1.1 EXECUTIVE SUMMARY
Since 1985, IMS Infrastructure Management Services (IMS) has operated as
the premier pavement and right-of-way (ROW) asset management firm in
the United States. IMS is a dedicated pavement management consulting
firm that operates a fleet of advanced mobile data collection vehicles
equipped with millimeter level scanning devices called the Laser Crack
Measurement System (LCMS). Our team completes over 100 pavement
and asset management implementations across North America annually,
and we stand second to none in our ability to establish cost-effective
maintenance management programs for large and small agencies alike.
While IMS has a large national footprint, we also have a local mindset
resulting from pavement management assignments with Sandpoint and
Pocatello, ID; Riverton, Casper, Sheridan, and Lander, WY; Lynnwood,
Bellevue, Bainbridge Island, Mercer Island, Federal Way, Bellingham, Port
Orchard, Edmonds, Bremerton, SeaTac, Tacoma, Yakima County, Auburn,
Pacific, WA and many more throughout the Northwest. Additionally, IMS
has recently been awarded the automated pavement condition surveys for
the City of Pasco and Mill Creek, WA.
As a result of our experience across the United States, the IMS team has an
unparalleled understanding of mountain roadway conditions, ASTM D6433-
18 protocols, software configuration, enhanced customized prioritization
techniques, and the City's desire to develop a world-class pavement
management program. The data can then be harnessed to develop
comprehensive multi-year street rehabilitation plans that optimize
pavement quality and minimize annual expenditures.
The IMS team will ensure the PAVER deliverable provided to the City
maximizes available resources by utilizing defensible and objective pavement
performance data that has been designed around the ASTM D6433-18 data
collection protocols that satisfies the City’s expectations. IMS is a leader in
the field of automated pavement condition assessments and has the PAVER
expertise necessary to ensure the condition data delivered to the City of
Bozeman meets the intended scope of services listed in the RFP. IMS Project
Principal and VP of Engineering, Dr. Kurt Keifer, P.E., PhD, assisted with the
development of the PAVER software application in 1997 and has spent the
majority of his career fine tuning his PAVER experience.

2.0 PROJECT OVERVIEW

3.1 PROJECT APPROACH AND METHODOLOGY
The IMS team will work directly with the City's Project Manager to confirm the final scope of services,
deliverable expectations, schedule, and the overall milestones for this project. IMS works with each client on
a one-to-one basis, as we understand each City has unique goals and objectives related to the implementation
of a comprehensive PMP. Our team approach to project management will ensure that the City of Bozeman
not only acquires quality ASTM D6433-18 condition data, but it also retains a long-term consultant that can
adapt to the City's evolving needs. IMS project innovations summary:
•Objective laser-based cracking, rutting, roughness, bleeding, pothole and geometric surveys.
•Up to four views of high-definition (4112 x 3008) digital imagery linked to the City's GIS.
•Flexible industry standard data outputs (Excel, Access, shape files, geodatabase, KML/KMZ).
•Optional analysis techniques can provide City staff with defensible rehabilitation recommendations.
Automated Pavement Distress Survey – The Laser RST equipped with the LCMS2 technology is the most
sophisticated technology available and will result in an objective ASTM D6433 survey that maintains the
continuity of the legacy data collection protocols. The LCMS2 is a high-speed laser scanning device with a
1-millimeter resolution, meaning it deploys a continuous scan of laser points (approximately 3,992) across
a mere 13 feet of pavement. The onboard processing software then amplifies its capabilities by analyzing
pavement elevation (range and intensity) and automatically identifying cracking, rutting, roughness in the form
of IRI, potholes, and bleeding.
Street Network Inventory & GIS Integration – The City of Bozeman street network consists of approximately
242 centerline miles of paved streets. IMS will perform a linear pavement distress survey on 100% of the paved
roadway network length. IMS will survey all City roadways in a single pass, resulting in 242 survey miles. IMS
is proposing a single pass test because it is the minimum survey mileage required to maintain an effective
and comprehensive survey, while keeping a lower cost of data collection. If preferred by the City of Bozeman,
IMS is ready and able to perform a double-pass test on arterial and/or collector roadways. While the LCMS2
RST will validate roadways’ lengths in the field, IMS also validates all segment lengths and widths using aerial
photography prior to the field data collection.
