We do these types of retrofit to the old foundations.
For example ,if we want to add another floor on top of an existing.
Please be more specific about the column and footing sizes and the loads also
What is the stage of the construction at the moment.
(By the way 300 kN/m^2 , which is more than 6000 psf is very dense soil)
Main design criteria here is to transfer shear and flexural forces ar intersection surfaces of old and new concrete.
Using epoxy bonding agent (like SIKA products, to bond old concrete to fresh concrete ) would make the design work better.
