**Abstract**

Geophysical investigations for design parameters related to geotechnical engineering consider the application of geophysical methods such as electrical methods, seismic methods, magnetic prospecting method, electromagnetic prospecting methods, and these methods are needed to delineate the subsurface geological features before the erection of building structures, and design parameters used for geotechnical engineering can be investigated using geophysical methods. Moreover, geological structures such as fractures, faults, contacts, dykes, etc. can easily be delineated using geophysical methods, these geological structures are responsible for ground subsidence, building foundation problems, and building failures, which can affect the development of geotechnical engineering, and case studies will be referenced for easy understanding*.*
