How Automated Missing Drawing Detectors Save Estimating Hours

Detecting unattached drawing sheets cited in specification sections before trade pricing cutoffs.

Contract specifications frequently reference architectural, structural, or MEP drawing packages that were omitted from the owner's primary tender download bundle.

The Cost of Missing Drawings When trade subcontractors price jobs without complete drawing packages, addenda requests spike in the final 48 hours before closing. Identifying missing drawing series (e.g. A-100 series architectural sheets cited in Section 01 10 00) on Day 1 gives contractors ample time to submit RFIs to the purchasing authority.

BidReady's automated gap audit cross-references specification citations against uploaded PDFs to flag unattached drawings instantly.
