Bridge construction codes
This topic lists the bridge 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 the "Construction class codes – 2000-series" topic in the Touchstone Exposure Data Validation Reference.
| Construction Code | Category | Description |
|---|---|---|
| 201 | Conventional - Multiple Span Bridges | Bridges having multiple simple spans with each span being less than 500 feet. These bridges may be constructed of concrete, steel, or timber. Valid only for the U.S. and Canada, but not when the peril is Severe Thunderstorm (PWX). Use in conjunction with occupancy class 300. |
| 202 | Conventional - Continuous Bridges | Bridges having continuous spans of less than 500 feet. These bridges may be constructed of concrete, steel, or timber. Valid only for the U.S. and Canada, but not when the peril is Severe Thunderstorm (PWX). Use in conjunction with occupancy class 300. |
| 203 | Major Bridges | Bridges having individual spans of 500 feet or more. These bridges may be constructed of concrete or steel. Valid only for the U.S. and Canada, but not when the peril is Severe Thunderstorm (PWX). Use in conjunction with occupancy class 300. |
| 2010 | Unknown Bridge (Non-Seismic or Seismic) | Seismically or non-seismically designed highway bridges with individual span length less than 500 feet with unknown material of construction, unknown number of spans, and unknown support conditions, or other unknown bridges that cannot be mapped to any of the other bridge construction class codes. Touchstone determines whether a bridge is seismically or non-seismically designed via the bridge's year built information; the determination varies by country depending on each country's respective effective bridge design code. |
| 2011 | Multi-Span Simply Supported (Non-Seismic or Seismic) Concrete Bridge | Seismically or non-seismically designed highway bridges constructed of concrete and consisting of multiple simply supported spans, with individual span length less than 500 feet, spanning between consecutive piers and between abutments and piers. Touchstone determines whether a bridge is seismically or non-seismically designed through the bridge's year built information, and the determination varies by country depending on each country's respective effective bridge design code. |
| 2012 | Multi-Span Simply Supported (Non-Seismic or Seismic) Steel Bridge | Seismically or non-seismically designed highway bridges constructed of steel and consisting of multiple simply supported spans, with individual span length less than 500 feet, spanning between consecutive piers and between abutments and piers. Touchstone determines whether a bridge is seismically or non-seismically designed through the bridge's year built information; the determination varies by country depending on each country's respective effective bridge design code. |
| 2013 | Single Span (Non-Seismic or Seismic) Bridge | Seismically or non-seismically designed highway bridges constructed of steel or concrete and with a single span less than 500 feet spanning between abutments without intermediate piers. Touchstone determines whether a bridge is seismically or non-seismically designed through the bridge's year built information; the determination varies by country depending on each country's respective effective bridge design code. For single-span bridges, the construction material does not matter. |
| 2015 | General Concrete (Non-Seismic or Seismic) Bridge | Seismically or non-seismically designed highway bridges constructed of concrete with individual span length less than 500 feet, unknown number of spans, and unknown support conditions. Touchstone determines whether a bridge is seismically or non-seismically designed through the bridge's year built information; the determination varies by country depending on each country's respective effective bridge design code. |
| 2016 | General Steel (Non-Seismic or Seismic) Bridge | Seismically or non-seismically designed highway bridges constructed of steel with individual span length less than 500 feet, unknown number of spans, and unknown support conditions. Touchstone determines whether a bridge is seismically or non-seismically designed through the bridge's year built information; the determination varies by country depending on each country's respective effective bridge design code. |
| 2021 | Multi-Span Continuous (Non-Seismic or Seismic) Concrete Bridge | Seismically or non-seismically designed highway bridges constructed of concrete and consisting of multiple continuously supported spans, with individual span length less than 500 feet, spanning between consecutive piers and between abutments and piers. Touchstone determines whether a bridge is seismically or non-seismically designed through the bridge's year built information; the determination varies by country depending on each country's respective effective bridge design code. |
| 2022 | Multi-Span Continuous (Non-Seismic or Seismic) Steel Bridge | Seismically or non-seismically designed highway bridges constructed of steel and consisting of multiple continuously supported spans, with individual span length less than 500 feet, spanning between consecutive piers and between abutments and piers. Touchstone determines whether a bridge is seismically or non-seismically designed through the bridge's year built information; the determination varies by country depending on each country's respective effective bridge design code. |
| 2031 | Major Bridge (Non-Seismic or Seismic) | Seismically or non-seismically designed multiple simply supported or continuously supported bridges of steel or concrete with individual span lengths more than 500 feet. Iconic bridges are also included in this category. Touchstone determines whether a bridge is seismically or non-seismically designed through the bridge's year built information, and the determination varies by country depending on each country's respective effective bridge design code. |
