“SOFT STORY” RETROFITTING
Winnetka Retrofit, Los Angeles
JDC was retained for this retrofit in Winnetka, CA for the seismic retrofitting that needed to be completed on the soft story parking and to repair the existing settling and sagging that had occurred of the years.
SCOPE OF PROJECT
Retrofitting of the soft story parking and replacing the existing foundation. The seismic work consisted of the shoring up the soft story parking, jacking up the prior settlement of the buildings due to settling of the existing foundations, doubling up existing floor joist with new trusses, adding new sheer paneling and hold downs, adding new grade beams and footing.
The major challenges were in the shoring and jacking up of the existing building due to the major settlement that had occurred over the years in addition to replacing the existing parking lot to achieve the proper drainage. There was a considerable amount of coordination that had to take place between our staff and ownership due to the fact that the building was occupied at the time of the repairs.
