Dear W. Green,
Amendment No.5 to the above referenced contract is necessary due to the increased level of effort
required to field verify and correct discrepancies in the GIS maps and establish lift station control
elevations. The attached letter from Coym,Rehmet&Gutierrez,L.P.with input from LNV, Inc.
summarize the request and costs. Amendment No.5 totals$48,990 for the Phase 1 service areas(Oso,
Greenwood,and Broadway). Based on conversations with CRG and LNV we anticipate additional effort
will also be required for the Phase 2 service areas to field verify GIS discrepancies.
The major tasks included in the city-wide project scope for this Amendment No.5,Phase 1 —Task 12 are:
• Identify areas of concern and possible inaccurate pipe diameter designations with the GIS
shapefiles
• Field verify discrepancies at multiple locations with the Phase I service areas
• Identify areas of concern and possible inaccurate manhole invert elevations within GIS
shapefiles
• Field verify manhole invert elevation discrepancies(such as negative slopes)and update GIS
where needed
• Coordinate lift station control settings to locate and minimize surcharging conditions
The total amount of this Amendment is $48,990 as shown in the breakdown on Attachment "A". The
man hour and fee analysis for this Amendment is shown in Attachment "B". I have also attached the
project schedule for the work as shown in Attachment"C".
If you have any questions or require additional information, please give me a call at (800) 637-0164 or

SCOPE OF WORK
CITY OF CORPUS CHRISTI,TEXAS
SANITARY SEWER OVERFLOW REDUCTION PROGRAM
WASTEWATER HYDRAULIC MODELING
Amendment No. 5
Phase 1 Task 12
CITY PROJECT E10015
BACKGROUND
The approach to the hydraulic modeling of the wastewater collection system is organized around the
City's objectives for this project:
• Reduction in Sanitary Sewer Overflows
• Cost controls and Least Cost Alternatives
• Attainment of long-term Infiltration/Inflow solutions
• Collection System Capacity Assurance
• Regulatory compliance
• Customer satisfaction
GENERAL INFORMATION
A hydraulic wastewater system model will equip the wastewater department with the tool for analyzing
system conveyance capacities,bottlenecks,and potential overflow locations. The hydraulic model is
critically dependent on the accuracy of maps and physical data associated with each pipeline. During
construction of the hydraulic model some GIS data(pipe diameters,invert elevations,lift station control
elevations,etc.)appeared to be in error and field verification confirmed some but not all discrepancies.
To construct a viable model of the collection system required field verifications for all these
discrepancies. This Amendment No.5 provides for a Task 12—Phase I Field Verification.
OBJECTIVES
This amendment will address the following objectives:
• Identify areas of concern and possible inaccurate pipe diameter designations with the GIS shapefiles
• Field verify discrepancies at multiple locations with the Phase 1 service areas
• Identify areas of concern and possible inaccurate manhole invert elevations within GIS shapefiles
• Field verify manhole invert elevation discrepancies(such as negative slopes)and update GIS
where needed
• Coordinate lift station control settings to locate and minimize surcharging conditions
PROJECT PHASING
The Phase I Task 12-Field Verification requires immediate implementation.
MODEL BENEFITS
• Accurate model construction
• QA/QC on model attribute data

BASIC SERVICES—NIA
ADDITIONAL SERVICES TASK 12—FIELD VERIFICATION
The development of a hydraulic model for the six wastewater service areas ensures consistent assessment
of future growth,maintenance and system capital requirements for current and future conditions.
Furthermore,hydraulic modeling will provide the project team consultants with pertinent data to assess
system impacts to various wet weather events and will further enable the project team to test cost
effective repair strategies and alternatives. Modeling will allow the team to conduct a series of"what if'
scenarios that will help determine least cost solutions. These various scenarios take into account the City
of Corpus Christi maintenance and personnel needs,budget,planned growth,capacity issues and can be
used to more accurately design relief and/or replacement lines and optimize system rehabilitation. Task
12—Field Verification is required to verify the hydraulic model connectivity and address possible
discrepancies in pipe diameters,elevations(pipe slopes),pipe and force main layout, lift station control
level elevations,and other GIS discrepancies the must be field verified to confirm accuracy.

times by the CITY or a permitting agency exceeding those anticipated by the ENGINEER'S schedule are
cause for adjustments in the schedule. Any adjustments made to the agreed upon schedule shall be made

RE: Contract Amendment No. 5
Phase I Task 12—Field Verifications
Sanitary Sewer Overflow Initiative Program
City Wide Hydraulic Model — Oso,
Greenwood & Broadway Service Areas
(Project No. E10015)
Dear Mr. Forbes,
We were recently requested to prepare an Amendment to the referenced contract involving
additional services associated with Phase I Hydraulic Models for the Greenwood (CRG),
Broadway(CRG), and Oso(LNV)Service Areas.
During the course of the hydraulic model construction several areas of incorrect data were
discovered within the GIS shape files provided by the City. Additional efforts are required to
identify, field investigate and correct these areas so that the model will reflect the exact existing
conditions of the sanitary sewer collection systems. In general the following tasks will be
required under this Amendment No. 5, Phase I Task 12—Field Verifications:
• Identifying areas of concern and possible inaccurate pipe diameters designations within the
existing GIS shapefiles for each of the Phase I service areas.
• Field verification of pipe diameter discrepancies within the existing GIS for multiple areas.
• Identifying areas of concern and possible inaccurate manhole inverts within the existing GIS
shapefiles for each of the Phase I service areas.
• Field verification of manhole invert discrepancies within the existing GIS for multiple areas.
• Coordination of lift station control settings to locate and minimize surcharging conditions.
The total amount of this Amendment is shown in the table below and supported in the man-hour
analysis breakdowns from each firm,Attachments"A"&"B".
