It documents the superstructure (precast PSC girders, deck with continuity over the pier, RCC crash barriers, pot-PTFE bearings marked FR/FX, expansion joints) and the substructure/foundation (wall type abutments, pile caps on 1200 mm dia cast-in-situ piles, approach slabs on PCC leveling course, independent retaining walls with filter media, stone pitching and launching apron). A tabulated schedule below gives chainages, finished road levels and ground levels at LHS/RHS for each of A1, P1 and A2; the notes block at lower right is partially cut off at the crop edge."

  "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 general design notes block for a bridge, listing dimensional conventions, live load design cases (IRC Class A / 70R / SV), concrete grades for each structural component, clear cover requirements, reinforcement grade, wearing course and expansion joint specifications, seismic/wind zone and exposure classification, and backfill properties. It also contains a small table of tentative working pile loads (max. vertical 300 T, lateral 50 T) and a cross-reference to miscellaneous drawings for approach slab, gap slab, crash barrier and drainage spout details. No graphical structural views are shown; a second small NOTES box at bottom right instructs the drawing be read with other sheets of the same drawing number."

It also shows the substructure and foundations — wall type abutments and pier on pile caps (12300 wide at abutments, 5100 at pier) supported on 1200 dia RCC cast-in-situ piles at 3600 spacing — together with approach works: 300 thk approach slabs on 150 thk PCC levelling course, independent retaining walls, stone pitching over 600 thk filter media, launching aprons and 2:1 embankment slopes. Below the elevation is a levels table giving chainages, FRL and existing ground levels at LHS/RHS for A1, P1 and A2, and at the right edge a partially cut-off general NOTES block covering units, loading class and concrete grades."

  "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."

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."

  "description": "This crop is a full transverse cross section (section A-A) taken at the abutment locations A1 and A2 of a divided (twin-deck) bridge, drawn to 1:150 within an 80000 wide right of way. 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."
