PE Stamps for As-Built and Record Drawings: What Can Be Certified?
Understand the difference between as-built, record, and verified drawings—and what evidence an engineer needs before signing or sealing them.

Key takeaways
- Record drawings should identify the source and limits of information about completed construction.
- An engineer cannot responsibly certify concealed conditions without a reliable basis.
- Field observations, contractor markups, testing, and surveys should be coordinated before final documentation.
As-built does not always mean independently verified
The terms as-built and record drawing are often used interchangeably, but their meaning can vary by contract and jurisdiction. A contractor may mark changes made during construction, while a design professional may prepare a record set from those markups and available observations.
The title block, certification language, and project records should accurately describe what the engineer knows. Broad statements that imply continuous observation or verification of concealed work may not be supportable.
Evidence to collect before engineering review
The review scope should connect each claimed field condition to a reliable source. When the available evidence is incomplete, additional survey, testing, selective exposure, or contractor documentation may be required.
- Approved permit drawings and all issued revisions
- Dated contractor redlines and change documentation
- Survey data, inspection reports, photographs, and test results
- Requests for information and approved substitutions
- Field-observation reports and documented concealed conditions
- The exact certification requested by the owner or authority
Define the final deliverable carefully
Before requesting a seal, confirm whether the authority wants record drawings, a letter, a limited field-verification report, or revised design documents. The engineer should state assumptions and exclusions so the delivered document does not claim more certainty than the evidence supports.
Frequently asked questions
Can a PE stamp contractor-prepared as-built drawings?
Only after performing the review and verification required by the jurisdiction and the facts of the project. Contractor markups alone may not establish every field condition.
Can concealed construction be certified after completion?
It depends on the available records and whether suitable testing or investigation can establish the condition. The engineer should not make unsupported certifications.
