Practical Notes

Highly useful for specification writers and quantity surveyors to maintain consistent terminology in BOQs (Bill of Quantities).

Helps prevent contractual disputes arising from ambiguous descriptions of architectural roofing components like eaves, flashing, ridge, and soffit.

BIM managers can use this terminology for naming conventions and parameter descriptions for roof families.
