Re: WATER MODEL UPDATE
CITY PROJ. NO. (TBD)
Dear Mr. Shoemaker,
In response to the City's request, please allow this letter to serve as our formal contract for initiating
Engineering services associated with the City of Corpus Christi Water model update.
PROJECT DESCRIPTION:
The City of Corpus Christi, Texas, hereinafter called "City", and LNV, Inc. hereinafter called "Engineer", agrees
to the following Contract for Engineering services associated with the above referenced project. The model
update includes input of new distribution infrastructure into the existing model and recalibrating and verifying
the model of the distribution system using data loggers and SCADA.
I. SCOPE OF SERVICES:
A. Additional Services
1. Water Model Update
Description
This effort includes updating and upgrading the City's existing "All-Pipes" model to an "All-Pipes
Valve" model using InfoWater software. The existing model consists of an "All-Pipes" model in
which the total length of system piping is schematically represented without including
hydraulically insignificant valves, fittings, and nodes along the pipes. This existing model
contains model pipe segments that consist of multiple GIS segments which creates a one-to-
many relationship between the InfoWater model and the GIS database.
To maintain consistency with the City's GIS database easily, an "All-Pipes Valve" model will be
setup using InfoWater. An "All-Pipes Valve" model maintains the level of detail of the GIS
database and preserves a one-to-one relationship between GIS elements and their
corresponding elements in the InfoWater model. Due to their one-to-one relationship, there will
be an easier exchange between the City's GIS database and the InfoWater model. However,
SMALL A/E AGREEMENT
EXHIBIT"A"

due to the increased size of the model, scenario processing and demand allocation will be
slower.
Previous demand allocation and model calibration tasks were conducted in the early part of
2012. These tasks consisted of updating existing customer demands based on ONSWTP
production data and customer billing data over a 12 month period from August 2008 to August
2009 (max demand year from June 2008 to June 2011), allocating the customer consumption
data, and calibrating the model with previously collected field data.
a. Standard Operating Procedures Coordination
The NE will:
i. Coordinate a meeting with City Operator personnel to establish an understanding
of the current operating procedures for ONSWTP, system pump stations, storage
tanks, and control valves.
ii. Develop a simple questionnaire to be filled out by City. The questionnaire will
address the main issues regarding standard operating procedures.
iii. Present industry standard general characteristics of typical proposed operating
procedures for modeling, planning, etc.
b. Data Collection/Evaluation
The NE will:
i. Import the GIS database into InfoWater without reduction of any of the
distribution network
1. The GIS database will need to include all pipe segments, valves,
hydrants, pumps, tanks, etc.
ii. Collect and manually insert hydraulic components into the model including
1. Junction elevation — using USGS DEM files and 2 foot contours
2. Tank characteristics
3. Pump curves
4. Pump and valve controls
5. Reservoir levels
iii. Allocate water demands to the model network based on previous calibration
efforts conducted for existing "All-Pipes" model
c. Steady-State Model Calibration
The NE will:
i. Develop the system's standard Roughness Table by placing all pipes into
categorical groups based on diameter, material, and age
ii. Provide City with exhibit identifying required locations for SCADA and Pressure
Logger recordings
iii. Organize and evaluate all calibration data (SCADA and data loggers) previously
provided by the City. Import the calibration data into the InfoWater model.
iv. Perform model calibration with the Calibrator tool so that HGLs are within 5 ft and
flows are within 10 percent as recommended by AWWA M32. Differences
between the modeling results and the SCADA readings are used to calibrate the
model and/or identify locations where field crews may be required to provide
SMALL A/E AGREEMENT
EXHIBIT"A"
Page 2 of 4
additional field investigation to locate valve closures or incorrect data in the
system.
v. Conduct a sensitivity analysis on the key modeling parameters (roughness,
demands, pump curves, etc.) to determine which factors strongly affect flows and
pressures.
d. Extended Period Simulation
The NE will:
i. Input operation parameters collected from Standard Operating Procedures
Coordination.
ii. Establish EPS time interval and run time duration. Input the default demand
patterns, pump controls, and other EPS modeling parameters.
iii. Perform Extended Period Simulation (EPS) calibration with the calibration data
previously provided by the City. System configuration and system condition were
previously calibrated during the steady-state calibration process. For the EPS
calibration process, the focus will be on the model's reaction to changes in
demand over time and the demand itself. To accomplish this, the EPS
calibration process involves refining the consumption diurnal demand patterns for
the various users and better defining the base demand for those same types of
users.

Ill. FEES:
A. Fee for Basic Services. The City will pay the NE a fixed fee for providing for all "Basic
Services" authorized as per the table below. The fees for Basic Services will not exceed those
identified and will be full and total compensation for all services outlined in Section I.A.1-4
above, and for all expenses incurred in performing these services. The fee for this project is
subject to the availability of funds. The Engineer may be directed to suspend work
pending receipt and appropriation of funds. For services provided, NE will submit monthly
statements for services rendered. The statement will be based upon A/E's estimate (and with
City's concurrence) of the proportion of the total services actually completed at the time of
billing. City will make prompt monthly payments in response to NE's monthly statements.
B. Fee for Additional Services. Fee for Additional Services: Fees for Additional Services
shown in the following table are an allowance for potential services to be provided as part of
the project, and are subject to modification by the OWNER based on the actual needs of the
project. Work will not begin on any Additional Services until requested in writing by the
SUBCONSULTANT and ENGINEER, and until written authorization to proceed with the
additional services is provided by the OWNER's Director of Engineering Services. Fees for
Additional Services will be negotiated by the OWNER's Director of Engineering Services, the
ENGINEER, and the SUBCONSULTANT as required. Following successful negotiation of Fees
for Additional Services, ENGINEER will pay SUBCONSULTANT a fixed, not-to-exceed fee for
providing additional services. SUBCONSULTANT's invoice for additional services shall be
based upon SUBCONSULTANT's estimate (and ENGINEER's Concurrence) of the proportion
of the total services actually completed at the time of billing.
Summary of A/E Fees:
