Seismic report issued on Berkeley Town House

Two seismic engineers reported the findings of an evaluation of senior cooperative Berkeley Town House in June.

Two seismic engineers delivered a report on 15 June 2015 describing the findings of a brief seismic evaluation of Berkeley Town House, a 9-story, 60-unit 1960s cooperative apartment building occupied by seniors in Berkeley, California.

The 11-page report, by Joe Maffei and Karl Telleen of Maffei Structural Engineering, begins with a two-page executive summary. The report lists prior documents that were reviewed by the engineers as part of their evaluation:

  1. 17 pages of structural drawings, 1960
  2. 1962 interview with engineer (page 5)
  3. 1990 engineer letter

  12. 8 pages of mechanical and plumbing drawings, 1960
  13. 9 pages of electrical drawings, 1960

The report discusses five potential risks from a major earthquake, possible additional investigation, and possible remedial measures that might ameliorate risks if confirmed.
