The class asks forValueHowFrom
LengthLwants m/mmnot establishedThe launching apron appears in the 1:300 longitudinal elevation only as a leader-line callout 'LAUNCHING APRON' at the embankment toe on both approaches. No dimension line, no plan view and no schedule in these crops gives an apron length; all dimensioned values on the elevation belong to spans, bearings, pile caps, piles, approach slab, PCC course or filter media. Nothing can be honestly derived.not found
WidthWwants m/mmnot establishedNo width dimension is annotated to the apron in either reading of the elevation. The only 'width' figures present (12300, 5100) are explicitly labelled as pile cap widths for A1, A2 and P1 and must not be transferred to the apron.not found
Layer ThicknessT_layerwants m/mmnot establishedNo thickness is stated for the launching apron. The thickness values on this sheet are owned by other items: 300 THK. approach slab, 150 THK. PCC levelling course and 600 THK. filter media behind the retaining walls; none of these is the apron's layer thickness.not found
VolumeVwants m3not establishedNo quantities table or BOQ line for the launching apron appears in these crops, and the geometric inputs are all missing, so the volume cannot be read or derived.not found
Material TypeMATstone / concrete blocks (apron material not printed on drawing) -Crop bridge_deck_piers_and_abutments_p02_r02 records the launching apron object with material 'stone/concrete blocks'; the second reading of the same elevation records the material field as blank.The only printed text against this item is the bare callout 'LAUNCHING APRON'; the material is an attribution in one reading of the elevation and is left empty in the other, and the notes block (concrete grades) is cut off at the crop edge. Adjacent slope protection is called STONE PITCHING, which is consistent with a stone/block apron, but the drawing does not state the apron material outright, so confidence is low and the value should be confirmed against the protection-works detail or specification.readcheckp2 · p02_r02p2 · p02_r02 elevation of bridge deck piers and abutments bridge at ch 64 412

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."

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."
