How Do Architects Engage an Engineer of Record for Review-and-Seal?

By Jeremy Mills, CEO & Founder, Apex Grid Engineering — USAF Veteran. · Updated 2026-09-15

Architects engage an EOR by contracting a licensed PE to take responsible charge of the engineering scope — reviewing the design, verifying calculations, requiring revisions, and sealing the set. Define the scope in writing at engagement and bring the EOR in early, when review findings are still cheap to act on.

I'm Jeremy Mills, CEO & Founder of Apex Grid Engineering and a U.S. Air Force veteran. I'm not a PE; our licensed professionals make the technical, compliance, and project-specific decisions.

Two ways architects use an EOR

The first model is the EOR as design partner: the architect engages the structural or MEP engineer at project inception, the engineer designs the systems through the phases, and the seal at permit time covers work the PE authored. This is the smoothest path — responsible charge is natural because the PE did the work, coordination is continuous, and there are no surprises at the end. Most established architect-engineer teams work this way, and the fees reflect a full design scope. The second model is the EOR as reviewing engineer: the design exists — produced by the architect's staff, a design-build entity, or a previous engineer — and the PE is engaged to review it, verify the calculations, require revisions, and seal. This is the true review-and-seal engagement, and it is where the discipline matters most: the PE must actually review, not just read. I take these engagements seriously and price them for the review effort they require, because a reviewing EOR who finds real problems is doing exactly what the owner paid for. Architects should expect the review to produce revision comments — a review that finds nothing on a complex set was not a review.

Coordinating the EOR through design phases

The coordination rhythm I recommend: the EOR reviews the structural system selection and MEP concept at schematic design, when the architect is choosing between systems and the engineer's input actually changes the building. At design development, the EOR verifies preliminary sizing and the coordination assumptions — floor-to-floor heights against duct depths, structural bays against the program grid — because DD is where coordination failures get cast in concrete. At construction documents, the EOR performs the full review-and-seal: detailed code compliance check, verified calculations, marked revisions, re-review of corrections, then the seal. The architect's role in this rhythm is to feed the EOR reviewable packages at each milestone — not a Friday-afternoon PDF dump, but backgrounds, narratives, and decisions in a form the engineer can actually review. I also ask architects to include the EOR in the AHJ pre-submittal meeting or at least share the notes; the EOR who hears the reviewer's concerns firsthand seals a set that anticipates them. Coordination is not overhead — it is the mechanism by which the review stays ahead of the drawing set instead of chasing it.

Architect's EOR engagement checklist

Put these in place at contracting and the engineering scope stays clean through permit. • Written scope: phases, disciplines, deliverables, revision protocol, correction rounds included • Name the individual PE in responsible charge and verify the license (and Texas F-number) in the project state • Engage at schematic design — the EOR's early input on system selection is the highest-value engineering on the project • Deliver reviewable packages at each milestone: backgrounds, narratives, geotechnical report, AHJ checklist • Define who revises and who re-reviews, so plan-check corrections do not trigger a scope argument mid-permit

What else do project teams ask?

What should the architect's EOR agreement spell out?
The phases covered, the disciplines included, the deliverables (sealed drawings, calculation packages, energy compliance documentation), the revision and re-review protocol, how plan-check corrections are handled and how many rounds are included, the schedule milestones the EOR's reviews tie to, and which state's license (and firm registration, in Texas) backs the seal. I also recommend naming the individual PE in responsible charge, not just the firm — the board holds the individual accountable, so the agreement should too. Architects who put this in writing at the start avoid the mid-project renegotiation that kills momentum.
Can the architect seal the engineering themselves?
Only for engineering that falls within the architect's own licensed scope, which in most states is narrow — architects seal architecture, and engineering beyond incidental scope requires a licensed PE. The line varies by state and project type, but structural design of any significance and MEP system design sit squarely on the engineering side. When the building department's checklist calls for sealed engineering, the architect needs a PE. I have seen architects try to stretch their seal over engineering scope to save the owner a consultant fee; plan check bounces it, and the project loses more time than the fee would ever have cost.
Who hires the EOR — the architect or the owner?
Either arrangement works, and each has tradeoffs. When the architect hires the EOR as a subconsultant, coordination is tighter — the EOR answers to the design team — but the architect carries the fee risk and the liability chain. When the owner contracts the EOR directly, the architect loses some control over the engineering schedule but gains a cleaner liability picture. On design-build the GC often holds the EOR contract. I work under all three structures; what matters is not who signs but that the scope, the schedule, and the responsible-charge PE are defined in writing. Ambiguity about who hired the engineer never survives first contact with plan-check corrections.
What does the EOR need from the architect to start the review?
The backgrounds in a workable format, the design narrative and code analysis, the geotechnical report for structural scope, any owner-driven constraints (equipment preferences, budget targets that drive system selection), and the AHJ's submittal checklist. For MEP scope I also need the architectural reflected ceiling plans and the space program, because system routing lives or dies on ceiling space. The review can only be as good as its inputs — an EOR handed PDFs with no backgrounds and no narrative spends the first week reconstructing the design instead of reviewing it. Architects who deliver a clean package get a faster, cheaper review.
