The Phase 1C upgrade at Honouliuli Waste Water Treatment Plant (WWTP) is introducing a new thermal hydrolysis system designed to “cook” biomass before it enters the digesters, increasing biogas production and creating more fuel that can be recycled into plant operations. ♻️

Our scope includes work across the boiler building, heat exchanger yard, digesters, generator building, and plumbing and HVAC systems. Now several years into the project, we are about 1/3 of the way through construction, with major installations at the boiler and heat exchanger buildings nearing completion, and work at digester #3 getting underway.

The project is expected to continue through approximately 2030, supporting long-term improvements to the plant’s energy efficiency and operations.

Our Healthcare team replaced two cooling towers and redid the associated piping at Kaiser Permanente Moanalua Medical Center in Honolulu, HI. 🏥🏗️

The work required careful coordination around a roof replacement and the installation of new steel supports by other teams all while the busy hospital remained operational. We are currently repairing the third cooling tower.

The new and improved LAX Terminal 5 spans more than 300,000 square feet across the Headhouse and the Concourse and will feature approximately 30 gates, enhancing the passenger experience at one of the nation’s busiest airports. 🛫

We were awarded the plumbing scope for the Headhouse and broke ground this past May with the installation of the project’s deepest utility—a 12-inch sewer line buried 14 feet below grade.

Additional underground plumbing systems include storm drain, waste and vent, grease waste, and subsurface drainage, laying the foundation for the next phase of construction. 🪏

Heathcock Hall is a new 81,700-square-foot academic laboratory building at UC Berkeley that will support the university’s chemistry students, faculty, and research staff. 🏫

Our scope includes the installation of mechanical piping and ductwork throughout the facility. One of the project’s most complex challenges was the limited rooftop footprint which required precise engineering and installation of heat pump chillers, double-stacked air handling units, and exhaust recovery systems.

Working in the heart of UC Berkeley’s active campus during the academic year demanded detailed planning, coordination, and ex*****on to safely complete the work while minimizing disruption in a busy urban environment.

Our team has successfully completed the rooftop equipment installation, marking a major milestone as the project moves toward startup this September. 🎯
