What is Asset Management?
• FHWA defines it as: “… a systematic process of maintaining, upgrading, and operating physical assets cost-effectively. It combines engineering principles with sound business practices and economic theory, and it provides tools to facilitate a more organized, logical approach to decision-making.”
What is Asset Management?
• AASHTO defines it as: “… a strategic and systematic process of operating, maintaining, upgrading and expanding physical assets effectively throughout their lifecycle. It focuses on business and engineering practices for resource allocation and utilization, with the objective of better decision making based upon quality information and well defined objectives.”
Asset Management: Engineering + Business → Decisions
Physical Assets = Infrastructure
Primarily concerned with roadway assets that exist on public right-of-way
TxDOT’s 3 Tier Scope
•Asset Inventory (Data Collection) •Data Manipulation (Applications, GIS) •Decision Making (Performance-based)
Why Asset Management? National Context
•Aging Infrastructure •Growing Congestion •Funding Shortfall •Focus on System Performance •Asset Management is Imperative
What is TxDOT doing to fill this need?
• Asset Management is included in the 2011-2015
Strategic Plan Goal 3: Maintain the Existing Texas Transportation
System Objective: Develop optimal asset management
programs to protect existing infrastructure investments
How Does Asset Management Work
• Improved decision-making supported by policies,
performance-based goals, performance measures, and appropriate service levels
• Decisions are based on accurate data, and sound
engineering and economic analysis
How Does Asset Management Work
• Long-term view of assets • More robust management and monitoring systems
The most successful asset management programs
• Have performance measures that guide investment decisions
• Adopt a ‘preservation first’ strategy for their investment
priorities • Moved away from a “worst first” investment strategy,
and instead have adopted investment principles that are based on life cycle costing
Current TxDOT Practice
• Not clearly defined and lacks organization. “Everyone is doing their own thing.”
• Data is collected multiple times, by multiple D/D/O/R for
several purposes. Redundant and inefficient. • Data is manipulated in legacy systems (primarily
obsolete mainframe), stored in several locations and lacks a central repository.
Short Term Initiatives Data Collection
• A data collection pilot project is being phased in across regions and districts. This project will demonstrate a method to efficiently and effectively collect data by sharing equipment and personnel using the OneDOT methodology.
• Establishes uniform performance measures for all data
collectors • Establishes a Regional Data Collection Manager
(RDCM)
Short Term Initiatives Data Collection
• Data Types to be collected: – Texas Reference Marker (TRM) Database
• Maintain inventory data • Notify TPP of roadway additions, deletions, and
length changes • Provide information to District personnel
– Highway Performance Monitoring System (HPMS) • Collects data on sample sections • Reviews no fewer than 1/3 of sample sections • Updates HPMS database
Short Term Initiatives Data Collection
• Data Types to be collected: – Pavement Management Information System (PMIS)
• Network level – operate profiler vehicles to collect ride/rut; operate skid trailer; contracted visual ratings for cracks and distress
• Project level – FWD, ride, skid, GPR
– County Road Database • No district compenent currently • Collect IRI/PSR data
Short Term Initiatives Data Collection
• Each region will have 2 person in-house teams to collect PMIS ride/rut data by profiler vehicles. Teams will each collect data over approximately 13,000 – 14,000 lane miles.
• A backup profiler vehicle will be assigned to each
region. • In addition to the RDCM, a pavement specialist will be
assigned to the region to serve as a backup and to collect project level data.
Short Term Initiatives Data Collection
• Each district will have one Data Collection Coordinator to serve as a point of contact for all data collection, specifically PMIS and TRM. Metro districts may need two coordinators.
• Districts have received GPS units and are now
collecting geospatial information for TRM elements.
Short Term Initiatives
Web based IR Projects to support overall Asset Management Goal • LRS Modernization (HPMS-GIS) • PMIS Modernization (Mustang) • BRINSAP Modernization (PONTEX) • MMIS Modernization (COMPASS)
Short Term Initiatives LRS Modernization
HPMS-GIS Project (currently in development stage – phase 1)
TPP has begun a multi-phase project to modernize the methods used to collect, store and review the data they provide to the FHWA. The first phase will modernize the linear referencing system used by TxDOT. When completed the agency will have one unified LRS available to applications.
