Structural Revision s
-=-ALBRIGHT ~~&ASSOCIATES
Memorandum
As requested a few structural revisions were desired for the remodel :it the Grangroth Residence.
The following changes to the structure m:1y be made :
-A 2x 10 ledger m;1y be used at the Jeck framing. The 2x I 0 is to be nailed to the wall
framing with 5-16d nails at each stud, with a maximum spacing between rows of 16" o.c.
T he specified joist hangers arc to be nailed to the ledger.
-The conc rete piers supporting the deck columns may be square rather than the round
piers we had previously specified . 4-#5 dowels arc to be hooked from the footing to the
pier, the remaining information found on detail 3 on sheet S3. l remains relevant.
-The b<1semcnt slab may be poured with 3000 psi concrete in place of the 4000 psi concrete
that we had specified . The lesser compressive strength of 3000 psi m;1y cause more
cracking in the slab and the owner must be willing to ;m:ept the potential for :1dditional
visual defects. The welded wire fabric in the slab may also be replaced with #4 re bar at 16"
o.c. each way.
-The stone \'en eer shown in detail 3 on sheet S3. l may be supported by a 3x3 angle in place
of the dry stacked emu. The angle should be fastened to the concrete wall with 1/2"
diameter cxp;msion bolts@ 24" o.c., embed 4" into the concrete. Ensure the ledger and
fasteners arc properly protected to prevent moisture contact .
