Storage tank construction codes

This topic lists the storage tank construction codes supported by Touchstone.

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.

Construction Code Category Description
221 Underground Liquid Tanks Underground tanks that are designed to hold liquids. For the Verisk Earthquake Model for the United States, we recommend using the new 4-digit construction storage tank construction code 2211.
222 Underground Solid Tanks Underground storage tanks that are designed to hold solid material. For the Verisk Earthquake Model for the United States, we recommend using the new 4-digit storage tank construction code 2221.
223 On Ground Liquid Tanks Above ground storage tanks located on the ground surface that are designed to hold liquids. For the Verisk Earthquake Model for the United States, we recommend using the new 4-digit storage tank construction code 2231.
224 On Ground Solid Tanks Above ground storage tanks located on the ground surface that are designed to hold solid material. For the Verisk Earthquake Model for the United States, we recommend using the new 4-digit storage tank construction code 2241.
225 Elevated Liquid Tanks Above ground storage tanks located above the ground surface that are designed to hold liquids. For the Verisk Earthquake Model for the United States, we recommend using the new 4-digit storage tank construction code 2251.
226 Elevated Solid Tanks Above ground storage tanks located above the ground surface that are designed to hold solid material. For the Verisk Earthquake Model for the United States, we recommend using the new 4-digit storage tank construction code 2261.
