ODOT Culvert Inventory & Inspection Program. Background. Ohio defines a bridge as any structure with span or diameter equal to or greater than 10 feet as measured along the centerline of the road. Any structure less than 10 feet is considered a culvert. Bridges in Ohio are inspected annually.

Background • Ohio defines a bridge as any structure with span or diameter equal to or greater than 10 feet as measured along the centerline of the road. Any structure less than 10 feet is considered a culvert. • Bridges in Ohio are inspected annually. • Until now, there was no statewide program for culvert inspection. • Failure of a large culvert can be as detrimental as failure of a bridge.
I-480 Dec. 2001 Background – Impetus for Program
Background • Culvert failures can result in hazards to the motoring public and or lead to expensive emergency projects Costly MOT High Risk Conditions
Background The main purpose of the Culvert Management Program: Reduce or Eliminate the potential for unexpected failures of culverts under Ohio’s roadways and highways – No Surprises!
Prior Practices • Culverts are inspected by maintenance forces ahead of resurfacing projects. This generally works, but has some flaws: • Larger culverts are beyond maintenance crew abilities and were left out of the project scope. • Having no standard practice for evaluating the structure leads to disagreements on remaining life. • Replacements may happen after the resurfacing.
Prior Practices - Inventory Blast!! If only this computer could tell me about the culvert!! *CURSES!* • Inventories existed in various formats throughout the districts. (Spreadsheets, Paper, Bridge Management System) • No centralized way to query culvert data.
Solution Culvert Management Program was created in 2003. It features a Culvert Management Manual that contained two main categories: Inventory Inspection
Culvert Management Program • Program was given to the Districts in 2003, but was never enforced or made policy by Central Office • Central Office IT Department was developing a Culvert Management Database for Statewide use • Developer at Central Office died and the Culvert Management Database stalled to a stop
Culvert Management Program • District 1 & 2 Developed an ODOT Asset Management System • Culverts were included as an item in the Asset Management System
Culvert Database • Office of Hydraulic Engineering (OHE) was developed into an Office in May of 2011. Tasked to develop the Statewide Culvert Management Database. • Database and data collection method developed by ODOTDistrict 1 & 2 was evaluated • ODOT Asset Software – Written for Windows Mobile 6 Operating System • OHE decided to implement this system Statewide in an effort to standardize District data
District Data • 12 Districts within ODOT – Each had different ways of keeping data:
District Data • Some Districts followed Culvert Management Manual • Some Districts followed a portion of the Culvert Management Manual. • Some Districts developed their own items to inventory & inspect
District Data • District data was requested by OHE for “scrubbing” to be rolled into the Statewide Database • Several data sets have been “scrubbed” and rolled with assistance from District 2 • Ongoing effort
Current Status http://d02arcgprd20/Culverttest/
District Data Collection • OHE requested the each District purchase the necessary hardware to facilitate culvert data collection • Trimble GeoExplorers • Most Districts already had hardware • As data is rolled into the statewide database, Districts are trained on how to collect data using the equipment • Data is collected in the field and then downloaded into the database • Current methods only allow ODOT employees to download data
Merge with Bridge Management System (BMS) Database • Culvert database will be merged into a newly developed BMS database • Data collection methods will be supported by new BMS • Hardware used to collect data will change to a Windows 7 Operating System • Currently looking at the Trimble Yuma Tablet • Additional data collection methods (ie: web based input) will be supported • Allows Local Governments to utilize the program
Culvert Database Wow! This is great! I can find out everything about culverts. • Database will assist in management and design policy decisions. • Where the funds need to be spent. • Life cycles based upon different site and/or apprasial condition variables. • Database will allow for easy user interface such as a visual GIS map.
Culvert Database • Database will accept photos, sketches, notes, etc • A maintenance aspect will be added to the database, which assigns responsibility • Anticipate that new Database will be active within 12-18 months • Still in scoping phase of the new BMS
