Scaffolding Installed in Central Library Courtyard as Seismic Retrofit Advances

Construction crews have installed scaffolding inside Pasadena’s historic Central Library courtyard as work continues on the building’s earthquake retrofit and renovation project.

The latest phase follows the removal of roof tiles from the portico roofline surrounding the courtyard, giving crews access to some of the highest sections of the roof.

“Safety remains a top priority in all aspects of the project. Crews continue to follow all established safety protocols. Access routes are clearly marked, work zones are controlled, fall protection systems are in place and regular safety inspections are conducted. Keeping access to all active work zones clear and easy to navigate helps ensure the process remains timely and safe,” according to a statement in the City Manager’s Newsletter.

The library has been closed since May 3, 2021 after engineers determined the unreinforced masonry structure did not meet modern earthquake safety standards, the library is undergoing a comprehensive seismic retrofit and restoration intended to preserve one of the city’s architectural treasures for future generations.

The project is expected to be completed in 2028.

Workers used a specialized method to erect the interior scaffolding in order to protect the building’s historic architectural features. Instead of anchoring the structure to the library’s exterior walls — a process that could have damaged the intricate carvings along the façade — crews secured the scaffolding at the base to the portico roofline and at the top to the higher roofline.

The approach provides a stable work platform while preserving the building’s decorative stonework.

Designed by renowned Southern California architect Myron Hunt and completed in 1927, Pasadena’s Central Library is one of the city’s most significant civic landmarks. The Mediterranean Revival building anchors the historic Civic Center District, a National Historic Landmark District recognized as one of the nation’s finest examples of City Beautiful planning.

The newly installed courtyard scaffolding complements the extensive scaffolding already surrounding the outside of the library, giving construction crews improved access to elevated work areas and creating a safer environment for ongoing restoration and seismic upgrades.

City officials said safety remains a top priority throughout the project. Crews continue to follow established job-site safety protocols, including clearly marked access routes, controlled work zones, fall protection systems and routine safety inspections.

Maintaining unobstructed access to active construction areas helps keep the project on schedule while reducing risks to workers, according to the city.

Recent work has included demolition and foundation improvements in the basement, where crews have been pouring new concrete footings as part of the seismic strengthening effort.
