Planning & EstimatingQuestion 298 of 360
A plan note reads "See detail 3/P-4." What does this callout tell the installer?
a.To pour 3 inches of concrete
b.That there are 4 pipes at this location
c.To look at detail number 3 on sheet P-4 for an enlarged view of that connection
d.That the pipe is 34 inches long
Explanation
A callout like "3/P-4" points to detail number 3 on drawing sheet P-4, where a larger-scale view shows the connection specifics. Following detail references prevents guessing at how a joint or assembly is built. Cross-referencing details is a normal part of reading a full plan set.
