Featured experience

University of California San Diego Franklin Antonio Hall Engineering Center

The University of California San Diego’s new engineering center, Franklin Antonio Hall, is designed to facilitate interdisciplinary education and research. It features 13 “collaboratories,” allowing researchers from across campus to come together and develop innovative projects like 3D-printed, low-cost autonomous underwater vehicles and plant-based research on human vaccines.

University of California San Diego Central Plant Expansion

As part of its 30-year long-range development plan, the University of California San Diego expanded its central plant capacity with four 3,000-ton centrifugal chillers powered by electric water cooling.

This system provides 31,200 ton-hours of thermal energy storage to the main campus using an equally sized cooling tower, condenser, and chilled water pumps for each chiller. Additional capacity and related acoustical treatment will continue to meet the campus’ growing needs for years.

Sharp Mary Birch Hospital for Women and Newborns

To ensure the uninterrupted operation of the critical healthcare environment at Sharp Mary Birch Hospital for Women & Newborns, our team devised a comprehensive project plan to replace four air handling units (AHU). An AHU-7 in the second-level mechanical room serviced the perioperative surgery center, while three rooftop units supplied air to all patient floors.