IMS will begin the project by adopting the City’s existing pavement database and GIS in an effort to prepare the
survey inventory for field data collection. New roads will be added and the City’s pavement inventory will be
reviewed to ensure it meets pavement management requirements. The IMS surveys are tightly coupled with
the City’s existing GIS environment resulting in a seamless transition of data that is linked to a unique identifier
in the City’s GIS.
HD Imagery – IMS can utilize up to four GPS-referenced
HD camera views (4112 x 3008) for our QA/QC program,
optional ROW asset inventory development, virtual drives,
and/or other supplemental image deliverables. For the
City of Bozeman, IMS will utilize at least two HD cameras
that will be proofed out prior to data collection. IMS uses
a minimum of two camera angles for our internal QA/QC
process. If added to the scope, the City can have imagery as
3.0 PROJECT APPROACH
5
a deliverable at the conclusion of the project. As an optional service, images can be delivered via a hyperlinked
shapefile and hard drive. IMS also has a web-hosted data viewer for virtual drives.
GIS Integration – The key to the success of any pavement management program is the ability to spatially link
all data collected by the IMS team to the City’s existing GIS environment. The Laser RST utilizes onboard GPS
and inertial navigation to achieve sub meter location accuracy that allows all IMS outputs to be linked to GIS
and the PAVER/Cityworks applications. Thus, potential integration with legacy applications is seamless when
the data is spatially linked.
Data Processing, Formatting, and City Review – Prior to the PAVER and Cityworks data loading activities, the
condition data will be delivered to City staff into a navigable spreadsheet, complete with graphs and descriptive
terms such as Good/Fair/Poor. The detailed PCI extent and severity distress data is also aggregated into an easy
to understand 0-10 index to assist in City review. The condition data is delivered as a geodatabase, a series of
shape files, and KML/KMZ files to ensure City staff comfort with the data outputs prior to PAVER and Cityworks
integration and loading.
PAVER Data Load, Configuration; Cityworks Link – After review of the draft condition results with City staff, IMS
will batch import the pavement inspection data (distress extent & severity) into the PAVER application for each
management section. In addition, IMS will review the major and local rehabilitation activities and unit rates
with City staff to ensure proper setup and assignment. Critical PCI point selection will be made within PAVER to
ensure proper configuration of the system based upon the City’s PCI distribution curve. IMS can then provide
a mapping utility link from the PAVER data to Cityworks (if desired).
Multi-Year Pavement Management Report – With the analysis complete and approved by City staff, IMS
will aggregate the information into a bound report that reviews the concepts of pavement management, PCI
calculations, condition results, network value, operating parameters of the analysis, budget scenarios, and
5-year pavement management reports. The analysis and report will go through several iterations of review
before being finalized and presented to City staff.
Optional Enhanced PAVER Analysis – While the detailed pavement condition data will be loaded to PAVER for
delivery to the City, IMS can enhance upon the typical PAVER analysis through the integration of roughness in
the form of IRI, structural integrity (using deflection data or the presence of load associated distresses), and
project development ranging from an On-street approach to a neighborhood plan based on geography.
The IMS enhanced PAVER approach allows for rehabilitation candidate selection to be based on user defined
priority weighting factors (functional class, pavement type, strength, & districts), optimization in the form of a
“cost of deferral” analysis, and use of a full suite of rehabilitation activities ranging from various types of surface
treatments (slurry, micro, chip, cape, etc.). Candidate selection will also be based on various thicknesses of
overlays (including ancillary costs such as milling, peripheral concrete, structural patching, etc.), and deep
patch and pave programs that attempt to minimize expenditures by delaying the inevitable total reconstruction.
The end result of an IMS enhanced analysis is a comprehensive 5-year rehabilitation plan that accommodates
for the limitations of the PAVER pavement analysis. The final results and projects can be easily loaded back into
PAVER for completion. Alternatively, IMS can complete the entire pavement analysis within PAVER, however,
the many enhancements discussed above (i.e. IRI, structural integrity, cost of deferral, and rehabilitation
flexibility) are not available within the application.

3.2 OBJECTIVE ASTM D6433-18 DISTRESS ASSESSMENT
The IMS fleet of pavement performance equipment includes seven Laser
Road Surface Testers, four of which are outfitted with the LCMS2 technology.
