Pipeline construction codes
The pipeline 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.
In Touchstone 2025, we added support for 2000-series codes to the Verisk Bushfire Model for Australia and the Verisk Typhoon Model for South Korea. For information about supported codes and limitations for specific models, refer to the model documentation that is available on the Client Portal.

| Construction code | Category | Description |
|---|---|---|
| 227 | Underground Pipelines | Pipelines located under the surface of the ground. For the Verisk Earthquake Model for the United States, we recommend using the new 4-digit pipeline construction code 2271. |
| 228 | At Grade Pipelines | Pipelines located at the surface of the ground. For the Verisk Earthquake Model for the United States, we recommend using the new 4-digit pipeline construction code 2281. |
| 2270 | Unknown Pipeline | Pipelines with an unknown location and material, or other unknown pipelines that cannot be mapped to any of the other pipeline construction class codes. |
| 2271 | General Underground Pipelines | Pipelines located under the surface of the ground with an unknown material of construction. |
| 2272 | Underground Cast Iron Pipelines | Pipelines located under the surface of the ground and made of cast iron material. |
