Frequently asked questions
What is CSI Division 23?
HVAC — air handling, ductwork, hydronics, refrigeration, exhaust, and HVAC controls.
Why are HVAC controls a margin risk?
BAS integration scope is often vague — clarify what's mechanical-furnished vs. low-voltage scope before bid day.
Can BidEngine help HVAC contractors?
Yes — it pulls equipment schedules, ductwork SF, insulation, and control sequences from the bid package.
