SCOPE OF SERVICES FOR
VILLAGE CREEK WATER RECLAMATION FACILITY
FINAL BIOSOLIDS MASTER PLAN AND IMPLEMENTATION SUPPORT
CITY PROJECT NO.: <XXXX>
AMENDMENT1
The scope set forth herein defines the work to be performed by the ENGINEER in
completing Amendment 1 related to the Village Creek Water Reclamation Facility (VCWRF)
Final Biosolids Master Plan and Implementation Support Project (Project). Both the CITY
and ENGINEER have attempted to clearly define the work to be performed and address the
needs of the Project.
WORK TO BE PERFORMED
Contract Number 50018 was executed by the CITY and ENGINEER on November 27, 2017.
ENGINEER has performed services in support of the Biosolids Master Plan in accordance
with the contract including the scope of services. Task 4, Additional Services, provides that
the ENGINEER may perform additional services with specific direction from the CITY Project
Manager on a task by task, time and materials basis.
Based on a request from the CITY Project Manager, CI-12M prepared this Amendment for
performance of additional services for modeling and preparation of a Wastewater
Preliminary Engineering Report in accordance with Texas Water Development Board
requirements identified in TWDB-0556.
TASK 4.1. ADDITIONAL PROJECT MANAGEMENT.
ENGINEER shall ensure efficient and effective use of ENGINEER's and CITY's time and
resources.
Managing the Consultant Project Team
• Two additional meetings between CITY and ENGINEER to 1) Discuss key sections
of the Draft Engineering Feasibility Report and 2) Obtain CITY feedback on the
submitted Draft Engineering Feasiblity Report.
• Task and allocate team resources to manage services related to this Amendment.
Communications and Reporting
• Update the Project Schedule to rebase the project to include this additional task;
monthly updates are included in the original authorization.
Task 4.1 ASSUMPTIONS
• Two additional 2-hour team meetings with the CITY attended by up to 2
ENGINEERING team members.

• The rebased project schedule will be prepared in Microsoft Project and
submitted with the monthly report.
Task 4.1 DELIVERABLES
• The updated schedule will be submitted with the typical monthly status report
TASK 4.2. ADDITIONAL BIOSOLIDS MASTER PLAN SERVICES.
ENGINEER will finalize the existing Draft Long-term Biosolids Master Plan (BMP) and
perform additional work for the CITY as follows:
4.2.1 Additional Biosolids Projections/Modeling
ENGINEER will provide Additional Engineering Services to update the existing GPS-X
process model and biosolids projections for the Village Creek WRF. This is an extension of
existing Task 2.4, Update Biosolids Projections, and it includes work and effort that was not
intended in the original scope of work. Additional tasks include:
1) Review and analysis of historical plant influent parameters to update projected
service population, flow projections, influent loads, and per capita influent to
VCWRF. ENGINEER to analyze the data to select a representative time period for
use in model calibration. The original scope intent was to use the 2014 BMP's annual
average flow and load projections rather than update them for model development.
2) Review and analysis of historical data provided by the City to determine typical
wastewater quality characteristics, changes to operating condition, and water quality
parameters throughout the treatment process including primary clarification, aeration,
secondary clarification, thickening, digestion, dewatering and other processes. The
original scope intent was to update the model based only changes to operating
conditions as provided by City staff without extensive analysis of historical data.
3) Develop up to three model calibration iterations for annual average conditions.
ENGINEER to work with City staff to review and fine tune the calibration to increase
its accuracy, and to better reflect anticipated future operating conditions.
4) Develop up three sets of model validation results, testing the calibrated model
against historical data for different time periods including annual average and
monthly average conditions. This will test the accuracy of the model calibration for
various time periods and operating conditions as a QA/QC step with City staff.
Identify refinements to the model and calibration to more accurately reflect
anticipated operating parameters, and establish more confidence in the model's
projection of solids quantities for future operating conditions.
5) Comparison of GPS-X modelled max-month flow and load projections with those
projections developed using peaking factors. This will be a QA/QC step to establish
confidence that the model reasonably agrees with historically observed peaks.
Because the model is not accurate for Max-Week conditions, this verification will give
more confidence in the reliability of Max-Week projections based solely on peaking
factors.

Task 4.2.1 ASSUMPTIONS
• No additional assumptions.
Task 4.2.1 DELIVERABLES
• The original project scope Task 2.4 includes a Technical Memorandum (TM) that
describes the results of the modeling effort. As part of that TM, with this
Amendment the TM will also describe the results of the historical data analyses,
revised influent flow and load projections, selection of peaking factors, model
validation results, and additional model assumptions made. Results will also be
described in the Task 2.8 deliverable, Final Biosolids Master Plan Report, and in
the Engineering Feasibility Report described below in Task 4.3.
4.2.2 Additional Alternative: MAD Followed by THP then MAD
At the City's request, ENGINEER will provide Additional Engineering Services to evaluate
one more technology alternative for comparison with those already included in the scope of
work: Mesopilic Anaerobic Digestion (MAD) followed by Thermal Hydrolysis Pretreatment
(THP) then Post-MAD, potentially followed by air drying. This is an extension of existing
Task 2.6, Alternatives Evaluation, and it includes work and effort that was not in the original
scope of work.
Task 4.2.2 DELIVERABLES
• Results of this analysis will be incorporated as an additional section into the
existing Task 2.6 deliverable: TM 2. This will include a description of the
technology, conceptual sizing, cost estimate, evaluation using the established
non-cost scores, and comparison to other Alternatives. Results will also be
described in the Task 2.8 deliverable, Final Biosolids Master Plan Report, and in
the Engineering Feasibility Report described below in Task 4.3.
TASK 4.3. ENGINEERING FEASIBILITY REPORT(EFR)
The CITY desires to seek Texas Water Development Board (TWDB)funding for facility
construction. TWDB requires that engineering analysis be documented and formatted in a
prescribed manner as set forth in TWDB-0556, Guidance for the Preparation of Wastewater
Engineering Feasibility Reports. ENGINEER will develop an Engineering Feasibility Report
as set forth in TWDB-0556 based on the technical content contained in the initially scoped
TM and "VCWRF Biosolids Master Plan Report"deliverables.
Wastewater Engineering Feasibility Reports include some information in addition to that
included in the scope of services for the Biosolids Management Plan Report. Effort over
and above that originally anticipated include:
• Additional details, maps and figures regarding facility siting
• Broadened discussion of existing and forecast needs and operational issues
• Integration into the report of water sources, ownership, and adequacy of water
supply for the planning period which will be provided by the CITY
