// For estimators
You're carrying four open tenders, three close this week, and the youngest takeoff just missed a whole section of curtain wall. Marapone builds private AI that does live takeoffs from your drawings, levels sub quotes apples-to-apples, and reads the spec for the clauses that bury margin. You own the model. You own the data. No subscription.
Built for in-house estimating teams and independent estimators on ICI and high-end residential · Toronto + Rome
// The four things that eat your tender week
PAIN 01
Three days clicking through PDFs to count fixtures, measure runs, tally door schedules. By the time you have quantities, you've spent the budget for actually thinking about the bid.
→ FIX: Live Takeoff & Cost Intelligence reads the drawings, runs the takeoff, and pulls live unit costs from your historical jobs and supplier data.
PAIN 02
Mech sub A excludes controls, mech sub B includes them but assumes a different sequence, mech sub C didn't read the addendum. You spend an afternoon trying to make them apples-to-apples and you still miss something.
→ FIX: Subcontractor Scope Gap Finder normalizes every quote against the spec, marks every inclusion and exclusion, and shows you the real comparison.
PAIN 03
An onerous warranty clause, a custom liquidated damages provision, an unusual schedule sequence — buried where nobody read. You won the job. Then you found it. Then the contingency was gone before mobilization.
→ FIX: Tender Package Risk Scanner reads the entire spec and flags every clause that deviates from your standard baseline, ranked by exposure.
PAIN 04
Addendum 4 changes three sections, deletes one, adds a new spec for the lobby. You have to re-do the takeoff, re-issue to subs, re-level. You barely make submission with a number you don't fully trust.
→ FIX: The build re-runs the affected takeoff regions and re-levels the impacted scopes automatically, so addenda are minutes not hours.
// What we build for estimators
Most estimating builds bundle these three modules. Trained on your historical jobs, your unit cost library, and your trade quote templates. Not a generic chatbot.
BUILD 01
Reads the drawings, generates the takeoff, and ties each line to a live unit cost from your historical jobs and supplier sheets. The estimator's three-day click-counting becomes a half-day review of a structured first pass.
BUILD 02
Normalizes every sub quote against the spec, surfaces inclusions, exclusions, and conflicting assumptions, and gives you a true levelling sheet. No more pricing the same scope twice or missing it entirely.
BUILD 03
Reads the full spec — every page — and surfaces non-standard clauses ranked by dollar exposure. You walk into the bid review knowing exactly where the contingency needs to sit.
// What estimators say after the build
"Our chief estimator used to do hand takeoffs for three days. Now she reviews a structured first pass in half a day and spends the saved time actually thinking about strategy. We've cut bid-to-submit time roughly in half on commercial work."
// Free, real, no obligation
Pick one tender — open or recently closed. We'll run the drawings and the spec through the same system we'd build for you and send back a takeoff sample plus a written risk report, usually within 24 hours.
