Conclusion
Wisconsin Highway Research Program (WHRP)
WHRP established in 1998 by the Wisconsin Department of Transportation in collaboration with the University of Wisconsin-Madison
Mission: Discover better ways to design, build and reconstruct the state’s highways.
WHRP
Research areas• Flexible pavements• Rigid pavements• Geotechnical• Structures
$1 million average annual budget
WHRP BMS Next Generation Objectives
Phase I• Migrate Common Recognized (CoRe) elements to
comply with MAP-21 requirements in HSI system• Test migration process in a small group of bridges
Phase II• Gather and summarize Wisconsin costs for element
protection, repair, rehabilitation and replacement• Develop Wisconsin element deterioration models• Develop Wisconsin utility functions• Develop Wisconsin risk assessment model
WisDOT HSI System Structures inventory and inspection data storage Fully web-based J2EE (Java) application with Oracle 11g Home-grown: created in 2003, own and maintained
application Recent upgrades
• Support new elements and element defects • April 1, 2014: Began inspections based on 2013 AASHTO
manual for bridge element inspection (one of the first!)• HTML5 -> browser-agnostic, multiple file upload• Responsive design -> mobile devices, tablets and similar gadgets• Enhanced querying and reporting• Training resources:

WisDOT Overall BMS: HSI-BrM HSI (WisDOT’s BrM sans modeling) BrM 5.2 for modeling HSI inventory and inspection data -> BrM
Differences between CoRe Element Guide and AASHTO 2013 Manual for
Bridge Element InspectionMAP-21 Requires to inspect and report the National Bridge Elements (NBEs) Decks are no longer inspected as each Protective systems (i.e. overlays and paint) are
now separate elements associated with a NBE All elements have four condition states The concept of Defects replaces the Smart Flags
defined in the CoRe Guide
The conversion process Engineering Concepts
• Custom elements and defects language driven and written by WisDOT
• Very detailed instructions and record keeping used in the process• WisDOT put together a matrix of all elements to be
used in the migration• Dynamic and prompt collaboration between client and
consultants• Three iterations in writing the rules• Final version of element description and rules approved
by WisDOT
The conversion process Software Concepts
• AASHTO’ s migrator was used to connect to the former HSI and extract element information for ALL state bridges
• Three iterations were done based on engineering requirements
• A .NET tool was created to read the XML output files from the translator and place the migrated information in the new HSI by just clicking a button
• Element information was migrated for all state owned bridges allowing MAP-21 compliance by April 2014

Conclusions Phase I
The migration process can be effectively completed outside BrM
There is a bigger chance for success if the engineering portion is driven by the State Agency
Prompt attention and clear directions contributed to the success of this project
Quick reaction to directions from consultants was another key factor to the success of this project
