SPU/SDOT As-Built Drawing Requirements define how to prepare accurate, clean, clear as-built drawings incorporating all deviations from the original design. The document specifies mandatory “AS-BUILT DRAWING” stamping, cross-out rules for items not built, and readability requirements including additional blow-up details in congested areas. It details submittal schedules and formats, plus four submission options covering AutoCAD/Civil 3D, DWF, PDF, and print markups, including required layer, color, annotation, barcode, and markup tool standards.
