Medical gas systems — oxygen, medical air, vacuum, nitrous oxide — require NFPA 99-compliant engineering, licensed medical gas installers, and third-party inspection before use. We produce the permit drawings and coordinate the third-party verification.
Request Engineering SupportApex Grid Engineering is licensed in 49 states — every U.S. state except Alaska. Engineering stamping and licensure are confirmed for each project jurisdiction. We engineer plumbing engineering scopes as a standalone service or as part of a coordinated structural, MEP, civil, and geotechnical package.
We work from architectural PDFs, contractor sketches, or existing CAD files and produce stamped engineering documents, permit drawings, and calculations that building departments accept the first time.
