Catch the drawing error before it becomes rework.
Draftrove reads engineering drawings, compares revisions, and flags where plans, schedules and sections disagree — then turns the findings into a structured review report your checkers sign off.
Drag across the sheet to compare Rev C and Rev D · fictional sample drawing
Most rework starts as a small inconsistency on paper.
Revision issued
Bar spacing on a slab plan changes from 200 to 150 mm. The revision cloud is missed.
Schedule not updated
The bar bending schedule still says 200 mm. Nobody cross-checks it before issue.
Built from the wrong value
Steel is cut and fixed to the schedule on site.
Rework and delay
The error is found at inspection: strip-out, re-order, programme slip, cost dispute.
A single project carries hundreds of drawings across structural, civil, drainage, architectural and MEP disciplines, each revised many times. Checking is done by eye: overlaying PDFs, reading revision tables, and remembering which schedule depends on which plan.
That works on small jobs and fails on large ones. Checkers run out of time before issue, contractors build from superseded or conflicting information, and each missed inconsistency becomes a site query, a variation or physical rework.
Six capabilities around one drawing set.
Revision comparison
Upload two revisions of a sheet and get every added, removed and moved element clouded, with a change list a checker can work through.
Revision changes stop hiding in undocumented edits.
From upload to issued review report.
Draftrove supports engineering checking; it does not replace it. Design responsibility and approval stay with qualified engineers.
STEP 1
Upload the drawing set
Drop in PDF drawings, scanned sheets, schedules and specifications, or a new revision of an existing set.
STEP 2
Extract and index
Title blocks, revision tables, notes, dimensions and schedules are read and linked to the project register.
STEP 3
Compare and cross-check
AI compares revisions and checks values and references across disciplines and documents.
STEP 4
Checker review
A named checker confirms or rejects each finding with the drawing extract beside it.
STEP 5
Issue the report
Approved findings become a structured engineering review report for the design team.

Search the drawing register, filter by discipline, open a sheet to see detected inconsistencies and the AI summary, approve or return it, then preview the review report. Runs on fictional sample data in your browser.

For the teams who issue, check and build from drawings.
Civil and structural design firms
Internal checking before issue is manual and squeezed by deadlines.
With Draftrove · Run revision comparison and cross-checks before every issue and send cleaner sets out.
Construction contractors
Building from a superseded revision or a conflicting schedule causes rework and claims.
With Draftrove · See exactly what changed in each new revision and flag conflicts before work is set out.
Infrastructure consultants
Large road, drainage and bridge packages with hundreds of sheets across disciplines.
With Draftrove · Keep one register per package and catch level, size and reference mismatches across the set.
Project and document controllers
Tracking revisions, transmittals and review comments across spreadsheets and email.
With Draftrove · Use one register and one report format for every review cycle.
How We Use Amazon Web Services
Draftrove's MVP architecture is designed on AWS around the life of a drawing: it is uploaded, its text and tables are extracted, it is compared against earlier revisions and related documents, and the findings are stored as reviewable project records. The serverless design keeps cost proportional to the number of sheets processed.
- Amazon S3: Stores uploaded drawings, revisions, schedules and generated review reports, organised by project.
- Amazon Textract: Extracts text, tables, title-block fields, revision tables and schedules from PDF and scanned drawings.
- AWS Lambda: Runs the processing steps: starting extraction, normalising values, comparing revisions and assembling reports.
- Amazon Bedrock: Interprets extracted drawing data to describe revision changes, reason about cross-document inconsistencies and draft review comments.
- Amazon DynamoDB: Holds project records: sheets, revisions, findings, checker decisions and review history.
- Amazon API Gateway: Provides the secure API between the Draftrove web application and the processing services.
