We are encouraging contractors, suppliers and stakeholders to propose changes to our standards.
Standards are the detailed requirements that underpin how the railway and the delivery of improvement projects are run. The changes are to encourage greater innovation, cost efficiency and third party funding into the rail network, whilst maintaining safety.
We have already updated and streamlined many of our standards to reduce both complexity and cost, and to encourage innovation. Suppliers and other stakeholders can also proactively suggest better ways of maintaining and enhancing the railway via our standards challenge process.
Standards exist to ensure Britain has a safe, high performing and cost efficient railway, but they are often seen as overly complex and adding unnecessary cost. Our response to the Hansford Review identified a number of opportunities to address this by encouraging suppliers and other stakeholders to proactively challenge standards to increase innovation and creativity, and propose more cost effective solutions.
We've adopted a collaborative and iterative approach in developing the new standards challenge process in partnership with the Railway Industry Association (RIA) and a number of key suppliers and stakeholders.
As part of the process, suppliers and other stakeholders can now submit a standards challenge application when they consider the standard to be incorrect, not enable the application of best practice, or drive increased cost without comparable benefit. We will review all challenges received, and conduct a rigorous impact assessment across a broad range of output capabilities such as safety, performance, environment and compatibility to make sure the capabilities are not compromised.
Following the launch of the process, we have introduced a series of incentives to encourage challenges. These include:
- Providing our corporate recognition of successful applications through jointly authored and promoted case studies
- Including a category for innovation and standards challenge and innovation in industry awards
- Seeking suppliers to identify potential standards that could be challenged within tender returns
- Assessing ongoing contract performance in relation to standards challenge and innovation
- Enabling suppliers and other parties to introduce innovative approaches/products to the industry following a successful application
As the scope covers Network Rail’s whole portfolio of policies, standards, processes and specifications, including initiating dialogue with the Rail Safety and Standards Board (RSSB) in relation to Railway Group and Industry Standards, there’s excitement to see what limitations can unanimously be removed and the opportunities that will be enabled through successful challenges.
We have updated our 400 most critical standards but to ensure they always represent current best practice and constantly strive to safely reduce the cost of the railway, we need the help of our wider industry partners as well as experts from other industries and universities. The launch of the standards challenge process is the lever for this, providing genuine recognition and incentives to propose more efficient ways of both enhancing and maintaining our railway.Jon Shaw, chief engineer at Network Rail
Challenges received so far
As of March 2020, we’ve received 106 challenges where contractors, suppliers and other stakeholders tell us they can improve current best practice, and safely reduce the cost of running the railway. In addition to the 400 most critical standards we’ve updated already, we’ve opened ourselves up for other standards to be challenged if better ways of maintaining and enhancing the railway can be suggested. So far, the challenges received relate to buildings & civils (38), track (23), electrical power (21), projects (6), quality, safety, health & environment (5), Network Rail assurance panel (3), signalling electrical power (2), signalling (2), plant (1), maintenance (1), operations (1) and information management (1). You can download a more technical and detailed list of the standards challenged to date from our downloads for third parties page.
We are reviewing all challenges received, and will conduct a rigorous impact assessment to make sure safety, performance, compatibility and the environment are not compromised. Of the challenges received to date, over 50 have resulted in agreement be reached with the standard owner to modify the standard, and a number of the other challenges are currently being evaluated.
An example challenge: British Steel
British Steel has challenged some designs of our overhead line masts. They believe our current design standards mean some masts are fabrication intensive, use higher cost products and require structural steel not currently produced or stocked in the UK.
We’re evaluating and progressing their challenge through a series of collaborative workshops. The potential benefits their challenge proposes include:
- UK economic boost, helping increase our UK-sourced steel to over 97 per cent
- Locally sourced materials, reduced lead time, reduced carbon footprint
- Lower manufacturing cost
- Lower material cost
- Lower transportation cost
- Potential for up to 50 per cent cost saving for certain designs
Our rail and construction teams have formed a close working relationship with Network Rail, who’ve an excellent record of supporting UK manufacturing. By working in partnership, and accepting challenges like this, we hope to make it easier for Network Rail to source more high quality, cost effective products manufactured in the UK.John Austin, account manager, British Steel
