Methodology

 
3.1 Work with the appropriate branches and personnel from State departments of transportation to obtain all of the following, if available, for each bridge in the Long-Term Bridge Performance (LTBP) Program:  
3.1.1 Original bridge design plans.  
3.1.2 Shop drawings.  
3.1.3 As-built plans.  
3.1.4 Any State design specifications, current at the time of the design of the bridge, which applied to the bridge.  
3.1.5 Any material and/or construction specifications, current at the time of construction, which applied to the bridge.  
3.1.6 Special provisions.  
3.1.7 Foundation design report.  
3.1.8 Soils report.  
3.1.9 American Association of State Highway and Transportation Officials (AASHTO) Bridge Design Specification governing at the time of design.  
3.1.10 AASHTO Bridge Construction Specification governing at the time of construction.  
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 Extract the following types of data from the documents obtained in section 3.1. If appropriate, use the unique element identifiers (FLD-OP-SC-002, Structure Segmentation and Element Identification System) to identify the specific element(s) to which the data apply.

3.3.2 Approach slab details (data collection table items 34–40).  
3.3.3 Approach span details (data collection table items 41–46).  
3.3.4 Span details (data collection table items 47–54).  
3.3.5 Deck drainage details (data collection table items 55–58).  
3.3.6 Deck details (data collection table items 59–115).  
3.3.7 General girder details (data collection table items 116–133).  
3.3.8 Steel girder details (data collection table items 134–164).  
3.3.9 Concrete girder details (data collection table items 165–200).  
3.3.10 Pretensioned concrete girder details (data collection table items 201–213).  
3.3.11 Posttensioned concrete girder details (data collection table items 214–232).  
3.3.12 Bearing details (data collection table items 233–236).  
3.3.13 Joint and railing details (data collection table items 237–243).  
3.3.14 Abutment, pier, and wingwall concrete and reinforcement details (data collection table items 244–327).  
3.3.15 Substructure footing concrete and reinforcement details (data collection table items 328–353).  
3.3.16 Abutment, pier, and wingwall, foundation details (data collection table items 354–388).  
3.4 Storing data, documents, and images:  
3.4.1 FLD-DS-LS-001, Data, Document, and Image Storage—Local, for local storage.  
3.4.2 FLD-DS-RS-001, Data, Document, and Image Storage—Remote, for remote storage.  
3.5 Reporting: Transfer all metadata, data, documents, and images to Federal Highway Administration (FHWA), and/or upload all metadata, data, documents, and images into the LTBP Bridge Portal.

Criteria for Data Validation

 
5.1 Data extracted from bridge documents should be checked by second (independent) person.  
5.2 Where feasible, data will be validated using standard error checking within the Bridge Portal.  

6.

Commentary/Background

 
6.1 This protocol providesguidancefor collecting documents, images, information, and data about the design and construction of each bridge included in FHWA’s LTBP Program. This includes documents, images, information, and data accessible either from the owner or other public information sources, without a visit to the bridge site. Specifically, this protocol focuses on obtaining plans, specifications, and other documents that help define the structural and material characteristics of the bridge at the time it was put into service, and extracting key data items from these documents.  
6.2 This information is to be used to do the following:  
6.2.1 Define the structural and material characteristics of the bridge at the time it was designed, constructed, and put into service.  
6.2.2 Conduct legacy data mining (PRE-ED-LO-001, Legacy Data Mining for Untreated Bridge Deck).  
6.3 When obtaining documents, such as State materials specifications in effect at the time the bridge was designed and constructed; foundation reports; soils report; etc., obtain a PDF version if possible.  
6.4 For identifying the location of longitudinal and vertical stiffeners on the webs of steel girders:  
6.4.1 Specify the element number of the girder to which the stiffener is attached, and indicate near face (NF), for the face of the web that is nearest to the local girder origin, or far face (FF), for the web face that is farthest from the local girder origin.  
6.4.2 Measure and record the x-distance from the local girder origin to the nearest point on the stiffener.  
6.5 Concrete design mix types are defined as follows:  
6.5.1 Performance based: The owner specifies end results that must be met by the concrete, such as 28-day compressive strength and percent air entrainment. The construction contractor is responsible for designing a mix that produces the desired end results.  
6.5.2 Amounts specified: The owner specifies the types and amounts of all ingredients that are used in the concrete mix.  
6.5.3 Hybrid: The owner specifies the types and amounts of some ingredients that are used in the concrete mix and also specifies end results that must be met by the concrete, such as 28-day compressive strength.
