Dig diagrams or dig plans are construction plans typically provided by the manufacturer of fiberglass or vinyl-lined in-ground or semi-in-ground pool.
These plans offer detailed instructions for the dimensions and depth that the contractor must dig the pool for a proper installation.
Most dig diagrams are highly detailed, providing all of the specifications and markings for where different pool components will be located when the installation is complete
. These diagrams also highlight the location and dimensions for connected features, like a spa, bubblers, or jets.
