The class asks forValueHowFrom
HeightHwants m/mmnot establishedThe elevation identifies two interior bent columns but provides no vertical dimension, top and bottom elevations, or other stated values from which the bent-column height can be calculated.not found
Instance CountNwants count2 countThe bent column object is explicitly listed with count 2, with one column visible at each of the two interior bents in elevation.readp1 · bridge_1_right
Concrete Gradefcknot establishedNo concrete strength, class, or grade is stated for the bent columns in the supplied crop reading.not found
Cross-sectional AreaAwants m2/mm2not establishedThe bent columns are described as rectangular, but no column cross-section dimensions are stated, so an area cannot be calculated.not found

Worked out by openai/gpt-5.6-terra-pro from the readings below, which are the source. A derived value shows its arithmetic — check it against the drawing before it is priced.

  "description": "The crop contains a plan at the top and an elevation at the bottom, rather than a single elevation view. The plan documents two parallel skewed bridge layouts over the Central of Georgia Railroad Company existing track and a future track, with bents identified for left and right bridge alignments. The elevation shows the bridge span arrangement, end walls, interior bent columns on pile caps and piles, bearing conditions, fencing, and groundlines."
