HVAC Estimating Services
SMACNA sheet metal weight takeoffs, rooftop units, VAV boxes, VRF heat recovery, HRV/ERV ventilation, cold-climate heat pumps, kitchen and lab exhaust, and TAB allowances for HVAC contractors.
Technical Takeoff Scope & Engineering Overview
Sheet metal margins depend on SMACNA pressure-class gauges, fitting ratios, fire and smoke damper framing and crane picks. We convert rectangular, spiral and oval duct to galvanized, stainless or aluminum weight plus liner and wrap, and size HRV/ERV and heat-pump equipment for Canadian heating degree days.
Governing Canadian Codes & Specifications
- SMACNA duct construction standards
- CSA B52 mechanical refrigeration code
- ASHRAE 62.1 ventilation
- NECB energy requirements
