The situation
Where they started.
Estimating is pre-construction's biggest bottleneck. The group quotes hundreds of bids a month with a ten-person estimating team, a single hyperscale data-center estimate can take one estimator two months, and what is visually on the printed page is what the subcontractor is on the hook for. The delta that hurts is schedules versus floor plans: a schedule says 420, the plans show 450, and the sub owns the difference. Every bid arrives as marked-up drawing sets and manual volumes with inconsistent or missing metadata, and nothing more is coming from the customer.
What FlatClaw does
What was built.
- Agents read the drawings' own embedded data natively, page by page, and build a census in which a unit is its family, zone and number: a tag drawn on ten sheets is one unit, a range tag is twenty, and duplicate sightings across the clean and marked-up sets collapse to one.
- On this bid: 1,045 units across 36 equipment families, every count citing the sheets it was read from, cross-checked against the drawings' own schedule tables as a second, independent confirmation.
- The counts reconciled with the estimators' proposal on the lines that drive price: 88 air-cooled chillers, 216 computer-room air handlers across four GPU halls and the in-building hall, 36 secondary chilled-water pumps. Where drawings and proposal disagreed, 161 fan-wall units on the sheets against 280 in the proposal, the spread was surfaced for adjudication instead of averaged away.
- The rough-order-of-magnitude estimate renders in the team's own schedule-of-pricing format, with the same line items, alternates and totals their proposals already use.
- Estimators steer it in plain language: increase all labor by five percent, union state, twenty percent spares. Role-based guardrails cap how far an estimator can move labor or spares without an estimation manager, and finalizing an estimate waits for human approval.
- Specifications and manuals answer questions in the same conversation: what a division requires, which risks the estimator highlighted, what the RFI clarifications say.
Results
What changed.
- A first-draft takeoff in hours against a manual count measured in weeks.
- Counts that reconcile with the team's own numbers, with sheet references anyone can open to check.
- Risk surfaced automatically: the 161-versus-280 spread is exactly the miss a subcontractor otherwise eats.
- Estimators spend their time on judgment, pricing and finesse instead of tallying.
- The same pipeline applies to the next bid set without re-engineering, and every correction trains the next run.
