1. Draw a sketch of the pool shape on the grid provided in the measuring sheet.

2. To represent the A - B line, mark 2 points on the deck about 3 feet away from the pool. Note that your A is always on the left of B as you face the pool and the pool is in front of your A - B line. This A - B distance should be about 2/3 rd's of the total length of the pool. Make sure that the A - B line does not cross the pool.

3. Measure the A - B length and enter it in the A - B space provided on the sheet.

4. Use chalk to mark points clockwise around the entire edge (inside) of the pool at about 3 feet intervals. The first point should be directly across from the center of the A - B line. All the corners including the step should be marked and the inside curves should be marked at 1 foot intervals.

5. Any obstructions, like slides, legs, ladders, rock waterfalls (all non removable obstructions) within 18 inches away from the water edge should be marked. This could be done last.

6. Using a measuring tape, measure the distance from point A on the A - B line to all the points on the pool starting from #1 and record it in the A column of the A - B sheet. Likewise, measure the distance from B to all points on the pool to record it.
