STAFF COMMENTS:
In an on-going effort to improve the water system, the City of Coppell is extending the 30" water line,
recently installed up to the intersection of MacArthur and Sandy Lake, to the pump station at Village
Parkway and Kimbel Court. This project will allow us to have an almost direct feed from our pump station
to our new 2 million gallon elevated storage tank at Northpoint and Royal. Our goal is to have this project
complete and the water line operational by the time our peak usage begins. This water line extension was
previously identified in the Water and Sewer self-fimded Capital Projects.
To avoid existing utilities and proposed utilities within the intersection of Kimbel Court and Sandy Lake
Road, it is necessary to construct this 30" water line in the existing Kimbel Court roadway section. Because
of the current state of the roadway and the width of the roadway, it is not possible to maintain traffic on the
roadway during the construction of the 30" water line. Therefore, with the approval of this Change Order
staff is also recommending that Kimbel Court from Village Parkway to Sandy Lake Road be closed during
the construction of the water line. The contractor estimates 30 calendar days for this work. Therefore, staff
anticipates Kimbel Court will be closed approximately six to eight weeks.
Staff recommends approval of Change Order ~ in the amount of $207,256.90 to Ed Bell Construction
Company and closing Kimbel Court during the construction of the water line. Staff will be available to
answer questions at the Council meeting.

Dear Mr. Griffin:
We have reviewed the December 1999 plans for the extension of the Coppell 30" water line from
the end of the current project to the water storage tank facility on Kimble Court. Based upon the
quantities indicated on the plans, the following existing pay items will need to be adjusted for
quantities and/or price:
Item 85 30" RCCP Water Line '~ 929LF ' '~"(-00:00 ~0
Item 86 24" RCCP Water Line 24 LF $150.00 $3,600.00
Item 91' 6" DIP Water Line 26 LF $38.00 $988.00
Item 93 30" Gate Valve 1 EA $35,000.00 $35,000.00
Item 97 6" Gate Valve 1 EA $650.00 $650.00
Item 100 Fire Hydrant 1 EA $2,100.00 $2,100.00
Item 117 Trench Safety 929 LF $0.10 $92.90
The following additional pay items will need to be established:
36" Closure 1 EA SIP, OOO
24" Closure 2 EAI>-°°° 'o~,
1 LS
6" Concrete Pavement Repair
4" HMAC Pavement Repair 1724 SY 2~- ~ ~
Based upon the quantities identified, the total price for this change order is $207,258.90. Our
prices include an $8.46 per LF price increase for the 30" RCCP water line, cost for the additional
survey required, cost for the additional clean up, and cost for the additional bond premium. Due
to the location of the water line, we have priced this work with the assumption that Kimble Court

Re: 30" RCCP Water Line Extension
can be closed; therefore, we have not included any temporary patching of Kimble Court. After
the water line has been tested, EBCC would repair the existing subgrade and have 4" of HMAC
laid to restore the roadway. Our prices specifically exclude repair or replacement of the existing
rock "retaining walls" between MacArthur and Kimble Court.
For simplicity, we attempted to maintain the prices for the existing pay items at their contract
amounts; however, the cost increase for the 30" RCCP necessitated increasing our price for that
item. The labor, equipment, and other material costs for the existing pay items were not
increased. The remaining overhead increases were distributed on the 30" RCCP water line item
and the four new pay items. We will need an additional 30 calendar days to complete this work.
If you have any questions regarding this information, don't hesitate to contact our office.
