(Plr,�se note that itcm�1 of the September 7 letter incorrcctly <br /> allows 4 plies of 11 7/8"LVL. That should have read 4 plies of 18"LVL.) <br /> From our discussions, you have indicated you would like to add 2 plies of 18"LVL to die <br /> existin�3-ply�LVL t�esm. I have evaluatod the beam nnd determined that thc addition of 2 plies <br /> of 1,VI will bc adeqvate under the following conditions: <br /> • F,r•aluate the structure(especially the existing 3-ply LVL)for any defects. <br /> • Jack up the header slightly to remove some of the deflection if possible. <br /> • Ensure that the 3 plies aze currently pmperly fastened wgether—add nails to the inside ply if <br /> required to provide 3 rows of 16d common nails at 12"on center in each row. <br /> • Install2 plies of 18"LVL(one ply at a time)nailing each ply with 3 rows of 16d common <br /> n�ils at 12"on center in each row. Note"en9ure contact at the top,with framing above(shim <br /> i f nccessary);trim 2x6 plate as required for flush installation. <br /> • E3ott all 5 plies using 3 rows of'/�"bolts(with washers)at 12"on centor in each raw. <br /> • Provide support for the ends of the LVL,to the foundation below. <br /> Note that the columns at the ends of the 5-ply beam must support as much as 25,000 lbs. The <br /> foundation and footings must be capable of supporting those loads. <br /> � �� � - . <br /> �- -�- ....� � �. . <br />
