Archer Western Contractors, Ltd. Carollo Engineers Contract Mod. No.: CMR 1.' ------------ Carollo Engineers and Archer Western Contractors, Ltd . acknowledge that the work shown in the referenced Contract Mod ification Request 7 (CMR 7) 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 7. 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. CMR 7 includes the cost related to the pipe adapter at RS piping area . During the construction it was found that the existing 24" RS which is called out as CIP is actually 24• RCCP. The RCCP has a bigger OD than Ductile Iron Pipe and will not allow a flexible coupling connection. Contractor will provide an adapter to connect the new 24• DIP and existing 24• RCCP. Contractor's request for change and detailed cost breakdown is attached with this document. 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.
