Engineer said no problem. If these are not problems, what are, excluding the obvious seismic crushing of freeway columns? In other words, are cracks in concrete stress relief?>> Your statement is a bit general. Usually, the engineer has been asked to the site in response to an owner's concern as to whether his building is safe for occupancy. Therefore, when reviewing the cracks in concrete, the engineer looking at the damage usually is answering a very specific question, which is: "Does the crack indicate a hazardous condition?" The answer to that question is usually "No problem". It does not mean that the crack is acceptable from an architectural viewpoint, or that the crack does not need to be repaired or the building upgraded. It's just the engineer answering a very specific concern. Carl S. ...
