Contract Mod . No.: CMR 1 Change Order No.: 1 -------------------
Carollo Engineers and Archer Western Contractors, Ltd. acknowledge that the work shown in the referenced
Contract Modification Request 1 (CMR 1) 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 w ith the CMR.
The Contractor's change proposal has been reviewed by the Engineer, and the Engineer has certified that
there is no incremental cost and is reasonable to accept "as-is." The Engineer has therefore recommended to
City of Fort Worth to approve the CMR 1.
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 Change Order to the Contract already under construction to
do the related work was neither practical nor desirable.
The Contractor has proposed 30 " flanged butterfly valves in lieu of 30" grooved butterfly valves shown on
Contract Documents. A grooved coupling is also provided by each valve for future disassembly. Contracts
request for change and detailed drawing of new piping configuration are attached with this document.
Procurement of this item by Change Order 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 .

Clarifier fittings and Adaptor CMR No.: 2 -------
Carollo Engineers and Archer Western Contractors, Ltd. acknowledge that the work shown in the referenced
Contract Modification Request 2 (CMR 2) 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 2. The increased cost breakdown is attached with
this CMR.
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 .
The Contractor has proposed 30" flanged butterfly valves in lieu of 30 " grooved butterfly valves shown on
Contract Documents. A grooved coupling is also provided by each valve for future disassembly. Contractor
request for change and detailed drawing of new piping configuration are attached with this document.
During the construction it was found that the existing 36" ML which is called out as CIP is actually 36" RCCP.
The RCCP has a bigger OD than Ductile Iron Pipe and will not allow a flexible coupling connection as shown
on the drawings. Contractor will provide an adapter to connect the new 36" DIP and existing 36" RCCP. The
adaptor detail is attached with this CMR. Also, 12" Drain line is shown to have a 45 bend going to the sump
box. After excavation, contractor found the existing pipe to be a straight run without a 45. The existing sump
box was built to where a 45 was not required. Contractor will provide a cost to supply/install the 45 degree
bend .
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 orig inal procurement by public bid.
