Reads any residential plan set
Vector or scanned PDF, schedules and specs, measured to scale.
Read twice. Both must agree. A GC that runs the job.
Every quantity read straight off your plans. The make-or-break numbers checked twice.
GC770 reads your plans, then reads them again independently. On every make-or-break item the two readings must agree or the estimate blocks. Then a GC brain runs the whole job across every trade, from the itemized takeoff to the schedule to the owner's buy-list.
GC770 runs as a concierge during the pilot. You send the plan set, we run it, and the full package comes back to you. Self-serve upload is next.
Two-vendor must-agree checkEvery plan is read a second time, independently. On the make-or-break items both readings must agree, or it blocks.A GC that runs the jobNot just a price. The schedule, a dated buy-list, and a client timeline under your name.
Built by a licensed California general contractor.
Read twice, must agree
Every plan is read twice, independently. Both must agree, or it blocks.
One reader can misread a plan and stay confident about it. So every plan is read twice, and the second reading is produced independently of the first. On every make-or-break item the two have to agree. If they disagree, or only one reading is available, the estimate does not finalize. It blocks.
Two independent lanes
Every plan is read blind by two separate lanes. Neither sees the other, so a miss in one does not carry into the other.
Genuinely independent
The second reading is produced independently of the first, so the two do not share a blind spot. A repeat of the same reading would not count.
Line-by-line reconcile
When the full two-lane pass is run, the two complete takeoffs reconcile line by line, not just a spot check.
Auditable GC ruling
When the two lanes disagree, a recorded GC ruling resolves it. Fail-closed, never a silent override, and every ruling is logged.
Every quantity traces to a sheet
Nothing is eyeballed. Each quantity points back to the sheet it was read from.
Reads image-only sheets by vision
Scanned or image-only sheets are read by vision, not skipped for lack of machine text.
Why it matters
Read six drilled caissons as ordinary spread footings and the whole foundation number is wrong. That kind of catastrophic misread does not pass unchecked: both lanes have to agree on the foundation type, or the estimate is blocked, not quietly shipped.
And every gate has to be clean.
- The full plan set is proven read, sheet by sheet
- Image-only sheets are truly vision-read, not skipped
- Every material is read from the plans, never defaulted
- Steel is taken off piece by piece
- Code is checked current, not stale
- Every quantity is measured, not guessed
The estimate finalizes only when the two lanes agree and every gate is clean. These checks cannot be turned off. The two-vendor check runs automatically, so there is no manual re-check step on our side. You still confirm the numbers with your own licensed professional before you rely on them.
How it works
From plan set to a breakdown you price.
GC770 measures everything and builds the breakdown. You fill in your own unit prices, by the square foot or by line item, so the totals are always yours. We do not set prices.

One trade or the whole job
Need just the electrical? Just the framing?
You do not have to price the whole job to get value. Ask for one trade and get that trade's material takeoff, read off the sheets that trade owns. The full job comes as a tab per trade in one workbook.
Electrical
Devices, fixtures, home runs, panel and load calc, by circuit.
Framing
Lumber by size, board feet, plus the Simpson connector schedule.
Concrete and rebar
Yardage by pour, rebar by bar size with laps and dowels.
Drywall
Board by type and thickness, sheet count, tape, mud, and texture.
HVAC
Tonnage, equipment, duct runs, and register count by room.
Roofing
Squares by slope, underlayment, flashing, and edge metal.
Every quantity is tagged for where it came from: read off the plans, measured to scale, or flagged as an allowance to confirm.
Systems by calculation
No MEP sheet? Get a starting layout and load calc.
When your set has no mechanical, electrical, or plumbing sheet, each system is sized by code calculation under Title 24 and laid out room by room against your floor plan, so your licensed professional has real numbers and a layout to finalize, stamp where required, and permit. It gives you a head start; it does not replace your licensed designer or engineer.
HVAC
Load calc to tonnage, equipment, duct runs, and registers by room.
ACCA Manual J / S / D, Title 24 Part 6
Electrical
Service and load calc, branch circuits, and a panel schedule.

