AIR provides the following codes for pipeline construction:

  While Coverage C (content) is not supported for most of the 200-series construction class codes, it is, supported for Inland Transit (construction code 259) and for some other construction codes, such as tanks and pipelines. For the full list of supported combinations, refer to the "Const. & Occ. Combin." tab in each model supplement.