IMS also has access to two Dynaflect Devices and four Sidewalk Surface
Testers. For this survey, we propose to use an LCMS2 – enhanced Road
Surface Tester (RST) coupled with HD digital imagery and GPS capabilities.
The LCMS2 based RST, with its 2-sensor array is capable of collecting a full
suite of ASTM compliant pavement condition data complete with high
accuracy GPS coordinates and multiple view HD digital images for both rigid
and flexible pavements (in real time). The LCMS2 equpment provides three
demensional high-speed, millimeter-level scanning and pattern recognition
analysis. Specialized data processing, using GIS as its backbone, allows the
pavement data to be quickly checked for completeness and quality.
The Laser Crack Measuring System 2 (LCMS2) also automatically collects
transverse cracking, block cracking, alligator cracking, longitudinal
cracking, rutting, potholes, faulting, roughness, geometrics, and texture.
The LCMS2 technology automatically detects cracks and minute variances
in the pavement surface using a horizontal resolution of 1mm. Thus,
the LCMS2 greatly diminishes the subjective nature of PCI data collection
performed by image-based surveys or even point lasers.
IMS conducts a modified ASTM D6433-18 inspection whereby we capture
10 asphalt and 10 concrete distresses by extent and severity. In an effort
to capture more information on the pavement, IMS also collects extent
and severity data on a single asphalt distress called "Distortions", which
represents all bumps, sags, heaves, corrugations, depressions, and swells.
MAIN COMPONENTS OF AN
AUTOMATED ASSESSMENT
A 2-sensor, 3D LCMS2 array coupled
with 2 IMU’s (inertial measurement
unit) are utilized to measure pavement
roughness, rutting, cracking, potholes,
bleeding, geometrics, and many other
common ASTM D6433-18 surface
distresses.—
Automated crack profiling and
production of extent-severity based
pavement distresses through the 3D
crack profile software.—
Up to 4 HD digital cameras are
mounted for forward, side, rear, and
right-of-way views.—
Ability to collect dual wheel path
roughness to International Roughness
Index (IRI) standards using 3D profile
technology.—
High accuracy Global Positioning
System (GPS) receiver with OXTS
inertial navigation for geo-locating of
pavement and asset information with
excellent accuracy.—
Dual distance measuring instruments
to measure linear distances to within
+/- 0.5%.—
Built-in software and on-board
processors to develop roadway
inventories, time code integration,
and system monitors. —
Integrated touchscreen event board
used for capturing additional roadway
attributes on the fly or to expand the
roadway distress data to be captured.
The touchscreen is programmed
with a mobile mapping device to
ensure navigation and routing is as
efficient as possible. All inputs can be
programmed for acquisition using a
standard extent and severity format.

3.3 OBJECTIVE DISTRESS IDENTIFICATION AND QUANTIFICATION
The IMS Laser Crack Measurement System 2 (LCMS2) is one of the most technologically advanced devices
available for pavement performance assessments. The 2-sensor array completes a 3D millimeter-level scanning
of the pavement surfaces that pass below the laser array. With a high-speed 1-millimeter resolution, this
means the LCMS2 device deploys a continuous scan of laser points (approximately 3,992) across a mere 13
feet of pavement, making it one of the highest resolution pavement laser scanners available. The onboard
processing software further amplifies its capabilities by analyzing pavement elevation (range and intensity) and
automatically identifying cracking, rutting, roughness in the form of IRI, potholes, and bleeding.
While any engineering firm could deploy the LCMS2
equipment for data collection, processing the
information for distress quantification requires a
complete understanding of automated technologies,
GIS mapping, and distress measurement protocols
found in standards such as ASTM D6433-18. Simply
reviewing the LCMS2 cracking vectors (colored cracks)
with the human eye dilutes the objectivity of the
equipment.
IMS engineers and technologists have developed a
computerized processing application that automatically
applies an 18”x18” grid to the LCMS2 downward
images (FIS files) and uses pre-programmed geometric
algorithms to classify and quantity distresses by type.
These automated processing routines result in an unparalleled level of objectivity and efficiency in distress
pattern recognition analysis. The image above illustrates the quantity of several distresses as well as the
presence of a manhole, which was automatically scrubbed
from the dataset.
