Coordination between Basement Shoring and Basement Concrete Wall

[davab]

I have a project where the property line is very tight and the owner wants to capture the basement square footage as much as possible. This basement is locked by the soil in all four sides with one side having a ramp as a parking garage. Depending on the temporary shoring required and thickness of the retaining wall (which will be restrained at the ground level), the client would lose the square footage in the parking garage.

Does anyone have any experience in integrating the shoring with the concrete basement wall to save as much space as possible?

I think the soldier pile and wood lagging, or sheet piling could be considered. Soil nailing is a good choice if no problem in tie into neighboring properties.
