DATE: January 12, 2021
SUBJECT
Consider adoption of an ordinance of the City of Denton, a Texas home-rule municipal corporation,
authorizing the approval of a fourth amendment to a Professional Services Agreement between the City of
Denton and Hazen and Sawyer, P.C., amending the contract approved by City Council on July 21, 2015, in
the not-to-exceed amount of $427,368.00; amended by Amendments 1, 2, and 3 approved by City Council;
said fourth amendment to provide additional engineering services and permitting support for the Hickory
Creek Detention Facility and the Hickory Creek Lift Station project; providing for the expenditure of funds
therefor; and providing an effective date (File 5768 – providing for an additional fourth amendment
expenditure amount not-to-exceed $144,150.00, with the total contract amount not-to-exceed
$1,346,964.00).
INFORMATION/BACKGROUND
The City Council authorized the contract with Hazen and Sawyer, P.C. (Hazen) on July 21, 2015, for the
preliminary and final engineering design of the Hickory Creek Detention Facility project (HCDF) which
included concrete storage basins and a peak flow pump station to store peak wet weather flows, and then
discharge back into the Hickory Creek Interceptor when the flows subside. Subsequently, the contract was
amended three times to include several additional tasks such as the engineering design of the West Peak
Flow Storage Basin and Peak Flow Pump Station, engineering design of the Hickory Creek Lift Station
(HCLS) reconstruction, construction-related engineering support services for the HCDF, West Peak Flow
Basin and Pump Station and the HCLS. The current total contract amount (including the three amendments)
is $1,202,814.
The original engineering design for the HCDF project requires a water line to cross the Kansas City
Southern Railroad (KCS) that runs throughout the City. During the design phase of the project, the original
engineering plans for the crossing were approved by KCS and authorized the City to move forward with
the project. Following the completion of the design, KCS updated their design standards and after the
construction of the project began, notified the City that the originally approved crossing design was not
consistent with their current standards and had to be redesigned. The proposed Amendment 4 for Hazen
includes the redesign of the water line crossing which was not originally anticipated and other associated
permitting and construction management tasks. These additional unanticipated services would require
$144,150. The fourth amendment will bring the total value of the contract amount to $1,346,964.
