Spool drawings are assembly drawings which contain comprehensive manufacturing and fabrication information for each unique “spool piece”. Piping spools are generally represented in symbolic isometric drawings. Spool drawings are produced from a BIM model in 3D representation, line representation, and symbolic form along with 2D plans, sections and isometric views. BIM can automatically assign spool assembly drawings with bill of material data.
The piping spool drawings can be utilized for accurate pre-fabrication off-site / on-site compliant with contractors’ pre-fabricating standards and preferences.
A spool drawing may contain dimensions and angles, a bill of materials, and manufacturing information.
