2024 City Of Round Rock Pavement Survey
SERVICES TO BE PROVIDED BY THE CONSULTANT
GENERAL PROJECT OVERVIEW
For the scope of services for this contract the Consultant shall provide professional
services for conducting pavement condition surveys on the entire roadway network and
implement pavement management software. Consultant will provide services described
in further detail as follows:
Task 1: Centerline Identification, Field Set-up, GPS Network Creation & Mobilization
During Project Initiation, CONSU LTANT will present the finalized Project Approach, which
includes project equipment, software, methodology, schedules, and deliverables. The
finalized approach is based on the CITY requirements and decisions that were initiated
during the Scoping Meeting. CONSULTANT will request that the CITY provide any
existing database, previous inventory of street conditions, road centerlines, Geographic
Information System (GIS) layers, and aerial imagery for project use. Project
communication protocol, documentation, accounting methodologies, data format, and will
be confirmed during the meeting.
CONSULTANT will use the existing centerline data provided by the CITY and create a
pavement database based on the centerline layer. This centerline layer should contain
the GIS linked segments along with any unique ID's that link each segment to the City I
CITY's existing inventory. Each road segment record in the centerline layer will have a
corresponding record in the pavement database. CONSULTANT will work with the CITY
to maintain the unique identifier of each of the road segments on the CITY road network
so that the pavement database will maintain a link to the GIS data.
CONSULTANT will communicate with the CITY to gather required information to define
all the distress types and treatment selections. Based on this information, the Pavement
Condition Index (PCI) rating and treatment selection criteria will be defined to identify
each distress type and its severity, extent, and treatment selection (based on the ASTM-
D6433 testing methodology for roads and parking lots). Each collected GIS road segment
will be populated with its respective PCI as well as any other derivative indices such as
roughness in the form of IRI.
CONSULTANT will provide project management for the duration of the project, including
coordinating and attending meetings via web meetings or in person with CITY, data
research and collection efforts as required, preparing bi-weekly progress reports, and
schedule updates. Bi-weekly progress reports will include the miles collected for the
current reporting period as well as cumulative totals_ An exhibit displaying the roads
14--- 501 tYVIV
collected and not yet collected will also be included. CONSULTANT will work with the
CONSULTANT to review and verify that the data is ready to proceed.
Task 1 Deliverable:
1. The CONSULTANT will attend the project kick-off meeting and perform the initial
data reconnaissance of the GIS data to finalize the extent of survey limits and
milage.
2. The CONSULTANT will provide the CONSULTANT with a centerline assessment
document for review and approval.
3. CONSULTANT will initiate field setup, routing, and GIS integration into the
Roadway Asset Collection (RAC) vehicle.
Task 2: Collect Street Network
The CONSULTANT will collect roadway data and images for 910 test miles of CITY
roads using a Roadway Asset Collection (RAC) vehicle or identical equipment from a
strategic business partner. The CONSULTANT retains a fleet of 4 RAC vehicles and may
lease additional equipment if necessary to meet timeline objectives.
The RAS team consists of a driver and operator who will systematically drive the
automated data collection vehicle on the road segment listings provided by the CITY. The
CONSULTANT will collect pavement data with two passes on all 455 centerline miles of
CITY roadways. CONSULTANT proposes to use its collection vehicle line scan camera
with laser illumination and right-of-way cameras to capture pavement and ROW images
to be used during the pavement rating process. Unpaved roads will not be surveyed.
CONSULTANT will record imagery for deliverables and to identify all right-of-way (ROW)
assets by collecting images at 20-ft maximum intervals with an automated data collection
survey vehicle equipped with a Laser Crack Measurement System (LCMS-2) for
automated pavement data acquisition, Ladybug 3600 camera system for capturing right-
of-way imagery and a laser profiler which includes at minimum two-line lasers for
capturing roughness and ride data. CONSULTANT will perform data field collection on
paved roads using a state-of-the-art Roadway Asset Collection (RAC) vehicle with
following systems mounted:
• Right-of-way georeferenced images with Ladybug 5+ camera: Forward, Left,
Right, and 3601 spherical images.
