- A P4 is deleted when |z_P4 − z_bar| < (d_P4 + d_bar)/2 against B5 and B1
(the 확대기초 top layer, from the 상면). B11/B12 are not checked (Q-C9 무시).
- The P6 crossties start from the first kept P4.
- Tests: the document's example keeps all 8; B5 moved to −70 deletes the P4 at
−60; a P4 just outside the limit is kept.

- Nominal bar diameters (H29 28.6, S32 31.8, …) as used by the documents. With
them, C7/C8 l_s = 1.3·l_d(28.6, fck 27) = 1717.6, which is the document's 1717.
- C1–C8 (코핑철근.md §5): width layout 127 · 110.5 · 21@125 · 110.5 · 127 with 24
bars (12 + 12); heights 43.284 / 43.227 / 43.170; top bar lengths 12744 /
12629.6 / 12515.2; bottom pieces ≈ 7448.
- C4 (기둥철근.md): P1 r 875 and P2 r 843.2; couplers P1 +3/6/9/12 m, P2 +150;
230 + 230 main pieces and 368 couplers; tie radius 900.45; P3 38 at @300 from
2.340; P5 19 at @120; P4 8 at @120 from −0.060; P6 8 levels × 4 = 32, length
≈ 2071.
- Not yet: C4 interference checks (P4 vs B11, Q-C9), bar lengths of P3/P5/P4
and coupler shapes, the coping/column drawing checks, and the ③ screen.
