  • Joists 2x8 at 16 in o.c.; longest span 10 ft 6 in (allowable 12 ft 6 in, IRC R507.6 for #2 DF/HF/SPF), 1 ft 6 in cantilever past the outer beam.
  • 1 beam line plus the ledger; beam sizes are rule-of-thumb from the depth each carries. Check them against IRC R507.5 or DCA 6.
  • Footings 12 in diameter, 36 in deep; your jurisdiction sets frost depth.
  • Quantities include 10% waste on lumber and decking. Fasteners for connectors are not itemized.

Quantities include typical waste. A starting point: the builder confirms everything on site, and prices are theirs.
