SCOPE OF SERVICES
W The Field Scope of Service for the Leak Survey is understood to be the following:
M.E. Simpson Co., Inc. will furnish all labor, material, transportation, tools, and
t equipment necessary to survey the water distribution system areas selected by the
City of Elgin. M.E. Simpson Co., Inc. shall be required to provide such skilled and
` ` trained personnel and equipment necessary to complete the work herein specified.
There will be a minimum of Two Persons per team working on the survey at
all times.
At
�r
Leak Detection has come a long way since the early 1900's.
♦ Work in an orderly and safe manner to insure protection of the local residents,
Utility employees, and the Field Staff so that no avoidable accidents occur.
♦ All Field Staff will have readily observable identification badges worn while in the
field.
♦ The leak detection equipment to be used will be that which was described in the
"Equipment to be used" section.
♦ Initially listen to all fire hydrants. all main line valves, and when necessary,
selected service connections in the entire distribution system with the S30
electronic listening device or the L-Mic, by making physical contact with the
valve, hydrant, pipe, or B-box. (Listening points that are not accessible will be
given to the Utility and when corrected they will be listened to.) This will be done
on the Utility's distribution system.
♦ Listening distances will not exceed 500' between points. I.E.:, valves, hydrants,
service valves or meter settings will be used with preference of listening points in
order as follows; direct contact with the pipe, main line valves, hydrant valves,
hydrants, then service valves or meter settings.
♦ Valve vaults full of water may be pumped out to facilitate listening. Sometimes
full vaults can mask leak noise.
♦ Large diameter pipe (18"-36") may need to have additional listening performed
by listening directly above the pipe at intervals of 6-10 feet.
♦ All accessible points along PVC water mains will be physically listened to
including services, main line valves, and hydrants.

SCOPE OF SERVICES
♦ A"suspected leak" log shall be maintained indicating all areas where suspected
leak noise was heard. This log will be reviewed when the Project Team is
verifying the suspected leak area for confirmation of the actual existence of a
leak. This log will be a part of the periodic reports turned into the Utility
regardless of an actual leak located in the area or not, with an explanation of the
noise source.
♦ When leak noise has been detected and or suspected, the Project Team will verify
the suspected area a second time to confirm the noise. At least four hours will
pass between the initial listening of the area before a second listen and
confirmation is attempted.
♦ The Project Team will line locate the water main and service lines in the
immediate area so the correct pipe distances can be input into the leak correlator
and also so that the Water Utility will have an idea of where the water main is
located prior to excavation. Non-metallic pipe locations will be "interpolated" as
best that can be identified, given the line location of metallic services, Utility
knowledge of the area, or other information regarding the actual location of the
main.
+� ♦ The Project Team will use the following Electronic Leak Correlators (either a FCS
Accu Corr/ Digi Corr or Vivax Metrotech HL6000X leak correlator), to determine
if a leak is present and use the same equipment to pinpoint the leak.
♦ For PVC water mains only the FCS Accu Corr/ Digi Corr leak correlator, will be
used for correlations because of the ability for these correlators to be able to
analyze the particular sound frequencies inherent to PVC pipe.
on uc ng n a is enmg survey 'T'marks the spot for excavation
♦ The leak location will be marked in the field (on the surface) using
environmentally formulated Precautionary Blue paint.
♦ The Project Team will document all leak locations with a diagram indicating the
1�1 location of the leak. Other information related to that correlation will be included
as part of the field sheet such as the filters used for the correlation, line
locations, distances between sensors, etc.
♦ The field sheets will be copied, and turned into the assigned Water Department
Manager daily or an agreed time period so the leak can be dug and repaired
immediately. They will be classified as to the potential severity of water loss, as
well as potential danger to the general public.
♦ The locations of leaks requiring immediate attention (immediate threat to life,
injury or traffic) will be turned in as quickly as possible to facilitate the repair
process.

SCOPE OF SERVICES
♦ "Ground miking" will not be used as the primary determination for leak
locations. Grounding miking will be done per Utility request, or when it has been
deemed to be the most efficient means to listen to the water main running under
ground. Large diameter mains (18" - 36") may need this additional evaluation.
This method may be used to assist in confirmation of a leak location. However,
"aground miking" is solely dependent on conditions beyond the direct observations
Ir of the leak technician such as soil conditions and composition, water table, depth
of pipe bury, assumed location of the water main (such as concrete pressure
pipe) and compaction of pavement material causing leak sounds to scatter and
echo or simply be absorbed.
R ♦ The Project Team will report daily or per request of the Utility, to the assigned
Utility Manager and go over the progress of the previous day, as well as cover
what will be surveyed the current day.
♦ It may be necessary to conduct parts of the Leak Survey during "off hours" such
as at night. This may be required in areas of high traffic volume where traffic
noise may affect the ability to detect leak noise, and traffic volume may affect
the ability of the Project Team to be able to safely access main line valves in the
middle of the street. The Project Team will give 24-hour advanced notice of intent
to survey a particular area that may require after hours surveying or nighttime
surveying. This is so the Utility can plan for the area to be surveyed, give
notification to the Police department, as well as other Public Works Divisions as to
the activity that will take place.
♦ A progression map shall be maintained for each section under survey indicating
leak locations on the map. This will be especially helpful in quickly determining
leak locations that correspond to the field leak diagrams turned into the Utility.
♦ As a part of the leak program, mapping discrepancies found on the current water
atlas will be noted and included as a part of the final report so the Utility can
P make needed corrections. This will be included as a part of the periodic reporting
to the Utility, thus enabling the Utility to keep up with mapping corrections.
♦ Distribution assets found to be in disrepair such as issues with hydrants, valves,
and service lines, will be noted and turned into the Utility.
♦ Leaks verified on the customer's side of a service shut-off will not be located
beyond the shut-off. If a leak appears to be on the Customers' side, the Utility
will be notified first, then the customer notified and permission granted prior to
w the water being shut off even for short periods of time where possible and as
time allows, as well as the ability for the customer to respond.
♦ If the Utility requests leak locations beyond the service shut off on the customer's
side of the service line, this will result in an additional charge to the leak survey
based on an hourly rate and this service must be agreed upon between the Utility
and M.E. Simpson Co., Inc. prior to the start of the survey.
♦ Valves and hydrants will not be operated without Utility permission. Valves and
hydrants that break during this type of operation are the sole responsibility of the
Utility. M.E. Simpson Co., Inc. cannot be responsible for valves and hydrants that
break due to pre-existing conditions.
♦ The Utility is encouraged to dig up and repair the leaks located as soon as
possible so that the area may be re-surveyed while the Project Team is still
working on the survey in that general geographical location to ensure no other
leaks are present in that area.

SCOPE OF SERVICES
GPS OF LEAK LOCATIONS
' Once leak locations have been confirmed, the M.E. Simpson Co., Inc. Project
Team will perform the following:
♦ The Project Team will collect GPS Coordinates of all leak locations assessed
using the above "Scope of Work"
♦ The Project Team will work with the Utility to develop a "data dictionary" which
will define the information to be collected for each leak location. The Data
dictionary shall have the following but not limited to:
o Date and time the information was gathered.
o The unique identifying number for each attribute consistent and
compatible with system presently employed by the Utility.
o Location for each attribute referenced by Northing and Easting
coordinates generated from the GPS location in the Utility's local State
Plane Coordinate system, as well as Latitude and Longitude.
o Type of Attribute (main break on pipe, mainline valve leak, hydrant
leak, service leak).
o Offset information if the attribute needs to have the location
determined by an offset coordinate due to blocked signals from the
GPS satellites.
! o Any other data required to be collected as part of the attribute data set
as defined by the Data Dictionary. This Data Dictionary will be
assembled by the Project Team and the Utility.
♦ The accuracy of each GPS location will be sub-meter.
♦ The location of"offset" GPS locations will be accomplished by use of a Laser
Rangefinder with an accuracy of 1/10th of a foot with an automatic Electronic
Compass coupled to the GPS data collector. This is so that a bearing and distance
from the offset location to the target GPS location can be recorded as part of the
attribute data. This will allow coordinates to be generated in high tree canopy
and urban canyons where normal coverage would not be possible.
♦ GPS locations will need to have readings from at least four satellites in
position and a reading from a local GPS beacon, or five satellites for the position
to be considered accurate as a differentially corrected GPS location.
♦ "PDOP" readings need to be less than S. "PDOP" readings greater than 5 will
not be considered as accurate locations.
♦ A minimum of 30 readings for each position shall be taken.
♦ Position of the GPS satellites shall be given primary consideration. The
position of the satellites shall be recorded as part of the data. If the satellites are
`p low on the horizon, it is expected that the project team will wait until the position
is better before attempting to gather the GPS position. Data collected with the
satellites low on the horizon and/or poorly distributed shall not be considered
valid.
♦ The information collected will be compiled into the Pathfinder Office or
TerraSyncT"' software database with the ability to export the information into a
format acceptable to the Utility such as Microsoft Access, Microsoft Excel, .DXF
file, or .SHP file for use in the Utility's GIS system or CAD mapping program, and
also included in the Leak Location Excel database.
♦ All locations will be differentially corrected for accuracy. A stationary
beacon or mobile beacon can be set up to allow differential correction. All data
will be "Post-Processed", so that a comparison can be made to a Local stationary
GPS receiver. The locations of the stationary GPS stations can be obtained from
the Internet. The particular stationary GPS receiver shall be listed in the final
report as the station used for differential correction. This will allow for a greater
accuracy of the GPS locations.

