Bracing Details: The author installs diagonal braces at the column-beam connections on freestanding decks to prevent the structure from racking side-to-side parallel to the house or laterally away from the house.

Instead of concrete tube forms, the author uses helical screw piers from TechnoMetal Post.
The screw piers can be installed with a small gas-powered machine and barely disturb the landscape.
