Industries/HVAC & Mechanical
Operon reads your mechanical plans, schedules and specs, takes off the whole set, checks submittals against the spec and sorts the bid inbox, so your estimators and project engineers spend their time on pricing and the job.
The unit, part by part
Operon reads a mechanical set the way your estimator does: the rooftop unit and everything in it, the curb it sits on, and the gas, condensate and power runs that serve it, each counted and traced back to the sheet. Hover any part.
The work today
01
Bid volume capped by headcount
Every bid needs a full take-off, and a good mechanical estimator is the scarcest person in the building. The work you can chase is limited by how many sets your team can count.
02
Counts that drift from the drawings
Scales, revisions and addenda move under you. A VAV box missed on one sheet, or a schedule that disagrees with the plan, becomes margin you give back on the job.
03
Scope between the trades
Controls, insulation, fire dampers and equipment furnished by others sit at the edges of Division 23. Gaps found after award are gaps you pay for.
04
Knowledge that walks out the door
How your company prices a job lives in a few senior estimators and in years of old bids that nobody can search.
What Operon does
Every set counted, not sampled.
Equipment, duct by size and gauge, fittings, terminal units, diffusers, dampers and piping, counted across every sheet and linked to the region of the drawing each quantity came from.
Click any quantity to see the sheet, the region and the symbol it was counted from.
Quantities measured from a printed scale are flagged as provisional until someone checks them.
Exports shaped to the spreadsheets and estimating tools your team already prices in.
Catch the conflicts before bid day.
Equipment schedules are reconciled against what is drawn, and the plans against Spec Division 23, so mismatches and missing scope surface while there is still time to ask.
Units on the schedule that aren't drawn, and drawn units that aren't scheduled.
What each addendum changed, sheet by sheet, before you reprice.
Furnished-by-others and not-in-contract items separated from your count.

Check what was submitted against what was specified.
Operon compares product data against the spec section and schedule, flags deviations and missing data, and drafts review comments for your project engineer to approve.
Capacities, ratings, materials and accessories checked against the section that governs them.
Sound data, certifications and performance curves that should be there and aren't.
Draft comments go to a person; nothing is returned without their sign-off.

Start the next estimate from what you already know.
Old bid sets, take-offs, scope letters and change orders become one knowledge base, so a question about how you carried controls on the last lab job takes seconds, not a call to someone's old laptop.
Every answer cites the bid, the sheet or the scope letter it came from.
Search across years of jobs by system, spec section or building type.
Access follows your divisions, offices and roles.

All three carried controls as a subcontract quote. Two excluded BAS integration, and one carried an allowance for graphics.

From the journal
No. Operon produces the quantities and the evidence behind them; your estimators price them in the tools they already use. Exports are shaped to fit your templates.
Scale is read from each sheet and checked against known dimensions. Anything measured from a printed scale is marked provisional until a person confirms it.
Yes. Past bid sets, take-offs and change orders become a searchable knowledge base, so the next estimate starts from what your company already learned.
Scope notes and responsibility matrices are read alongside the plans, and items marked by others or not in contract are kept out of your count.
