Commercial Vehicle Engineering for Body Builders & Manufacturers

ADR and ROVER approval support for Victorian manufacturers

CVC supports Victorian manufacturers and body builders with ADR applicability, engineering evidence, ROVER submissions, Vehicle Type Approval and Second Stage Manufacture planning where the project falls within the national RVS framework. Related resources: ADR Testing & Engineering Evidence, ROVER, VTA & SSM Support, Vehicle Type Approval Evidence Requirements and SSM vs State Modification Approval.

For vehicle import and market-entry programs: see CVC’s Vehicle Import Approval in Australia guide and ROVER / ADR consultant selection guide.

Commercial Vehicle Compliance (CVC) supports Victorian body builders, manufacturers, dealers and vehicle modifiers with engineering assessment, VASS certification and compliance planning for commercial vehicle projects. Our role is to help identify the approval pathway early, review the proposed design, complete the required engineering work and provide a clear route to final certification.

Support before fabrication

Many compliance problems are created before a vehicle reaches inspection. CVC can review a proposed body, chassis or equipment installation before fabrication begins so issues such as axle loads, wheelbase, rear overhang, body mounting, structural loads, clearances and approval evidence can be addressed while the design is still easy to change.

Typical commercial vehicle projects

For truck-mounted equipment specifically, see our crane, tipper, hooklift and tow-coupling engineering service.

  • Truck body fitment and body-type changes.
  • Wheelbase and chassis modifications.
  • Crane, tipper and hooklift installations.
  • Tow couplings, fifth wheels and associated mounting structures.
  • GVM, axle-load and weight-distribution assessment.
  • Bus, van and specialist vehicle modifications.
  • Seating, wheelchair-access and restraint-system changes.
  • One-off fabricated structures and repeat-build programs.

Engineering evidence

Where formal ADR testing or recognised test evidence is required, see CVC's ADR Testing & Engineering Evidence service.

Depending on the modification, CVC may prepare or review drawings, calculations, axle-load reports, material information, structural assessments, finite element analysis (FEA), inspection evidence and other technical documentation required to support the approval.

VASS and repeat-build support

For the Victorian certification pathway, see our VASS engineering and approval service. Send the vehicle type, proposed body or equipment, build stage and expected volume through the project enquiry form so CVC can review the scope.

For Victorian projects, CVC provides VASS engineering and certification across applicable light and heavy vehicle modifications. For repeat-build work, we can also help body builders standardise the information, drawings and evidence used across a vehicle configuration so future jobs can be processed more consistently.

Interstate supply from Victoria

If a vehicle built in Victoria will be sold or registered in New South Wales or Queensland, see our interstate vehicle approval planning service for Victorian body builders.

National RVS, ROVER and SSM projects

Where a project involves new-vehicle supply, Second Stage Manufacture or type approval, CVC also supports manufacturers and body builders through the Australian RVS and ROVER approval process.

Useful CVC engineering services

Discuss the job before you build it

Send CVC the proposed vehicle, body and modification details so we can identify the likely engineering and approval requirements before fabrication is committed.
