THE ESTIMATOR AGENT · FOR RESIDENTIAL BUILDERS
The Estimator Agent. A day off every quote.
Reads your drawings, voice notes, and project context. Produces a reviewable scope with assumptions, exclusions, evidence links, and the open questions a junior estimator would miss. Your team approves before anything ships.

EVIDENCE
Your team approves before anything ships.
Every scope item points at its source. Every line links back to the drawing region, the voice note, or the invoice that produced it.
Every scope item is reviewable. Open questions, confidence levels, and assumptions are visible on every artefact — your estimator approves before anything ships.
Every decision leaves a trail. Edits, approvals, rejections, and reruns are timestamped and traceable.

A day off every quote. An audit trail for every decision.
Before
With BuildGuider
Three hours copying drawings into a spreadsheet.
An hour reviewing a generated scope with evidence links.
Scope items missed because the WhatsApp comment never made it to the quote.
Voice notes captured against a viewport and pulled into the scope automatically.
Junior estimator misses an exclusion. Found out in week six.
Exclusions surfaced on every line item, with confidence chips.
Different estimator, different format every time.
One consistent reviewable scope structure across every job.
None of this replaces your estimator. It takes the boring half of the job off their plate.
A WORKED EXAMPLE
From a Rev B drawing pack to a reviewable scope, in 90 minutes.
Step 1 — Upload.
Drawing pack PDF, two voice notes recorded against viewports 1 and 3, one previous-project invoice. Five minutes.
Step 2 — Read.
The Estimator Agent identifies rooms, viewports, components, the existing-vs-proposed split, and parses voice notes against the right context. Twenty minutes.
Step 3 — Generate.
A scope of 38 items with evidence links, 4 open questions, 7 assumptions, and 3 exclusions. Twenty minutes.
Step 4 — Review.
Your estimator opens the scope, edits 6 lines, rejects 2, adds 4. Forty-five minutes. Total: 90 minutes from drawing pack to a quote-ready scope.
