“Stamp Only” vs. Review-and-Seal: What the Difference Means

The responsible-charge requirement is not a suggestion and it is not unique to one state. Texas TBPELS Rule 137.33, California Business & Professions Code 6735, Florida's 61G15 rules, and Arizona's Board of Technical Registration rules all require the sealing PE to have performed or directly supervised the work — and for drawings originated elsewhere, direct supervision means the full review sequence: complete review, independent verification, marked revisions, confirmed corrections, then the seal. Boards enforce this. A PE who seals without review risks reprimand, fines, suspension, or revocation, and the sealed documents can be challenged by any party that relied on them. The rules exist because the seal is a public-protection instrument, not a commercial product.

Our review-and-seal engagements follow the same sequence on every project. We take in the complete drawing set plus every piece of supporting engineering available — calculations, basis of design, geotechnical and survey data, equipment selections. The sealing PE reviews the set against the applicable codes, independently verifies the critical engineering (recalculating where the basis is unclear), and produces a marked revision list. Revisions are made and re-verified. Then — and only then — the PE seals, signs, and dates the set. The client gets sealed drawings ready for permit, backed by engineering a licensed professional evaluated and stands behind. That is what the search term "stamp only" is really asking for, delivered in the only form the rules allow.

Not every PE practices to the standard the rules require. Screen for these warning signs before you hire — each one indicates a practice that puts your project at risk. • Same-day or instant sealing promised with no mention of reviewing your drawings • No request for your calculations, basis of design, or supporting engineering data • A flat fee quoted with no questions about the project's size, discipline, or complexity • Sealing offered in a state where the PE is not licensed, or in a discipline outside their competence • Reluctance to describe the review process or put the review-and-seal scope in writing

These two reviews are routinely confused, and the confusion is expensive. Plan check is the review performed by the authority having jurisdiction — the city or county building department, or a third-party plan-review firm working for it — after a permit application is filed. A plans examiner checks the submission against the adopted building code, local amendments, zoning and life-safety requirements, and issues either a permit or a correction list. The examiner does not design the project, does not seal anything, and does not take professional responsibility for the engineering. A permit is the jurisdiction's permission to build; it is not a certification that the design is sound, and plan-check approval does not transfer design liability away from the engineer who sealed the drawings. The PE's review-and-seal happens on the other side of that counter, before submittal. The sealing engineer asks a different question than the plans examiner asks. The examiner asks: does this submission demonstrate compliance well enough to issue a permit? The PE asks: is this engineering actually correct — loads, load paths, sizing, connections, code basis — and am I prepared to certify it as my own responsible-charge work? That is why the two reviews catch different things, why a properly sealed set can still receive plan-check corrections about documentation, local amendments, or presentation, and why plan-check approval can never cure a seal that was applied without review.

For a clean, complete, single-discipline set — calculations provided, code basis documented, drawings internally consistent — review-and-seal commonly runs from several business days to about two weeks, most of that time being the PE's verification work rather than waiting. Multi-discipline commercial sets, sets with missing or thin calculations, and sets that need substantive revisions commonly run two to four weeks, because each round of marked corrections has to be drawn, returned, and re-verified before the seal can be applied. The drivers are completeness of the engineering basis, number of disciplines, recalculation required, and how fast the originating designer turns revisions around. Fees follow the work, so treat any number quoted before the PE has seen the set as a guess. As a typical range, a small, clean single-discipline review-and-seal often falls in the high hundreds to a few thousand dollars; a multi-discipline commercial set more commonly falls in the several-thousand-dollar range and rises with size, complexity, and revision cycles. What a client is buying is not the seal impression — it is the hours of a licensed engineer verifying engineering and standing behind it. A quote dramatically below those ranges, offered sight unseen, is not a bargain signal. It is evidence the review is not going to happen.

A representative case: a restaurant group hired a designer in another state to prepare drawings for a tenant improvement in Texas, then discovered at the permit counter that the structural and MEP sheets needed a Texas-licensed PE's seal. The owner asked for a stamp on the finished set. What the engagement actually required was review-and-seal under Texas Rule 137.33. The sealing PE reviewed the full set and the designer's calculations, verified the gravity and lateral loads for the new rooftop equipment, and found two genuine problems: a header carrying the new unit load had been sized without the equipment's operating weight, and the gas and condensate routing on the mechanical sheets conflicted with the reflected ceiling plan. Those findings were marked, the originating designer revised the sheets, the PE re-verified the corrections, and the set was sealed, signed, and dated with the firm's Texas F-number. The review added days, not months, and cost a fraction of a redesign — but it caught a load error that plan check, which reviews for code compliance rather than re-performing the design, might well not have caught before construction. That is the practical difference the distinction makes: the owner did not buy a stamp. The owner bought a second, accountable engineering pass that made the permit set defensible.
