  "description": "This crop shows the right-hand portion of two half plans of a skewed bridge — one at deck level (with barrier line, bearing/pedestal squares at 3500 spacing and 30° skew) and one at foundation level (two skewed pile-cap/raft blocks with pile circles at 3750 spacing, separated by a PCC M15 median wall and terminated by independent retaining walls) — drawn to 1:300. Grid bubbles P1 and A1 fix the 40000 (SQ) / 46189 (SK) span, with the centre line of the expansion joint at A1 and traffic direction to Khandwa. At upper right is the 1:2000 key plan showing the proposed structure hatched across the river/drain at chainage 64+412, structure type MJBR, 2X40m span, 30° skew, new construction, with ROW lines, retaining/toe walls and chainage marks 64+400 and 64+500."

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."

The span between P1 and abutment A1 is dimensioned 40000 square / 46189 skew, with the centre line of the expansion joint at A1 and traffic direction to Khandwa. A KEY PLAN (1:2000) at top right locates the proposed structure at CH 64+412, a 2x40 m MJBR with 30° skew, new construction, crossing the Sipra River / earthen drain between chainages 64+400 and 64+500, with ROW lines and retaining/toe walls indicated."

Behind the abutment the drawing documents 600 thk filter media, an independent retaining wall with its own footing (dashed), embankment fill at 1:2 slope with stone pitching, and a tapered approach slab element at the left. The girder is cut by a break line on the left, so only the abutment end of the superstructure is within this crop; no reinforcement detailing or elevations/stations are shown."

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."

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."

  "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."
