I was wondering what everyone's standard of practice was in reference to verifying the integrity of existing footings. If you are to design a building on existing footings, is it always necessary to "investigate" the existing? How is the reinforcing and the strength of concrete verified? If I'm enclosing my patio and using engineered design, do I need to have a special inspector or the like check my existing footing? My question is due to a building department's requirement for me to core drill, test, and x-ray the existing footings of a building. I have inspected the footings visually for size and checked some footings for rebar size and feel that this is adequate. Normally for this type of work, I haven't heard of anyone "checking" the existing footings unless the loading is higher than before. In this case the footings have been there for several decades and the old building is masonry as opposed to wood and stucco now. What would you think is reasonable for me to do at this point?
