  "description": "This crop is an elevation view of a concrete pile cap / bent cap beam supported on multiple piles between two end columns, with top-of-cap elevations, bar reinforcement marks (2-442, 2-445A/B/C, 4-1040, 4-441, 7-441), and detailed bay spacing dimensions given in feet-inches along the bottom. Section cut lines A-A and B-B are indicated at two locations along the beam, and the overall length of the structure is dimensioned as 44'-1 1/16\". This likely documents a bent/pile cap elevation for a bridge substructure, showing elevations and reinforcement layout rather than the full structure."
