  "description": "This crop is a paired half plan of a skewed (30°) two-carriageway highway bridge: the left half shows the deck level and the right half (partly cut off at the sheet edge) shows the corresponding foundation level, both at 1:300. It documents the general arrangement — approach slabs and footpaths at abutment A1, one 40000(SQ)/46189(SK) span to pier P1, five girder lines at 3500 c/c per carriageway, RCC crash barriers with deck drainage spouts at 5000 typical, a 2900 median within an 80000 ROW, and pile groups/foundation outlines at A1 and P1. Only half of the structure is drawn; the second span beyond P1 and the retaining wall callout on the right are incomplete in this crop."

  "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."

  "description": "This crop is a full-page block of general notes for a bridge drawing, enclosed in the sheet border, with no graphical construction detail. It states dimensioning conventions, live load design cases, concrete grades for each structural component, reinforcement cover and steel grade, wearing course thickness, expansion joint and drainage requirements, backfill and seismic/exposure data, and cross-references to alignment, plan-profile and miscellaneous drawings. It closes with a small table of tentative working pile loads (max. vertical 300 T, lateral 50 T), useful for specification and material take-off assumptions rather than direct quantity measurement."
