A soft story building is a multi-story building in which one or more floors have windows, wide doors, large unobstructed commercial spaces, or other openings in places where a shear wall would normally be required for stability as a matter of earthquake engineering design.
The un-reinforced masonry buildings (UMB/URM) have several deficiencies relative to its ability to resisting a major earthquake activities. The California state bill addressed all UMB/URM buildings which were built prior to 1933 to be seismically upgraded for the public safety.
Non-ductile concrete buildings are structures that contain brittle concrete elements (columns, beams, walls, and connections) that tend to perform poorly during earthquakes due to the limited amount of provided reinforcing steel.
Retaining walls are relatively rigid walls used for supporting soil laterally so that it can be retained at different levels on the two sides. Retaining walls are structures designed to restrain soil to a slope that it would not naturally keep to (typically a steep, near-vertical or vertical slope).
Any changes or alterations that include painting, installing partitions, changing the flooring, or putting in customized light fixtures will consider as commercial Tenant Improvement (T.I. Work).
