| The class asks for | Value | How | From |
|---|---|---|---|
| LengthLwants m/mm | 2'-4" ft-inThe diaphragm detail directly dimensions the concrete diaphragm vertically as 2'-4"; this is taken as the diaphragm cross-sectional length/depth. | read | p5 · p05_r04 1 cl typ |
| Cross-sectional AreaAwants m2/mm2 | 180644.48 mm210" × 2'-4" = 10 in × 28 in = 280 in2. Converting for the required metric area unit: 280 in2 × 645.16 mm2/in2 = 180644.48 mm2.The detail directly identifies the diaphragm as 10" thick and 2'-4" vertically. These are the two dimensions of the rectangular diaphragm cross-section. | derived | p5 · p05_r04 1 cl typ |
| Instance CountNwants count | 6 count2 concrete diaphragms in SPAN 1 + 2 concrete diaphragms in SPAN 2 + 2 concrete diaphragms in SPAN 3 = 6 concrete diaphragms.Each of the three span deck plans explicitly identifies two concrete diaphragms. The page 5 detail is a typical detail and is not added as a separate installed instance. | derived | p2 · p02_r01 deck planp3 · p03_r01 deck planp4 · p04_r01 deck plan |
| Material TypeMAT | concreteThe plan object identifies the item material as concrete, and the detail labels it as a concrete diaphragm. | read | p2 · p02_r01 deck planp5 · p05_r04 1 cl typ |

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