Chicago HVAC Estimating FAQs
How does the Chicago Electrical Code (Title 14E) impact electrical takeoffs?
Title 14E prohibits NM cable (Romex) and severely restricts MC cable. All branch wiring must run in EMT or rigid steel conduit with steel boxes, which we calculate with precision bending, coupling, and hanger counts.
How do you account for Chicago union trade wage agreements and productivity?
We calibrate labor using current IBEW Local 134, Pipefitters Local 597, and Sheet Metal Local 73 collective bargaining agreements, with logistical factors for high-rise material hoisting and winter heating.
