Pipeline Construction Codes

Pipeline construction codes supported by Touchstone.

AIR provides the following codes for pipeline construction:

Note:

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. For information about individual model support for the 2000-series codes, see Construction Class Codes -- 2000-Series.
