Installing and Aligning Primary Joists

What happens here

The pre-cut joists are carefully lifted and positioned into their designated places, typically resting on a ledger board attached to the house (implied) or main support beams. As each joist is set, its top edge is aligned with the projected line from the laser level, which is clearly visible across the entire span of the framing. Workers make subtle adjustments, potentially using shims or tapping the joist into place, to ensure it is perfectly flush with the laser line. This guarantees that the entire surface of the deck will be consistently level and free of undulations. The joists are then securely fastened in place using appropriate connectors and fasteners, maintaining the precise alignment. This step is repeated for all primary joists of the deck structure, ensuring consistent levelness across the entire surface.

Goal: Workers meticulously place and secure the main joists onto supporting structures, constantly using the laser level to achieve perfect horizontal alignment and proper spacing.
