There are three ways in which a Heavy Vehicle Certifying Engineer (HVCE) becomes involved in the certification of heavy vehicles
A Transport Services Delivery Agent (TSDA) finds something that needs to be repaired on a heavy vehicle during a Certificate of Fitness (CoF) inspection. They will issue the owner with a notice outlining where the repair is required, and request a completed LT400 form for the certification of the completed repair. It is then up to the vehicle owner to find and select a suitable repairer to undertake the repair work and a Heavy Vehicle Certifying Engineer to issue an LT400 to certify the completed repair.
The owner of a heavy vehicle or the Transport Services Delivery Agent (TSDA) finds something requiring certification or recertification on the vehicle. A Heavy Vehicle Certifying Engineer is then needed to certify/recertify the component as compliant with required standards. This may involve recommending steps that need to be taken in order for certification/recertification to be completed and a new LT400 produced.
3. Design and Modification
The owner of a heavy vehicle wishes to have modifications undertaken, or to design new components for their vehicle which change part, or all, of the structure or layout of their vehicle. The vehicle owner needs a Transport Engineer/Company to undertake the work and a Heavy Vehicle Certifying Engineer to oversee the work.
Steps in Heavy Vehicle Certification
- The certifying engineer must conduct a visual inspection of the vehicle BEFORE any structural work has been undertaken. They will take measurements, draw a sketch, record the owner’s details, and often take photographs during this inspection, and consider the task from a professional perspective
- They will then conduct necessary calculations, analysis and research to determine what needs to be, and/or can be done
- They will provide design instructions, drawings and specifications to the transport engineer/company to undertake the repairs/modifications within required safety standards and rules
- They will often inspect the vehicle whilst the work is in progress
- The certifying engineer MUST PERSONALLY reinspect the vehicle and alterations AFTER completion of the repairs/modifications to ensure that the work was undertaken to the specifications and standards required
- When satisfied with the work that has been undertaken, he/she will issue an LT400 which certifies the repair/modification as being complete and up to required standards.
- The LT400 may be issued to the owner to present to a heavy vehicle testing station for uploading into the NZ Transport Agency Landata computer records system, or the certifying engineer will upload this information to Landata themselves. A copy will be given to to the owner, and also to the testing station where appropriate
- The owner may deal directly with the certifying engineer, or a repair agent may contact the certifying engineer on behalf of their client. (Note: Some vehicle manufacturers have their own certifying engineers)
