Understanding of Responsibilities and Scope of Services
IMS has been the Village’s pavement management consultant for nearly 20 years. For each project over
the years, IMS mobilized our RST for surface distress data collection and a Dynaflect for structural
testing on 70 miles of Village-maintained roads. The Village transitioned from the legacy IMS software,
PavePRO, to the Easy Street Analysis (ESA) software during the 2020 project. The pavement condition
data is analyzed and loaded to the pavement management software (currently ESA) for the Village staff
to develop maintenance and rehabilitation programs. IMS has performed 6 network-level pavement
condition assessments.
The Village of Deerfield has a pavement network that consists of approximately 70 centerline miles of
roadways. For this project, pavement condition data will be collected on all roads in a continuous and
linear manner, on days with optimal weather and light conditions using our LCMS-2 system in
accordance with modified ASTM D6433 definitions of the distress types. This includes the following
common distresses for asphalt and concrete:
ASPHALT CONCRETE
Alligator (Fatigue) Cracking Corner Breaks
Block Cracking Blowup/Buckling
Reflection Cracking at Joints Faulting
Longitudinal and Transverse Cracking Patching
Edge Cracking Punchouts
Patching Pumping
Rutting Shrinkage Cracking
Shoving Spalling
Raveling Linear Cracking (Longitudinal,
Transverse, and Diagonal)
Potholes
Weathering
Additionally, the Village desires to collect pavement structural data as well. Historically the Village has
collected structural data for its road network. IMS has upgraded our structural testing equipment. We
have introduced the Fast Falling Weight Deflectometer (FastFWD) to replace the Dynaflect. As with the
transition to state-of-the-art surface testing equipment during the 2020 project, the FastFWD will
provide superior results on the performance of the base and subgrade. This is critical data that provides
an overall pavement condition number that integrates both surface condition data and structural data
into its M&R plans.
IMS will offer continuity with the data collection protocols and directional testing for the Village. We will
mobilize our RST to collect pavement distresses and roughness data and mobilize our FastFWD for
structural testing in conjunction with our planned work in Chicagoland. IMS also maintains local
calibration sites and has enhanced our Quality Assurance Program since our previous project with the
Village.

Semi-Automated Pavement Surveys Using State of the Art Pavement Data
Collection Vehicles
IMS owns and operates a fleet of eight Road Surface
Tester (RST) data collection vehicles, which provides
us with two critically important capabilities: project
scheduling flexibility and equipment redundancy. We
have the staff, equipment, and expertise to
successfully complete the project for the Village.
The RST is equipped with specialized data collection
technology, including a second-generation
Pavemetrics Laser Crack Measurement System (LCMS-
2) for collecting downward facing, laser illuminated
pavement imagery, a Point Gray Ladybug 5+ 30MP
360° camera for collecting high resolution outward facing right-of-way imagery, and a navigation grade
inertial navigation system. Our field operations division prioritizes preventative maintenance and
upkeep to ensure the data we collect consistently meets standards. Should an unexpected issue arise,
our parts department is well stocked with replacement inventory and our full-time support team is
ready to make repairs and maximize our time out on the road collecting data.
Nondestructive Structural Testing
IMS offers additional pavement testing techniques to
enhance decision making and prioritization. IMS
performs nondestructive structural testing for
agencies where the history of mill and overlays, soil
conditions, and other environmental factors require
additional information to determine the most cost-
effective rehabilitation strategy. IMS added a Fast
Falling Weight Deflectometer (FastFWD) to its fleet of
pavement testing equipment for objectively,
repeatably, and rapidly assessing the structural
integrity of pavements. The FastFWD applies a
dynamic load to the pavement surface that simulates
traffic loading and measures the response
(deflection) of the pavement. This information is
used to assess the load carrying capacity and remaining service life of the pavement. Testing with the
FastFWD is five times faster than with its counterparts.

Right of Way
Asset Collection
Imagery collected during the
RST survey can be used to build
ROW asset inventories and
condition assessments for signs,
signposts, curb and gutter,
sidewalks, ramps, striping, and
many other assets. A
subconsultant will be added to
the team if this service is

Friction Testing IMS can deploy a surface friction
tester (SFT) to measure the
frictional characteristics (skid
resistance) of the pavement
surface. This type of testing is
typically done to evaluate
stretches of pavement that may
be prone to accidents or may
have a mix design that is
susceptible to polishing and/or
loss of macrotexture.

Similar Project Experience
IMS is a licensed Illinois engineering firm, and
we bring significant regional experience and
expertise to meet the Village’s pavement
condition assessment, right-of-way asset, and
pavement management needs. As previously
mentioned, the IMS technical team is comprised
of 10 pavement engineers, six possessing
doctoral degrees in pavement engineering and
two of whom are licensed professional
engineers in Illinois. Together, our team of
pavement engineers has 149 years of
experience.
Our pavement engineering team is supported by
our team of 18 trained and experienced
pavement technicians. Eight of our technicians
are independently certified Pavement Condition
Index (PCI) raters, and the majority have
experience evaluating pavements in Illinois. Collectively, our team of pavement technicians has more
than 200 years of combined experience. Altogether, the IMS team brings nearly 350 years of pavement
and asset management experience to the table.

Proposed Project Approach
The IMS project approach for pavement condition and asset inventory projects typically follows the
eight steps shown in the graphic below. In this section, we detail the specific tasks and milestones that
will be required for the successful completion of this project.
IMS assigns seasoned pavement engineers as the project managers for all our projects. We believe it is
imperative that the project manager have the requisite technical and domain knowledge – as well as
practical project management experience – to lead the team. Our project management process is based
on thorough planning, proactive management of schedules, and constant communication. The result of
effective project management is higher quality with respect to project deliverables and satisfied
stakeholders.
Project Initiation & Kickoff Meeting
IMS has standardized a project approach based upon our 38 years of pavement management experience
and the subsequent lessons learned after performing hundreds of projects. Detailed conversations with
our clients allow us to tailor a solution to the specific needs of an individual agency.
A prerequisite for a successful project is an initial project meeting with the Village team members and
the IMS team. This early communication is critical to ensuring that we are fully aligned with the Village’s
overall vision for this project as well as the specific data needs for the Village. Through this project
initiation process, we will prepare the project plan for overall implementation. The plan includes:
• Contacts and stakeholders
• Measurable tasks and milestones
• Project approach and specific data collection methods
• Allocation of resources, including personnel and equipment
• Deliverables and schedule
• Performance and schedule risks
Deerfield, Illinois

We will ensure that the plan remains current with any further data needs. Our Project Initiation Form
and GIS Setup Form are part of our process, where the outcome will include a final project plan and an
approved schedule in collaboration with the Village’s staff and stakeholders. This plan is established
before any data collection begins. Project requirements are incorporated in the two project success
documents. The project success documents ensure transparency and act as a reference point to ensure
all stakeholders are accounted for and involved.
GIS Survey Mapping & Network Referencing
Data collection is unique in every jurisdiction, varying by network complexity, the mix of urban and rural
roadways, type of terrain, schedule constraints, and most notably, the analysis and data delivery
requirements. To facilitate a standard approach that yields deliverables tailored to our clients’ needs, we
have developed our Unify™ Suite of collection, processing, and viewing software. The comprehensive
software relies on street centerline GIS data provided by the Village to build all successive processes
which include calibration, collection, analysis, and reporting. The Unify Suite™ eliminates the need to
use numerous scripts and transformations to produce the geodatabase and tabular deliverables.
Our technical team will review the Village’s road network files (expected in an ESRI GIS file format) that
define the routes to be collected. The GIS will be reviewed against any existing pavement database
street segments and roadways. If discrepancies arise, they will be noted and discussed for resolution
with the Village before the start of data collection. The finalized road network will be loaded into the
Connect™ software, which defines the pavement network segmentation and attribution to be collected
and delivered, minimizing routing problems and location errors. The GIS files will include attributes such
as Road Section ID, Street Name, Street Type, beginning description, ending description, start reference,
and end reference for each segment.
Our UnifyTM software automatically extracts data from the various sensors on the data collection vehicle
and combines it with location information and imagery. The Unify™ workflow provides easy field data
collection using the RST and Drive™ software onboard each vehicle, and the data is seamlessly
transferred to Connect™ for spatial analysis and processing. Unify™ provides our clients with a perfect

match between the Village’s existing GIS and the resulting condition data and allows us to configure our
data deliverable in many formats that are ready to use by pavement management software (PMS), GIS,
and other management systems.
Connect™ allows for daily progress tracking, as the field crew uploads the files from the day’s collection
for the office staff to match against the network for location and completeness. For larger projects, it is
common practice to divide a large network into smaller, more manageable sections, such as council
districts or maintenance areas.

Pavement Condition Survey
Our two-person field crews will collect both outward facing and downward facing pavement imagery,
using one of our RSTs equipped with LCMS-2 3D pavement imaging technology. Pavement surface
distresses including load cracking, block cracking, rutting, raveling, reflective cracking, loss of section,
bleeding, edge distress, and patched areas as well as right-of-way imagery will be collected on a
segment-by-segment basis, with each distress being captured by type, extent, and severity. The data
and imagery that is collected is then linked to the Village’s existing GIS data.
The LCMS-2 system is the highest resolution 3D pavement scanning technology available. Each LCMS-2
system relies on two downward-facing, high-resolution 3D cameras. Combined, the two 3D cameras
capture continuous downward imagery for more than a standard lane width. The cameras are coupled
with downward-facing lasers that provide constant and consistent illumination of the pavement surface
regardless of ambient lighting conditions. The impacts of shadows from trees, buildings, or simply
overcast sky conditions are eliminated by the laser illumination.
The 3D cameras can detect one-millimeter-wide cracks and full-lane-width rutting, as required by ASTM
D6433, on the pavement surface at speeds up to 65 mph. Due to the versatility of the LCMS-2
technology, the automated pavement condition survey will be performed at posted speeds, and traffic
control will not be necessary for the data collection effort. Pavement data collection and imagery
surveys are expected to progress at a rate of between 30 and 50 miles per day for the Village.

The IMS team then processes the collected data using a combination of advanced analytical tools and
QC/QA checks to determine accurate and repeatable PCI values for each roadway segment. IMS offers a
rigorous, manual QC/QA performed by IMS’ certified Pavement Condition Index (PCI) raters to further
ensure the data accuracy should the Village opt for it. Furthermore, we deliver our PCI ratings and
supporting data (distress information, rutting, and IRI values) in both spreadsheet and GIS formats for
easy review. The data that we provide may be used immediately for decision making or be imported into
any pavement management system.
ASTM D6433 Pavement Condition Data Processing and QC/QA
During and following the data collection effort, our team will evaluate all collected pavement imagery
and surface measurements to arrive at Pavement Condition Index (PCI) values. This is a six-step process
that includes the following tasks:
1. RoadInspect™ Pavement Distress Detection – Cracks, rutting, and other pavement distresses
are automatically detected in both the 2D and 3D pavement images. IRI values are also
calculated at this time. (Note: The RoadInspect™ software was developed by Pavemetrics, the
firm that manufactures the LCMS-2 technology.)
2. IMS Pavement Distress Classification – Pavement distresses detected by the RoadInspect™
software are then classified by type (e.g., alligator cracking, bleeding, edge cracking, etc.) and
severity (e.g., low, medium, or high) based on predefined criteria (e.g., ASTM D6433). IMS uses
our UnifyTM Suite that includes rule-based algorithms in conjunction with artificial intelligence to
accurately classify pavement distresses.
3. IMS PCI Calculation – Within the UnifyTM Suite, PCI values are determined for each roadway

