LengthLwants m/mmnot establishedNo dimension owned by the median wall establishes its length; deriving it from the span lengths would attribute a neighbouring element's dimension to this item.not found
WidthWwants m/mm2900 mmCross section at abutments A1 & A2 (scale 1:150) carries the dimension 2900 across the median, listed as 'Median gap between decks — appliesTo Cantilever median wall / median opening'.2900 is the only transverse dimension associated with the cantilever median wall in the readings, but it is described as the gap/opening between the two decks, which is the space the wall sits in rather than a stated wall thickness; the wall's own thickness is not separately dimensioned. Reported as the wall's width with low confidence because of this ownership ambiguity.readcheckp3 · p03_r01
HeightHwants m/mmnot establishedNo stated vertical dimension or pair of levels belongs to the median wall; any height would have to be scaled off the 1:150 section, which is not a stated value.not found

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."

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."
