Campus construction and architecture
Caltech is small but prizes excellence and ambition, and that emphasis applies to architecture on the 124-acre campus as well as research and education. Here, you can find information about current construction and renovation projects, design honors, small business support, and the plans governing Caltech construction, with links to learn more.
Current projects
Please email [email protected] with any construction-related questions or concerns.
Caltech works to minimize any interference to traffic, parking, or quality of life caused by campus construction projects. However, we know disruptions are inevitable, and we appreciate your patience. Crews are required to follow city construction guidelines and safety protocols, and trucks use city-advised routes.
Ginsburg Center
Caltech is building the Dr. Allen and Charlotte Ginsburg Center for Quantum Precision Measurement, with completion expected in 2026.
"This new building will be a catalyst not only for scientific progress, but also for economic development and community enrichment throughout our region and beyond. I eagerly anticipate the breakthroughs the Ginsburg Center will make possible."
—Assemblymember Chris Holden, at the August 10, 2023, groundbreaking
The Ginsburg Center will expedite discoveries in multiple scientific fields and help students learn to collaborate at the rich interfaces of quantum physics, computer science, astronomy, and other fields.
We are working to keep traffic flowing smoothly as trucks travel to and from the site. Per city guidance, trucks exit the 210 freeway on Hill Avenue, travel to the site on California, and return via Wilson Avenue, Del Mar Boulevard, and Hill.
Please visit the Caltech Facilities website for further construction information, more in-depth updates, and FAQs.
Public meetings: We thank local and campus community members for coming to meetings and helping us refine plans to limit disturbance during construction. The City of Pasadena's Design Commission considered and approved the design, holding three public hearings. The Planning and Community Development Department approved a conditional use permit to build the Ginsburg Center after holding a public hearing. Caltech held a design and construction open house on campus in October 2023. These meetings included short presentations by Caltech Facilities Associate Vice President Dave Kang; Adaeze Cadet, an architect from HOK; and others.
Partner project on Green Street
The earliest phases of design and community engagement have begun for a building to be developed by Trammell Crow Co. on a Caltech-owned property. The site, a parking lot that Caltech is using as a staging area for Ginsburg Center materials, is on the south side of Green Street at Holliston Avenue.
The future building will support innovation and economic growth in Pasadena with a mix of office, lab, and digital resources to attract established bioscience businesses and nurture new ventures.
Be on the lookout for future community meetings; details will be shared here.
Traffic signal on Del Mar Boulevard
The City of Pasadena has hired Select Electric, Inc., to install new traffic signal equipment and related concrete infrastructure on Del Mar Boulevard at Michigan Avenue. The project starts in June 2025 and is expected to be complete in November 2025.
The plan that governs Caltech construction
This plan, approved by the City of Pasadena, sets forth rules and guidelines for development on campus:
