RE: Professional Civil Engineering & Surveying Services
East Alley Wall Replacement
North Palm Beach, Florida
Engenuity Group, Inc. Project No. 03045.193
Dear Mr. Mount:
We are pleased to offer this proposal to render Professional Civil Engineering &
Surveying services in connection with East Alley Wall Replacement in North Palm Beach,
FL (hereinafter called the ‘Project’).
Surveying Services
Engenuity Group, Inc. will prepare a Topographic and Tree Survey pursuant to Chapter
5J-17.050, Florida Administrative Code. The specific survey limits are shown on the
graphic below outlined in red from right-of-way to right-of-way for approximately 4,140
Linear Feet.
See the attached Designated Scope of Services for a specific list of items to be
included on the survey. Additionally, Engenuity Group, Inc will recover sufficient control
to establish the right-of-way lines for the alleyway to show on the survey.
Surveying Fee: $16,420.00
SUE Services
Engenuity Group, Inc. will provide services with due diligence and in a manner
consistent with the standards of the subsurface utility locating industry.
Every reasonable effort will be made to locate all utility systems of interest whether
indicated on record plans available to us or not. However, no guarantee can be made
that all existing utility systems can be detected, and or located.
Our work to collect as-built drawings and related data from utility companies is crucial
for the Project's accuracy and completion. These documents are vital for a thorough
representation of subsurface utilities. However, utility companies may not always
respond as promptly as we'd like, which could lead to delays. While we strive to

minimize these delays and maintain communication with these companies, their
response times and the completeness of their data are beyond our control.
The horizontal location effort will include electromagnetic induction, power source
detection, and ground penetrating radar (GPR) within the sites. The accuracy of these
techniques is subject to the limitation of the available technology and certain factors
and field conditions beyond our control.
Utility locations are provided for design purposes only in an attempt to prevent or
reduce the likelihood of damage during excavation.
Areas to be surveyed with GPR must be level, and free of obstructions.
Use of this service does not relieve interested parties from their responsibility to
make required notifications prior to excavation.
Results are dependent upon field conditions at the time of locating services.
SUE Fee: $9,324.00
Total Surveying Fee: $25,744.00
Technical Limitations of Methods of Locating Subsurface Utilities:
Ground Penetrating Radar (GPR) is a non-destructive geophysical method that uses
radar pulses to image the subsurface. This technique uses electromagnetic radiation in
the microwave band of the radio spectrum, and detects the reflected signals from
subsurface structures. The working principle of GPR involves emitting a high-frequency
radio wave into the ground and observing the reflected signals. The radar antenna
emits the signal into the ground, and when the signal hits a boundary with different
dielectric constants, the signal is reflected back to the antenna. The time it takes for the
reflection to arrive back at the receiver is proportional to the depth of the object
causing the reflection. The reflected signals are recorded by the system and then
processed to create a subsurface profile. The resulting profile can be interpreted to
understand the subsurface conditions, including the presence of buried objects or
changes in material properties. Despite its extensive utility in geology, archaeology,
surveying, and engineering, GPR does have some technical limitations. Understanding
these limitations is critical. Soil and Material Properties: One of the primary limitations of
GPR is the sensitivity to material properties. Conductive materials such as clay, salty
water, or certain types of minerals can absorb and attenuate the radar signal, reducing
the depth of penetration. Non-metallic materials and utilities may not reflect signals as
strongly as metallic materials and utilities. Similarly, heterogeneous materials or
conditions can cause signal scattering, which may complicate the interpretation of the
results. Penetration Depth: While GPR can be incredibly useful for shallow investigations,
the depth of penetration is limited. The penetration depth is determined by the
frequency of the radar wave, with lower frequencies penetrating deeper but providing
less resolution, and higher frequencies offering higher resolution but shallower
penetration. Differentiation Between Similar Materials: GPR may struggle to differentiate
between objects or layers of similar dielectric constants. This can lead to difficulties in
DocuSign Envelope ID: 0963AF91-09E3-4647-9494-E70ED512DCD4
2024 01-31 Proposal
Project No. 03045.193
Page 3 of 8
distinguishing between different layers or objects within the subsurface, potentially
causing inaccurate interpretations. Small Objects: GPR has limitations when detecting
small objects. The minimum size of detectable objects is approximately equal to the
wavelength of the radar wave, which means higher frequency (and thus, shorter
wavelength) systems are required for detecting small objects, sacrificing depth
penetration. Surface and Subsurface Conditions: Surface conditions such as rough
terrain or vegetation can negatively impact GPR data quality. Similarly, certain
subsurface conditions like soil moisture, temperature, and the presence of metallic
objects can cause signal distortion or absorption.
Electromagnetic Induction (EMI) systems are a common method for locating buried
utilities due to their non-invasive nature and potential for high accuracy. EMI systems
work by transmitting an electromagnetic field into the ground using a coil. When this
field interacts with a buried utility, it induces electric currents within the utility,
generating a secondary magnetic field. The EMI system's receiver detects this
secondary field, and the difference between the primary and secondary fields is
analyzed to determine the presence and approximate location of the utility. Depth
limitation: The depth at which an EMI system can detect underground utilities is largely
dependent on the frequency of the electromagnetic wave used. High-frequency
signals can yield detailed information about shallow subsurface features but do not
penetrate deeply into the ground. Conversely, low-frequency signals can reach greater
depths but offer less precision. Soil conditions: Soil conditions can greatly affect the
accuracy of an EMI system. For example, high moisture content or high conductivity
soils can interfere with the magnetic field, making it difficult to accurately locate utilities.
Similarly, rocky or sandy soils can scatter the magnetic field, leading to inaccuracies.
Interference: When multiple utilities are present in the same location, the signals from
each utility can interfere with each other, leading to inaccuracies. This is especially true
when the utilities are close together, such as in congested urban areas. Non-
conductive utilities: EMI systems are primarily designed to detect conductive utilities,
such as metal pipes or cables. Non-conductive utilities, such as plastic pipes, may not
be detectable by an EMI system.
The final deliverable will be an electronically signed and sealed copy of the
Topographic/Tree Survey and SUE Report with accompanying AutoCAD file, which can
be provided within forty (40) business days of receiving authorization to proceed. In the
event of rain delaying our field work, the delivery time will be pushed back the same
number of days.
