Bridge 9 Sketch and Dimensions.pdf

This file contains technical specification sheets and a data collection template for bridge structures, specifically for the USDA Forest Service Computation Sheet. The document includes two hand-drawn computation sheets labeled Bridge #9 and Bridge #10, which appear to be preliminary engineering sketches showing bridge elevations, beam configurations, pier details, and various structural dimensions including span widths, deck heights, and bearing seat specifications.

The third page is a standardized single span concrete bridge documentation form that serves as a template for recording bridge inventory and structural data. Key parameters to be documented include out-to-out width (16 ft 6 in), travel width (14 ft 6 in), curb width (12 in), deck thickness (14 in), bridge full length (43 ft 10 in), NBIS length (39 ft 8 in), and wearing surface depth (14 in). The form requires selection of superstructure type (longitudinal slab, 3-sided box slab, trideck, or bulb-T), wearing surface material (asphalt or other), curb/railing type, deck construction method, substructure type (piling, crib, wall, or other), and substructure material (timber treated/untreated, steel, reinforced concrete, or gabion). Additional documentation includes skew angle specifications and requirements to photograph bridge features including wearing surface, railing, and substructure components.
