The AI operating system for contractor estimating and procurement.
GRADIX reads your plans, specifications, and bid documents, then helps your team take off quantities, generate supplier RFQs, compare quotes, and assemble a defensible bid — with every number traceable back to its source.
Access is limited while we work closely with early contractors.
Built for heavy civil, excavation, and utility work.
Not a generic takeoff tool — GRADIX is purpose-built around how contractor estimating and procurement actually works, from document intake through bid submission.
Project understanding
Upload plans, specifications, contracts, and addenda — GRADIX reads the full package and builds a working understanding of the project.
Takeoff
Quantities are extracted from plan sheets and run through deterministic, unit-tested calculations — never a black-box AI guess.
Supplier RFQs & quote comparison
Generate RFQs from your scope, then normalize and compare incoming supplier quotes side by side.
Bid assembly & risk review
Assemble a bid estimate with every line traceable back to its source document, and surface risks before you submit.