• LCMS-2 pavement 2D13D imaging.
• Longitudinal profile with 2-line lasers (left and right wheel paths) Distance
measuring instrument (DMI) with an accuracy of +1- 0.1%.
• Differentially corrected GIPS (DGPS) with an accuracy of +1- 2 feet.
• Applanix POSILV 220 to compensate for difficult GPS conditions in urban
environments.
The RAC vehicle collects all pavement and ROW images, IMU, DMI and profiler data
concurrently.
". f yr bm
A RAS automated data collection vehicle
The International Roughness Index (IRI) will be collected using a class 1 road surface
profiler. The road surface profiler meets all ASTM E-950 standards for evaluating the
smoothness of pavement. RAS will utilize the LCMS-2 and Ladybug imagery to identify
all visible distresses. This data will be included in the final pavement layer in GIS prior to
software implementation.
Example imagery from Ladybug 360 camera
Task 2 Deliverables:
1. CONSULTANT will complete field testing on all roadways tagged for survey, 910
total test miles.
Task 3: Pavement Condition Index - Modified ASTM D6433 All with 100% rating (PCI)
CONSULTANT will evaluate the PCI survey results in accordance with ASTM D6433.
CONSULTANT will provide 100% survey of all CITY maintained lanes driven using
CONSULTANT pavement analysis tool, Technical Rating Intelligence Program
(RoadTRIPTM) to evaluate the pavement condition using automated techniques per the
ASTM D6433 pavement distress rating process including the following distresses:
alligator cracking, longitudinal cracking, transverse cracking, block cracking, rutting,
weathering, raveling, potholes, and patching.
Experienced pavement Consultants will review the resultant output for accuracy and
make any corrections that may be needed. The Road TRIPTM software allows the
pavement and right of way imagery to be synchronized and the distress data to be
displayed geospatially to provide another layer of quality assurance.
Pavement Condition Evaluation within Road TRIPTm
Task 3 Deliverables:
1. CONSULTANT will deliver a final GIS file geodatabase containing collected
pavement data (containing the Type, Severity and Extent of distresses along the
road segment as defined by the ASTM D6433 methodology), distresses, and PCI
value.
2. CONSULTANT will deliver all 5 views from the Ladybug imagery and a single view
of the LCMS-2 downward pavement imagery.
GI FJM9
Task 4: Onsite RAS data reviews/Field Pilot
CONSULTANT will work with the CITY to identify and setup a pilot project area so that
some initial sample data can be collected and verified. CONSULTANT will collect data
within the pilot project area and review the result with the CITY and acquire approval for
full size project implementation.
CONSULTANT will provide a pilot study of approximately 5 to 10 miles of roadway, based
on selection by the CITY, to provide a preliminary review of the detailed condition data,
PCI scores, IRI scores, and any asset inventory work captured as a part of the final scope
of services. CONSULTANT will perform a virtual field evaluation, coordinated to include
the CITY, to review the pavement conditions and compare the evaluation and PCI results.
Task 4 Deliverables:
1. CONSULTANT will conduct an on -site field verification of Pilot Roads with CITY
staff.
2. CONSULTANT will make necessary adjustments to processing algorithms upon
the conclusion of the field verification and apply to the network -level inspections.
Task 5: Budget Optimization Street Selector BOSSTm Annual Update - Gold Level
CONSULTANT will develop, configure and set up the pavement analysis operating
parameters within our Budget Optimization Street Selector (BOSSTM) software.
CONSULTANT will configure the maintenance and rehabilitation activities, PCI trigger
points, costs, reset PCI values, completed rehabilitation work since the survey, planned
work, existing budgets, pavement deterioration curve developmenttassignment, and
inflation priorities. CONSULTANT will assist the OWNER with determining the right
treatment (prescription) at the right time by reviewing the County's existing maintenance
and rehabiliation strategies and recommending others that may be a good fit.
The scope will include running at least 10 profile budget runs to establish the budget
model trend and showcasing at least 5 budget scenarios for the 5-year pavement
analysis. We propose to provide these services to develop a 5-year maintenance plan
that is financially optimized and prioritized to meet the needs of the OWNER.
