Code-edition consistency, occupancy, egress, and the referenced standards an IBC set should cite, surfaced for your judgment.

The International Building Code is the umbrella most other standards hang from. PlanFlag checks that an IBC set is internally consistent and cites what it should, then hands the findings to a licensed reviewer.

What PlanFlag checks against the IBC

RFI
The cover sheet cites one IBC edition while the structural notes reference criteria from a different edition: a code-edition conflict to resolve.
Illustrative example: always verify against your own set.

One review, one price

Every review is the full review: each sheet read, then the set checked against itself, with comments ranked and kept to about the size of a reviewer's own markup. $1 a sheet, $50 minimum. A hold is placed on your card before the review runs and charged when it finishes; if the review fails, the hold is released.

Where the engineer stays in control

PlanFlag surfaces candidate findings for a licensed professional to evaluate. It does not perform engineering, and it does not seal, stamp, or approve anything. The engineer of record remains solely responsible for the design, and the reviewing professional remains responsible for every decision to act, or not act, on a finding. A clean or short report is not evidence that a set is complete or compliant; it describes only what was assessed.

The goal is the disciplined review a good reviewer already does: "here is what should be on this sheet, let me find it, and let me investigate the unexpected," run consistently and fast, with receipts.
