AGENDA INFORMATION SHEET
DEPARTMENT: Procurement & Compliance
ACM: David Gaines
DATE: November 16, 2021
SUBJECT
Consider adoption of an ordinance of the City of Denton, a Texas home-rule municipal corporation,
authorizing the approval of a second amendment to a Professional Services Agreement between the City of
Denton and Kimley-Horn and Associates, Inc., amending the contract approved by City Council on January
14, 2020, in the not-to-exceed amount of $1,398,600.00; amended by Amendment 1 approved by the City
Council; said second amendment to provide additional design engineer services and hydraulic analysis in
support of the Northwest Booster Pump Station and Water Transmission Main project; providing for the
expenditure of funds therefor; and providing an effective date (File 6590-081 – providing for an additional
second amendment expenditure amount not-to-exceed $248,500.00, with the total contract amount not-to-
exceed $1,773,400.00). The Public Utilities Board recommends approval (6 - 0).
INFORMATION/BACKGROUND
The installation of a new Booster Pump Station and the associated Water Transmission Main are part of the
overall Water Distribution Master Plan. The Northwest Booster Pump Station and transmission main is a
critical water infrastructure project that will improve water delivery and pressure in the northwest region
ensuring water quality standards are met. This project will also provide a direct connection between the two
elevated storage tanks (Riney Road and Northwest) which will help reduce the time required to fill the tanks
as well as reduce the age (the time it takes for water to travel from the treatment facility to the tap) of water
in the northwest pressure plane.
The original design contract with Kimley-Horn for $1,398,600 was approved by City Council on January
14, 2020, subsequently amended for the first time on January 12, 2021, to include additional services that
were not included in the original contract. As part of the project, additional waterline segments were added
which required additional design services, permitting services, and construction administration services.
Kimley-Horn and Associates Inc. started working on the design of the northwest booster pump station and
the transmission line in early 2020 and since then the underlying future land use assumptions that were used
for developing the design have changed. The change in land use assumptions and considerable interest from
private developers for large commercial/industrial development along the I-35 corridor north of US-380 has
increased the overall demand on the water system resulting in a need for additional capacity. Given that this
project is currently in the design phase, staff recommends updating/revising the design to include the
additional capacity to accommodate future water demand in the northwest region of the City. As such, the
existing scope for Kimley-Horn has to be amended to include additional hydraulic analysis and design effort
to ensure the water lines and their appurtenances are upgraded to meet future demands. This will include
additional design effort for the upsizing of the planned water line and upsizing of the pumps and motors.

The total cost required to cover all the additional effort is $248,500 and staff recommends authorizing the
proposed second contract amendment. It should be noted that the total change orders requested for this
project are roughly 2% of the overall cost of the project.
