RE: Collins Deck (1 of 3-Ply Beam Splice Remedy) � �� � � '� �
16848 Enchanted Court
Lakeville, MN 55044
Dear Mr.Schlafman (Paul),
As per your request, I investigated the beam splice of the inboard-ply-only of(3) 2x12s constituting the header at the
deck-only area of the addition ("deck-only" is used to deconflict with the three-season porch).
I found the following:
• 10' header span
• 16'joist system span
I conclude 10d nails @ 10" oc at the top and bottom connecting each ply to the other respectively and a 4"x 6"
minimum mending plate at the splice of the inboard ply will suffice structurally.

Sincerely,
