IBC plan review, run consistently

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

• Code-edition consistency: the IBC edition cited on the cover, notes, and details checked for agreement (and against the jurisdiction where known).
• Referenced standards present: the load, concrete, steel, and electrical standards an IBC set relies on (ASCE 7, ACI 318, AISC 360, NEC) are cited and consistent.
• Occupancy and use: occupancy classification stated and carried consistently across the set.
• Cross-sheet consistency: code criteria that appear on multiple sheets agree with each other.

Three tiers of depth

Essential runs a single best-in-class pass for a fast, affordable first read. Professional adds a reasoning pass that weighs findings against each other and drops false positives. Flagship layers cross-sheet reasoning, table/schedule analysis, and visual verification on top: the deepest coverage for high-stakes sets. The same findings get a deeper verdict as you move up; depth means coverage, not more noise.

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.
