write in to your developer,request for a set of structure and mne drawing inform them you wish to begin renovations,and usually their civil engineering engineer would have informed the developer which walls are hackable

Cutting and hacking non load bearing walls are fine,the issues are the wire and pipe run,get your contractor to scotch tape the wires and pipes running between the walls as location mark for future reference

Ideally get an digital ifc file for future references and changes and easy to store
