A level was setup between BM A and TP1. The upper, middle, and lower cross hair readings on BM A was .718, .633, and .550 meters. The upper, middle, and lower cross hair readings on TP1 was 1.131, 1.051, and .972 meters. The elevation of BM A was 103.8432 meters. Determine the elevation of TP 1. Hint: This is 3 Wire Leveling. It is often utilized when determining the elevation of TBMs for route construction projects since the method allows one to compute the distance from the level to the BS and FS(keeping them balanced), determine an average middle cross hair reading, and increases the precision of the answer.
