Union Station


Los Angeles, California




Dunbar Architects


160,000 Square Feet





Los Angeles Union Station was commissioned in 1933 and is known as “the last of the great train stations.” As the largest railroad passenger terminal in the Western United States, the concourse building encompasses 161,000 square feet, and the station property is upwards of 5.9 million square feet. SCEG, over the course of multiple different projects, provided mechanical, electrical and plumbing engineering.

These included a historic renovation in the ticketing concourse, drainage systems within the passenger tunnels, and HVAC for the Fred Harvey building and the security operations center. Also in progress by SCEG is a massive undertaking to compile nearly 100 years’ worth of original and renovation plans into a single digital record drawing. Using laser scans to create a 3D database and layered geometric real estate property the model encompasses all real estate and fixed objects. 

The model includes HVAC systems, electrical power, data and lighting, plumbing pipes, pumps, fixtures and drains. Furthermore, the project includes integration with the Internet of Things (IoT) technology allowing for click-thru features of model artifacts providing general and specific details including structure history, manufacturer, designer, parts reorder process, and maintenance schedule.
