One subcontractor's desk, January to September 2026.

Read from the bid log and the award list, deduplicated by project. The client is a commercial specialty subcontractor in the Carolinas; its name stays with it.

Where the invitations came from

Invitations read and bid in 2026 for the desk's clients. Wherever the GC's portal is, the agent fetches the documents and the desk runs the bid the same way.

$9,630 change order, kept whole

Extra work on a healthcare job. The desk had papered it the day it happened: what, where, who, quantities, thirty-nine photographs. A draft had conceded down to $6,230; the signed order came back at $9,630.

$23,000 of unpriced work caught before signature

A restaurant subcontract arrived with scope the proposal never carried. One line on the review, "do not sign as written", and the contract came back corrected.

04 · How it works

Forward the invite. Sign the number. Send.

Forward the GC's invitation to cs@mindatu.com

The email itself, portal link and all. BuildingConnected, Procore, iSqFt, SmartBidNet, PlanHub or a direct email. That is the whole step.

The agent reads, measures, prices and drafts

Every sheet, every addendum. Every quantity graded and linked to the sheet it came from. Estimate in your workbook, proposal on your letterhead, draft only.

Your estimator signs; you send

Where the drawings do not prove a number, the line says FLAGGED. Nothing leaves without a human signature, and nothing is sent to a GC by us.

"The agent measures. I judge. Where the drawings don't prove a number, the line says FLAGGED, and I would rather show you seven flags than one guess."

08 · Questions

Six answers.

Which trades?

Any scope a GC can put on an ITB, divisions 03 through 33. The published sample is a four-trade interior renovation. A trade-specific measurement rule ships only where a real one exists; where it does not, the line is flagged rather than estimated.

Which portals?

BuildingConnected, Procore, iSqFt, SmartBidNet, PlanHub and direct email invitations. Forward the invite; the agent fetches the documents from wherever they live.

How accurate is it?

We do not quote a percentage. Every line carries a GOLD, SILVER or FLAGGED grade with the sheet it came from. The public sample is 37 lines: 27 GOLD, 3 SILVER, 7 FLAGGED, and the seven are published with the sheet each failed on.

Who signs, and who sends?

Nursultan Temirbaev, estimator of record. Nothing leaves without his signature, and nothing is sent to a GC by us. You send.

Where do my documents go?

They stay in our shop. Never resold, never used on another sub's bid. We never work for two competing subs on the same bid.

How do I stop?

Per-bid work ends when the bid ends. The department is month to month; stop by email. No card on the free takeoff, no login, no software to remove.
