Preservation is Overtaking Us brings together two lectures given by Rem Koolhaas at Columbia University’s Graduate School of Architecture, Planning, and Preservation, along with a response by Jorge Otero-Pailos. In the first essay Koolhaas describes alternative strategies for preserving Beijing, China. The second talk marks the inaugural Paul Spencer Byard lecture, named in celebration of the longtime professor of Historic Preservation at GSAPP. These two lectures trace key moments of Koolhaas’ thinking on preservation, including his practice’s entry into China and the commission to redevelop the State Hermitage Museum in St. Petersburg, Russia. In a format well known to Koolhaas’ readers, Otero-Pailos reworks the lectures into a retroactive manifesto, using it to interrogate OMA’s work from within the discipline of preservation.
