Agenda Item Summary
Agenda Number:
Title: Consider executing Quantity Adjustment/Change Order No. 1 with Associated
Construction Partners, Ltd. for the Lake Georgetown Chemical Feed Project.
Type: City Manager Item
Governing Body: City Manager Approval
Agenda Date: 4/23/2021
Dept Director: Michael Thane, Utilities and Environmental Services Director
Cost: $23,713.55
Indexes: Self -Financed Water Construction
Attachments: CO-QA No. 1_Partial Signed, Map
Department: Utilities and Environmental Services
Text of Legislative File CM-2021-116
The City of Round Rock owns a raw water pump station on Lake Georgetown, which supplies water to
Round Rock's water treatment plant. Invasive zebra mussels have recently been detected in Lake
Georgetown and on the intake structure of the raw water pump station. Zebra mussels have a long history
of attaching in massive quantities to raw water intakes and pipelines, thereby damaging the infrastructure
and restricting flow to the facility.
The purpose of this project is to construct a sodium permanganate chemical feed system at Round Rock's
Lake Georgetown raw water pump station. The sodium permanganate system will assist with taste and
odor issues, provide manganese control, and assist with zebra mussel prevention in the raw water
pipelines. The project will consist of a chemical fill station, a bulk chemical storage tank, a chemical
building, and three chemical feed lines down to the raw water intake.
The City of Round Rock awarded Associated Construction Partners, LTD with the contract in June, 2020 for
$1,064,900.
This change order accounts for electrical conduit crossings that will require a better grade of conduit, time,
and man hours. We will also be adding additional safety features to the building, including guard rails and
safety footings. This change order for $23,713.55 will bring the contract to $1,088,613.55.
Cost: $23,713.55
