Uber Advanced Technology Group is a self-driving technologies engineering team whose R&D Center is housed within historic Pier 70. Its four massive buildings, constructed between 1885 and 1937 for ship repair, now extends the site’s legacy of transportation endeavors into the 21stC. The challenges of upgrading physically deteriorating and seismically deficient historic landmark edifices for a modern company, are both technical and architectural. The insertion of mezzanines, bridges and stairs preserves the historic perimeter brick walls and was integral to the seismic upgrading strategy.
