced and priced against the same group structure, and the silica-free lane sits behind them on the same terms. If the owner changes the spec, the program carries over instead of starting again.
