The following criteria cover the design requirements and load capacity assessment requirements for new and existing bridges.

Volume 1: Design criteria for bridges and other structures

This criteria covers design requirements for bridges, tunnels, large signs and other road-related structures to ensure they are functional, robust, durable and safe. It defines procedures and provides the technical criteria required to design new structures and to widen and strengthen existing bridges for service life and durability.

Volume 2: Tier 1 Bridge heavy load assessment criteria

This criteria covers the requirements for analysing bridges and assessing their capacities to carry specific load cases (i.e. heavy vehicles). It is based on the Australian Standard AS 5100.

Volume 3: Level 3 Inspection Criteria for Potentially Structurally Deficient Bridges

This criteria covers a “Level 3 Inspection” when the Tier 1 Assessment identifies a Potentially Structurally Deficient Bridge (PSDB) for freight vehicles (as-of-right MCVs). The focus of this Level 3 Inspection is to determine if the defect is the same as the potential structural deficiency identified in the calculations.

Volume 4: Tier 2 assessment criteria

This criteria will be available shortly.  It will provide an assessment process undertaken when a Tier 1 assessment indicates that a bridge has a theoretical structural deficiency and the calculated deficiency is not confirmed by a bridge inspection. 

Annexures:

The following annexures should be read in conjunction with the criteria listed above.

Annexure S01: Frame models of complete bridge structures for tier 1 assessments 
Annexure S02: Modelling deck unit bridge superstructures for tier 1 assessments 
Annexure S03: Tier 1 assessment of shear in concrete short span bridges to AS 5100 and AS 3600 
Annexure S04: Tier 2 assessment of shear in concrete short span bridges
