Response to RFI No. 20 As of 10-Jul-2009 1:30 PM CT Vitruvian Infrastructure Phase 1B 4010 Marsh Lane Addison, Texas 75001 Project Number: 1308B Status: Complete Subject Plan grade bust on storm line SD-A1 Reason Code None Question On revised sheet 33 for line SD-A1, the profiles show a proposed 2.00% slope between stations 2+94.35 and 3+31.05. When proposed flowlines are calculated, this slope is actually around 1.66% (at 36.7 LF). Proposed Solution Joel, per our conversation, NTC is to correct this bust by running at a 2.00% from 2+94.35 to 3+31.05, and modify the 5'x5' RCB flowline elevation up at station 3+31.05. NTC will note the flowline elevation change at station 3+31.05 on our as-built drawings and documents. Attached Files (none) Section: 2 - Sitework Int.
