Los Angeles Trade Tech College

Los Angeles Trade Tech College was founded in 1925 as the Frank Wiggins Trade School and is the oldest of the nine public, two-year colleges in the Los Angeles Community College District.

Cannon provided civil engineering plans, specifications, and estimates for the Construction Technology Building (CTB), as well as the associated, six-level 24th Street Parking Garage. The CTB was designed as a three-story, 139,000 square-foot training center—the largest building on campus. Cannon also provided on-site and off-site infrastructure improvements for utility relocation, street vacations, and intersection improvements.

The project included a construction yard, two public street vacations, and street rehabilitation to support this new facility. Roadway infrastructure improvements included Grand Avenue street rehabilitation as well as new curbs, sidewalks, pedestrian crossings, and traffic signal modifications. To facilitate needed relocation of existing water and sewer lines in 22nd Street, 23rd Street, and Olive Street, Cannon first prepared a sewer capacity study. The 22nd Street work involved relocating 600 feet of existing 8-inch, on-site sewer line and up-sizing 900 feet of existing 8-inch sewer line to 12-inch.

The project provided accessibility features in the building interiors and in the path of travel allowing equal physical access for students, personnel, and visitors. Equal accessibility enabled students to fully participate in college programs, services, and activities. As part of the project, Cannon prepared grading, sewer, domestic water, and fire water plans, as well as a storm water pollution prevention plan, and off-site public improvements. The project required approval through the City of Los Angeles’ Bureau of Engineering and the Bureau of Sanitation, as well as review and permitting by the City of Los Angeles Department of Transportation, Department of Education, and Department of Water and Power.
