What this class covers
ANZSIC class 3101 classifies Australian businesses primarily engaged in the construction, repair, and management of road infrastructure and bridges. This includes both new construction projects and general maintenance activities on existing infrastructure. The classification applies to contractors who undertake these activities directly as well as those who manage or organise these construction projects.
Typical businesses in this class include road construction companies working on highway upgrades, bridge building specialists, firms specializing in aerodrome runway construction, asphalt surfacing contractors, and companies that maintain and repair road surfaces. These operations involve heavy civil engineering techniques and typically require specialized equipment and qualified personnel.
This classification is used by government agencies, researchers, and statistical organisations to track activity in the civil construction sector. Businesses may encounter this code when registering for an ABN, completing statistical forms for the Australian Bureau of Statistics, or when dealing with industry-specific regulations and reporting requirements.
Primary activities in plain English
Businesses in this class typically engage in one or more of the following activities:
- Building new roads, highways, and elevated road structures
- Constructing bridges, overpasses, and pedestrian bridges (including using prefabricated components)
- Building and maintaining aerodrome runways for airports
- Constructing parking areas including asphalt laying, grading, and drainage (excluding building structures)
- Applying asphalt and other surfacing materials to road surfaces
- Repairing and maintaining existing roads and bridges, including pothole repair and resurfacing
- Road sealing and surface treatment operations
Exclusions and nearby codes
Certain activities are specifically excluded from ANZSIC 3101 and are classified elsewhere:
- Manufacturing bituminous surfacing materials (except hot-mix bituminous paving) falls under ANZSIC 1709: Other Petroleum and Coal Product Manufacturing
- Tunnel construction for any purpose is classified in ANZSIC 3109: Other Heavy and Civil Engineering Construction
- Specialized trade services such as constructing kerbs and gutters only, or installing electrical wiring for traffic lights, generally fall under appropriate classes in Subdivision 32: Construction Services
Businesses engaged in related but distinct activities should consult these other classifications to ensure correct coding.
Practical guidance
When registering your business or updating your ABN details, you may need to select ANZSIC codes that best describe your primary activities. For road and bridge construction businesses, ANZSIC 3101 is typically the appropriate classification if this represents your main revenue source.
This classification may affect your workers' compensation insurance premiums, as different construction activities carry varying risk profiles. Check with your state's workers' compensation authority for specific classification requirements.
Some government grants, tenders, or industry programs may reference ANZSIC codes for eligibility criteria. Maintaining accurate classification can ensure your business qualifies for relevant opportunities in the civil construction sector.
The related BIC code 31010 may be used in additional business reporting contexts. Keep records of your primary activities as classification may be verified through business activity statements or other regulatory reporting.
