(c) Draw a topographic profile from borehole A to C using a vertical exaggeration of 200:1. Please be sure to label your scales. ABC (d) Based on the borehole information where would be the best spot to build a 150 x 150 foot concrete pad for a building foundation? Explain your answer in terms of the overall soil characteristics, topography and soil plasticity. (e) Show where you would put the 150 x 150 foot building pad on the map. Indicate where you would have to cut or fill to make a level pad.