In addition to the auto-quantification and classification
of ASTM D6433-18 distresses, the LCMS2 device also
operates as a Class I profile device that collects longitudinal
profile (in the form of the International Roughness Index)
and transverse profile (rutting) using advanced 3D profile
laser scanning technology. The system is not subject to
vehicle wander like other automated technologies, and it
compensates for variation in driver ability. The adjacent
images show the processing software’s ability to calculate
rutting width and depth following the AASHTO Taut Wire
methodology. The solid white lines indicate there was
no rutting in the left wheel path and that rutting was
detected and measured in the right wheel path. Filters
can also be applied to account for rehabilitation activity
overlap, which can be as much as a ¼ inch depending on
the application.
8
3.4 GIS INTEGRATION AND MAPPING
The role of GIS in pavement management
cannot be overstated. It is a powerful tool
that provides the ability to handle vast
amounts of data in an efficient manner.
Not only does GIS allow an agency
to visually plot textural data, it also
establishes an easy access portal to the
data through an efficient integration with
many third party pavement management
applications.
IMS will kick off this project by completing
a review of the City's GIS environment to
assess suitability for network referencing,
survey map preparation, PAVER +
Cityworks integration, and pavement
management purposes. Our team will consume the City's existing GIS centerline files. IMS projects that the City
has a quality GIS database, based on previous projects, and the existing segment limits will be maintained (0.1
mile increments or intersection-to-intersection). IMS can also develop logical projects or SuperSegments based
on condition.
The data collected by IMS is linked to the existing GIS environment and is supplied as a personal geodatabase,
spatial database engine, AutoCAD files, or a series of shape files. IMS collects XY coordinates for all data elements
using GPS technology coupled with inertial navigation and integrates with most third-party GIS applications,
including ESRI.
At a minimum, the GIS supplied by the City should have an ownership attribute, PAVER IDs, FacilitysID’s,
functional classifications, contiguous line work, and be in a digital format such as shape files and/or personal/
file geodatabases. As a supplemental task, IMS also offers full-service “GIS Clean-Up” and “Functional Class
Review” activities for agencies that require additional GIS development above and beyond standard network-
referencing activities.
For this assignment, GIS will be used in four key areas of work:
1.GIS will be used to verify the streets to be surveyed and to create the routing maps for use during the field
surveys.
2.The survey productivity will be tracked through the plotting of the GPS data collected during the field surveys.
This will allow IMS to review all streets that have been covered, identify anomalies in the referencing, and
spot missed streets.
3.GIS will be used in processing the distress and inventory data. By plotting the data, we can QA the data and
identify data exceptions in addition to proofing out the GIS.
4.Personal geodatabases, spatial database engines, shape and/or KML/KMZ files can be created for the visual
presentation of condition data and analysis results.
9
3.5 CAMERAS AND EQUIPMENT CONFIGURATION
The IMS RST can mount up to four HD
cameras on the platform, depending
on the required views or roadside
assets to be inventoried. Prior to
commencing the field surveys, our
team will confirm the pavement and/
or right-of-way views for collection.
As an example of pavement image
quality, the image to the right
illustrates the pavement view from
the LCMS2 RST during a recent
assignment. The adjacent image is
from a recent survey of Sandpoint, ID
from late September to early October, 2019.
Based on our understanding of this assignment, IMS proposes a configuration of two HD video cameras for
our internal Quality Assurance purposes. The camera views will be proofed out at the calibration stage, as
it may be desirable to relocate or change the orientation of a camera. If requested, these images linked to
the City's existing GIS centerline and provided as a geodatabase with
image hyperlinks. The HD imagery is processed and collected in 15-foot
intervals. While IMS collects 4K imagery, most agencies do not have
access to 4K monitors and thus we compress the imagery to alleviate
any storage challenges the City may have.
For this project, IMS will be utilizing AVT Manta G-1236 B/C GigE high-
resolution cameras. With these cameras deployed, City staff can rest
assured that the image quality will be state-of-the-art, directly integrated
into the RST’s DMI unit. The AVT Manta cameras are capable of capturing images at 4112 x 3008 resolution
and up to 125 frames per second.
The image below illustrates the proposed camera configuration for this project:
•Camera 1 – Left Front: View offers a forward-facing view that is angled toward
the centerline of the roadway with the right side of the camera view overlapping
with Camera 2 for full coverage.
