Minor culvert work (RCP < 600 mm dia only no more than 2 bays) and reinforced concrete works. Roadside furniture (e.g. signs, safety barriers). Non-complex worksite traffic management. Typically AADT<100 vehicles/day. Nil Nil Non-complex project management. Low level environmental management. No to low cultural heritage. Majority of work in previously disturbed ground within road footprint.

Compliance with project specific environmental approvals from the relevant state of federal agencies (eg. EPBC). R5 R4 activities plus majority of the following: Complex grade separated interchanges, multiple carriageways. Motorway on a new urban alignment. Construction of zonal embankments. Earthworks within 2m of tidal areas. Aggressive unsuitable materials including acid sulphate soils. Slipform, concrete pavements. Permanent variable message signs and complex ITS arrangements. Complex staged traffic management in high speed &/or urban environments. Multiple alignment changes. Typically vehicles/day. Complex consultant team coordination and/or management. More complex community/ stakeholder interfaces and complex project management. Complex design management. Specific elements in design to meet environmental expectations (for example, fauna pass etc.).
of the following: Complex geometric/aesthetic shapes. Balanced cantilever construction. Major cable stayed structures. Construction over water using coffer dams or large floating cranes and launching trusses for placement of girders. Structures constructed using top down methodology. Incremental launched structures. Difficult installation conditions, including poured insitu piles in wet conditions. Pile installation from floating equipment. Staged construction in highly urbanised environment. Complex bridge widening or staged bridge construction (one lane at a time). More complex consultant team coordination and/or management. Complex design management. Complex environmental management, working near ecologically sensitive marine environment, navigational waterways. Note: Fabricated overhead sign gantries are not classified as bridgeworks for the purposes of this prequalification system. However, Participating Agencies may require companies fabricating / erecting these gantries to be prequalified at a minimum level of B1.
