JAM Concept Remodeling established itself as a leading design-build contractor in providing evaluation, engineering, and construction services for seismic retrofitting of soft-story apartment buildings. We have retrofitted many soft-story buildings (construction completed and signed off by the City). We are currently providing soft-story seismic retrofit plans and construction on several multi-story apartment and condominium buildings located throughout the Portland Metro Area. These seismic safety improvements are intended to comply with the City’s codes. Soft, weak, or open-front wall buildings, referred to as “Soft story buildings” are seismically vulnerable wood-framed multi-unit multi-story apartments or condominiums that have tuck-under garage parking provisions and openings at the first (ground) level walls.
6. Contact our company if you wish to comply or need assistance with the retrofit of your building. Cost-effective soft story seismic retrofit engineering design and construction strengthening measures are implemented by JAM Concept Remodeling which significantly improves the earthquake resistance of the buildings without a loss of use of the parking space or the compromise of the building aesthetics. After the retrofit, the property is removed from the city’s inventory list of soft-story hazardous buildings. Please refer to the Projects Completed section of our website for a partial list of recent soft-story seismic retrofit projects completed to date. Our company provides soft story screening and evaluation, soft story seismic retrofit engineering design, or soft story engineering and construction (design/build).
