MEMORANDUM
FROM THE
DEPARTMENT OF ENGINEERING
To:
Mayor and City Council Members
From:
Michael A. Martin, P.E., Asst. City Engineer
Date:
December 12, 2000
Consider approval of Change Order #5 to the Coppell Road Project #ST 98-01 for the
installation of approximately 236 additional sprinkler heads to the irrigation system to
accommodate the ten foot Hike and Bike Trail in the amount of $41,964.00 to Ed Bell
Construction Company; and authorizing the City Manager to sign.
Ed Bell Construction Company is in the final stages of completing the reconstruction of Coppell Road.
All utilities and concrete paving for the roadway and Hike and Bike Trail have been installed. Major
items that need to be completed by the contractor are the installation of the guardrails, reestablishing the
irrigation systems along the east side of Coppell Road and the placement of sod.
It has been brought to the City's attention by the contractor that the estimated 20 sprinkler heads indicated
in the contract document need to be increased to approximately 236 sprinkler heads. The increase has
been brought about due to the construction of the roadway, the installation of the 1 O-foot Hike and Bike
Trail and sidewalks. When the project was bid it was unclear how much of the existing irrigation system
would be affected. There were no available irrigation plans in the Engineering Department showing the
location of the underground irrigation systems. As the project progressed, it became evident that all five
irrigation systems along the east side of Coppell Road would be affected by the construction.
Because the number of sprinkler heads increased from 20 to approximately 236, staff asked the contractor
to revise its cost per sprinkler head. Currently, the contract has a bid price of $250 per sprinkler head at a
total cost of $5,000. If the same bid price was used for the additional sprinkler heads, the total cost to
adjust the heads would total $59,000. The contractor has agreed to revise his bid price to a total lump sum
cost of $46,964. This amount breaks down to a cost of approximately $199 per sprinkler head, a cost
difference of $51 per sprinkler head. In reality, adjusting the sprinkler heads means: installing new
irrigation lines, sprinkler heads, wiring, and valves; repairing damaged controllers; designing a parallel
system to irrigate on both sides of the sidewalk and Hike and Bike Trail; and any other incidentals
necessary to ensure all systems are fully functional at the completion of the project.
Providing a lump sum price for all the irrigation systems on the east side of Coppell Road ensures that the
contractor will be responsible for making sure all the irrigation systems are working at the completion of
the project.
Staff recormnends approval of Change Order #5 and will be available to answer any questions at the
Council meeting.

In response to your request for revised pricing for the sprinkler head adjustment pay item, we have been concerned
about the open cuded nature of the bid item and the additional risk assumed by EBCC if we lower our price per
head. Thc pay ilcnl description defines the project limits for which EBCC must ensure that all sprinkler systems are
fully functional. The pay item also states that EBCC is responsible for all work necessary to ensure that all sprinkler
systems wilhm Ihe defined limits are fully functional and that all costs associated with ensuring that the sprinkler
systems arc i,dly l'unctioual must be incorporated into the sprinkler head ac[iustment pay item. With a quantity of
only t~vcnt? hca,is set up in th contract, it was our belief that the work would primarily involve investigating the
location o1' Iht heads, capping sprinkler leads at the ROW, and extending those leads into the ROW after completion
of the
Based upon Ibc investigations completed to date and evaluations conducted by our irrigator, it is our belief that 236
heads will be ~cquired and the majority of the problems with the existing systems have been identified. Within the
defined projccl Imfits, EBCC has encountered five separate sprinkler systems that had to be completely removed
and replaced x~ ithin the City's ROW. These systems are spread out over 3500 LF of the project and will require
valve work, xx n'ing, new water line, and new heads. Our lump sum price for this work is $46,964.
As stated p~ cx iously, EBCC has removed the sprinkler systems and and is currently in the process of replacing the
systems. Wc a~ e proceeding with the work necessary to complete this prqiect and the sprinkler work that must be
completed p~ n~t to completion of the parkway. The work in question is withio the scope of work defined by the
sprinkler head a4justment pay item and must be completed prior to completion of the parkway. If it is the City's
iutent to oct pa3 ibr tiffs work or to remove tiffs wink liom EBCC's con~act, then please dflcct EBCC to stop wink
on this item l'Icase note that EBCC has already incurred costs associated with this bid item and would expect to be
