From our field observations, the suction piping appears to be out for alignment by as much as 1-inch in the vertical direction. You have indicated you believe this is primarily due to the existing suction header flange being "out of level". We understand your approach to correct this condition is to re-adjust the upper flange on the new 90-degree bend in order to bring the suction piping together at the coupling. Based on our observations, we believe that in addition to the existing flange possibly being out of level, that the new 90-degree bend is either too tall, not square, or both. Therefore, on behalf of the City of Coppell, you are hereby directed to remove the 90-degree bend and make the necessary corrections and adjustment to the lower flange of the bend. This will require careful coordination with the City of Coppell for the shut down of the pump station and will most likely require the re-installation of the 30-inch blind flange while the adjustments are being made. As we have indicated previously, the City will not be able to shut the pump station down for extended periods of time nor during times of peak demand use. In response to your request for compensation in the amount of $840 for the above described work, it is the contractors responsibility to field measure and verify all pipe fitting work prior to fabrication and installation of the project piping. This includes verifying the condition, orientation and location of the existing pipes and fittings. Therefore no additional compensation will be provided for the work necessary to correct the piping alignment. j :\clc~cal\coppcll\ 1999 - 153 \1 cttcrs\constXk~a] igmcnt corrccti on, doc Architectural Utilities, Inc., dba AUI General Contractors City of Coppell - Village Parkway Pump Station April 6, 2000 Page Number 2 Finally, as we requested, you have provided your proposal for the installation of a ~ -inch tap on the existing 36-inch discharge pipe in the meter vault.
