OVAL POOLS
As any oval or freeform shape fits within a rectangle, it may be easier
to set the location of the pool if the rectangle is laid out first as
described in the previous pages. Choose a fixed point, away from the
over dig (typically the house), from which the first corner stake will
be located. Measure and mark the distance from the fixed point to
the location of the first corner stake. Square the first corner to your
fixed point. The remaining corner stakes can now be set and squared
accordingly as described on page 11.
Once you have your rectangle with a 2' over dig
mapped out, start by finding your center line
stake points. Start at either short side of your
pool (Line 1 or 3 from Figure A on pg. 10), from
the center of that line, measure inside your box the distance of your over
dig plus the distance of your radius (the over dig is traditionally 2' and the
radius can be found on your dig spec) For this example our radius is 9'. So,
measuring inward the 2' over dig plus our 9' radius, results in marking the
ground at 11' in from your rectangle.
From that mark, go over perpendicularly to the side of your rectangle (Line
4 or 2 from Figure A) and measure inward another 11'. Drive a rebar stake
in the ground where these two points intersect to indicate your first
center point as shown.
You can either repeat this process on the opposite side of your pool, in
which case once you have your two center points staked and the
distance between them should equal the center line distance shown on
your dig spec. In this example, that would be 17' 8 ¾".
Another way to find your second center point is the swing method. Tie
string or attach your tape measurer to your first center point and
measure out the center line distance found on your dig spec. In this
example, that would be 17' 8 ¾". Keeping the string or measurer tight,
use spray paint while you swing your 17' 8 ¾" radius arc. Do the same
for your over dig plus radius (here 11'). Where these two points
intersect should mark your second center point. Square both center
points to your fixed point before moving forward.
