2. Deck Layout

Layout of a deck is done by transferring the scale deck design onto the ground at the jobsite. Using 10” spikes push one spike into the ground at each corner of the deck. Join the spikes with string to show the perimeter of the deck.

You could also spray paint the deck outline on the ground.

Layout and Footing Locations

Footing locations are laid out within the perimeter of the deck showing the center line of the hole to be augured.

When laying out the footings, remember:

  1. Maximum joist span of a 2X8 is 10’ – 6” at 16” o.c.
  2. Maximum cantilever of a 2X8 is 24” at 16” o.c.
  3. Maximum cantilever of a double 2X8 beam past a support post is 12”
  4. Maximum span between footings is 6’
  5. Standard size Sonotube is 8” but check the building code as it varies between areas.

Transfer the deck dimensions from the drawings to the ground.
