Development reduction AASHTO 8.25.3.1

[BridgeBuilderPlus]

AASHTO 8.25.3.1 says:
Reinforcement being developed in the length under consideration is spaced laterally at least 6 inches on center with at least 3 inches clear cover measured in the direction of spacing.....0.8.


What does "with at least 3 inches clear cover measured in the direction of spacing" mean?

I think it means the following ...

Draw a line thru the bars at the indicated spacing. Follow that line to the outside edge of the concrete and measure the distance.

For example, if reinforcing a beam, the clear cover to the side of the beam from the last main bar in that row.
