| The class asks for | Value | How | From |
|---|---|---|---|
| LengthLwants m/mm | not establishedA section cut through a member cannot yield its length; the drawings would need a deck plan or cross-section of the superstructure, which is not in these readings. Note 2 also forbids scaling. | not found | |
| Cross-sectional AreaAwants m2/mm2 | not establishedDeriving an area would require inventing/borrowing a width from a neighbouring element (abutment stem), which is not honest arithmetic for this item. | not found | |
| Instance CountNwants count | 1 countThe section reading lists the 'Girder / box section end diaphragm' with count = 1 (one member cut in SECTION A-A at abutment A2).The count of 1 is only what is shown in this single section at abutment A2; the total number of end cross girders in the bridge (per span end, per girder line) is not established by any reading, so the project-wide count may be greater. Confidence low for that reason. | readcheck | p2 · p02_r07 |
| Material TypeMAT | R.C.C. M45 (reinforced concrete, grade M45; reinforcement Fe 550D to IS:1786) -Note 5, concrete grade schedule: 'R.C.C. END CROSS GIRDER ---- ---M45'. Note 7: reinforcing steel Fe 550D. Note 6: superstructure clear cover 45 mm.The grade is stated outright against the item name 'END CROSS GIRDER' in the general notes on four separate readings; the section crop's 'material not stated' is superseded by these notes. | read | p2 · p02_r04p2 · p02_r05p2 · p02_r04 notes of general design notes and pile load tablep2 · p02_r05 general design notes 1 18 with load table |

Worked out by anthropic/claude-opus-5 from the readings below, which are the source. A derived value shows its arithmetic — check it against the drawing before it is priced.
