Library Retrofit Moving Into Seismic Strengthening Phase in June

The Central Library retrofit project is closing in on a major milestone. The first concrete pour, expected in June, will mark the beginning of structural and seismic improvements as the long-anticipated renovation moves deeper into full construction.

Library Director Tim McDonald said the Central Library Seismic Retrofit and Renovations Project is now in Phase 2, following the completion of selective demolition and preconstruction work. The project remains on track for substantial completion in 2028.

“Beginning in May, work in the basement will expand to include earth-moving removal of excess soil to make room for new, upgraded foundation elements,” according to the City Manager’s Newsletter. “This preparation work will set the stage for the first concrete pour, expected in June, marking the beginning of the major structural and seismic strengthening work.”

Earlier phases focused on preserving the building’s historic features while preparing it for modernization. Crews carefully removed and stored wood finishes, abated hazardous materials and dismantled aging heating, ventilation and air conditioning, plumbing and other systems. The contractor, PCL Construction Services Inc., also completed exploratory demolition, installed protective materials to safeguard elements such as cork flooring, secured permits and delivered a guaranteed maximum price for the project.

Full construction began in March after the City Council approved an amended contract. An 18-person crew is currently working in the lower basement levels, removing slab-on-grade concrete to prepare for upcoming structural pours.

Beginning in May, crews will expand work to include excavation and removal of excess soil to accommodate new foundation elements — a step that will set the stage for the first major concrete placement.

At the same time, workers are protecting portions of the building that will remain in place, including windows and cast stone, to prevent damage during construction. Preparations are also underway to safeguard nearby trees ahead of roof tile removal and the installation of scaffolding around the building.

Officials said demolition work has progressed without unexpected issues as the project advances toward its next phase.