TIA-570
Solar and battery
Array sizing, panel and battery layout, and tie-in.
Title 24 Part 6
Where the line is
This is a starting layout and calculation to hand to your licensed professional, not a finished engineering design and not a stamped document. Your engineer or licensed designer of record sizes, finalizes, and signs off for permit. The tool reads and cites the code; it does not stamp or certify that anything meets it.
The GC runs the job
It does not just price the job. It runs it.
Most tools stop at a number. GC770 keeps going: it turns the schedule into a procurement plan, a dated buy-list, and a client timeline under your own name, so nothing slips through the cracks between the estimate and the first day of work.
A dated buy-list from the schedule
From the construction schedule, GC770 issues a dated owner buy-list. Windows, doors, cabinets, and appliances are flagged to order first, because they take months. In-wall valves are reminded weeks before rough plumbing, and fixtures, trim, and lighting before trim-out, so the wall never waits on a part.
A client timeline
A Gantt chart of the whole job, trade by trade, with the critical path called out. It carries your company name and logo, not ours.
Inspection notices at every stage
The inspections the job needs at each stage, AHJ plus any special or deputy inspection, called out in sequence.
Schedule and critical path on every estimate
Every estimate ships with the build schedule and the critical path, not just a number.
A GC brain over the whole job
A general-contractor brain coordinates every trade skill across the estimate and flags what needs your attention before it reaches you. One brain over the whole job, from the dirt to the finishes.
What you download
One read, a full set of documents.
From a single reading of your plans, you get the paperwork a real estimate needs, ready to share with your client, your subs, and your supply houses.
Takeoff PDF and Excel
The full itemized takeoff, with a tab per trade in the workbook.
Open-questions list
The confirm list leads the deliverable, so nothing is assumed silently.
Per-room finish schedule
Finishes itemized room by room, matched to the plans.
Schedule and critical path
Build order, trade durations, and the critical path for the job.
Required-inspections notice
The inspections the job needs, in sequence.
Bill of materials and supplier requests
A BOM plus draft quote-request emails, one per supply house.
Signable proposal
A client-facing proposal at your own lump-sum price, ready to review and sign.
Accuracy class on every estimate
An honest accuracy band on the number, so you know how firm it is.
The priced proposal is a document you review, not a binding bid and not the construction contract itself, until you put it into a signed agreement. Every estimate carries its accuracy band and the reliance note below.
Remodels and photos
Remodeling? Scope it from photos.
No plan set for the remodel? Send photos of the space and GC770 reads the scope, so you can price the work. For anything that needs measuring, include one known dimension in the shot, a door width, a tape measure, or a tile, so it can set the scale. Without a scale reference, nothing off a photo is presented as a measurement.
Reads the space
Point it at photos of the room and it scopes the trade and the condition to price.
One measurement sets the scale
Put a known dimension in the shot, a door, a tape measure, or a tile, and quantities off that photo are measured to scale. Without one, nothing from a photo is ever presented as a measurement.
Flags code and quality
Calls out visible code or quality concerns, tied to the section where one applies.
This is an advisory read to help you scope and look in the right place. It is not a stamped inspection and does not replace a site visit by a licensed professional.
It asks instead of guessing
The clarification loop is the accuracy feature.
After reading the plans, GC770 flags anything unclear and asks you a few targeted questions before it finalizes the takeoff. When something cannot be read from the plans, it gets flagged, not guessed.
- Reads the whole set first.
- Flags what is unclear.
- Asks you, then finishes.
Building code
Ask a code question, get a straight answer.
GC770 has a California building-code brain built in. Ask in plain English while you estimate, and it answers and points you to the code section it comes from, so you are not digging through the code book mid-bid.
Answers cite the applicable California code section. Confirm with your local building department before you build.
Ask the trade
Ask the electrician. Ask the plumber.
Every trade knows its own code, so you can ask a trade a trade question and get a straight answer with the section cited: the electrician on the electrical code, the plumber on gas sizing, the framer on connectors. Ask about the whole project, or one trade at a time.
Answers are informational and cite their code section. They are not legal advice or a substitute for your authority having jurisdiction.
Ask your GC
A general contractor on every job.
Read the deliverable once, then just ask. GC770 answers from your own takeoff, your rooms, and the code, and points you to where each answer comes from.
It answers only from measured, tagged numbers. Ask for something finer than the plans show and it tells you, instead of guessing.
Ask your takeoff
Any room, any material, any line. It answers from what it measured, and shows the basis it came from.
Buy lists
Project totals with waste and order quantity, or a full material list for one trade to hand your supplier.
What is left to buy
Send your invoices and material receipts. GC770 matches them to your list, shows what you already have and what is still missing, and hands you a shopping list of what is left to buy, with your real cost tracked on the job.

Accuracy and trust
The software does the work. An expert checks it before you rely on it.
GC770 runs the takeoff and self-checks its own numbers. A person reviews the work before it reaches you. You stay in control of the final call.
Please read
Every estimate is generated by AI software to save you time and is informational, not a final bid, an inspection, or an appraisal. You are responsible for verifying quantities, pricing, and code against the plans and field conditions with a licensed professional of record before you rely on it. The software reads and cites the code; it does not act as your engineer and does not stamp or certify that a member meets code. It produces estimates only; it does not adjust, file, or negotiate insurance claims.
Your plans stay yours
Your drawings are never used to train any model. We read them to build your estimate, and that is all.
