What is a PE stamp (and when do you need one)?
A professional engineer seal means someone licensed in that state took responsible charge of the sheets.
A PE stamp certifies that drawings or calculations were prepared, or reviewed closely enough, under a licensed engineer’s responsible charge. Building departments ask for it on structural, electrical, mechanical, fire-protection, and civil work that sits outside the prescriptive path in the code.
The stamp is not a graphic. The engineer checks the adopted code edition, local amendments, and whether the calculations match the sheets, then applies a seal, signature, and date in the form that state board allows. If the checklist says “engineer’s stamp,” the license has to be active in the project state.
Kevin Engineering matches that license from an office in Stafford, Virginia. Read the state guides for what a particular department tends to mark up, or start a quote if the set is already drawn.
State licensing for permit packages
The project address picks the license. The office address does not.
Professional engineers are licensed by state boards. A license from another state does not seal a permit set. Comity does not create an exception for a PDF uploaded from somewhere else.
Each eastern project is routed to an engineer with an active license where the work will be permitted: New York, Massachusetts, Florida, or another state east of the Mississippi, including Washington, D.C. The license is checked with the board before a seal is applied.
Work west of the Mississippi is outside this practice. So is Canada. If a set spans two states, say so in the quote so each portion is sealed by the right license.
How Kevin Engineering quoting works
Sheet count sets the stamp price. Square footage sets the drafting price. A visit is a flat add-on.
PE stamping uses one volume rate for the whole set. The rate drops as the page count grows, from $100 per sheet down to $25 per sheet. Enter the number of pages or pick a sample plan. Uploading the files is optional.
Rush adds 40 percent and emergency adds 80 percent, and both apply to the sheet total only. An on-site survey is extra and is not multiplied by rush: $450 for residential or solar, $650 for other projects, and $850 for commercial, plus about two business days.
CAD drawings are priced by square footage, not by the stamp rate. The number you see is a general estimate. Final pricing is confirmed after the plans are reviewed.
When an on-site survey belongs on the quote
Walk the property when the existing building, grades, or equipment are not on the drawings.
A desk review can only seal what the sheets show. Add a visit when a wall removal depends on a foundation that was never drawn, when grades for a retaining wall are guessed, or when rooftop equipment is missing from the survey.
An engineer walks the property and the findings come back with the review. The fee is flat by project type, and the schedule picks up about two business days. Turn the visit on in the live quote before you submit so the total and the date both include it.
Preparing a cleaner permit set
Title block, code edition, calculations, and one discipline per sheet group.
Put the project address, the jurisdiction, and the code edition in the title block. Separate structural, mechanical, electrical, and plumbing when you can. Include the calculations the department will ask for, and mark this as a resubmittal if you already have comments.
Name the city, not just the state. Digital-seal rules and energy forms change by department. A cleaner package is reviewed faster and comes back with fewer loops after plan check.
