| The class asks for | Value | How | From |
|---|---|---|---|
| LengthLwants m/mm | not establishedAll five crops that dimension the pier cap in plan give only one horizontal figure, which the drawings themselves label 'pier cap width' (SQ 3640 / SK 4203). No second, orthogonal plan dimension for the cap itself is stated (the 1500 value belongs to the RCC column pier, a different item). Without a second figure, 'Length' cannot be read or derived. | not found | |
| WidthWwants m/mm | 3640 (SQ) / 4203 (SK) mmDirectly read from drawing labels '3640(SQ)' and '4203(SK)' each explicitly annotated as 'pier cap width' in Section B-B views.All four sectional views of pier P1 consistently label this dimension 'pier cap width', with a square (SQ) value of 3640 mm and a skew (SK) value of 4203 mm due to the skewed bridge alignment. Both values are explicitly owned by the pier cap object, so this is a direct read, though which one governs (square vs skew) is a design choice not stated. | read | p2 · p02_r10p2 · pier_p1p2 · p02_r09 section b bp2 · p02_r10 section b b |
| ThicknessTwants m/mm | 1500 mm750 (upper tier) + 750 (lower tier) = 1500 mm, matching the directly labeled 'Total pier cap depth/height' of 1500 mm in the same views.The pier cap is shown as a two-tier block, each tier 750 mm deep, summing to a total cap depth/height of 1500 mm, which is also independently stated as 'pier cap height' / 'Total bearing pedestal height' / 'Total pier cap depth' across multiple crops, confirming the value directly. | derived | p2 · p02_r10p2 · pier_p1p2 · p02_r09 section b bp2 · p02_r10 section b b |
| Instance CountNwants count | 1 countObject list in crop 'bridge_pier_and_foundation_p02_r10' states 'Pier cap / bearing seat' count: 1 for pier P1; no other pier cap marks appear in the supplied readings.Only pier P1 is documented in the given crops, with a single pier cap sitting atop the single column pier. No other pier marks (e.g., P2, P3) are present in the supplied readings, so the count established here is 1; a full bridge may have more piers not covered by these crops. | read | p2 · p02_r10p2 · pier_p1 |
| Concrete Gradefck | M50General design notes concrete-grade table lists 'BEARING PEDESTAL' = M50; the item's aliases explicitly include 'bearing pedestal / pier cap block' and 'bearing pedestal'.The notes table separates 'ABUTMENT & PIER' (M45) from 'BEARING PEDESTAL' (M50). Since the pier cap is the bearing-pedestal element (per the item's alternate names) sitting atop the pier column, its concrete grade is M50, distinct from the pier column's M45. This linkage relies on alias matching rather than an explicit 'PIER CAP' row, so confidence is lower. | readcheck | p2 · p02_r06 notes of general design notes |
