Challenges of upgrading physically deteriorating and seismically deficient historic landmark edifices for modern use, are both technical and architectural. The building conditions were beyond decrepit, and the danger of earthquake-triggered collapse was so dire that the construction site included “safe areas” for workers to take emergency shelter at first tremor. It is to be expected that a 19thC building in San Francisco is not designed for earthquakes. However, the Pier-70 buildings’ vulnerability was exacerbated by years of vacancy during which vandalism, stripping of materials and artifacts, and weather intrusion occurred. An egregious example: water exposed masonry at Building-113 was deteriorated to the point of crumbling to powder. Elsewhere were areas where bricks needed to be replaced, and throughout, the brick needed to be re-pointed. Windows and skylights were in some cases repairable, and in other cases too deteriorated to fix. Replacement materials were meticulously specified to meet current code requirements and historic compatibility. The insertion of mezzanines, bridges and stairs preserves the historic perimeter brick walls and was integral to the seismic upgrading strategy.
A major challenge in high seismic zones is the structural deficiency of old buildings, especially at unreinforced masonry. The new retrofit system is designed to resist a 500-year-recurrence seismic event; steel columns and braces are strategically located along the existing building structure to minimize visual impact. New concrete mezzanines not only add leasable area, but also brace the historic brick walls at mid-height. Full height walls have upper portions sheathed in clear, multi wall poly-carbonate to maintain the building’s original site lines. Demising large industrial spaces with steel and glass walls preserve the spatial character of the cavernous industrial buildings for the client and its neighbors. Conference rooms and other programmed functions are free-standing elements within the large volumes. Lab, shop and kitchen spaces are located under mezzanines, allowing for sound isolation, temperature control and dust containment. The approach retains and repairs salvageable elements. If unsalvageable, the replacement element or material is specified to be historically compatible and environmentally benign. In addition, the conservation and environmental strategies include: maximize day-lighting through sky-lighting and windows, enhance natural ventilation; provide radiant heating; specify permeable concrete at exterior paving.
