Eric, I know the answer to #3. Could you look at the other two? Thanks, Clay Barnett, P.E. Town Engineer Town of Addison 16801 Westgrove Drive Addison, TX 75001-2818 Office: (972) 450-2857 From: Gomez, Rafael [mailto:rafael.gomez@dsiamerica.com] Sent: Thursday, May 20, 2010 9:49 AM To: Clay Barnett Subject: FW: Addendum- Vitruvian park Mr. Barnett: After checking the drawings I have some questions: 1. Are these hanger roads to be post tensioned ?; are there any specs for these rods ? 2. They call for 2” bars which we do not have. We either have our #18 GR75 bars or the high strength 2.5” GR150 bars. Will any of these be acceptable ?. 3. will all thread bars be accepted ? thanks Rafael Gomez Sales Engineer, Post-tensioning & Reinforcing Business Unit DYWIDAG-Systems International USA Inc. 2400 N.
