bil Ig(acctexas.com
Dear Mr.Green,
Amendment No. 8 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 and is requested by LNV, Inc. andCoym,Rehmet&Gutierrez, L.P. Amendment No. 8 totals
$48,310 for the Phase 2 service areas(Allison, Laguna Madre and Whitecap). Based on conversations
with CRG and LNV this amendment will complete the additional services required to field verify GIS
discrepancies.
The major tasks included in the city-wide project scope for this Amendment No.8, Phase 2—Task 13 are:
• Modify the GIS data to represent actual field conditions including revised pipe diameters,
adding missing manholes,correcting invert elevations and verify connectivity.
• Using the modeling software,validate the GIS modifications to GIS data including plotting
of horizontal profiles and engineering analysis of results.
The total amount of this Amendment is $48,310 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
email me at jforbes @pipelineanalysis.com.

SCOPE OF WORK
CITY OF CORPUS CHRISTI,TEXAS
SANITARY SEWER OVERFLOW REDUCTION PROGRAM
WASTEWATER HYDRAULIC MODELING
Amendment No.8
Phase 2 Task 13
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.8 provides for a Task 13—Phase 2 GIS map revisions and model
update.
OBJECTIVES
This amendment will address the following objectives:
• Based on the site visits and field verification of pipe diameters and manhole
connections/inverts,Engineer will modify the GIS data so that it accurately represents the
collection system. This includes revising pipe diameters,adding missing manholes,
correcting manhole/pipe invert elevations,and ensuring proper connectivity between all
manholes and collection lines.
• Engineer will assess and validate the above modifications to the GIS data using the modeling
software. This includes plotting horizontal profiles of the modified collection lines and using
engineering judgment to determine the legitimacy of the revised profile.
PROJECT PHASING
The Phase 2 Task 13-GIS map revisions requires immediate implementation.
MODEL BENEFITS
• Accurate model construction
• QA/QC on model attribute data

BASIC SERVICES—N/A
ADDITIONAL SERVICES TASK 13 —GIS VALIDATION AND MODIFICATION
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
13—GIS map revision 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.

The ENGINEER'S services shall be performed in a timely manner consistent with sound professional
practices. The ENGINEER will complete the work according to the following revised schedule:

The time limits set forth in the schedule shall include allowances for reasonable and expected review time
by the CITY and approval by authorities having jurisdiction over the PROJECT,and shall not be allowed
as cause for delay or adjustments to the schedule. Delays in the design critical path caused by review
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
in writing and acceptable to both parties.
The ENGINEER shall begin work within 10 days of receipt of the executed CONTRACT
AMENDMENT and/or written Notice to Proceed. A schedule of completed work, including a bar graph
schedule showing the percentage complete of each of the items of the scope of work, will be submitted
each month to the CITY.
