Level and Adjust Main Deck Sub-Frame

What happens here

Using a measuring tape and level, meticulously check and adjust the wooden sub-frame of the main deck. Ensure all joists and beams are level and properly spaced to provide a stable and flat surface for the decking. Make any necessary cuts to the joists using a circular saw to achieve the desired dimensions or to accommodate specific design elements.

Goal: Ensure the main deck's sub-frame is level and structurally sound.
