New RFI No. 16		
As of 23-Jun-2009 5:05 PM CT	
Vitruvian Infrastructure Phase 1B
4010 Marsh Lane Addison, Texas 75001 
Project Number: 1308B
	

 	Status: Outstanding	  	
Subject	Proposed line SS-B Fix and grade changes  	
Reason Code   	 None 	 
Question	 As a formal response from RFI #7 where Clay Barnett stated the following: "It is apparent that the section of Line SS-B between STA 14+79.68 to 15+63.68 was not placed on 0.30%
slope as indicated on Sheet 68 of the construction documents. Therefore this section of Line SS-B shall be reinstalled at the slope specified in the Construction Documents. Since the
slope of the pipe downstream of STA 14+79.68 is greater than 0.30%, it would be possible to reinstall a section of this line on minimum slope. This would mitigate the need to go upstream
of STA 15+63.68. If North Texas Contracting would like to pursue this option, a new RFI needs to be issued requesting the plan revision. "

 
Proposed Solution	 NTC proposes to re-install line SS-B as shown on the attached sketch. NTC will take the slight PI difference out of the 4 - 14' laying joints. Please advise if this
is acceptable, and provide a plan revision for construction.
