Title: Consider executing Quantity Adjustment/Cha;,ge Order No. 2 with Associated
Construction Partners, Ltd. for the Lake Georgetown Chemical Feed System
Project.
Type: City Manager Item
Governing Body: City Manager Approval
Agenda Date: 10/29/2021

Text of Legislative File CM-2021-283
The City owns a raw water pump station on Lake Georgetown, which supplies water to Round Rock's water
treatment plant. In the past several years, invasive zebra mussels have 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 assists with taste and odor
issues, provides manganese control, and assists with zebra mussel prevention in the raw water pipelines.
The project consists of a chemical fill station, a bulk chemical storage tank, a chemical building, and three
chemical feed lines down to the raw water intake.
A field adjustment required an internal coating to protect the building from corrosion, relocation of the
chemical fill station, and the addition of a solenoid box for the chemical lines. A total of 196 days is being
added due to the lead time of materials and construction of solenoid boxes. This additional work outlined
in Quantity Adjustment/Change Order(QA/CO) No. 2 will cost $43,375.92. The City awarded Associated
Construction Partners, LTD with the contract in June 2020 for $1,064,900. QA/CO No. 1 was $23,713.55
and brought the total contract to $1,088,613,55, With the addition of QA/CO No.'s 1 and 2, the new total
contract price is $1,131,989.47.
