- 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.
