rubble foundation

[calculor1]

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.
