Managing Bridges the Pontis Way

Pontis, the bridge management system of choice for a growing number of States, is now better than ever with the release of Version 4.1. The software can assist highway agencies in organizing their bridge data and analyzing complex engineering and economic factors to make smart decisions about maintaining, improving, and replacing structures. It also allows States to look into the future and show those making funding decisions how much needs to be invested in bridges to minimize the long-term preservation costs and the consequences of different investment levels on bridge condition and performance.

The Pontis system's database can store a complete bridge inventory and bridge condition history, as well as project development and tracking information. The new version of Pontis builds on the project planning capabilities of Pontis 4.0 by integrating its database with two other bridge software programs, Virtis and Opis. Virtis is a load rating program that determines what loads a bridge can handle. Opis is a design program that can perform analysis and specification checking on a variety of bridge types, including steel, reinforced concrete, and prestressed concrete. All three programs are part of the American Association of State Highway and Transportation Officials' (AASHTO) BRIDGEWare line of software.

The new integration capabilities of Pontis, Virtis, and Opis mean that BRIDGEWare users can maintain one bridge database, with the software systems sharing their common bridge information automatically. "Sharing the database information is a great asset. You do less work," says José Aldayuz of AASHTO. "There's no lag in information updates. This real time inventorying means that there's less possibility for error," he adds.

Another benefit is that all three software products undergo the same testing process. In addition, strategic plans for the products are being aligned so that they are in sync. "We're looking at where we want to go in the future with these products, in order to benefit States the most," says Aldayuz. Possible updates being looked at include adding Web-enabled transactions for data entry and more flexible reporting capabilities.

Pontist can assist highway agencies in organizing and analyzing their bridge data.

The Montana Department of Transportation (DOT) uses Pontis to establish performance standards and determine what additional structures projects should be done on top of those already scheduled. "Pontis also helps us to develop a list of proposed maintenance over time," says Paul Jensen of Montana DOT and a member of the AASHTO BRIDGEWare Task Force. "It is helping us attain more consistent management of our bridges. We're smoothing out the peaks and valleys." Montana uses Pontis in conjunction with Virtis and Opis. "We have one central location for all of our data now, whether we are rating structures or doing appraisals. The programs can recalculate data for all of our needs," says Jensen.

The California Department of Transportation (Caltrans) started using Pontis in 1992. "At that time it was revolutionary. There was no such thing as a bridge management system," says Michael Johnson of Caltrans. With Caltrans responsible for 25,000 bridges in the State, Pontis allows the agency to keep all the data in one database. "Pontis forms the core of our database. We routinely use it for budgeting and to assist with our 10-year preservation plan. It's the only real tool we have to look into the future," says Johnson.

California also used Pontis to analyze six different designs that were being considered for the replacement of a bridge over the Carquinez Straits. Pontis calculated the expected annual maintenance costs for each design. These maintenance cost comparisons were combined with initial construction cost estimates to produce life-cycle cost estimates for consideration in the final design selection. "This software has practical applications that have yet to be discovered. You just have to think a little outside the box and your bridge data can work for you," says Johnson.
