MEP Engineering Design,
Delivered Under Your Seal.

CoreX is the production engine behind engineering, AE, and design-build firms. We deliver coordinated, code-compliant HVAC, electrical, and plumbing construction documents in your standards — prepared for efficient review and sealing by the licensed Engineer of Record on your project. Under the agreed white-label workflow, your firm’s identity stays front and center while CoreX remains out of the client-facing deliverables.

Behind Your Brand

Your Seal, Your Brand — We Work Behind the Scenes.

White-label MEP is production capacity behind your firm — not a hand-off of responsibility. We work in your title block, CAD/Revit standards, and basis of design, then return a complete, coordinated HVAC, electrical, and plumbing set with traceable calculations and the applicable code-compliance path documented for your project and jurisdiction. Your firm stays client-facing while the project’s licensed Engineer of Record reviews under responsible charge and seals the final documents.

Behind the Scenes

From cover sheet to PDF metadata, client-facing deliverables are prepared to read as your firm's own within the agreed white-label workflow.

  • CoreX branding does not appear on the cover sheet, title block, or revision block — the set carries your firm's identity
  • PDF and CAD/Revit file metadata, authoring fields, and properties are cleaned to your standards before delivery
  • CoreX prepares technical response packages for your engineer of record to review and issue — official plan-review determinations remain with the AHJ or its authorized reviewer
  • We do not contact or market to your client unless your firm expressly authorizes direct project communication
  • We produce natively in your sheet templates, layer/CAD standards, and Revit families so the set reads as your own
  • We'll sign your NDA before any files change hands, and your client list stays confidential

Built for Your PE to Seal

The licensed engineer of record on your project can only seal what they can stand behind — so we deliver the calculations and the compliance path written out, not just drawings.

  • Load calculations and the basis of design are written out and traceable, so your reviewer audits the engineering, not just the linework
  • The code-compliance path is documented to the AHJ's adopted editions, per jurisdiction
  • Independent in-house QA/QC runs before any set reaches your reviewer, catching coordination and code issues early
  • Your firm sets the basis of design and directs the work; the project's licensed Engineer of Record reviews under responsible charge and seals the final documents
  • CoreX provides design-production support and does not replace the project's Engineer of Record

White-Label MEP — Common Questions

Quick answers about how white-label design support works behind your firm.

Under the agreed white-label workflow, CoreX branding does not appear on the cover sheet, title block, revision block, or client-facing PDF/CAD/Revit deliverables. We do not contact or market to your client unless your firm expressly authorizes direct project communication. We'll sign your NDA before any files change hands, and your client list stays confidential.

The licensed Engineer of Record designated for the project is responsible for reviewing and sealing the final engineering documents. Under this white-label service, CoreX provides design-production support and documented calculations, basis-of-design information, and a code-compliance path for that licensed engineer to review under responsible charge. CoreX does not seal or stamp drawings and is not the engineer of record. CoreX does not replace the project's Engineer of Record, and does not provide or arrange the sealing engineer.

Yes — that's the core of white-label. We produce natively in your sheet templates, title block, layer and CAD standards, and Revit families and worksets, so the set reads as your own and is prepared to integrate into your project. Send us your standards package and a sample set up front; we'll match it sheet-for-sheet. File metadata and authoring fields are cleaned to your conventions before delivery.

We write out the load calculations and basis of design and document the code-compliance path to the AHJ's adopted editions — IBC, IMC, IECC, ASHRAE 90.1 and 62.1, NEC, IPC/UPC/NSPC, and IFGC/NFPA 54 — rather than handing over drawings alone. Independent in-house QA/QC runs before anything reaches your reviewer. That gives the licensed engineer of record on your project a documented, auditable basis to review under responsible charge before sealing.

Yes. We review AHJ comments, contractor RFIs, and submittal questions; prepare the technical response package; and revise affected sheets, calculations, schedules, and supporting narratives. For white-label work, the package follows your templates and agreed communication workflow. Your engineer of record reviews and issues the response; official plan-review determinations remain with the AHJ or its authorized reviewer. Any required professional seal or jurisdiction-specific Engineer-of-Record sign-off remains with the appropriately licensed Engineer of Record.

White-label and outsourced aren’t alternatives: white-label is whose brand the set carries, outsourced is how the capacity is supplied, and one engagement can be both. See how outsourced capacity works →

Client Testimonials

What Our Clients Say About CoreX

"When our workload grew, CoreX let us scale up without the quality dropping. They communicate clearly, they meet their deadlines, and their sets are detailed enough that our engineers and our clients both trust them."

Managing PrincipalMEP Consulting Firm, North Carolina

"Their work has been better than we expected, and it has stayed that way. Their certified HVAC and plumbing designers know the code, think about how the job will actually get built, and coordinate across disciplines. At this point they work like part of our own design team."

Senior Project ManagerMEP Consulting Firm, California

"CoreX has become a dependable production partner on our commercial work. HVAC, plumbing and electrical come in coordinated, clearly documented and on time. They understand how a U.S. consulting firm runs, so they fit our workflow instead of us adjusting to theirs."

OwnerMEP Consulting Firm, Illinois

"What impressed us most is their discipline. They follow a real design process and raise coordination issues early, before they turn into problems. Their electrical team is responsive and careful with code. Their sets need noticeably fewer review rounds, and our internal QA runs much more efficiently because of it."

Director of EngineeringMEP Consulting Firm, California

"CoreX delivered our HVAC package ahead of schedule without cutting corners on quality. They were thorough and quick to respond, so coordination with our team was easy and we had fewer revisions during design. We’d recommend them without hesitation to any MEP firm looking for a dependable partner."
