AIR provides the following codes for bridge construction:

  200-series construction class codes are not applicable for coverage C.

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 for the U.S. and Canada only, 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 for the U.S. and Canada only, 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 for the U.S. and Canada only, 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 through the bridge's year built information, and the determination varies by country depending on each country's respective effective bridge design code.

 

Valid for South America only.

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.

 

Valid for South America only.

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, and the determination varies by country depending on each country's respective effective bridge design code.

 

Valid for South America only.

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, and the determination varies by country depending on each country's respective effective bridge design code.

 

Note that for single span bridges, the construction material does not matter.

 

Valid for South America only.

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, and the determination varies by country depending on each country's respective effective bridge design code.

 

Valid for South America only.

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, and the determination varies by country depending on each country's respective effective bridge design code.

 

Valid for South America only.

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, and the determination varies by country depending on each country's respective effective bridge design code.

 

Valid for South America only.

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, and the determination varies by country depending on each country's respective effective bridge design code.

 

Valid for South America only.

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.

 

Valid for South America only.