•Camera 2 – Right Front: This angle is used for 180-degree forward view and for
right-of-way asset data extraction. Camera is oriented to capture most signs and
not too much horizon. The left side of the camera view is calibrated to overlap
with Camera 1 for full coverage.
•Camera 3 – Right Rear: View is oriented to capture a downward pavement view
used in the IMS QA/QC process and final engineering review.
•Camera 4 – Left Rear: View is oriented to collect reverse-facing signs, markings
images, sidewalks, and many other assets on the adjacent side of the roadway.
10
3.6 QUALITY ASSURANCE AND CONTROL
Each step in the IMS data collection
process has been designed to require
the data to pass a certain standard
or validation before moving on to
the next stage. If the data does not
pass, it is returned to the source for
correction. LCMS2 is a Class I profile
device that allows for the auto-quantification and classification of most ASTM
D6433 distresses. The system is not subject to vehicle wander like other
automated technologies, and it compensates for variation in driver ability
through the automated detection of pavement edge, curb/gutter, and
centerline striping.
In conjunction with the IMS Employee Policy Manual, all field operators are
required to implement the following field safety procedures when operating
the RST survey vehicle.
•All IMS RST vehicles must be fitted with seat belts, safety lights (flashing
and/or strobe), vertical guide sticks on the front bar, “Caution” sign
placard, and fire extinguisher.
•Daily RST “circle checks” are to be conducted to ensure equipment
maintenance.
•RST is to travel at or near posted speed limits (over 15 mph) so as not to
impede traffic and the survey is conducted in the curb or shoulder lane.
Lane changes are only made when absolutely necessary.
•Avoid collecting data during high peak times on heavily traveled
roadways.
•Cease survey operations during rain/snow/cold (less than 32°F) or other
poor weather conditions.
Quality Control and Quality Assurance Program
The strength of the LCMS2 platform is best demonstrated by its ability to collect
and verify a wide array of digital images, GPS coordinates, and pavement
distresses in a single pass. Through the integration of a LCMS2 laser array and
the GPS system – the data collection vehicle can collect the required data
elements continuously while also performing quality assurance on the fly.
At the start of the survey:
•A Project Information Form (PIF) will be created that details the survey
scope and data to be collected. The project protocols will be documented
and approved.
•The PIF will be compared against the RST set up and the data collection
protocols.
•Equipment is calibrated.
•Field crew meets with the client to review the maps and overall project.
QC PLAN SUMMARY
Inventory Preparation – a coverage
map is prepared for review to ensure
all roadways desired for survey are
captured. This map is eventually loaded
into the RST for survey.
Data Collection – the equipment is
calibrated on a daily basis and it is
also paused over “events” that would
cause erroneous data to be collected
(i.e. railroad tracks, speed humps,
valley gutters, etc.). A field survey daily
report is also sent to the Crew Chief and
reviewed by a Senior Technologist for
approval.
Processing Filters – processing tools
are extensive and allow for erroneous
data (i.e. manholes, curb lines, tool
marks, rehab activity overlap, striping,
macrotexture for intended rehab
designs, etc.) to be filtered out of the
data stream.
LCMS2 Image Review – all 16-foot
LCMS2 image and cracking vectors
are reviewed by a qualified inspector
in the office to ensure there are no
discrepancies in the data stream or the
auto-classification and quantification of
distress densities.
Project Manager Review – before any
data enters the analysis phase, the
assigned Project Manager, Dave Bratton,
reviews the forward HD imagery
collected in the field and compares
it to the processed PCI Data. If it does
not pass the QC tolerance test, it is sent
back for further processing.
11
On a daily basis:
•Equipment is calibrated and daily reports completed.
•All sensors are continually monitored to ensure they are receiving data in specification.
•The LCMS2 Crew Chief and operator also manually monitors the digital image, GPS, distress recorder and rut
data.
•Production is tracked and records of coverage are taken. Each street is noted on the inventory and map, as well
as through GPS and assignment of the LCMS2 van number.
•A select roadway section (control) is re-surveyed to ensure image quality and repeatability.
•A precision verification plan and corrective action plan is followed as necessary.
•All data is backed up and sent for processing.
At the end of the survey:
•Field crew meets with the client again to review the maps and overall project.
