Dear Sundar and Girija:
At your request, I have revised an error that indicated an 18' shear wall when in fact it was a 10'-6" shear
wall. The W1 shear wall schedule remains the same, and the holddown locations and types remain the
same..
Please call with any questions and/or comments you may have.
Sincerely,
��Q(tOFESS/Oq
