California’s largest lake, the Salton Sea, has been shrinking for decades, exposing toxic sediments and endangering wildlife and human health. The Salton Sea Species Conservation Habitat Project addresses this crisis by creating 4,000 acres of restored wetland habitat to combat hypersaline conditions, revive aquatic life, and restore critical bird migration routes.

RMH provided electrical and controls design for the prime consultant Knight Piesold. The electrical design included power, grounding, and lighting for the saline pump station, flood buffer pump station, and O&M building, along with a new utility service, medium-voltage distribution, circuit breaker coordination, arc flash study, and back-up power (UPS) for critical instrumentation. RMH designed a new site-wide control system, integrating pump station controllers and up to 50 process instruments, and provided logic diagrams, motor control center schematics, and site security design for a CCTV system.

Key highlights of the project include a gravity-flow system; mixing channels and sedimentation ponds for optimal water quality control to maintain salinity between 20 g/L and 40 g/L; variable speed pumps and removable diffuser pipes for flexible salinity management; and a design that allows for potential high-intensity rainfall events, minimizing upstream impacts and protecting agricultural land.

Wells Concrete’s new Brighton facility consolidates two existing Denver locations into a single, comprehensive manufacturing operation to enhance production capability and flexibility for the Denver market. The 122,673-square-foot precast facility sits on 64.5 acres and features year-round indoor production capabilities for architectural precast and outdoor structural forms, with lifting capacity upgraded from 15-ton to 25-ton cranes to accommodate larger products and higher volumes.

The manufacturing facility incorporates long-line prestressing forms and an expanded inventory of movable forms to meet diverse project demands. The versatile production facility enables identical product manufacturing with consistent quality while maintaining flexibility to meet demanding schedules and minimize project risk. The specialized facility includes a 4,500-square-foot mold shop, steel shop, lunchroom, office, maintenance bays, boiler and air-compressor room, production area, beam bed/storage area, tool room, QC lab, chemical storage area, and washroom.

As the project’s mechanical and electrical engineer, RMH provided mechanical and electrical design and construction-phase services for the new concrete pre-stress plant. Services included chilled water, steam, compressed air, power, and natural gas systems to support the specialized manufacturing operations.

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.

The Lockheed Martin Space Systems Gateway Center at the Waterton Canyon campus marks a significant leap in satellite production capabilities. This $350 million, 266,000-square-foot facility focuses on designing, manufacturing, and testing satellites. Within its expansive layout, 175,000 square feet of SCIF support secure operations for national security missions.

The Gateway Center features a high bay Class 100k clean room, enabling the simultaneous construction and testing of large and small satellites. It also houses a large thermal vacuum chamber that replicates the harsh conditions of space, allowing for rigorous satellite testing prior to launch. Complementing these facilities is a sizable anechoic chamber for safely testing satellite antennas, sensors, and communication systems, as well as a large volume airlock that streams the departure of completed spacecraft in a controlled, clean environment.

The project includes redundant power systems, uninterruptible power supplies, generators, and a central utility plant, achieved through meticulously coordinating highly technical equipment.
