Structural Review-and-Seal — Responsible Charge and Delegated Design
Structural stamping carries the strictest version of the rule that governs all of it: an engineer may seal only work prepared by them or under their responsible charge — or work they have reviewed so thoroughly that they can take professional responsibility for every sheet. Structural sets test that rule hardest, because so much of modern structure is delegated: trusses, precast, cold-formed steel, PEMB foundations, curtain wall, solar racking — components designed by specialty engineers that still have to land in one coherent, sealed structure. This sector is the honest map of that work: what a structural review checks, what delegated design requires, and where the line sits that no stamp may cross.
What the Scope Actually Includes
- Load-path review end to end: roof to foundation, gravity and lateral — the path traced on the submitted set, with the breaks named where it stops adding up
- Calculation verification for the primary structure: beams, columns, diaphragms, shear walls, and foundations re-checked against the project's real loads and code edition
- Delegated-design coordination: truss, precast, PEMB, and component submittals reviewed against the design criteria the engineer of record published — the connection where delegated work usually fails
- Existing-structure and retrofit sets: the documented capacity of what's there against what the new program asks of it
- The corrections list as an engineering document: each failure tied to the calculation or code section behind it, so the fix is a design change, not an argument
How to Buy It Well
Ask a structural stamp service how it handles delegated components: does it publish design criteria for the specialty engineers, and does it review their submittals against them? And ask the responsible-charge question plainly — who reviewed this set, and what did the review change? The answers separate a review firm from a seal vendor.
Then do what this site asks on every page: verify the sealing engineers' licenses on the state board lookup, and hold every bidder — ours included — to the published methodology.

Who Publishes This Directory
Published by Apex Grid Engineering PLLC. The firms evaluated and listed on this site today are the publisher's own family of brands — this is an affiliated directory, not a neutral referee. The methodology below is the standard any engineering firm can be measured against, and it is the standard we hold our own firms to in public. Presentation order on this site is the publisher's choice and an experiment in what helps buyers decide — it is not an objective quality verdict, and no firm pays for placement. Coverage claims are limited to licensure the operator's bench actually holds, stated per state. No reviews, ratings, or project claims are published for any firm unless they can be documented — the evaluations on this site are methodology assessments by the publisher, not customer reviews, and you will find none invented here.
