Data Collected

 
1.1 Cost data related to the design and construction of the bridge.  

2.

Onsite Equipment and Personnel Requirements

Methodology

 
3.1 Work with the bridge owner to identify and obtain cost data for the design and construction of the bridge.  
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 Long-Term Bridge Performance (LTBP) Bridge Portal.  
3.3 Extract the following cost information from bridge design and construction documents:  
3.3.1 Bridge design cost, including costs by contract personnel and in-house staff (data collection table items9–11).  
3.3.2 Costs for the deck, including concrete materials, forming, finishing (including tining or grooving), and curing. Regarding reinforcing steel costs, the cost per pound is desired. This includes fastening clips, wires, separators, chairs, and other materials used in maintaining the reinforcement in place. The costs for deck sealers are applied during the initial construction of the bridge (data collection table items 12–29).  
3.3.3 Costs for deck joints (data collection table items 30–38).  
3.3.4 Cost of bearings (data collection table items 39–51).  
3.3.5 Costs for concrete superstructure items – This includes girder fabrication, transportation, and erection costs, plus diaphragms, approach slabs, median barriers, and parapets (data collection table items52–65).  
3.3.6 Costs for steel superstructure items – This includes girder fabrication, transportation, and erection costs, plus connections, welding, stiffeners, and cross-frames. Costs for corrosion protection systems for steel superstructure members (shop applied or field applied) (data collection table items 66–81).  
3.3.7 Costs of concrete substructure items (data collection table items 82–93).  
3.3.8 Costs of steel foundation items (data collection table items 94–97).  
3.3.9 Costs of timber foundation members (data collection table items 98–100).  
3.3.10 Total bid price for construction of the bridge (data collection table items 101–102).  
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 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 a 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 data to document the costs of designing and constructing the bridge. These cost data are used in life-cycle cost analysis of bridges. Please note that other types of cost data are gathered in PRE-ED-BD-006, Bridge Maintenance Records and Cost Data.  
6.2 States’ cost data are typically in the form of unit costs, such as cost per square foot, cost per gallon, or cost per each item. Therefore, the LTBP Program will store unit cost data.  
6.3 Bridge deck designers usually try to minimize water accumulation by establishing a cross slope with drainage channels and by deck surface texturing. Two methods of producing texturing are:  
6.3.1 Tining – The deck is dragged transversely with a metal rake while the concrete is still plastic. Although this method can produce grooves deep enough for a high-friction surface, the grooves are not uniform and are limited in depth.  
6.3.2 Grooving – A better method of getting maximum deck drainage is to saw grooves into the pavement transversely, or perpendicular to the direction of traffic, after the concrete has cured. Bridge deck grooving is achieved by diamond saw blades that are ganged, or arranged at spaced intervals, on a shaft. Grooving can begin after deck concrete has cured to the minimum required compressive strength. Grooving is usually done perpendicular to the centerline to within about 1 foot of the gutter, curb, or parapet lines.
