Long-Term Bridge Performance (LTBP) Program Protocols, Version 1

	Bridge Inspection Records LTBP Protocol #: PRE-ED-BD-005

1. Data Collected

1.1

Inspection information, metadata, data, documents, and images collected by the owner’s inspection staff or owner’s consultant inspection forces during the current and past biennial National Bridge Inspection Standards (NBIS) bridge inspections and any other inspections performed.

2 Onsite Equipment and Personnel Requirements

2.1

Equipment:

2.1.1

Computer.

2.1.2

Scanner.

2.2

Personnel: PRE-PL-LO-005, Personnel Qualifications.

3 Methodology

3.1

Work with the bridge owner to obtain the required inspection information (data collection table items 9–13).

NOTE—All current and past National Bridge Inspection (NBI) data and all current and past AASHTO element level data will be obtained through separate processes.

3.2

If the bridge information exists only in paper form, scan that information into an electronic format so it can be stored in the LTBP Bridge Portal.

3.3

Storing data, documents, and images:

3.3.1

FLD-DS-LS-001, Data, Document, and Image Storage—Local, for local storage.

3.3.2

FLD-DS-RS-001, Data, Document, and Image Storage—Remote, for remote storage.

3.4

Reporting: Transfer all metadata, data, documents, and images to FHWA, and/or upload all metadata, data, documents, and images into the LTBP Bridge Portal.

6 Commentary/Background

6.1

This protocol provides guidance for collecting records and data compiled by the owner during biennial NBIS inspections, as well as other periodic inspections.

The information in the owner’s inspection files is an excellent resource for understanding the history of the bridge before beginning LTBP field data collection.

6.2

In accordance with the NBIS, every bridge (on public highways) must be inspected at least every 2 years. Inventory and inspection data collected during these inspections is reported to FHWA and stored in the NBI database. In addition to the required data for the NBI database, most State bridge owners keep detailed records of the inspection findings—details of deficiencies, photographs, and other information documenting the condition of the bridge and all of its elements.

6.3

During the biennial inspections, for bridges other than culverts, NBIS inspectors record NBI condition ratings for NBI items 58 (deck), 59 (superstructure), and 60 (substructure). These ratings are included in the inspection reports. These data will also be collected for all LTBP bridges under a separate process.

6.4

During the biennial inspections, depending on the owner’s policies, inspectors may also estimate and record element level condition state data in accordance with reference 7.2.3 or 7.2.4 below. These data will be collected for all LTBP bridges under a separate process.
