Contains guidelines for inspection of commercial HVAC duct systems for compliance with SMACNA/ANSI HVAC Duct Construction Standards—Metal and Flexible, (3rd Ed.) and Fibrous Glass Duct Construction Standards (7th Ed.). It reviews materials and reinforcement of duct systems, as well as assembly and supports of ducts. The Fire, Smoke and Radiation Damper Guide (5th Ed.) also summarizes installation details. Checklists are included for ductwork and fire dampers. Valuable as a study guide for the HVAC Duct Construction Standards manual and for learning inspection procedures in general. Includes soft metrics.
