Building a Ground-Level Deck

Batterboards and mason's string lines were used to lay out footing locations for a deck that is approximately 8 feet wide and 10 feet long. Six holes for 8-inch-diameter footings were dug with a posthole digger. Each hole is 12 inches deep. There is no frost line to deal with since this is a freestanding deck. Tube forms were used to level the footings about 1 inch above ground level.

Approximate time for a novice (with a helper) to lay out footing locations, dig holes and level tube forms for this deck: 5-7 hours.

Six 60-pound bags of ready-mix concrete were mixed in a wheelbarrow. Post anchors for 4x4 posts were attached to the footings after the concrete cured for 48 hours. The anchors were aligned with a long straight board. Diagonal measurements were checked to square the anchor positions.

Approximate time (not including curing time): 3-4 hours.

Beams were made from double 2x6s. They were attached in the post anchors. A 1/2-inch-thick pressure-treated shim was installed between the beam and one side of the anchor at each footing. The anchor is 3 1/2 inches wide and the beam is 3 inches thick.

Approximate time: 2-3 hours.

Beam alignment was checked and adjusted as necessary to make certain beams were square.

Approximate time: 1/2-3/4 hour.

2x6 rim joists were attached to the ends of the beams. Angle brackets were installed to provide additional support for the corner joints.

Approximate time: 1-1 1/2 hours.

Inner 2x6 joists were attached to the beam faces with joist hangers.

Approximate time: 3-5 hours.

Align the inside edge of the first length of decking with the chalk line. Drive two fasteners through the board into the center of each joist. Position each fastener ¾ to 1 inch from the edge of the board.

Approximate time: 3-5 hours.