•Data production and coverage is reviewed to ensure all streets have been captured.
•Calibration and adjustments if a 30% difference is noted.
After data collection:
•The data is scrubbed and processed for anomaly reduction.
•The data is verified by the Project Manager, Dave Bratton.
•Bi-weekly reports with the City of Bozeman project manager.
•The detailed section level data is aggregated into the approved segmentation for client review.
•The final deliverable format is populated and undergoes a QA process performed by the Project Principal.
Quality Control Routines
IMS has developed a QA/QC management program that is suited for our LCMS2 technology and internal data
management procedures. The IMS crew will also complete our daily QC routines for the LCMS2 van.
•Calibrations & Demo: All digital camera, GPS, DMI units, LCMS2 laser arrays and switch-input keys are
calibrated prior to data collection, and then daily during the project.
•Daily Survey Control: Each day, selected roadway sections will be re-tested to confirm repeatability of the
data. Camera and video quality assurance checks are performed.
•Validations: Range limits and data validation routines are integrated in the on-board processors and
post processing routines. Validation checking routines monitor “out of range” data, extraneous data, and
missing data.
•Inventory & GIS Review: All data is plotted and compared to Bozeman's GIS. This will identify new roads,
missed roads, duplicates and non-City roads.
•Length Reviews: All section lengths are compared against published values to identify survey under/over
runs.
•Test of Reasonableness: Process and compare LCMS2 data and digital image data at specified reporting
interval. Compare individual distress and overall condition ratings. Identify non-compatible data locations
and reprocess accordingly. Site visits to select sections will also be part of the test of reasonableness.

3.7 IMS OPTIONAL PAVER ANALYSIS
Immediately following the completion of the field surveys, IMS can begin processing the ASTM D6433 pavement
distress severity and extent scores in an effort to develop a data import file that can be loaded into PAVER and
an autolink to Cityworks can be provided. With the inspection data loaded into PAVER, a Pavement Condition
Index (PCI) for each roadway segment or management section can be calculated. The purpose of this section
is to explain the functionality and constraints of the PAVER analysis.
Family Models
The PAVER software relies on the concept of “Families” for most of its modeling. A “family” is simply a set of
pavements that share a group of characteristics. This can be a surface type, a functional class, traffic patterns,
location within the City, unit rates, construction techniques, or any other factor that would cause a pavement
to deteriorate similarly or share costs. As a part of the optional analysis, IMS could review the family models to
ensure they are adequate for pavement management purposes.
Key Set Points and Pavement Performance Curves
The PAVER program requires user inputs in order to complete its condition forecasting and prioritization. A
series of operating parameters can be developed in order to create an efficient program that is tailored to the
City’s needs as follows:
•Pavement performance curves that are used to
predict future pavement condition. PAVER allows
for historical data to be used to build deterioration
models that reflect actual pavement condition
over time. This gives an agency the ability to
group streets into families that share similar
characteristics that play a part in deterioration.
Examples include functional class, pavement
type, AADT, soil properties, heavy vehicle traffic,
test pavement and construction method. As a
substitute, IMS can develop curves based on
data from decades of surface surveys which the
City can use until sufficient data is available to build custom curves.
•Having a threshold for Critical PCI. PAVER allows the user to pick a point where rehabilitation is most
necessary. Generally this point coincides with either a greater cost of rehabilitation or an increase in the PCI
deterioration slope.
•Priority ranking analysis in PAVER uses prioritization for rehabilitation candidate selection based on a
segments Use and Rank. In the program “Use” defines the role the pavement plays (Roadway, Parking Lot,
Driveway), while “Rank” defines its functional class. Since this project only focuses on roadways (except for
the optional bikeway assessment) the prioritization will be entirely based on Rank. Commonly higher traffic
the functional classes receive a higher priority. This ensures that streets that service the most residents
undergo rehabilitation first to provide as much benefit per person as possible. For the majority of agencies,
this places Arterial and Collector segments at a higher priority than Local streets.
