PROJECT BACKGROUND
The City of Round Rock owns and operates a water treatment plant,referred to herein as the Round Rock Water
Treatment Plant(RRWTP), located at 5200 N. IH35 in Round Rock,Texas. The RRWTP can treat approximately 52
MGD of raw water from Lake Georgetown through three existing treatment plant phases, referenced as Phase III,
Phase IV,and Phase V. Each treatment phase includes a rapid-mix section,followed by flocculation basins,
sedimentation basins,filters,a combined disinfection basin,and ends at several large clearwells and pumping
stations which distribute treated drinking water into the City's distribution system. Construction of the various
Phases has spanned several years,beginning in 1996 and going through 2002. Additionally, multiple smaller
improvement projects have been constructed on the RRWTP site over the years,providing miscellaneous
improvements to various treatment,and piping components.
Currently,the RRWTP uses Alum and polymer chemical addition for coagulation during the treatment process and
Chlorine Gas and Liquid Anhydrous Ammonia for disinfection and residual control. Due to the length of time and
severity of service,several chemical feed lines,the Alum and polymer feed systems,various sample pipes,and
other miscellaneous items have reached their useful life and are beginning to fail,causing maintenance issues
throughout the treatment plant and process.AECOM has carried out and completed the Final Design of the
miscellaneous improvements associated with the Round Rock Water Treatment Plant,and the City of Round Rock
has asked AECOM to develop a proposal for Construction Phase Services for the project.
PROJECT DESCRIPTION
On October 18,2024 AECOM submitted the Final Design Documents for the Round Rock Water Treatment Plant
Miscellaneous Improvements Project,and the City of Round Rock posted the Project for Bidding on October 23,
2024. The Final Design Documents included a rehabilitation of the existing chemical feed system,sample lines to
the laboratory,washdown water at the Sedimentation Basins,and other miscellaneous components that were in
need of repairs and/or replacement. AECOM has been asked to provide Construction Phase Services for the
improvements laid out in the Final Design Documents.
SCOPE OF WORK
The following paragraphs define the specific tasks associated with the Construction Phase Services for the system
and piping improvements described above.
Task 1: Project Management

requirements of the construction contract. Produce meeting minutes for pre-construction conference and
distribute to all attendees.
2. Attend and conduct bi-weekly progress meetings. These meetings will alternate between on-site and
remote Microsoft TEAMS meetings.This proposal is based on conducting a total of twenty-eight(28)
progress meetings for the duration of the construction contract;fourteen(14) in-person meetings,and
fourteen(14)TEAMS meetings. This service will include the preparation of the meeting agenda and
meeting summary minutes.Two(2)hours per meeting for two people are allocated for this task.

treatment phase improvements,confirming the operation and control of the system is consistent with the
design intent,and functions to the acceptance of the Owner.This proposal is based on an anticipated 1-
day operational test for each treatment phase improvements.On-site witnessing of the start-up and
commissioning is anticipated to result in a 4-hour test per treatment phase,and an additional 4-hour test
for the fifth redundant polymer and alum metering pump,for the proposed alum and polymer feed
systems.
