What size is the vertical duct located between grid lines 4 and 5?

The correct answer reflects the dimensions of the vertical duct as specified in the relevant section of the construction drawings. When analyzing the print, it is essential to closely examine the duct sizing notation and orientation provided in the details or section views of the plans, particularly the area situated between grid lines 4 and 5.

In this instance, the configuration shows that the duct's wider dimensions are designated to be read as 62" in height and 48" in width. This is consistent with standard practices where the first measurement typically indicates the height of a duct when oriented vertically. Recognizing this ordering is crucial for interpreting larger systems in mechanical, electrical, and plumbing (MEP) design accurately.

Understanding duct orientations and dimensions is vital for ensuring proper installation and airflow, which ultimately contributes to the efficiency and effectiveness of the HVAC system being implemented within the structure.
