ACM: David Gaines
DATE: May 4, 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 contract between the City of Denton and Rey-Mar
Construction, amending the contract approved by City Council on May 21, 2019, in the not-to-exceed
amount of $3,418,000.00; amended by Amendment 1 approved by Purchasing; said second amendment to
providing additional construction services for the Hickory Creek Lift Station; providing for the expenditure
of funds therefor; and providing an effective date (File 6894 – providing for an additional second
amendment expenditure amount not-to-exceed $128,170.68, with the total contract amount not-to-exceed
$3,555,833.36). The Public Utilities Board recommends approval (6 - 0).
INFORMATION/BACKGROUND
The existing Hickory Creek Lift Station pumps all the wastewater flows from the Hickory Creek sewer
basin into the State School Interceptor sewer that conveys the flows to the Pecan Creek Water Reclamation
Plant. This lift station was put in service in 1983. The electrical and electronic components of the station
are outdated, and the initial pump station design is deficient as it creates a backup in the Hickory Creek
Interceptor Sewer under normal operating conditions. In addition, there have been service interruptions at
this lift station in 2018 causing large sewer overflows. Cost comparison showed that it was more expensive
to upgrade the existing station compared to constructing a new station.
On May 21, 2019, the City Council authorized the construction contract with Rey-Mar Construction to
begin constructing the new Hickory Creek Lift Station. As part of the last few tasks of the overall
construction project, there is a planned lift station bypass for a period of 7 to 10 days where a section of the
existing wastewater system will be bypassed using temporary pumps and pipes. This will allow the
contractor to work within the by-passed section and replace crucial segments of wastewater infrastructure.
Consistent with the original design, the construction contract includes cost estimates for a basic by-pass
plan but given the critical role of the Hickory Creek Lift Station in the City’s overall wastewater system, a
robust plan (with certain fail-safe components) is required. Additionally, as part of the FM 2181 (Teasley
Drive) wastewater relocation project, staff had recently (6 months ago) experienced significant issues with
a similar basic by-pass on the downstream side of the Hickory Creek Lift Station. As such, staff
recommends moving forward with a robust by-pass plan which will incur additional costs.
The additional cost of the added elements related to the by-pass as well as certain other minor changes
that are included in the change order is listed below.
