Quantspan
Estimating and quantity take-off workspace
Turns drawing sets and specs into structured quantity take-offs, applies governed rate books, and blocks bid export until humans confirm AI-proposed lines.
Last verified 15 Sept 2026 · Updated 23 Sept 2026 · Metadata v5
Problem
Estimating desks still measure in Bluebeam and price in Excel, with no structural gate stopping underquoted AI-assisted bids from leaving the building.
Outcome
Defendable estimate packages with confirmed quantities, pinned rate books, named contingency and an immutable audit trail to bid export.

About this foundation
Quantspan is the pre-award pricing commitment layer for mid-market GCs and trade estimating desks. AI proposes quantities and draft pricing against versioned rate books; named humans must accept, adjust or reject before a bid package can export. Audit trails survive bid-protest and claims scrutiny. Planvector feeds sheet geometry; Contextkeep supplies past-job rates; Awardbind and Baselinecast receive released packages — Quantspan does not own field execution or contracts.
