About
PreConstruct AI is a web-based construction takeoff and estimating application for subcontractors bidding interior finishes, concrete, and wood framing work from PDF drawing sets. It reads drawing scales and uses plan notes, schedules, and partition legends to help identify and measure walls, ceilings, and concrete quantities. AI-assisted wall suggestions are in beta and are reviewed, approved, or adjusted by the estimator. Approved quantities become material lists for items such as studs, board, insulation, tape, compound, paint, concrete, and rebar, with calculations and drawing-sheet references. Estimators can apply their own material prices, create proposal PDFs, and export data to Excel or CSV. Projects can use imperial units, metric units, or both. The application supports estimating workflows; estimators review measurements and quantities before submitting a bid.

About
Tagsight is the system of record for engineering data. It reads your drawing set into the instrument index, I/O list, equipment list, line list, and valve list a project runs on.
It reads P&IDs, single-line diagrams, loop diagrams, datasheets, and cable and junction-box schedules. Scanned sheets and CAD-exported PDFs read the same way. Every tag is classified to the standard the drawing already uses, whether that is ISA 5.1, KKS, IEC 81346, NORSOK, DIN 19227, or an operator-house convention.
An engineer confirms or corrects each read before anything leaves the tool. The register is reviewed, not assumed.
Tagsight exports to Excel, CSV, TIA Portal XML for Siemens S7, Rockwell L5X for Studio 5000, PLCCreator, DEXPI, JSON, and annotated PDF. It compares revisions so a Management of Change review shows only what changed. A REST API and an MCP server connect it to the rest of the toolchain.
