CHANTILLY, Va. — In an effort to help contractors prepare more accurate and competitive bids, the Sheet Metal and Air Conditioning Contractors’ National Association’s (SMACNA’s) HVAC Contractors Council Steering Committee has released the newly revised HVAC Bid Specification Reference Manual.

Changes include new information in Division 23 — heating, ventilating, and air conditioning — as well as revised diagrams and updated references to SMACNA technical manuals and standards.

This manual was first published in 2007 as a guide to assist HVAC contractors in preparing bids, designers in preparing construction documents, and owners in preparing bid and contract documents. Originally based on the HVAC specific sections of the 2004 CSI MasterFormat, the new document has been updated to match the 2016 CSI MasterFormat.

The manual is available free to members on SMACNA’s Project Management webpage at, and for sale to others for $185 in SMACNA’s online store at
