ARTHUR UTILITY OPERATIONS-ADH. To: Mr. Dan Shepherd Front: Joe M. Wilson, Jr., E.I.T. CC~ Project File Date: June 16, 2003 Entail: Fa~ 983-8254 Re:. Explanation of Items, Change Order No. 1 Job.' 01-CPA-231 Mr. Shepherd, The following is a bdef explanation of the Items included in Change Order No. 1. Please review and if you have any questions or require further information please contact me at my office. ITEM NO: 1. Additional cost to provide tie of 8' PVC to ~xistJng 12" water line (project line No. 2g). This item is to provide an additional tie in of the new 8" water line (project line No. 29) to the existing 12" water line at 5th Ave. This is an additional tie in that was not included in the edginal project bid. Installation of this tie in will help provide better flow distribution for the new lines being installed. Additional cost to install 200 L.F. lO" PVC (project line No.46). This item is to install an additional 200 L.F. of 10" C-900 PVC that is to be supplied by the City. This change is necessary due to unexpected field conditions that require moving the tie in point of the new 10" water line approximately 200'. This additional water line footage will relocate the tie in point to a segment of the existing 10" water line, which has not been bypassed and provide a better installation. Additional cost to install ii" water line to alternate alignment (project line No, 33). This item is for the changing of the alignment of the proposed 8" C-900 PVC water line. q~is change is required in order to avoid placing the new water line under an existing structure, The change in alignment will relocate the water line approximately 10' and require the demolition of a existing garage as well as removal of several large bees. This change of alignment will provide an easier to maintain water line and allow the installation to proceed without placing the water line under any structures. Additional cost to install 8" water line to alternate alignment (project line No. 34). This item is to change the alignment and materials for installation of the new 8" water line. This change is required due to the necessity of having to install the new 8" waterline under an existing garage structure by boring. This will also change the materials and methods used for the construction of the portion of the water line under the structure. The C-900 PVC pipe called for in the original bid will be replaced with 8" High Density Poly Ethylene (HDPE). This type of pipe will provide an installation with no joints or seems thus eliminating the chance of leaking from a joint in the pipe. The line will be installed by boring and the annular space around the HDPE pipe will be grouted to minimize the chances of settlement if any. Using this method there will be no need to demolish the existing structure to install the new water line but it will require the replacing of a concrete driveway that will need to be removed for the construction. · Page 2 EXHIBIT B ARCENEAUX & GATES DATE: June 16, 2003 JOB NO.
