The question you shouldn't have to ask out loud.
Every PE who considers this arrangement has the same private question: "Can I lawfully seal work these engineers touch — or is this plan stamping?" It deserves a direct, public answer, so here it is, before the sales call ever happens.
What responsible charge actually requires
Licensure law across the states converges on the same structure: a licensed engineer may seal work prepared by unlicensed personnel provided the work was prepared under the licensee's direction and supervision — with the licensee directing the work throughout its preparation, having input before anything is finalized, and holding full authority to change it. What the law prohibits is the opposite pattern: reviewing and sealing work that someone else prepared independently. That's plan stamping, and boards discipline for it.
Why the seat model satisfies it — and mailed-back offshore work doesn't
A project shop that takes your files, produces plans overseas, and mails back a finished set puts your PE in exactly the posture boards warn about: reviewing completed work after the fact. A StoneBrief seat inverts that. Your engineer works inside your environment, takes direction from your PE or PM throughout preparation — morning queue, midday check, redlines, end-of-day note — and produces nothing your reviewer didn't direct. The supervision isn't retroactive paperwork; it's the literal daily workflow.
What our engineers never do
They do not exercise independent design judgment. They do not sign or seal anything. They do not represent your firm to clients, agencies, or reviewers unless you explicitly ask. They do not make the calls — they draw the calls your PE makes. The C-SEAL layer stays frozen to us permanently, by law and by design, and we'd walk away from any client who asked us to thaw it.
The boundaries we'll name before you find them
Two, honestly stated. First: certain public contracts — some DOT and agency work — carry domestic-work or data-handling clauses; seats serve your private-sector book, which for most land development firms is the book. Second: responsible charge requires that your PE actually has bandwidth to direct the work. If your review capacity is already past its limit, one more producer makes that worse, not better — and we'd rather tell you that on the scoping call than discover it in week two.
