Install Main Beams (Girders)

What happens here

Carry the long, heavy wooden beams, which appear to be 'ProWood TrueFrame' joists (used here as girders/beams), to the installed piers. Carefully position each beam onto the post base brackets. Use an impact driver (a DeWalt model is visible on the deck later) to secure the beams to the brackets with structural screws. Continuously check the level of the installed beams using a long level to ensure the deck foundation is perfectly horizontal. Multiple workers are shown collaborating to lift and position the beams due to their length and weight.

Goal: Create the primary horizontal support structure for the deck.
