Swapping MGS post locations at obstructions

Question
State IA
Description Text
I’d like your opinion on swapping MGS post locations
in order to avoid an underground obstruction.  This situation is shown in
the attached drawing.  Note that post spacing would not exceed 6’-3”.

 

Thanks,

Previously, we have recommended that posts not be placed at a splice location when using the standard post spacing. When moving to a reduced post spacing, we have also suggested that one allow 1 to 2 half-post spacing prior to locating a splice at a post. Based on your figure, a splice is located at a post which is adjacent to a 6-ft 3-in. span. To remedy this scenario, the interior two 12-ft 6-in. long panels could be replaced with a 25-ft 0-in. long panel, as shown in the attached figure. Can you accommodate one larger panel? If not, we could use a 6-ft 3-in. panel to make a shift and then add some extra posts to make it work out.

I think we could accommodate the one larger panel, but I’m also curious about the 6’-3” panel option.  Could you send me a sketch?