segment using a scale from zero (0) to one hundred (100) as defined in ASTM D6433.
4. IMS Quality Control (QC) –The IMS project manager then
does a review of the data and works with the QC team lead to
address any issues that may be identified.
5. IMS Quality Assurance (QA) – The IMS project QA Manager
independently reviews the rated data and works with our
Project Manager and QC team to correct any issues observed.
6. Client QA – The IMS Project Manager reviews the findings of
the pavement condition data with Village staff before
beginning any analysis or reporting activities. IMS will present
the pavement condition data in a Client Review Spreadsheet
(CRS) along with maps illustrating pavement conditions for
the client to independently review.
Rutting and Roughness
IMS’ LCMS-2 systems detect rutting on asphalt roadways using laser
measurements of transverse profiles that are collected continuously
as the vans drive at normal traffic speed. With more than 4,000
measurement points collected per transverse profile and sub-millimeter vertical accuracy, the LCMS-2
can define transverse profiles with a high level of precision, accuracy, and repeatability.
Once all the transverse profiles are collected for a roadway, IMS uses the Brazilian Method, which is an
industry standard method, to determine the rut area and the deepest (or maximum) rut depth for the
profiles. These values, as well as width of rut and color coding, can be seen in the LCMS-2 laser image to
the right. Red represents high severity rutting, while orange represents moderate severity rutting. The
severities are determined based on maximum rut depth thresholds that are specified in ASTM D6433.
Pavement roughness is evaluated by measuring the
accumulated difference in the vertical displacement of a
road surface, independent of chassis response, over a
prescribed road length (longitudinal profile). This
roughness is typically reported via the International
Roughness Index (IRI). IRI data is calculated in real time
from continuous longitudinal profile data collected by
the LCMS-2’s 3D profile device. To determine the road
profile, data is simultaneously obtained from three
devices: a pulse transducer-based distance-measuring
instrument (DMI), high-speed 3D laser sensors operating
at 112 MHz, and an accelerometer in compliance with
ASTM E 950. The LCMS-2 unit conforms to a Class I
profiling device, and it can also “pause” over non-valid
roadway sections such as localized maintenance
activities, railroad crossings, speed bumps, and brick
inlays and not affect the IRI value.

Deflection Testing: Fast Falling Weight Deflectometer
Subsurface distress investigations are a valuable tool to assess the sub-grade condition of a roadway.
IMS will integrate the Structural Index (SI) as a component of each roadway’s final PCI score. In an effort
to provide the best data to our clients, new for 2022, IMS will assess the subgrade strength using our
Fast Falling Weight Deflectometer (Fast FWD). As with previous surveys with the Dynaflect, the Fast
FWD will be utilized for Asphalt and Concrete roadways in accordance with ASTM standards.
Deflection testing is typically completed at least once in each
direction on every street segment (approx. 500 feet) along the
outside lanes of the roadway. Testing shall be altered to an inside
lane when it appears to be in a worse condition than the outside
lane of the segment based on site observations. IMS will record
the readings of a series of geophones for inclusion in the overall
pavement condition rating. These readings will then be used to
determine the pavement strength, load transfer capabilities, and
identify properties of the base and sub-grade.
Upon completion of the deflection survey a structural analysis is performed. Fast FWD’s apply a known
load to the pavement and measure the pavements response to the load. The structural adequacy of a
road is expressed as a 0 to 100 score with several key ranges: roadways with a Structural Index greater
than 75 are deemed to be structurally adequate for the loading and may be treated with lightweight
surface treatments or thin overlays. Those between 50 and 75 typically reflect roads that require
additional pavement thickness; and scores below 50 typically require reconstruction and increased base
and pavement thickness.
The adjacent graph presents a
sample structural adequacy plot of a
recent client’s roadway network
against its average pavement
condition. The diagonal blue line
separates roadways that are
performing above expectations
(above the line), from those that are
not, (below the line). The small
number of roadways falling below
the diagonal line indicates this client
has a low percentage of roadways
that are structurally inadequate for
their design load. Structurally
inadequate roadways are typically
the result of insufficient base and structural materials during the original construction, or the application
of overlays that were too thin during the lifetime of the roadway.

Quality Management
Based on discussions with the Village during the project initiation and kickoff meetings, we will develop
a project-specific version of our Quality Management Plan (QMP) for this project. The plan will address
the following:
• how the data collection equipment will be calibrated and certified
• what data quality control measures will be conducted before data collection begins and
periodically during data collection
• how data will be sampled, reviewed, and checked for quality
• what error resolution procedures will be followed
• how data will be accepted
Prior to data collection beginning, we will submit a customized QMP for approval by the Village.
Calibration and Verification Sites
Prior to the start of data collection, a set of calibration and
verification sites will be selected to cover the range of
pavement types and road conditions present within the Village.
Reference data will be collected including setting the “known
values” or benchmark values for the sites: roughness, rutting,
cracking (alligator, longitudinal, and transverse), potholes, and
patching. The automated survey equipment measurements on
at least five repeat runs will be compared to these benchmarks
to ensure that the resolution, accuracy, and repeatability
requirements in the QMP are met. The calibration process will
be run once before data collection begins, and the verification
process will be run monthly and at the end of data collection.
Data Quality Monitoring
During the collection and processing workflow, data
discrepancies are detected in three ways:
1. During data collection by means of real-time health
monitoring systems onboard the data collection vehicle.
2. During data processing in Connect’s data import module by means of data quality checks which
include data completeness and data synchronization validation, and
3. During data reporting in Connect’s report generation module by means of sensibility and range
checks.
These processes are run on 100% of the collected and processed data. Any road sections with data
discrepancies arising from sensors, systems, or processing that exceed the defined thresholds will be
recollected and/or reprocessed, as necessary.
Image Sample Checking and Distance/Location Verification
Connect™ will facilitate the quality control process by allowing for a review of a random sample of
pavement images to confirm the accuracy of reported distress data. The detailed distress data for each
image, including both cracking and the classified and rated distresses, are shown superimposed on the
pavement image. They are also shown in a table. This allows a user to efficiently review and confirm that
the condition of the road has been surveyed accurately.

Our Connect™ software also shows the vehicle GPS traces (collection polylines) overlaid on a street view
map or an aerial image. They are shown together with the GIS shapefile polylines provided by the
Village, so that it can quickly be verified that the correct sections were driven, that section limits are
correctly identified, and that the vehicle GPS is accurate. This all-in-one processing software makes
location errors and misplaced sections things of the past, and the transparency improves client
confidence in the delivered data.

Semi-Automated QC/QA
IMS has developed a unique approach to pavement condition assessments by coupling manual review of
distress data with automated algorithms. This more rigorous QC/QA process ensures that the
automated distress detection and classification algorithms that we use work correctly. Our Pavement
Engineering team fully understands the capabilities and limitations of the state-of-the-art LCMS-2
technologies and sophisticated algorithms that we employ, and our QC/QA steps are extremely
important in ensuring the success of the project.
The IMS QC/QA process is comprehensive and makes use of field observations, automated data
processing tools, manual data review by our QC team, independent review by our QA manager, and
lastly, final review by the Village. There are QC/QA checks at each stage of the project to ensure data
quality before the data is moved into the next steps.
Machine learning and artificial intelligence have made leaps and bounds in speeding up distress
identification. And when supplemented with trained pavement raters, field staff, and expert engineers,
they establish high data confidence and integrity. The final quality assurance performed by Village
personnel will ensure that the Village has confidence in and takes ownership of the condition data.
ESA: Pavement Management Spreadsheet Update
ESA will be updated to develop a multi-year maintenance and
rehabilitation plan using “cost of deferral” as a rehabilitation candidate
selection constraint to introduce cost-benefit techniques into the Village’s
Pavement Management Plan. In addition, IMS will be able to update the
deterioration curves for each functional classification, pavement type, and even pavement strength
rating. Storing the data in this open architecture empowers the Village to utilize third-party software in
the future if desired. ESA will also contain a full suite of maintenance and rehabilitation techniques, unit
rates, and associated PCI resets. The parameters of the analysis (Priority Weighting Factors) can also be
modified and reprioritized whenever required. This flexibility will allow the data to evolve with the
priorities of elected officials and department staff. Programmed Priority Weighting Factors include
functional class, pavement type, and strength, while candidate selection is based on the incremental
cost of deferral.

