  "description": "This crop is a block of general design notes for a bridge, ending with a small two-row tentative working pile load table. It states dimensional conventions, live load design cases (IRC Class A / 70R / SV), concrete grades for each structural component, clear cover values, reinforcement grade, expansion joint and drainage spout specifications, wearing course thickness, seismic/wind zone and exposure, backfill properties behind the RE wall, and piercap/bearing pedestal level assumptions. No structural geometry is drawn here; quantities must be read from other sheets, using this crop only for material grades, covers and the stated 300 T vertical / 50 T lateral tentative pile working loads."

It also contains a small table of tentative working pile loads (max. vertical 300 T, lateral 50 T) and a secondary notes box instructing that the drawing be read with other sheets of the same drawing number. No structural geometry is drawn in this crop, so quantities must be taken from the referenced detail and miscellaneous drawings; the notes only supply material grades and cover values for the take-off."

It shows, per carriageway, a 16550 wide cast in situ RCC deck with 13500 carriageway, 1500 footpaths, RCC crash barriers and 50mm wearing coat at 2.5% cross fall, supported on five girder lines at 3500 centres over an abutment cap/cantilever wall, which in turn sits on a pile cap founded on five piles at 3750 centres. Median details (2900 wide median, cantilever median wall, 20mm polysulphide-sealed gap and PCC M-15 below), embankment side slopes at 2:1 with stone protection, and the full set of abutment cap top, pile cap top/bottom and pile tip levels for both A1 and A2 (left and right side) are annotated for quantity take-off."

  "description": "This crop is a transverse section through the pier location of a twin-deck (dual carriageway) bridge, drawn at 1:150. It shows, for each carriageway, a 16550 wide cast-in-situ RCC deck with 50mm wearing coat at 2.5% cross fall, 13500 carriageway, 1500 footpath and RCC crash barriers, supported on bearings over a tapered pier cap carrying three pier columns, founded on a 16550 long pile cap with six piles at 3000 centres. Levels are annotated for pier cap top (515.384 L/S, 515.567 R/S), pile cap top (503.316) and bottom (501.516) and pile tip (476.566), with ROW lines at both extremities and a general note block at right."
