Professional Engineering Sealing
Professional Engineer review, certification, and sealing of drawings and calculations — mechanical, structural, and piping disciplines across multiple states.
Licensed Review and Certification
Grey Engineering Enterprises provides Professional Engineering sealing for drawings and calculations in mechanical, piping, and structural disciplines. Our licensed PEs perform genuine engineering review — not rubber-stamping — verifying code compliance, load paths, and design assumptions before a seal is applied.
Multi-State Coverage
We maintain PE licensure across multiple states and can obtain reciprocal licensure where a project requires it, keeping permitting on schedule for clients working across jurisdictions.
Typical Sealing Scopes
Pipe support drawings and calculations, pressure vessel and piping calculations, equipment anchorage designs, structural modifications, and fabrication drawings for code-governed equipment.
Common questions about PE Sealing
What is Professional Engineering sealing and when is it required?
Professional Engineering (PE) sealing is the act of a licensed Professional Engineer reviewing, approving, and affixing their seal and signature to engineering drawings or calculations, certifying that the work meets applicable codes and standards. PE sealing is required by law for pressure vessel and piping designs submitted for permits, structural modifications to buildings and industrial facilities, equipment anchor designs in jurisdictions with seismic or wind requirements, and any engineering work that affects public safety.
What disciplines does Grey Engineering seal?
Grey Engineering Enterprises provides PE sealing for mechanical and piping disciplines — pipe stress analysis reports, pressure vessel calculations, pipe support drawings — and structural disciplines including foundation designs, equipment anchor calculations, and structural steel drawings. Our licensed PEs perform genuine engineering review before any seal is applied.
Can you seal drawings in multiple states?
Yes. Grey Engineering maintains PE licensure across multiple states and can obtain reciprocal licensure where a project requires it. Multi-state licensure keeps permitting on schedule for clients with facilities in different jurisdictions without requiring them to engage separate engineering firms for each state.
