Appraisal
The Inspection > Appraisal task allows the user to enter a bridge's NBI structure appraisal information, including clearances, NBI load ratings, and more. The user can also view the calculated appraisal ratings for the selected bridge, operating and inventory ratings, and the structure's posting status.
Appraisal Groupings
Structural Appraisal
The Structural Appraisal grouping contains several structural NBI fields to be completed.
Calculated Appraisal Ratings
The Calculated Appraisal Ratings grouping contains information that is calculated on the database level, including NBI fields such as structural evaluation and sufficiency rating. The Bridges > Suff Rate task can be used to override the calculated values in this section.
The Bridge Condition rating displays a bridge status of Good/Fair/Poor and stores it in the database at inspevnt.bridge_condition. This status is determined by the lowest rating of the NBI condition ratings for deck, superstructure, substructure, and culvert. The status is as follows:
- Good - 9, 8, 7
- Fair - 6, 5
- Poor - 4, 3, 2, 1
Deck: 7
Superstructure: 6
Substructure: 5
Culvert : Null
Because substructure is the lowest NBI condition rating, it will be used to determine the Good/Fair/Poor status. With "5" as its rating, the bridge status will be set to Fair.
Clearances
The Clearances grouping contains vertical and lateral clearances and navigation data NBI fields to be completed.
NBI Load Ratings
The NBI Load Ratings grouping contains load rating NBI fields and alternate fields to be completed.
