Values kept as drawn, in the drawing's mm units.Dimension is explicitly attributed to the pier cap (not the 1500 pier shaft or the 5100 pile cap), and given in both square and skew forms as the drawing writes them.readp2 · p02_r09p2 · pier_p1p2 · p02_r09 section through column pier with pile cap and bored piles

It documents the 230 thick deck slab with deck continuity over the pier, two precast PSC girders (2650 deep) on pot-PTFE bearings set 1170(SQ)/1350(SK) each side of the pier centreline, RCC seismic stoppers, a two-tier pier cap 1500 deep and 3640(SQ)/4203(SK) wide, a 1500 wide RCC column pier extending below ground level, and an 1800 deep RCC pile cap 5100 wide on 1200 dia bored cast-in-situ piles at 3600 centres with 750 edge distances. The right edge of the crop is cut, showing a partial '25' dimension and truncated text belonging to an adjacent view."

Dimensions are given in both square (SQ) and skew (SK) values for bearing offsets, deck gap and pier cap width. Girder spans are cut off at break lines each side, so only the pier region is documented in this crop."
