* ASCE cautions against directly comparing its grades with the Council's. Although ASCE examined largely the same categories as the Council did in 1988, there are differences worth noting. ASCE added the categories on school buildings and energy transmission and generation (in 2001), and divided the Council's "Highways" category into two categories: "roads" and "bridges," to more specifically reflect their conditions. The Council also focused on ports, inland waterways and flood-control dams in its "Water Resources" category. ASCE divided and expanded that category into "Navigable Waterways" and "Dams."
