Subject: Amendment Numberl to the Engineering Services Agreement with RJN Group for Wastewater
Collection System Model and Master Plan
RECOMMENDATION
City Administration recommends approval of Amendment Number 1 to the Engineering Services Agreement
with RJN Group for $160,957.58 to update the Wastewater Collection System Model and Master Plan.
BACKGROUND
An accurate wastewater collection system model is critical to preventing future sanitary sewer overflows,
identifying collection system capacity and infiltration/inflow problems before they result in sanitary sewer
overflows (SSOs), and for planning collection system and wastewater treatment plant improvements. The last
model, completed in 1996, established the capacity design criteria for all aspects of the $187 million wastewater
system improvement project. As a result, the City has virtually eliminated wet water SSOs. However, the
collection system deteriorates with time, and the model has not been updated since we performed the WSIP
work. As a result, the City awarded a $499,595 contract to the RJN Group in May 2012, to update the model.
RJN installed flow monitors in the City's sewer collection system in late spring. The intent was to capture both
spring season wet weather and dry summer flows in the collection system. Both are critical to obtaining an
accurate model. Unfortunately, the drought had already set in, and there was not enough rain to develop wet
weather flow information. The effort was not completely wasted as we did obtain excellent dry weather data.
Thus, the model cannot be calibrated. We need at least three rains of greater than 1.5 inches of rainfall,
occurring when the ground water table is normal and the ground is already wet.
DISCUSSION
This amendment provides installation and monitoring of sewer flow monitors intended to collect flows for a 60 -
day period for the City of Fayetteville to capture wet -weather related flows and collect sufficient dry and wet -
weather flows for the City of West Fork. The City's existing permanent flow meters will be utilized during the
project and will be serviced and calibrated by RJN on a regular basis. The City of Fayetteville's permanent
meters will be supplemented by nineteen RJN owned temporary flow meters. In order to prepare for the
possibility of receiving wastewater from West Fork, this amendment also includes provisions to install two
additional flow meters in the West Fork wastewater collection system.
BUDGET IMPACT
Funds are available in project 02017.

AMENDMENT NO. 1
TO
AGREEMENT FOR PROFESSIONAL ENGINEERING SERVICES
BETWEEN CITY OF FAYETTEVILLE, ARKANSAS
RJN GROUP, INC.
WHEREAS, On May 15, 2012, the City of Fayetteville, Arkansas (City of Fayetteville) and RJN
Group, Inc. of Dallas, Texas entered into an Agreement for engineering services in connection with the
Wastewater Collection System Master Plan Update Project. The scope of these services included flow
monitoring to collect dry and wet weather flows, updating the existing Hydraulic Model and
Analysis/Report.
WHEREAS, RJN Group, Inc has proceeded with these services in accordance with the scope set forth in
the Agreement, and
WHEREAS, City of Fayetteville requests that the scope of RJN Group, Inc.'s services be amended to
provide additional flow monitoring services to collect wet weather flows that were not obtained during
the initial flow monitoring period due to severe drought conditions and to install, maintain and provide
report for two (2) additional flow meters in the West Fork Collection System, and
WHEREAS, RJN Group Inc agrees to provide the amended scope of services for a fee increase not to
exceed $160,957.58;
NOW THEREFORE, in consideration of the mutual covenants and Agreements herein contained, City of
Fayetteville and RJN Group Inc., the parties hereto, stipulate and agree that the Agreement for
Engineering Services dated May 15, 2012, is hereby amended in the following particulars:
SECTION 2 - BASIC SERVICES OF RJN GROUP INC
1. ADDITIONAL PROJECT ADMINISTRATION AND MANAGEMENT:
A. PROJECT ADMINISTRATION:
Meet with City of Fayetteville and City of West Fork staff on a periodic basis, to
coordinate upcoming work, and to receive any input from staff. Written documentation
of each meeting will be provided. A total of two meetings are anticipated.
Perform general consultation with appointed City representative on an as -needed basis.
