BAE System’s specialized testing and manufacturing facilities support critical space missions, including the James Webb Space Telescope (JWST) program. The 4,042-square-foot clean/non-destructive test lab was developed to thoroughly clean and test critical flight hardware for national asset programs. As the next-generation Hubble Telescope, the infrared JWST enables astronomers to study the entire history of the universe. The lab’s built-in flexibility accommodates testing and cleaning for other satellite missions as well.

The lab’s large parts spray room, where bulkier flight hardware is cleaned with hazardous solvents, features an innovative air-diffusion system that delivers evenly distributed, cleanroom-quality airflow. This system moves vapors away from staff and limits flammability risks. Building Information Modeling (BIM) software was used to design large, complex ductwork for the small ceiling plenums in the spray rooms. Additional safety measures include applying intrinsically safe process piping controls to limit voltages in the presence of flammable vapors and developing a chemical container emergency depressurization system.

As the project’s mechanical and electrical engineer, RMH designed custom air systems to address the limited plenum space. The design incorporated vertical unidirectional airflow using fan-filter units, a custom hood, hazardous exhaust systems, and point-of-use laboratory systems, including nitrogen, house vacuum, deionized water, and dust collection. Electrical systems included electrostatic discharge protection, heavy power for support equipment, photosensitive “yellow” lighting, branch grounding, and overhead hoist electrical systems.

RMH provided mechanical, electrical, and lighting design services for a high-performance cabinetry manufacturing facility featuring 80,750 square feet of production space, 97,000 square feet of warehouse, and 22,300 square feet of administrative offices.

To safely manage large volumes of combustible wood dust generated during production, RMH engineered a 1,800-linear-foot dust collection system with 50,000 CFM capacity. The system captures heavy wood particles at 47 high-velocity pickup points and delivers them to an exterior baghouse. During the winter, the system reclaims heat by returning filtered air to the building.

To mitigate explosion risks, multiple infrared spark detection and suppression devices within the ductwork are integrated into the design. At the baghouse, RMH designed a pressure-sensitive detection and chemical suppression system to enhance safety and compliance.
Our team also designed a 2,350-square-foot, Class I, Division 1 paint vault equipped with a hazardous exhaust system, specialized grounding, and dedicated power and lighting systems to support safe and efficient operations.

The expanded Level III Neonatal Intensive Care Unit (NICU) at St. Francis Medical Center offers an exceptional level of care for infants born before 32 weeks of gestation, those weighing less than 3.3 pounds, or critically ill babies who require breathing assistance. The expanded NICU includes several enhancements:

  • Increased capacity from 30 to 46 beds
  • Two couplet rooms, allowing mothers and their babies to stay together while receiving expert, round-the-clock care. At the time, the St. Francis Medical Center’s NICU was the only one in Colorado and only the fourth in the nation to feature couplet rooms.
  • Additional space for caring for multiples, such as twins and triplets
  • Advanced room lighting designed to support and stimulate infants’ circadian rhythms
  • A family sleeping area with privacy partitions and fully private restrooms
  • An outdoor patio and wellness garden
  • A NICU family lounge for families of patients to connect with others in similar situations
  • A dedicated breast milk storage room
  • A family pre-discharge room to help parents prepare for returning home

The NICU expansion was the first phase of a multi-part project comprising 168,000 square feet and costing $102 million. This project also included a new emergency department, operating rooms, antepartum rooms, and space for future growth. RMH is serving as the project’s mechanical and electrical engineer, as well as the lighting designer.

BYU-Idaho is Idaho’s largest private University, sitting on a 430-acre campus with a district heating loop providing space heating for 40 buildings. RMH served as mechanical, electrical, and controls engineer for this project to add cogeneration capabilities to the Rexburg campus heating plant. The University replaced its coal-fired boiler plant with a new, multi-leveled heating plant containing a combined heat and power (CHP) system using natural gas. The project began with a conceptual study/economic analysis, which investigated the economic viability of adding cogeneration capabilities.

After completing the conceptual study and economic analysis, RMH designed the installation of a nominal 5.7MWe natural gas turbine with a 50,000 pph HRSG, which has a calculated simple payback of eight years. RMH’s design for the gas turbine featured a fully enclosed evaporative cooling system to increase the turbine output, as well as a turbine enclosure heat reuse system.

This project advances high-power electric vehicle (EV) charging by developing a megawatt-scale battery emulation framework at the Flatirons Campus. The system enables real-time testing of EV charging scenarios, focusing on integration with renewable energy and grid infrastructure.

At its core is a custom-designed MWh-scale lithium-ion battery emulator that replicates the dynamic behavior of various battery chemistries used in heavy-duty vehicles and stationary storage. Using Digital Real-Time Simulators, hardware-in-the-loop techniques, and grid simulators, the team built a robust platform for evaluating charge/discharge cycles and system-level interactions.

This infrastructure supports research in Vehicle Grid Integration, Behind-the-Meter assets, and Distributed Energy Resource applications, paving the way for more innovative and resilient EV-grid ecosystems.

RMH provided comprehensive electrical, mechanical, and plumbing engineering services for a new 43,000-square-foot, two-story facility supporting global scientific field missions. The building, more than twice the size of its 1970s predecessor, includes offices, electronic and wet laboratories, an ITAR-controlled warehouse, and connects to two existing aircraft hangars.

Both hangars support NCAR’s Gulfstream V and C-130 research aircraft. RMH’s electrical design scope included:

  • Upgrading Hangar A’s electrical service from 120/208V to 277/480V
  • Power and lighting design for a new locker room in Hangar B
  • Integrated lighting and controls design throughout the facility

This facility enhances NCAR’s ability to support airborne research and innovation worldwide.
