FORT WORTH WATER CONTRACT MODIFICATION REQUEST 14 Village Creek Wastewater Treatment Plant Secondary Area Rehabilitation and Modifications City of Fort Worth, Texas Date: November 15, 2011 P275- Secondary Area and Rehabilitation and 70130 Project: Modifications Project No.: 0128980 Recipient: City of Fort Worth Subject: RS 2 and 3 Grating Supports Contractor: Archer Western Contractors, Ltd. Engineer Carollo Engineers Contract Mod. No.: CMR 14 CMR 14 includes the cost of furnishing and installing new support beam and columns for the new FRP grating at RS 2 and 3.The existing grating supports beams and columns will be demolished and disposed by the Contractor. Detailed cost breakdown for the construction work are attached with this document. Carollo Engineers and Archer Western Contractors, Ltd. acknowledge that the work shown in the referenced Contract Modification Request 14 (CMR 14) represents work items not included in the original bid and changes the as-bid price of work items that were included in the original bid. The nature of the change is adequately described in the justification provided with the CMR. The Contractor's contract modification proposal has been reviewed by the Engineer, and the Engineer has certified that there is incremental cost and is reasonable to accept "as-is." The Engineer has therefore recommended to City of Fort Worth to approve the CMR 14. The need for this work was discovered during construction of related work items. Therefore, consideration of procuring this work by any means other than by Contract Modification was neither practical nor desirable. Procurement of this item by Contract Modification to this contract is justified in that the work is directly related to and intermingled with other work, which was included in the original procurement by public bid.
