How to use this result
Use this to assemble an early complete-project allowance before formal design and proposals.

Existing buildings
Hidden shafts, roof conditions and occupied-space work can materially change the project.
Important: Commercial kitchen exhaust, makeup air, grease ducts, cooking appliances, gas systems, fire suppression, roof work, electrical work, food-premises requirements and cleaning obligations vary by country, province or state, municipality, building, appliance duty and adopted code edition. Qualified local professionals and the authority having jurisdiction must determine the required system, airflow, clearances, interlocks, fire protection, cleaning schedule and approvals.
