Bridge 10 Sketch and Dimensions.pdf

This document is a USDA Forest Service bridge inspection and documentation template for recording structural specifications of concrete bridges. The template provides a standardized format for capturing critical bridge dimensions and characteristics during field inspections.

The form documents a single-span concrete bridge with the following key specifications: out-to-out width of 16 feet 3 inches, travel width of 14 feet 2 inches, curb width of 12 inches, deck thickness of 14 inches, and bridge full length of 46 feet 6 inches. The NBIS length is recorded as 43 feet 6 inches, with bearing distance of 22 feet 6 inches across two spans. The superstructure is identified as reinforced concrete construction with a cast-in-place deck depth of 14 inches. The wearing surface consists of asphalt with a depth of 14 inches. Curb and railing specifications include a W-beam height of 24 inches. The substructure is constructed of reinforced concrete with wall-type elements. The document includes checkboxes for recording additional structural details such as beam/slab configuration, skew angle (marked at 0 degrees), and provisions for photographic documentation of the bridge surface, understructure, wearing surface, railing, stringers, slabs, and substructure conditions. This template is designed for systematic field data collection to support bridge maintenance and condition assessment programs.