M&R Program Development and 5-Year Analysis
Once the QC/QA process has been completed, our
project team can build the Village’s multi-year
pavement management plan. Our multi-year pavement
M&R programs are built around practical prioritization
techniques and financial optimization, typically in the
form of cost of deferral. IMS incorporates pavement
management principles that assist agencies in
producing cost effective maintenance programs.
Localized construction costs, customized deterioration
models that reflect local pavement performance, and
other environmental and local construction practices
are considered in developing our M&R analyses and
recommendations.
Our approach to establishing overall prioritization of
M&R recommendations is flexible and can account for non-engineering factors. Our engineering team
has recent experience using pavement management systems to develop equitable M&R plans that
consider funding distribution based on technical and non-technical considerations that impact local
communities. We look forward to collaborating with the Village staff to ensure that the pavement
management program addresses the needs and priorities of the stakeholders involved.
Pavement Management Report
The following list highlights the key components in the analysis and hard copy final report.
• Executive summary – The Summary will include an overview of the 5-year maintenance and
rehabilitation schedule that is more thoroughly reviewed in the full Report.
• Principles of pavement management – Detailed look into how network quality and backlog are
evaluated, review of pavement preservation methods, and the economic impacts of
maintenance and rehabilitation.
• Road ownership and inventory and attribute report
• Present condition ranking – detailed and summary condition data including Good/Fair/Poor,
Load Associated Distresses (LAD), Non-LAD, Structural condition (if deflection testing is added)
and Project reviews of each road in the network, as well as the entire network.
• “Fix all” budget analysis – this identifies the upper limit of spending by rehabilitating all roads
assuming unlimited funding.
• “Do nothing” analysis – this assesses the impact of not performing any roadway rehabilitation.
• Steady state rehabilitation life cycle analysis – this identifies the minimum amount of
rehabilitation needed to maintain the existing level of service over 3, 5, or 10 years.
• Integration of capital projects and master plans – ongoing and proposed projects that affect
roadway rehabilitation planning will be incorporated into the analysis.
• Five-year rehabilitation and prioritized paving plans – based on need, available budget and level
of service constraints; a minimum of seven budget runs will be completed.
• GIS-based Maps – the IMS GIS team will produce various maps for the report including 5-year
plans (year and rehab type), class, need year, budget scenarios, PCI, etc.
• Summary review of past data – including previous surveys, past PMS reports, and impacts of
previous M&R.

Proposed Project Budget
The detailed budget presented below represents the services covered herein and is a realistic budget to
complete the work. The budget is based on a Spring of 2023 mobilization in conjunction with IMS’
planned work in Chicagoland. In appreciation of this flexibility with the schedule, IMS has offered a
reduced mobilization fee in the budget. We are confident we can maintain an on-time, on-budget
approach to the assignment.
Note:
IMS has included a contingency in this proposal in case the need arises for traffic control as a function of
the deflection surveys. These funds will not be required if the Village provides a shadow vehicle on
major roadways as requested by the crew. Traffic control is typically not required for residential roads.
