An automatic lasers eliminates a lot of that work, and then there are semi-automatic slope lasers that automatically adjust some of the functions. 2 How do you use a transit level for an above ground pool? STEP 1: Identify 2 fixed points and triangulate them to find the center point every other point can be measured from. While much of surveying has been computerized with assistance from global positioning systems there is still a use for the transit in determining grade or slope where all points can be seen. There are three distinct types of Grade Rods: Engineer's Rod; Builder's/Architect's Rod To better understand the work required, we divided the project into 3 sections.

It means use a surveyors transit tool to get an accurate level of the ground so that the water can follow better. Place the instrument atop the tripod and secure the center attaching screw. For example, if the reference point showed a measurement of 46 inches off the ground and the measurement at the second point showed 40 inches off the ground the ground level at the second point would be 6 inches higher than the reference point. East is 90, south is 180, west 270. Press the feet of the base firmly into the ground. Have your helper take a fence post and walk out to the approx.

Check the level on the transit every few measurements. If it gets nudged you have to start at the beginning so make sure its safe and secure. Adjust the legs until the spirit level, a small vial of liquid containing a bubble, shows it as level, with the bubble centered between the lines. If you get it close to level, a pendulum or small motor system fine-tunes it to near perfection, usually within 1/16-inch per 100 feet.
