| The class asks for | Value | How | From |
|---|---|---|---|
| LengthLwants m/mm | not establishedThe readings are transverse cross-sections (Section at Abutment and Section at Pier) at 1:150 scale, which show width and thickness of the WC layer but do not give any longitudinal dimension (span length or total length) for the wearing course. | not found | |
| WidthWwants m/mm | 13500 mmBoth crops note the wearing coat is a layer 'over deck slab each carriageway', and the deck slab/carriageway width is explicitly dimensioned as 13500mm ('Carriageway width' = 13500, appliesTo 'Carriageway (each side)'). Since the WC is described as laid over the deck slab for each carriageway, its width is taken equal to the carriageway width it surfaces: 13500 mm.The WC width is not separately dimensioned with its own callout; it is inferred from the carriageway width it overlays, per both cross-sections. Since this is an inference (no explicit WC width dimension line), confidence is low. | derivedcheck | p3 · p03_r01 cross section of deck footpath crash barrier and pile cap at abutmentp3 · p03_r02 cross section of deck and pile cap at pier p1 |
| Layer ThicknessT_layerwants m/mm | 50 mmDirectly stated in both crops as '50mm THK. (WC)' and 'Wearing coat thickness = 50, unit mm, appliesTo WC layer'.Explicit note '50mm THK. (WC)' appears in both crops, directly labeling the wearing coat thickness with no ambiguity. | read | p3 · p03_r01 cross section of deck footpath crash barrier and pile cap at abutmentp3 · p03_r02 cross section of deck and pile cap at pier p1 |
| Material TypeMAT | Bituminous (implied) -Crop 1 object list states material for 'Wearing coat' as 'bituminous (implied)'; no explicit material spec sheet is present in the readings to confirm the exact bituminous mix type.The drawing does not explicitly name the wearing course material (e.g. 'Bituminous Concrete' or 'BC') with a labeled callout; it is inferred/implied from standard practice and the crop's own annotation of 'bituminous (implied)'. No other material note (e.g. concrete class) is given for the WC layer, distinguishing it from the RCC deck slab beneath it. | readcheck | p3 · p03_r01 cross section of deck footpath crash barrier and pile cap at abutment |
Worked out by anthropic/claude-sonnet-5 from the readings below, which are the source. A derived value shows its arithmetic — check it against the drawing before it is priced.
