rubble foundation
have a project where the architect wants to remodel facade of building with 4" blocks.  problem is the foundation wall consists of 3 different materials... stone, brick and concrete block.  in addition the brick slopes at the base approximately 15 degrees.  anybody have any suggestions?  height of the block is approximately 9 feet.
thanks

the existing is battered stone?  and he wants to replace the battered stone into battered brick instead?
no, the stone is currently parged.  he wants to attach a lintel to support the block which will be the new facade over the existing.
use very long thru bolts with epoxy?  be very conservative maybe with the # maybe?  or create a new foundation (hopefully your frost depth isnt very deep) and rest the facade on the new foundation.
thought about the foundation but i would need approximately 4 feet deep and would need to remove existing sidewalk.  the wall would probably be encroaching within the city's right of way which again would be a problem. i was actually thinking about installing hss columns along the inside face and extending hss stubs through the wall and welding my angle; again pretty expensive.
when adding a new facade of a heavy material such as block, normal practice is to remove the existing facade first.  only if you are using a lightweight facade material such as aluminium panels should you consider leaving the existing heavy facade in place.  and the architect should know better.
