Audit Construction Drawings and Spec Sheets Against Your Bill of Quantities

Upload drawing sets, schedules and spec sheets and get door, window and beam schedules, revision blocks and material notes as data — then compare them with your bill of quantities to find mismatches before they reach site.

Schedules read as tables

Door, window, beam and rebar schedules come out row by row, not as a picture.

Revisions never slip

Revision letters, dates and notes are tracked across the whole set.

Mismatches found for you

Quantities on drawings are compared with your BOQ, submittals and change orders.

Drawing audit questions

Does it read CAD files?: Export to PDF first; scanned and vector PDFs both work.
Can I check submittals and change orders?: Yes. Add them to the same folder and they are compared too.
How large a set can I upload?: Hundreds of sheets; large folders run on credits with a firm quote first.
