Wyoming-Registered LLC

The MEP Engineering Partner Behind Your Best Projects.

We handle the MEP design production, so you can focus on your client relationships.

Every project is engineered like it’s going to be reviewed — so well-coordinated that the set answers the questions the field would otherwise ask.

How We Operate

Standing Tall With Our Clients From Design Through Construction

A structured three-phase approach ensuring precision, accountability, and seamless delivery — from the first engineering session through construction support. Your licensed engineer of record makes the design decisions and seals the set; CoreX does not seal or stamp drawings.

01
Pre-Design

The phase that makes everything else easy

Before engineering begins, clarity comes first. Our pre-design phase removes guesswork — aligning goals, surfacing coordination gaps, and setting a clear roadmap so every discipline moves forward with confidence and fewer surprises.

Architectural & consultant plan review Existing site condition review from client-supplied data As-built & existing documentation review Early identification of hidden conflicts & coordination risks Identification of design gaps & missing criteria Project kickoff & scope alignment Identifying project points of contact for seamless communication & coordination Code, standards & jurisdiction compliance review Confirming the client’s preferred equipment vendors Finalizing project submission dates with the client
◆ The CoreX Pre-Design AdvantageBecause we ask the right questions before design begins, our sets go to plan check with the reviewer’s usual questions already addressed — aiming for fewer plan-check comments, fewer construction-phase RFIs, and fewer weeks lost to resubmittals.
02
Design

Designed with clarity, built on a strong foundation

Once the approach is agreed with your engineer of record, our team carries the design through — sizing each in-scope system, coordinating across trades, and producing permit-ready deliverables that meet code and quality standards while minimizing rework.

Load calculations, equipment sizing & final specifications Detailed engineering across all in-scope MEP disciplines Equipment layout and coordination across all trades BIM/CAD modeling & system layout development Utility coordination and service planning Thorough QA/QC review before every submission Energy-code compliance documentation — COMcheck reports, California Title 24 Part 6 forms produced in CEC-approved software, and jurisdiction-specific formats — prepared for your engineer of record to submit Clash detection & system conflict resolution
◆ The Design Outcome: A Set Prepared for Review and Permit SubmissionClean, coordinated, construction-ready documents — calculations checked, in-scope trades aligned, and the full set prepared for your engineer of record to review, seal, and issue for permit submission.
03
Post-Design

Fewer questions from the field — and answers when they come.

Our commitment doesn’t end at submission. CoreX remains engaged during permit review and construction, providing remote technical support within the agreed scope.

RFI responses and construction-phase technical support Equipment submittal and shop drawing review Plan review responses and resubmission sets, prepared for your engineer of record to issue
◆ The Post-Design Commitment: Support Through ConstructionThrough permit review and construction, CoreX prepares responses to RFIs and field questions for your engineer of record to issue, through to the Certificate of Occupancy.
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."
