excavating under existing comm.building
(OP)
An existing tenanted rc frame building is in dire need of on site parking. Does anyone know of possible techniques to undermine the building for three levels of parking. The concrete columns are at approx. 7m spacings and the plan area is about 3000 m^2. Cape Town SA.

The bigger problem may not be supporting the existing footings as much as supporting the lowest existing floor slab which is probably a thin slab on grade. A similar project, I think, is being constructed at the United States Capitol Building in Washington, DC.
