Struction is an AI-powered construction estimating platform that traces every answer, count, and scope item back to the source contract documents—drawings, specs, and model elements—so estimators can verify results instead of trusting black-box outputs. It combines project-wide chat, markup-style tracing, manual and automated takeoff, and generated bid forms into one workflow. The platform also opens the federated BIM model to every estimator, not just VDC specialists, making risk and clash detection accessible across the team.

Problem
Construction estimators often rely on AI tools that produce takeoffs, scopes, and risk assessments without showing their work, forcing users to trust black-box outputs. This lack of traceability slows bid preparation, increases the chance of missed scope or hidden risk, and limits access to BIM and VDC insights to specialized roles only.
Solution
Struction provides an AI-native estimating platform where every output—answers, counts, scope items, and risk flags—traces back to the specific sheet, spec section, or model element it came from. Users can ask questions in plain language across the entire document set, trace markups and callouts into linked chains, and generate takeoffs manually, with AI assistance, or automatically from schedules. The platform also writes exportable bid forms per discipline directly from the drawings and specs, with every inclusion sourced. A federated BIM model opens to all estimators, not just VDC seats, so risk, clash, and scope-gap detection is accessible to the whole team.
Target Audience
Primary users are construction estimators, preconstruction teams, and bid managers at general and specialty contractors who need verifiable AI assistance for takeoffs, scope definition, and risk analysis during bid preparation.
Features
- Project-wide AI chat that answers questions in plain language and cites the exact sheet or spec section for every response
- Markup-style tracing with pens, clouds, and notes, plus linked callouts, details, and spec references that walk from plan to detail to spec to scope
- Three takeoff modes—manual snip-and-count, AI-assisted, and fully automated schedule extraction—with every count tied to a scope item and source sheet
- Auto-generated, exportable bid forms per discipline, with each inclusion showing where it was found in the documents
- Federated BIM model with risk, clash, and scope-gap detection surfaced with severity and source, usable by any estimator, even via game controller
