The class asks forValueHowFrom
LengthLwants m/mmnot establishedThe readings show transverse barrier/parapet profiles and an expansion-joint detail, but provide no longitudinal barrier length or bridge length from which the barrier length can be derived.not found
HeightHwants m/mmnot establishedNo dimension is identified as the height of the bridge barrier. Dimensions shown relate to deck/slab thickness, reinforcement, drip bead, chamfer, or the expansion-joint detail.not found
Instance CountNwants count2 countEach transverse slab/superstructure section explicitly shows two edge barriers/parapets, one at each outer deck edge. The two barrier segments shown in the expansion-joint detail are not used because they are segments of a single joint detail rather than the bridge-wide barrier count.readp5 · p05_r01 section thru slabp5 · p05_r05 section thru slabp5 · p05_r06 8 typ
Material TypeMATnot establishedThe barrier/parapet objects have no material stated. Reinforced concrete is identified for the deck slab in a related reading, but that material is not explicitly assigned to the barrier and cannot be assumed.not found

Worked out by openai/gpt-5.6-terra from the readings below, which are the source. A derived value shows its arithmetic — check it against the drawing before it is priced.
