The Codes That Govern Every Duct Takeoff
Duct systems that ignore U.S. code requirements risk failed inspections, stalled projects, and dangerous fire or air-quality hazards. Following IMC, NFPA, SMACNA, and ASHRAE standards protects occupant safety, ensures energy efficiency, and keeps your project moving without rework or violations.
Our estimators track code updates through ICC, SMACNA, and ASHRAE year-round, attend industry training sessions, and cross-check every takeoff against the latest adopted state and local amendments before the final bid. During quantity extraction, our team at Design and Bids flags pressure class and duct type per IMC/SMACNA specs. At the material listing stage, we verify insulation R-values against IECC and fire-rated components against NFPA 90A/90B. Before final pricing, we cross-check leakage limits and sealing requirements against ASHRAE 90.1, ensuring every line item is code-ready before submission. |
International Mechanical Code (IMC)
The IMC governs commercial and multi-family ductwork, defining pressure classifications and supporting SMACNA standards for sheet metal gauges, reinforcement, and joint integrity, ensuring consistent installation practices nationwide for contractors and inspectors.
SMACNA Duct Construction Standards
SMACNA's HVAC Air Duct Leakage Test Manual establishes leakage classifications, including Leakage Class 3, 6, 12, 24, and 48, each corresponding to allowable leakage rates per 100 square feet of duct surface area, giving inspectors a measurable benchmark on nearly every project.
ASHRAE Standard 90.1
ASHRAE Standard 90.1 governs commercial building energy performance and includes duct leakage limits that typically do not exceed 4% of design airflow for new commercial systems. It becomes enforceable once local jurisdictions adopt it into their building code.
International Residential Code (IRC)
Residential duct systems in one- and two-family homes fall under the IRC and NFPA 90B, setting minimum requirements for duct sizing, insulation, sealing, and combustion air to ensure safe, efficient residential HVAC installations.
NFPA 90A & 90B
All duct materials must meet a flame spread index of 25 or less and a smoke-developed index of 50 or less under NFPA 90A and 90B, with every joint sealed using welds, gaskets, mastics, or UL 181-listed tapes to prevent fire spread through ductwork.
International Energy Conservation Code (IECC)
The 2021 IECC caps total duct leakage at 4 CFM25 per 100 square feet of conditioned floor area, setting residential and commercial efficiency baselines that directly shape how we size and specify duct runs.
What You Receive: Our Duct Takeoff Deliverables
Every duct takeoff report follows U.S. industry standards, giving you accurate, actionable data ready for bidding, ordering, and installation.
Material Quantity Takeoff
Our ductwork takeoff estimating firm provides a complete count of duct sizes, fittings, dampers, and insulation, measured directly from plans per SMACNA and ACCA Manual D standards.
Unit Pricing Breakdown
We apply current market rates per item, including material and labor costs, so your bid accurately reflects real, up-to-date pricing.
Duct Sizing & Specifications
Our experienced estimators provide CFM-based sizing, gauge thickness, and pressure classification for every duct, as specified by IMC and SMACNA construction standards.
Fitting & Accessory Schedule
We provide a detailed, itemized list of elbows, transitions, dampers, diffusers, and hangers, so nothing is missed during ordering or installation.
Code Compliance Notes
Our takeoff report includes information on leakage limits, insulation R-values, and fire-rating requirements, flagged per IECC, NFPA 90A/90B, and ASHRAE 90.1, for inspection readiness.
Scaled Takeoff Markup Drawing
At Design and Bids, we also provide marked-up digital drawings showing duct runs, quantities, and locations, giving your team a visual reference alongside the numeric takeoff data.
Residential Sector
For residential projects, we provide duct sizing, insulation R-values, and fitting schedules compliant with IRC and NFPA 90B, along with leakage estimates and material lists tailored to single-family and multi-family home construction.
Commercial Sector
For commercial buildings, we deliver pressure-classified duct takeoffs, ASHRAE 90.1 leakage compliance checks, fire-damper and penetration schedules under NFPA 90A, and full material quantities for offices, retail, and multi-story developments.
Industrial Sector
For industrial facilities, we provide high-volume ductwork takeoffs, exhaust and ventilation system quantities, SMACNA pressure classifications, and gauge-specific material lists suited to warehouses, plants, and large-scale mechanical installations.
