Gilbane Breaks Ground on SoCal Campus Annex

By Eric Althoff

NORTHRIDGE, Calif.—General contracting firm Gilbane Building Company has broken ground on a new annex educational facility for California State University, Northridge.

As designed by Gensler, the 62,000-square-foot, $43.4-million Sierra Annex will be cited adjacent to the existing Sierra Hall. Sierra Annex will be home to a 3,000-square-foot main lecture hall, seminar rooms, classrooms and a few additional lecture halls. Gensler’s design incorporates natural lighting, and the hall’s flow of space is meant to encourage collaboration. The classrooms are also designed to be flexible such that they can be adapated for multiple uses.

Gensler and Gilbane previously collaborated on CSUN’s Associated Students Sustainability Center, which came online in 2017. In a recent announcement on the firm’s website, Gilbane’s area manager Raul Rosales said that his company enjoys a long-term working relationship with CSUN and Gensler, and thus this project offered an opportunity to continue such a collaboration.

“We are excited to be working on this inspiring project that will not only be an iconic building on campus, but improve the student’s academic experience as well,” he said.

The Sierra Annex is scheduled to debut for the fall 2023 semester, with additional work to be completed sometime in 2025.

Gilbane was founded in 1870 and remains a privately run, family-operated firm, with nearly 50 offices worldwide. Their Los Angeles office has been engaged in the Sierra Annex project.
