Healthcare Facility MEP & Structural Engineering Services
Engineered Infrastructure for Hospitals, Clinics, and Medical Research Centers
Healthcare carries the most demanding regulatory and life-safety burden of any occupancy type. A single project must reconcile the FGI Guidelines, NFPA 99 risk-category requirements, ASHRAE 170 ventilation criteria, and jurisdictional review — often HCAI/OSHPD in California — while sustaining patient care in occupied buildings. Structural, mechanical, electrical, plumbing, and medical gas systems are tightly interdependent, so a change in one ripples through the rest, and fragmented coordination is where schedule and budget risk accumulate.
Apex Grid delivers structural, MEP, civil, and geotechnical engineering under one roof, sparing owners the coordination gaps that stall reviews and inflate change orders. We design essential-facility structures to Risk Category IV demands, size mechanical systems for the pressure relationships and air-change rates infection control requires, and produce permit-ready, sealed documents built to survive plan check. Veteran-owned and multi-state team; project availability and stamping are confirmed per project after individual license, firm authorization, discipline, and AHJ requirements are verified, we serve clinics through multi-phase hospital campuses.
Quick Answers
Healthcare engineering questions
What engineering disciplines are coordinated for Healthcare projects?
What information helps define a Healthcare engineering scope?
Which codes and standards may apply to Healthcare projects?
OSHPD & HCAI Compliance Expertise
Acute-care hospitals and skilled nursing facilities in California fall under HCAI (formerly OSHPD), which imposes its own plan review, special inspection, and construction observation beyond the base California Building Code. We design non-structural components — ceilings, ductwork, piping, and equipment anchorage — to ASCE 7 Chapter 13 with the Ip = 1.5 importance factor. Our documents anticipate the amended review process and package the special inspection and testing agreements HCAI requires, and early decisions on incremental versus full compliance keep occupied renovations moving.
NFPA 99 Certified Medical Gas & Vacuum Systems
Medical gas and vacuum systems are engineered to NFPA 99 by risk category, coordinating source equipment, alarm zones, and outlet loads with ASSE 6000-series requirements. We calculate diversified oxygen, medical air, nitrous oxide, and instrument-air demand; size copper Type L tubing for pressure drop at peak simultaneous flow; and locate zone valve boxes, area alarms, and master alarms per code adjacencies. Manifold and bulk-oxygen sizing and medical-vacuum redundancy suit the facility's procedure mix, and documents specify brazing, purging, and required third-party verification for commissioning.
Airborne Infection Isolation (AII) & Negative Pressure HVAC Design
Airborne infection isolation and protective-environment rooms demand precise, verifiable pressure relationships. We design AII rooms to ASHRAE 170 and CDC criteria: minimum 12 air changes per hour, 100% exhaust to the exterior, and negative pressurization of at least 0.01 in. w.c. relative to adjacent spaces, monitored continuously. Airflow offsets hold pressure with the door closed, anteroom sequencing is defined, and HEPA filtration is specified where recirculation or exhaust discharge requires it; protective-environment rooms are conversely positive. Low-leakage dampers and room-differential monitoring let commissioning verify compliance.
Integrated Discipline Scope for Healthcare Projects
One coordinated engineering team across structural, MEP, civil, and geotechnical — one point of accountability from concept through permit.
Structural Engineering
Hospitals are Risk Category IV essential facilities, so we design lateral and gravity systems to the elevated seismic importance factor and drift limits that keep the building operational after a design-level event. This drives system selection, foundation demands, and non-structural anchorage, and we coordinate imaging-suite shielding loads, heavy rooftop equipment, and vibration-sensitive areas.
Renovations in occupied hospitals require capacity checks, shoring, and load-path continuity so openings never compromise the structure.
- Risk Category IV seismic design to ASCE 7 with Ip = 1.5 non-structural anchorage
- Rooftop and interstitial equipment support framing and vibration isolation
- Imaging/radiation shielding wall and slab loading coordination
- Structural openings, infill, and shoring for occupied renovations
- Seismic joints and phasing details for campus expansions
MEP Engineering
Healthcare MEP carries the most code intensity. We design HVAC to ASHRAE 170 for space-by-space air changes, pressure relationships, temperature and humidity, and filtration across operating, isolation, and pharmacy spaces. Electrical distribution follows NEC Article 517, splitting the essential electrical system into life-safety, critical, and equipment branches with code-compliant generators.
Plumbing and medical gas are coordinated together, including sanitary, domestic hot-water recirculation for Legionella control, and NFPA 99 medical gas and vacuum.
- ASHRAE 170 ventilation, pressurization, and filtration design
- NEC 517 essential electrical system: life-safety, critical, equipment branches
- Emergency generator sizing, paralleling, and automatic transfer schemes
- Domestic hot-water and recirculation design for Legionella mitigation
- OR, sterile processing, pharmacy, and lab specialty exhaust systems
Civil Engineering
Healthcare sites accommodate ambulance circulation, covered patient drop-offs, service access, and helistop approach where applicable, all meeting accessibility and municipal standards. We design grading, ADA-compliant routes, stormwater detention, and utility connections sized for the facility's high domestic, fire, and medical-waste loads.
Fire-access lanes, hydrant placement, and site fire-flow are coordinated with the building fire-protection design.
- Emergency-vehicle circulation, drop-off, and service access design
- Site grading, ADA-accessible routes, and parking layout
- Stormwater detention and NPDES-compliant drainage
- Fire-flow, hydrant, and fire-access lane coordination
- Domestic, sanitary, and fire-service utility connections
Geotechnical Engineering
Essential facilities warrant a thorough subsurface program to establish bearing capacity, settlement tolerances, and seismic site class. We provide foundation recommendations — spread footings, mats, or deep foundations — and evaluate liquefaction and lateral spreading where site conditions require.
Recommendations address vibration-sensitive imaging areas, slab-on-grade support, and earthwork so the design rests on verified soil parameters.
- Subsurface investigation and seismic site classification
- Bearing capacity and settlement analysis for essential facilities
- Liquefaction and lateral-spread evaluation where applicable
- Deep foundation recommendations for poor soils
- Vibration and slab-support parameters for sensitive equipment

Codes & Standards We Design To
Healthcare projects live and die by code compliance. These are the standards our drawings and calculations are built around.
The Guidelines for Design and Construction set minimum programming, space, and system requirements for hospitals and clinics.
The Health Care Facilities Code sets risk-category requirements for medical gas, electrical, and gas-equipment systems that we design for third-party verification.
This ventilation standard defines air changes, pressure relationships, humidity, and filtration by space type for infection control.
Article 517 governs health-care electrical systems, including the essential electrical branches and patient-care-space wiring our distribution follows.
The building code and ASCE 7 establish the Risk Category IV loading and seismic criteria we apply to structural and non-structural design.
In California, HCAI enforces additional plan review, inspection, and observation for acute-care and skilled-nursing facilities.
