2. The "Reference vs. Explode" Rule
The best practice to avoid liability is to never explode the standard details. Instead, reference the official NJDOT DGN or PDF as an XREF background. If you explode and modify a standard detail, you assume professional liability for the design change. By referencing the original, you prove you followed the standard as published.
C. Cross-Reference with Specifications
- Example: Detail SD-201.1 must be read with Subsection 201 (Pavement) and 301 (Aggregate Base).
D. CAD Users: Use the Official DWG/DGN Files
NJDOT provides vector files (DWG, DGN) for many details. The “best” practice is to x-ref those files rather than redraw. This eliminates drafting errors.
