Riser Orientation Mark Is Missing Before the Section Is Raised
Mark the section orientation from the current drawings and adjacent connections before it enters the shaft. Include floor, system, airflow, top, branch direction, and connector orientation as needed.
This riser piece has no clear up/down or branch-direction mark. I matched the piece number, but it can be rotated two ways. Can we verify and mark the orientation before it is raised?
Watch out
Do not assume a symmetrical-looking riser section can be flipped later.
Check
Match the piece mark to the spool.
Verify branch clocking and offset direction.
Identify which end is up and which floor receives each connection.
Photograph the markings before the section moves.
