A highway centerline subgrade elevation is 635.22 ft at station 12+00 and 630.98ft at 17+00 with a smooth grade in between. To set blue tops for this portion of the centerline, a level is setup in the area and a plus sight of 6.19ft taken on a benchmark whose elevation is 632.08ft. From that HI, what rod readings will be necessary to set the blue tops for the full station 12+00 and 17+00?