Provide general overview opportunities for City personnel for observing regularly
scheduled flow meter installation and calibration activities.
Fayetteville Master Plan Amendment 1 092612 (3).doc 1 092712
Perform internal project control procedures for the additional period including schedule
and budget control, and quality control review.
2. FLOW MONITORING
The flow monitoring program is intended to collect flows for a 60 -day period for the City of
Fayetteville and that sufficient dry and wet -weather flows will be collected for the City of West
Fork. It is anticipated that sufficient wet -weather data will be collected during this time. Should
sufficient data be collected prior to the end of the 60 -day period, the flow monitoring activities
will be ceased and the City of Fayetteville will only be invoiced for the actual number of days
that the monitoring occurs. The City's existing permanent flow meter will be utilized during the
project and will be serviced and calibrated by RJN on a regular basis. The City of Fayetteville's
permanent meters will be supplemented by 19 RJN owned temporary flow meters. Two
additional flow meters will be installed in the West Fork Wastewater Collection System.
A. METER INSTALLATION
Prepare flow metering equipment for field installation conducting a series of performance
and calibration tests to verify equipment meets operating standards.
A sixty (60) day monitoring period is predicated on obtaining sufficient wet weather
conditions that include at least four (4) storm events of varying rainfall intensities in
order to adequately calibrate the hydraulic model. 19 RJN meters are assumed in the cost
proposal for the Fayetteville Collection system and two for the West Fork Collection
System.
B. METER MAINTENANCE
Maintain the temporary flow meters and City's Permanent Flow Meters over the
monitoring period to achieve at least a 90% uptime requirement. Routine service visits
shall be performed on a bi-weekly basis to include in-situ depth and velocity
confirmations, downloading recorded data, onsite analysis of the data, cleaning of the
sensors, and replacing any defective or deficient equipment. In the event telemetry is
used, data shall be downloaded and evaluated on a weekly basis. Data shall be reviewed
within 24 hours of collection and field technicians will be dispatched no later than the
following working day to correct any issues identified. If any issues are noted with the
City's permanent meters between RJN's regularly scheduled site visits, RJN will notify
the City in order for their staff to service the meter(s).
Fayetteville Master Plan Amendment 1 092612 (3).doc 2 092712
C. METER REMOVAL (TEMPORARY METERS)
In the event the wet weather criteria have been met before the end of the scheduled
monitoring period, recommend the removal of flow meters. If the criteria have not been
observed during the scheduled monitoring period, advise City of Fayetteville and City of
West Fork to consider extending the monitoring period.
D. RAINFALL MONITORING
Acquire access to the existing City of Fayetteville rain gauges and install up to ten (10)
supplemental gauges with 0.01 inch accuracy to satisfy coverage requirements. Service
rain gauges to obtain a continuous record of rainfall conditions during the monitoring
period. One additional rain Gauge will be installed in the City of West Fork.
E. FLOW ANALYSIS AND REPORTS
1) Edit raw data and develop final calibrated flow data for flow meters.
2) Develop depth, velocity and quantity hydrographs for dry and wet- weather flow
conditions.
3) Analyze flow data for sub -drainage basins and develop average daily dry weather
flow diurnal curves and base flow peaking factors.
4) Determine peak inflow rate for selected rainfall events and determine corresponding
rainfall intensity for areas tributary to all flow monitoring locations.
5) Determine peak infiltration rates during high groundwater conditions, if possible.
6) Prepare brief letter report for City of West Fork and submit to City staff.
SECTION 4 — PERIOD OF SERVICE
The completion date for all service included in the amended agreement shall extend until 5 months from
the date that the additional flow monitoring is completed.
SECTION 5 - PAYMENTS TO RJN GROUP INC.
5.1 Compensation
The total payment for the scope of services set forth in the original Agreement plus the additional
services set forth in this Amendment No. 1 is estimated to be SIX HUNDRED SIXTY THOUSAND,
