A high intensity Magnitude 6.3 earthquake caused massive overall damage in Christchurch, New Zealand on February 22, 2011. The National Science Foundation funded a Rapid project entitled Mapping of Damage in Precast Concrete Buildings to gather perishable data on the damage of precast concrete buildings. This report contains an assessment of the damage to a 9- story precast concrete hotel and a 5-story precast concrete parking garage resulting from these earthquakes, as well as background on this earthquake and two others that occurred near Christchurch. To generate this assessment, data was collected during a site visit to each building. Col lected data included photographs of visible damage and acceleration data from earthquake aftershocks and ambient vibrations for both structures. A description of the damage documentation process, resulting crack maps, and processed acceleration data are in cluded in this report. This project was the result of collaboration between the University of California at San Diego; the University of Arizona; the Pacific Earthquake Engineering Research Center at the University of California at Berkeley; the Univers ity of Canterbury, Christchurch, New Zealand; NEES at the University of California Los Angeles; the Precast/Prestressed Concrete Institute and Precast New Zealand. An objective of the project was to mentor and train a postdoctoral researcher ( Dr. Matthew J. Schoettler) and an undergraduate intern (David Deutsch), a PEER REU . Dr Schoettler and Mr Deutsch traveled to New Zealand where they joined a team from the U niversity of Canterbury and a team of structural engineers from the company Powell Fenwick and conducted a survey of the damage of on a 9- story hotel building and on a 5- story parking garage. With the help of NEES-UCLA equipment and personnel, they also acquired ambient vibration and aftershock data.
