Building information modeling (BIM) presents structural information in the form of three-dimensional (3-D) graphical representations of elements such as beams, columns, and slabs. This information may be further associated with metadata (nongraphical information) such as compressive strength, reinforcement ratio, and maximum aggregate size. It is not necessarily possible to review a modeled object and understand its accuracy or intention. Viewers of models tend to assume designs are more complete than they may actually be, partially due to highly detailed graphics. Does this object represent 10, 30, or 80% of the final design?
