Town Engineer Town of Addison 16801 Westgrove Drive Addison, TX 75001-2818 Office: (972) 450-2857 From: Hernandez, Cesar [mailto:chernandez@craigoldeninc.com] Sent: Friday, May 21, 2010 2:48 PM To: Clay Barnett Subject: Reference: Vitruvian Park ADDENDUM#2 Clay, We intend to submit a bid for the temp shoring on the VITRUVIAN PUBLIC INFRASTRUCTURE-PHASE 1D project. I calculated the square footage and came up with different quantities than yours. Could you please have your structural engineer verify quantities. Temporary Special Shoring Your #’s: Ponte Ave. – 1,325 SF Bella Lane -1,780 SF My #’s: Ponte Ave. – 1,378 SF Bella Lane -2,500 SF Please let me know if you have any questions. Thanks! When we rechecked our calculations, we determined a new value of 1,378 SF for Ponte Avenue was appropriate and the original value of 1,780 SF for Bella Lane was correct. Keep in mind the temporary special shoring at the ends of the Bella Lane approach slabs will not extend the full 10' depth. We're assuming a conservative depth of 5' at each end of the bridge. The Ponte Avenue quantity has been revised on the Base Bid as well as on Sheet S1-04.