BOSSTM is a cloud -based application with powerful pavement management algorithms
behind it that export the results of the pavement analysis to a user-friendly interface such
as Microsoft Power BI (single user log -in supplied by RAS), Excel Spreadsheets, and
PowerPoint files. All of the results are integrated with the County's existing GIS and
supplied to the County as a File/File Geodatabase for consumption and storage. While
the CONSULTANT will define the scenarios to be run with the OWNER, at a minimum
the following questions should be answered with the budgetary scenarios:
• What is the resultant network PCI at my current funding level?
• What budget is required to maintain my existing network PCI?
• What budget is required to achieve a desired network PCI?
• What budget is required to control the growth in backlog?
The CONSULTANT'S approach to such an analysis involves the following sequences and
OWNER engagements during the process includes:
Maintenance & Rehabilitation Setup — to
ensure the results of the budget model runs
meet the OWNER'S expectations, the
CONSULTANT will discuss the OWNER'S
current Maintenance and Rehabilitation
setup within the pavement analysis setup.
This will include activity set up, PCI trigger
points, and PCI reset scores.
Deterioration Curves — forecasting
pavement conditions requires a detailed set
of pavement deterioration curves for each
roadway traffic classification and pavement material type, as designated by the
pavement management system. The CONSULTANT will develop the deterioration
curves to ensure they reflect realistic degradation rates for the OWNER.
Financial Optimization S Prioritization —
the CONSULTANT'S BOSSTm analysis uses
sound economic logic to prioritize which
street candidates are selected throughout
the multi -year plan. While most pavement
management programs will prioritize by
roadway traffic and condition, the BOSSTM
analysis takes it a step further and introduces
financial optimization into candidate
selection through the use of a "Need Year"
analysims that identifies each segment's cost of deferral. Understanding the "Cost of
Segment Deferral" allows the analysis to maximize the OWNER'S limited funds in the
best manner possible.
Project development — the BOSSTm analysis includes stitching segments (block)
together to form a project, also known as a "management section". The
CONSULTANT will work with the OWNER to review the initial model results and begin
"stitching" segments together to form logical projects that best meet the needs of the
OWNER.
Task 5 Deliverables:
1. The final BOSS deliverable is a Microsoft PowerBl Dashboard (single user log -in
supplied by RAS) that will be exported to Excel and PowerPoint that contains the
results of the pavement analysis and modeling results.
2. The final pavement and analysis results will be delivered as a File Geodatabase
that is ready to be consumed within the County's GIS environment.
3. CONSULTANT will deliver a Final Pavement Condition Survey Report for the
project including: Executive Summary, Project methodology and pavement data,
Current street segment PCI, Budget models and predicted outcome of PCI,
Deferred maintenance backlog, Exhibits showing PCI and street segment length
and pavement type, and Optimized 5-year maintenance and rehabilitation plan.
Task 6: Pavement Widths
The CONSULTANT will use the images from the Ladybug 360 camera system in
conjunction with available aerial imagery to capture the width of pavement for each street
segment to compare with the existing database information. CONSULTANT will provide
the widths for roads with width changes by noting locations of changes by stations and
measuring each section of change, and the addition of lanes or turn lanes.
Task 6 Deliverables:
1. CONSULTANT will deliver (included in the final GIS file geodatabase) pavement
width data for each road segment with area calculations.
Task 7: Budget Optimization Street Selector BOSSTm Annual Update - Silver Level
Task 8: Budget Optimization Street Selector BOSST" Annual Update - Silver Level
(Year 2 and Year 3 Continuing Software Service)
The CONSULTANT will continuing to serve as the CITY'S pavement management
consultant through the BOSS software service. For Year 2 and Year 3 of this agreement,
CONSULTANT is to provide the CITY with the SILVER PACKAGE level of service.
Tasks 7 & 8 Deliverables:
1. CONSULTANT will provide continuing software licensing, maintenance, and
support to the CITY for Year 2 and Year 3.
