Reads the full drawing and specification set and reports conflicts, omissions and coordination items, each cited to the sheet.

AI-powered construction plan analysis
PBG Precon reads an entire drawing set the way an experienced preconstruction manager does — finding conflicts, measuring the work, defining the scope, pricing it and leveling the bids. Every conclusion is cited to the exact sheet and note it came from.
Six modules, one set
Upload the documents once. Each module works from the same indexed set, so review findings sharpen the scope, the scope sharpens the bid leveling, and nothing gets retyped.
Takeoff
Automatic scale detection plus on-drawing measurement of lengths, areas and counts, with visual verification of every quantity.
Learn about Takeoff →Scope
Bid-ready trade scope sheets — inclusions, exclusions, clarifications and allowances — written from your documents.
Learn about Scope →Estimating
Turns measured quantities and defined scope into structured line items with the assumption behind each one stated.
Learn about Estimating →Bid Leveling
Normalizes subcontractor proposals from PDF, Excel or CSV and exposes coverage gaps, exclusions and price spread.
Learn about Bid Leveling →Intelligence
Ask anything across the project and get an answer quoted from the sheet it came from, with a citation that jumps to the drawing.
Learn about Intelligence →What a finding actually looks like
A representative product demonstration of Plan Review and the envelope checklist. Every real finding carries the sheet number and the verbatim printed text it came from, so you can open the drawing and check it yourself.
Why preconstruction, and why now
Cost is decided early
Many costly overruns begin with drawing conflicts, scope gaps and unresolved assumptions that were never caught before bidding — a schedule that disagrees with a plan, a detail called out and never drawn, an allowance carried without a basis.
The knowledge does not scale
The people who catch those problems do it from experience. That review cannot be run on every set, on every bid date, by everyone on the team.
Evidence, not output
Findings, answers and scope items carry the sheet number and the verbatim text they came from, verified against the source — so they can be checked, not just believed.