SCOPE OF SERVICES
Quality Control and Accuracy of Leak Locations
The level of accuracy of leak detection is a matter of taking in all the above
considerations and applying those considerations to each individual potential leak
location as it is being evaluated. Any statement made as to the level of accuracy of
leak locations must be considered based on the individual conditions of each leak.
Leak surfacing at intersection Hidden leak running into drain tile
Locating leaks on a distribution system can be very challenging. It is not a perfect
science. Pipes and fittings can leak for a variety of reasons (age, poor installation,
material failures, bad soils, etc.), and the ability to locate leaks is dependent on the
stated variables listed in the "Project Approach". By employing a strict methodology
in the field for conducting a leak survey, these variables can be accounted for and
mitigated. The depth of experience of the Project Team is extremely important to
maintaining the ability to have accurate locations of leaks. Additionally, crews work
as Two-Person Teams in the field, double checking the progress of the work as the
survey progresses. The systematic procedure for leak confirmation has been stated
in the Scope of Field Service and is restated here.
"Suspected leak areas are always listened to a second time, preferably at a different
time of day than originally listened to. The mains and services will be line located to
insure correct pipe distances are used for the correlations. Correlations may need to
be performed several times with several configurations to insure all the possible
scenarios have been covered. Sewer manholes may need to be opened and flows
observed. If there is any doubt as to the existence of a leak, the area may be
checked and correlated at different times to rule out water usage or other factors.
The progress of the survey will be monitored by the use of daily logs and a
progression map with suspected leak noise indications marked and possible leak
locations will be maintained. Field leak location forms will be turned into the Utility
according to the agreed schedule. The Project Team will follow up on leak locations
by monitoring the repair schedule of the Utility. That way in case a potential leak
location is wrong, the Project Team can return to the site and determine why the
leak location was incorrect, and correct it. This means maintaining a good level of
communication between the Project Team in the field, and the Utility. As a matter of
Quality Control for leaks in the field, the two Correlators (Accu-Corr and Digi-Corr)
have the distinct ability to be able to detect and pinpoint more than one leak in the
same relative area' thus allowing better leak coverage and insuring that one leak is
not"masking" another leak in the same area. The use of progress reports and
i6 meetings will allow for open discussions of problems encountered so solutions can be
examined."

PROPOSED SCHEDULE
Proiect Schedule
Proposal Due: March 21, 2014
Possible Notice of Award: April 2, 2014
Notice to Proceed: April 25, 2014
Kick Off Meetina and Commencement of work: May 5, 2014 or agreement of Utility.
Meet with Utility staff to go over project goals and objectives. Field work will begin on day
agreed upon by the Utility and M.E. Simpson Co., Inc.
Fieldwork to be completed and documented: Assume one (2 person crew), 17 - 20
days in the field for completion of field work for the acoustic leak survey and all pinpointing
per"Scope of Work". Additional leak detection work outside of the leak survey area will be
based on fees as stated in the Cost Proposal and may cause a shift in the completion date.
It is assumed the water main sizes, types, and lengths are correct as stated by the Utility.
Daily Work Hours
Normal"on site" daily work hours will be 7:00 AM to 4:30 PM. Any work that needs to be
performed outside the normal work hours will be discussed with the Water Superintendent
at least 24 hours in advance (such as night work).
Daily Leak Reporting: The Field staff will meet with assigned Utility staff daily or as
needed and determined by the assigned Utility Manager. Leaks needing immediate attention
will be documented and submitted immediately for the Utility's attention. Minor leaks (such
as hydrant leaks, service line leaks, valve packing leaks) will be reported daily for
scheduling of repair. Photo copies of leak locations will be turned in to assigned Utility
Manager daily or as agreed upon by, prioritized by leak severity.
Microsoft Excel format Leak logs will be turned in weekly (e-mailed or printed) or as agreed
upon to the Utility. Leak logs will have all suspected leak areas identified whether an actual
leak is confirmed or not. If a "no leak" condition is confirmed, the noise source will be
identified. These logs will be included as part of the final report.
Final Leak Resorts: The final summary report will be available 30 work days after field
work has been completed for the program or August 8, 2014. This report will have all the
leak location drawings and suspected leak logs compiled during the course of the project. In -
addition the final report will have a summary of the entire program with quantified levels of
project payback detailed.
