The subsurface profile at a construction site in Hong Kong is shown below (not to scale). A bored pile with a diameter of 1.5 m and an embedded length of 45 m is to be installed. Estimate the range of the ultimate shaft resistance and of the ultimate base resistance of the pile. Make and state whatever assumptions you consider necessary and reasonable.

Besides, what is the specific name of "DG Fill Loose to medium dense", "Dense CDG" and "C/H DG Dense state"? And how to determine the bulk density of each layer? Are there any reference forms to check the bulk density?
