Total LengthL_totalwants m/mm80 m (2 × 40 m, square) mKey plan proposal table states PROPOSED SPAN: 2X40m for the proposed MJBR at CH 64+412. Total length of the proposed structure footprint = 40 m + 40 m = 80 m (square/normal to the supports). For information, the corresponding skew length would be 2 × 46189 mm (the P1–A1 span dimensioned '40000(SQ) 46189(SK)') = 92378 mm ≈ 92.38 m along the 30° skew; the drawings do not label either figure as the key-plan block length, so the square total of 80 m is quoted.The hatched key-plan block is the proposed 2×40 m MJBR named in the same proposal table, so its length is the sum of the two proposed spans. No dimension line is drawn on the key-plan hatch itself (key plan is only 1:2000), and the span figure is a centre-to-centre span rather than an overall footprint length, so confidence is low.derivedcheckp1 · p01_r01p1 · p01_r01 key plan

Worked out by anthropic/claude-opus-5 from the readings below, which are the source. A derived value shows its arithmetic — check it against the drawing before it is priced.

  "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."

  "description": "This crop shows the right-hand portion of a bridge general-arrangement sheet: the tail end of the HALF PLAN SHOWING DECK LEVEL (scale 1:300) with 30° skew, girder/bearing lines at 3500 spacing and 5000 typical crash-barrier spacing, adjoining the HALF PLAN SHOWING FOUNDATION LEVEL which shows two skewed pile caps, each 16550 wide with circular piles at 3750 centres and 775 edge distances, separated by a PCC M15 median wall and terminated by independent retaining walls. 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."