13
Rehabilitation Strategies and Unit Rates
One of the goals of any pavement management project is to develop a system that
allows the City to rehabilitate pavements at all points in its life cycle. The main
purpose is to extend the useful life of pavement for minimal cost, thus adhering
to the principles of pavement preservation. In order to do this, an agency must
adopt strategies that address pavement distress at its earliest point in order to
preserve the pavement. The most common way to do this is to seal the pavement
or repair load associated distresses. For many agencies, current rehabilitation
strategies can often be reactive to already deteriorated pavements with a focus
on heavy overlays and reconstructs. To enhance upon the critical needs of an
agency, the PAVER system can incorporate localized and global strategies such as
crack sealing, patching, slurry seals, and micro-surfacing.
CITY OF BOZEMAN FINAL DELIVERABLES
Once the analysis is complete and data loaded into the City's PAVER database, City
staff will recieve the two requested deliverables to complete the project.
Deliverable 1 - City staff will be provided with three hard copies and one PDF
electronic versuon of the final written report. The details of the report are found
in the sidebar of this page. The report will include a comparison of the 2020
pavement condition results against the 2013 survey findings. This will include an
evaluation of the effectiveness of the City's current street maintenance program
and recommendations for future street maintenance.
Deliverable 2 - IMS will coordinate with the City's GIS department to integrate all
collected data into both the City's PAVER and Cityworks databases.

6.1 PROJECT PROFILES AND REGIONAL EXPERIENCE
The Northwest Unites States is home to a long list of IMS
clients. Our projects take us to all corners of the United
States and Canada, from Key West, Florida to Vancouver,
British Columbia. IMS performs more than 100 pavement
management projects annually and on all assignments,
the IMS team utilized our LCMS2 Road Surface Tester
(RST) to perform a network-wide pavement performance
evaluation. While some firms perform sampling based or
windshield surveys on a select portion of the network, IMS
surveys 100% of the roadway length in a linear manner.
Our philosophy is based on the provision of quality
pavement condition data for the implementation of
comprehensive multiyear pavement management plans.
IMS serves as the dedicated pavement and asset management firm for municipalities large (Atlanta, GA) and
small (Del Mar, CA). As a firm dedicated to pavement management, the City of Bozeman can rest assured that
the end-users will receive quality pavement condition data for the development of the long-term and defensible
rehabilitation programs. Presented below are a few projects illustrating IMS’ capabilities to implement and update
comprehensive pavement management systems.
City of Spokane Valley, WA: Originally awarded in 2011 and for four projects over 8 years, IMS was selected to
perform an automated pavement condition assessment using the RST on 230 test miles of roadway. The data
was collected and originally loaded into the City’s Cartegraph application. All data was linked to the City’s GIS and
delivered as a personal geodatabase. A comprehensive roadway network analysis and final report was delivered as
well. IMS and the City teamed up every two years to perform a network condition update with a new pavement
analysis and report. Subsequent surveys used the IMS ESA spreadsheet.
City of Bainbridge Island, WA: In 2014 and again in 2019, through a competitive solicitation, IMS was contracted
to perform a pavement condition survey on 140 test miles of roadway. In addition to the collection of pavement
condition data, IMS intended to load the data into MicroPAVER but the City was quite pleased with the Easy Street
Analysis spreadsheet (ESA) and GIS linkage. Since our ASTM D-6433 data collection accommodates both the
transition was seamless. A comprehensive roadway network analysis and final report was delivered as well as a
5-year forecast, modeled after the city’s existing projections with maps. In 2019, IMS performed a new survey and
provided the City with updated deliverables.

CITY OF FEDERAL WAY, WA In 2011, IMS contracted with the City
of Federal Way to perform a pavement condition assessment on 285 miles
of roadway. The data was delivered in a similar format as presented by the
previous firm, MRC, on previous assignments. All data was collected with
the ASTM D6433 standard data collection protocols, with all data linked to
the GIS infrastructure. The pavement analysis was completed with the Easy
Street Analysis spreadsheet (ESA) to allow for analysis flexibility. IMS has been
selected every 2 years to perform a detailed assessment of the current PCI of
the city’s streets. IMS delivered an updated report with new budget scenarios,
unit rates, and suggested maintenance and rehabilitation plans.

CITY OF CASPER, WY Originally awarded in 2005 and again in 2018,
IMS was selected to perform an automated pavement condition assessment
using the RST on 345 test miles of roadway. The 2005 data was collected and
originally loaded into the City’s PavePRO application, but the 2018 project
included an update to the IMS Easy Street Analysis (ESA) Spreadsheet. IMS
staff included training acitivities so that City staff would be comfortable with
the ESA spreadsheet. The 2018 survey also included delivery of HD imagery.
