Take off the plans. Price the duct. Send the proposal.
Ductora is estimating software built by an HVAC estimator. Trace duct on your PDF plans, price it by SMACNA gauge, pressure class and crew labor, and hand the GC a clean proposal, all from the same takeoff.
Everything between the plan set and the bid price
One program for the whole sheet metal estimate. No spreadsheet copying, no second takeoff tool.
Takeoff on the PDF plans
- Trace runs in linear feet and click counts for fittings, dampers, diffusers and equipment.
- Cover mode draws each duct at its real width, so a wrong size or scale shows up at a glance.
- Split screen, a second monitor, Ctrl+arrows to change sheets, and an audit trail of every line.
- Global edit changes wrap, gauge, pressure class or system on many lines at once.

Priced the way a sheet metal shop prices
- Weight from size, length and SMACNA gauge, by material: galvanized, stainless, black iron, aluminum.
- Pressure class and seal class change the gauge, joints and reinforcement, and sealing labor.
- Fittings, dampers and access doors per each; hangers generated with every run; insulation by type.
- Labor by crew: open shop by state, union, or prevailing wage. Rentals, subs, tax, overhead and profit.

Addenda and revised sheets, without starting over
- Load the revised set: each page replaces the sheet with the same number, and your takeoff stays.
- Red is what was removed, green is what was added. Every change is boxed and numbered.
- Ductora counts the takeoff marks that sit inside a change, so you know what to re-check.
- Overlay any two sheets, Bluebeam-style.

Breakouts and alternates the GC asks for
- Split the base bid by floor, area, phase, system or sheet. The groups add up to the bid to the cent.
- Price add and deduct alternates from the takeoff, with tax, overhead and profit included.
- Both print on the proposal.

A proposal and an Excel workbook the GC can read
- Scope, inclusions, exclusions, qualifications, payment terms and signature block, with your logo.
- Ductora warns you when an exclusion contradicts what you priced.
- Export the whole estimate to Excel with live formulas: change a rate and the totals follow.

Your bid board
- Next bid due, the next 14 days, and every project's status from draft to won or lost.
- Bids per month, win rate, and a board you can drag bids across.
