I am working on a project that already had the topography and house built the way the designer wants them, yet we are struggling with some discrepancies in elevation heights shown in section/elevation vs. the elevation points on the physical topography in the site plan. I attached images below of the different elevations. Any help is greatly appreciated!Click image for larger version.