During post processing, IMS utilized the HD imagery to log presence of curb
and gutter throughout the City's paved network.

CITY OF POCATELLO, ID Originally awarded in 2015 and again for
a 2019/20 survey, IMS was contracted to perform a pavement condition
survey on 313 miles of roadway. IMS performed a two pass test on the City's
arterial and collector roadways to ensure adequate coverage of the network.
A personal geodatabase, corresponding KML Google Earth file and associated
Maps reflecting the current condition of the City’s roadway network was also
delivered. IMS loaded the collected data into the City's Lucity database.

CITY OF SANDPOINT, ID Awarded in 2019, IMS utilized the Laser RST
to survey approximately 72 miles of City roadways. The pavement condition
data was processed and loaded into the City’s Easy Street Analysis Spreadsheet
(ESA). IMS utilized ASTM D6433 data collection protocols. All of the data
was loaded to the City’s GIS application as well. The end deliverable was a
comprehensive report and analysis detailing the 5-year plan and multiple
budget scenarios. IMS also performed a sub-surface analysis with a Dynaflect
device on 28 miles of arterial and collector roadways. IMS incorporated the
sub-grade analysis into the City's final PCI score.

LARIMER COUNTY, CO Originally awarded in 2016, IMS was selected
to perform a pavement condition survey on the County’s local roadways as
a part of an inspection data pilot program. The project was successful, and
in 2017 IMS was selected through a competitive proposal process whereby
we were contracted to survey all County roadways, including the mainline
routes. The County had traditionally performed in-house MicroPAVER
sampling surveys and the Laser RST ASTM D6433 surveys proved objective,
repeatable, and efficient. Another round of data collection took place in the
summer of 2018, and currently in 2020 as well.

CITY OF LONG BEACH, CA IMS was awarded the pavement
management program update for the City of Long Beach in 2013 and again
in 2017. The project consisted of pavement condition surveys for over 900
test miles that included digital images and deflection testing on the arterial
roadways. In addition, we completed a software conversion from PAVER
to Lucity, as the city desired a more robust analysis tool for managing its
pavements. The IMS engineers the developed individual pavement analysis
studies and reported on the results for the city’s nine districts. The results
and final report were recently delivered to the city. In 2017, the city expanded
the scope to include their Alley network as well.

Currently, IMS has the survey capacity for approximately 2,500 miles/month, so completing the Bozeman surveys
in a timely fashion will not be a challenge. Field surveys are expected to progress at a rate of 30 to 40 miles per day
and are expected to proceed at 5 to 6 days per week, depending on weather and statutory holidays. Elapsed time
for the City of Bozeman field surveys is estimated at 2 weeks. IMS has the available staff, equipment, and resources
to manage a timely project for the City of Bozeman. We have 48 employees, each dedicated to completing more
than 100 pavement management assignments annually.
IMS Workload - During a typical year, IMS routinely sureveys 100-110 assignments. Due to the COVID-19 pandemic
we are on pace to complete around 90-95. IMS has the necessary staff and resources to perform this work if
selected by the City of Bozeman.
In general, it is not the time spent conducting surveys but rather the time spent handling the data that can derail
project schedules. On all projects, three rate-determining functions are most critical in maintaining the proposed
project schedule:
1.Finalizing the inventory and maps to be used for the field surveys – The potential for delay in this step stems
from unexpected issues encountered while obtaining the maps or GIS topology, confirming the streets list, and
then validating the limits of the surveys. To mitigate such issues and proceed with the survey on time, IMS will
confirm the available resources with the City during the project kickoff meeting.
2.Reviewing the field data and exceptions reports delivered to the City – As part of the QA/QC process, only
quality data can pass through to the analysis. Thus, it is critical that once the data passes through the IMS QA/
QC process, it is accepted and signed off by the City.
3.Obtaining feedback and acceptance of the final format and load – No matter how much planning work goes
into a schedule, the bottom line is that the project must be able to conform to the City's schedule.
The below schedule assumes snow coverage of the area holds off until after Data collection occurs in November. If
the weather does not allow that to happen, IMS will aim for a project completion date of early June, 2020.
