WATER DEPARTMENT NO. P265-606140036683
Dear Mr. Conlon:
Dunaway Associates, L.P. is pleased to present this Amendment No. 1 for additional water
line engineering design services that are beyond our original scope of services.
• 660 LF of additional 12-inch water line design in order to provide a better looped
distribution system.
o additional design
o additional survey
• 200 LF of additional 8-inch water line design in order to provide a better looped
distribution system.
o additional design
• Detailed traffic control and signage plans preparation as a result of the City preferred
alignment along the street. This task also includes additional survey being taken along W.
Cleburne Rd for the temporary widening of the pavement associated with the traffic
control plans. This task also includes review and coordination meetings with the Traffic
Department in addition to the Transportation and Public Works Department.
• Design of detailed construction sequencing plans. This task includes additional plan
research and preparation of plan sheets outlining the order of construction of the water
line to minimize water down time to the City's customers. This task also included multiple
coordination meetings with the Water Department, Engineering and Field Operations
staff.

• Amendment No. 1

• Additional design for 36" cut-in gate valve at the Hulen St/McPherson St. This task
included full topographic survey of this intersection including an additional 300 feet along
McPherson, in addition to extra control due to the proximity of the proposed gate valve
location in relation to the rest of the project. Shop drawing research, gate valve
placement, and initial traffic control planning was started on this task but not completed
per City's request. The deliverables for this task will be the survey work that was
performed, in addition to the shop drawing research. The design and construction of this
36"cut-in gate valve will be performed and included in a future City project.
• Additional design for 210 LF of 16" ring connection at the McPherson StNV.Clebume Rd
intersection. This task includes multiple layout options to configure multiple fittings for
horizontal and vertical alignments within the intersection and many various existing
underground utilities (existing water line connection points, existing storm drain, existing
gravity sewer, existing force main sewer,fiber optic, gas, &overhead lines). This task will
also involve the preparation of an additional plan and profile sheet for this 16" ring
connection.
• Revision to construction sequencing drawings and preparation of the multiple additional
construction sequencing steps and associated drawings as a result of the 16" ring
connection in order to reduce the shut down time of the single Bethesda Water Supply
Company , City of Burleson and City of Crowley water line feed. Additionally, as a result
of the proposed ring connection and the subsequent down time to the City's customers,
additional plan research was performed to determine the best location to provide a
temporary supplemental water line feed from the Summer Creek Lift Station to the
existing 36" water line on the east side of W. Cleburne Rd during the connection of the
42"tee to the existing 24"and 36"water lines.
• Additional traffic control plan preparation and survey associated with 16" ring connection.
This task will include surveying of approximately 600 LF west of the McPherson/W.
Cleburne intersection, including the Toni Trail/McPherson Blvd Intersection for the
preparation of the traffic control plan along McPherson Street. This task will also involve
multiple additional phases of traffic control along W. Cleburne to accommodate the
construction sequencing and the construction of the valve vault structure. This task will
also involve providing temporary drainage as a result of the impacts to the adjacent bar
ditch and the 24" SD line crossing McPherson Blvd when the additional temporary
pavement widening is constructed. This task will also include additional coordination
meetings with the Traffic Department.
• Additional individual meetings with the City of Fort Worth Staff, Bethesda Water Supply
Company, City of Crowley, & City of Burleson for construction coordination when
transmission main is shut down for the proposed water line connection. This will also
include an additional joint meeting prior to construction. Comments received will be
incorporated into the construction sequencing plans.
