Management Engineer
Slide 2
What is Asset Management? ITDs previous pavement &
maintenance management systems ITDs goals for the new asset
management system How TAMS meets those goals
Slide 3
Definition: The practice of managing the whole life cycle
(design, construction, commissioning, operating, maintaining,
repairing, modifying, replacing and decommissioning/disposal) of
physical and infrastructure assets.
Slide 4
TAMS includes: Pavement Management System Maintenance
Management System Future Additions: Fleet Management Network
Manager
Slide 5
A planning tool that models Pavement surface deterioration:
Cracking Roughness Rutting Worst-First and Best-First Philosophy
Worst-First: Fix the worst roads first Best-First: Preserve the
most cost effective roads first
Slide 6
The question: How deficient (bad) are my roads? Recommends
fixing the worst first, even if the worst road has little traffic
and low speed
Slide 7
The question should be: What is the maximum benefit I can get
from our money in the next 5 years? Concentrates on preserving the
best of our impact roads first, considering: Speed Volume
Expectation
Slide 8
Complex Centrally operated, no statewide access Worst-First No
connection to maintenance activities
Slide 9
Labor-intensive Data stored in several different places
Difficult to replicate consistent model results
Slide 10
Goals for TAMS Our new system needed: A relationship between
pavement and maintenance Data available to everyone Repeatable,
reliable analysis results Maximization of cost-to- benefit ratio
Fast analysis of alternatives Network, District, & Project
level functionality
Slide 11
Slide 12
The new TAMS system has: Best-first philosophy Asset Management
Database Pavement Performance Analysis Connection to a Maintenance
Management System Graphing, Reporting, and GIS Maps
Slide 13
We now house data accessible to all statewide TAMS users:
Construction history Traffic and Safety Boring Log and Skid Data
Visual Survey Data Profiler Van Data Signs and Supports Etc
Slide 14
The new system can answer commonly asked questions such as: If
$20 million is added to my budget, how much better will the
pavement deficiency be? How much should we spend to get to a
deficiency of 15%? How much should be spent in each program
category?
Slide 15
Pavement data can be graphed Reports automatically generated
New reports can be user designed TAMS is linked to GIS
Slide 16
ITDs new asset management system (TAMS): Best-First philosophy
Accessible data Robust analysis and mapping features Reliable and
optimized planning for keeping our roads safe and in good
condition
