1 Asset Management Initiatives in TxDOT Bobby Littlefield, P.E. Paris District Engineer October 12, 2011

2 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.

3 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.

4 Asset Management: Engineering + Business Decisions Physical Assets = Infrastructure Primarily concerned with roadway assets that exist on public right-of-way

5 TxDOT s 3 Tier Scope Asset Inventory (Data Collection) Data Manipulation (Applications, GIS) Decision Making (Performance-based)

6 Why Asset Management? Aging Infrastructure National Context Growing Congestion Funding Shortfall Focus on System Performance Asset Management is Imperative

7 What is TxDOT doing to fill this need? Asset Management is included in the Strategic Plan Goal 3: Maintain the Existing Texas Transportation System Objective: Develop optimal asset management programs to protect existing infrastructure investments

8 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

9 How Does Asset Management Work Long-term view of assets More robust management and monitoring systems

10 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

11 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.

12 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)

13 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

14 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

15 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.

16 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.

17 Web based IR Projects to support overall Asset Management Goal LRS Modernization (HPMS-GIS) PMIS Modernization (Mustang) BRINSAP Modernization (PONTEX) MMIS Modernization (COMPASS)

18 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.

19 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)

20 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

21 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.

22 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 )

23 PMIS Modernization Mustang Project (currently in planning stage) Highlights of the project Modernize database storage Improve methods of uploading data from collection vehicles

24 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.

25 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

26 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

27 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.

28 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

29 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

30 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.

31 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).

32 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.

33 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.

34 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."

35 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.