Short Term Initiatives LRS Modernization
Highlights of Phase 1 • Replace multiple mainframe systems with a single
geospatially database environment • Allow Web-based editing and entry of data
(replaces mainframe) • Automated and integrated linear referencing
method conversion (CS/MP, TRM + offset, DFO, intersection + offset, lat/long, address)
Short Term Initiatives LRS Modernization
Highlights of Phase 1 • Enhanced quality control of GIS data entry • Web-based ad-hoc query, analysis, and reporting
tools • Future phases will modernize the editing, reviewing
and reporting of the data
Short Term Initiatives PMIS Modernization
Mustang Project (currently in planning stage) CST has begun the process of modernizing the MapZapper system used by TxDOT for pavement management. When completed the agency will have a modernized system to view and manage pavement data.
Short Term Initiatives PMIS Modernization
Mustang Project (currently in planning stage) Highlights of the project
• Replaces the current MapZapper application • Provide a GIS map to view/analyze pavement
conditions • Provide a method to view roadway condition images
along a defined route (similar to Google StreetView®)
Short Term Initiatives PMIS Modernization
Mustang Project (currently in planning stage) Highlights of the project
• Modernize database storage • Improve methods of uploading data from collection
vehicles
Short Term Initiatives BRINSAP Modernization
PONTEX Project (currently in implementation stage) BRG has been working on the process of modernizing the BRINSAP system used for bridge class structure management. When completed the agency will have a modernized system to view and manage bridge data.
Short Term Initiatives BRINSAP Modernization
PONTEX Project (currently in implementation stage) Highlights of the project
• Replaces the current mainframe BRINSAP application • Provide a GIS map to view/analyze bridge condition
data
Short Term Initiatives BRINSAP Modernization
PONTEX Project (currently in implementation stage) Highlights of the project
• Provide a method to report on funding strategies per FY
• Provide a method to visualize structure rating • Expands detail of data collected and reported for
each structure
Short Term Initiatives MMIS Modernization
COMPASS Project (currently in implementation stage) MNT has been working on the process of modernizing the MMIS system used for management of maintenance activities. When completed the agency will have a modernized system to view and manage maintenance data.
Short Term Initiatives MMIS Modernization
COMPASS Project (currently in implementation stage) Highlights of the project
• Replaces the current mainframe MMIS application • Provide a method to report equipment usage • Provide a method to report on costs of maintenance
work
Short Term Initiatives MMIS Modernization
COMPASS Project (currently in implementation stage) Highlights of the project
• Provide a method to develop budgets for maintenance sections
• Provide a method to inventory assets within the
section
Short Term Initiatives
• Asset Management Workgroup – A workgroup comprised of District Engineers,
Division Staff and Regional Staff has been working to evaluate and prioritize asset management cataloging efforts. A comprehensive Business Plan is being developed.
Long Term Vision • Data Collection effort will be expanded statewide to
ensure a single unified method to collect assets. • Additional methods of collection will be identified and
proven (i.e. video logging/imagery from 360 degree cameras mounted on profiler vehicles; radio frequency identification (RFID); 3-D measuring system for rut and crack detection, edge dropoffs and cross slope).
Long Term Vision • Scope of unified data collection will include data
related to bridges, traffic operations and environmental features.
• Existing and future applications consuming services
from an LRS or spatial information will be fed from one centralized data repository.
Long Term Vision • Decision making using optimization software tools
based on linear programming models. - Pavement Management System/ 4 Year Pavement Management Plan (PMP) • Progress will be monitored to ensure consistent
alignment with directions provided by FHWA and AASHTO.
Per Al Alonzi, FHWA – "The transition of the management of the Federal-aid Highway Program will be from one that allows states to make program and project decisions based on eligibility criteria to a program that utilizes performance goals and measures to hold states accountable for improved system performance."
Who is responsible for Asset Management?
• Asset Management is everyone's job! • No one employee or one division or one district or one
region can make asset management happen.
It takes to make it happen.
