The NZTA Maintenance & Operations team including Journey Managers, Network Managers and Maintenance Contract Managers are working closely with our contractors and TTM suppliers to road test the risk-based approach on cyclic activities, emergency response and our processes:
We’re gearing up to move from piloting the risk-based approach to adopting it as our standard approach to TTM for specific activities on our state highways with some new contracts starting in July 2024.
In addition, the NZTA Infrastructure Delivery team are piloting the new risk-based approach on capital projects.
Pilots on the state highway network
Faster adoption of the new risk-based guidance means NZTA will retire CoPTTM by end-October 2024. This means NZTA will no longer use CoPTTM as the basis of our decision-making for TTM at worksites on our state highway network.
Locally, NZTA is working directly with Auckland Transport to help make TTM more efficient and effective on both state highways and local roads.
We’re also seeing the TTM sector adopting the new risk-based approach and there are some great examples across the country being led by our suppliers. Careful planning and consideration of safe detours, road closures, nightworks, maximising TTM resource to reduce costs and safe management of crews, vehicle movements and hazards has contributed to improving productivity.
Examples of efficient and effective TTM
From October 2024 we’ll start reporting TTM cost and performance metrics via the Road Efficiency Group (REG). The GPS directs NZTA and all other RCAs to start reporting their cost and performance metrics to show efficiency in the way transport projects are delivered.
Our Health, Safety and Wellbeing and Programme & Standards team have updated our state highway TTM assurance programme and will be trialling it over the winter in preparation to launch it in time for the 2024/25 summer maintenance season.
The NZTA auditing programme stopped at the end of the summer maintenance season (end-March 2024) and was reset to a quality assurance programme to focus on monitoring TTM plans and setups as outlined in the new guidance instead of CoPTTM.
NZTA is playing a support role to the industry-led TTM Credentials Framework working group and the TTM industry steering group (TTM ISG) to redevelop the wider sector’s training requirements – this will create an uplift in skills that the TTM sector needs to support the shift to risk-based TTM.
A new national training and competency framework has been proposed which will see all major training move to new standards endorsed by NZQA − these will be independent of NZTA.
Consultation on the proposed new TTM Credentials Framework closed on 5 April 2024.
As part of finalising the new framework, and in addition to working on a more detailed summary of the feedback received, the working group and the TTM ISG are currently looking at what additional information, support and guidance might be helpful in implementing the framework. The framework, and the training and assessment within it, is intended to continue to evolve with the needs of the TTM sector.
