The Local 12 Training Trust main office was completed in April 2004. The Training Trust main office is equipped with eight state-of-the-art classrooms, each with its own drop-down projector and screen.

The Whittier shop (located next to the main office) is a nine-bay facility where major equipment repair and maintenance is done for all six Southern California heavy equipment operator training schools.

Located in San Bernardino County, Local 12's Devore heavy equipment operator training school is the largest of the six in Southern California. The others are located in San Diego, San Luis Obispo, Ventura, Whittier, and Bakersfield. The Devore training site offers more than sixty pieces of equipment, and much of our equipment fleet has been upgraded recently, including our new 2007 D8T. Local 12 crane certification and testing is offered at the Devore training site on boom truck, hydraulic, and lattice.
