What you'll learn
- Describe the scope, crew, sequence and coordination of a field duct installation job, and estimate crew hours from labor units
- Read HVAC duct plans, sections, schedules, specifications, shop drawings and RFI answers together, and check that a duct fits its space
- Lay out duct routes and hanger points from gridlines and benchmarks, set elevations with lasers and work out rod lengths
- Select hangers and supports, place them to the spacing rules, work out hanger loads and recognize when seismic bracing is required
- Choose and install cast-in inserts, post-installed anchors, beam clamps and other attachments, and apply edge, spacing and testing requirements
- Raise duct with lifts and hoists and work safely at heights from ladders, scaffolds and mobile elevating work platforms under the applicable rules
- Join, align and protect rectangular and round duct runs in the field, install takeoffs, and coordinate penetrations and insulation
- Install fire, smoke and combination dampers exactly to their listings, with sleeves, retaining angles, breakaway connections and access
- Seal duct to seal class A, set up and run leakage tests, calculate allowable leakage, find leaks and report results
- Connect duct to fans, air handlers, VAV boxes, terminals, flexible duct and louvers so the system can perform as designed
- Plan and carry out work in occupied buildings and hospitals with shutdown planning, dust and infection control and hazardous material precautions
- Install, inspect, test and hand over a complete duct run with its records, from coordination to closeout
