Check the as-built stake-out error for one of the main diagonals of the property and location of one of the column supports. Property dimensions 20’x 18’. Equipment: Leica 307 Total Station (UK#A624074) Tripod Prism rod Hubs Stakes Mallet Weather: 66 ° F 30.21 in 47% Relative Humidity Procedure:

Now send the rod holder in the direction of where point 2 will be. This should be directly horizontal at a 0 ° angle. The rod holder should be 18 feet away. Take a shot and see how the distance relates to that figure. Adjust if needed and then place another stake at that point. Take another shot and record this data as the as-built stake. 5. Now using the Pythagorean Theorem, find the angle that must be turned and the distance to the other corner diagonal from point 1. 6. Repeat step 4 using the angle and distance found in step 5 to locate the stake at point three. Once the stake is set. Take a shot and record as the as-built stake. 7. For the fourth corner of the property, a 90 ° angle should be turned and...
