VERT / GREEN
Measurements use a documented method tied to the applicable product/drawing.
Flatness, level, plumb and square before finishes
Measure substrate before cabinetry, tile, glass, doors or panels; do not use a universal tolerance out of context.
JAUNE / YELLOW
A small framing error can become a large correction when rigid finishes arrive.
ROUGE / RED
If substrate exceeds product/spec/professional requirements, correct it before installation rather than forcing the finish.
Checkpoint before proceeding
What the professional checks
Finish trade and substrate-responsible party agree on measurement method and applicable criteria before installation.

Systems to check before closing the work
V14 connects envelope, air, fire, structure, water and code instead of treating each project in isolation.
V17
Specialized systems to cross-check
V17 completes gas, soil, water, fire, climate and structural interfaces.
V19
Edge systems to integrate into the project
V19 covers interfaces that become important when multiple home systems interact.
