Ratcliff provided the design for seismic corrections and programmatic improvements to the 129,500 s.f. Bancroft Library (annex to the Doe Memorial Library and the most accessible and heavily used special collections library in the country). Located in the historically sensitive “classical core” area of the UC Berkeley campus, the project presented an opportunity to reevaluate how the Doe and Bancroft Libraries interface with each other, how security and operations within the Bancroft Library could be improved, and how the public perceives and uses the Bancroft Library. The final design included the creation of public exhibit space and increased visibility of the library overall. Because the annex is connected to Doe Memorial Library, planning included measures to allow the adjacent occupied spaces to continue to function, while mitigating any disruptions to on-going functions. Careful coordination with our historic consultant took place to ensure our design met the requirements of the Secretary of the Interior’s State guidelines.
The design team met multiple challenges as well as saving and restoring the original Kawneer aluminum double hung windows. This was done through careful energy modeling that revealed energy goals could be met with only the addition of more insulation to the roof and walls vs. changing out the windows to allow insulated glazing. A UV film was added to the interior side of the glass to satisfy the library needs for UV control, and the sash was inconspicuously secured to the frames with a matching silver sealant to achieve security and air infiltration control – both demanded by the rare books preservation consultant. The new shear walls were inboarded so as not to affect the exterior fenestration. The terracotta skin (innovative cladding that mimicked the Doe Library’s Sierra White granite cladding) was not harmed through our extensive interior gut and full rehabilitation.
