A descending grade of 4.2% intersect an ascending grade of 3% at station 11+488 of elevation 20.8m. These two gradelines are connected by a 260m parabolic curve. Where should the location of the drainage pipe from PT be laid. If the outside dimension of the pipe to be installed is 95cm and the top of the pipe culvert is 30cm below the curve what is the invert elevation?
