Structural plan review, run consistently
Member schedules, connections, load paths, and delegated-design completeness, surfaced for your review against AISC 360 and ACI 318.

What PlanFlag checks on a structural set
- Member schedules vs. plans: beam, column, and footing schedules cross-checked against framing-plan callouts at each gridline.
- Connection detailing: presence and consistency of connection details, referenced against AISC 360 / ACI 318.
- Delegated design, at the set level: delegated connection design is standard practice; PlanFlag checks that the set provides the design criteria and loads the delegated engineer needs somewhere in the documents, rather than flagging an individual detail for not repeating them.
- Load-path & lateral-system continuity: continuity of the gravity and lateral systems across plans and elevations.
- Schedule arithmetic: numeric consistency within schedules and against general notes.
A framing plan calls a W21×50 at a gridline while the beam schedule lists a W21×44 for the same mark: a schedule/plan mismatch to resolve.
Illustrative example: always verify against your own set.
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.
