NW Seismic Workshop on Retrofitting

Michael Wieber, co-owner of NW Seismic in Portland, Oregon, gives a workshop at the SouthEast Portland Tool Library on Jan. 11, 2014 for the DIY crowd. In his three-hour presentation, which we've condensed, he talks about the importance of fitting the seismic retrofit to the home and not imposing a prescriptive design, which is all too common.
