Summary
HS2’s (the UK’s flagship High-speed rail project) Requirements Management and System Assurance team faced an overwhelming challenge: managing 37,983 requirement objects across 19 distinct areas and 89 modules. Managing a geographically diverse supply chain and varying processes required significant manual effort to assess contractor asset compliance throughout design, construction, and handover stages, taking up to two weeks to validate each asset.
The Challenge
Off-the-shelf AI solutions proved inadequate due to their inability to adapt to HS2’s specific requirements and complex setup processes. BuildPrompt delivered a tailored AI application that automated verification while maintaining essential human oversight, resulting in reduced cycle times, costs, and training requirements.
Process and data inconsistencyÂ
Contractors use specialised processes, forcing HS2 to accept similar but non-conformal data formats, creating review challenges.
Requirements complexity Â
38,000 requirements across 19 areas creates an overwhelming verification burden.
Data Fragmentation Â
Teams waste a significant amount of time searching for information across scattered formats.
Integration Risk Â
Non-compliant requirements can potentially impair railway functionality and system integration.
“The AI tool BuildPrompt developed processes complex spreadsheets in seconds, revealing key issues we would have missed with manual reviews.”Â
Vijay Patil, Head of Requirements, HS2
Platform Architecture
Agentic workflows Â
- Analyses thousands of HS2’s verification and validation matrix data rows simultaneouslyÂ
- Cross-references requirements using HS2-specific terminology and compliance criteriaÂ
- Creates automatic verification chains that trigger based on findings
- Identifies non-compliances using HS2’s coding structureÂ
Real-time visualisation & consolidation Â
- Colour-coding visualisation of compliance status
- Maps dependencies between assets, evidence and requirementsÂ
- Highlights critical integration risks visuallyÂ
- Shows compliance trends across portfolio, requirement and asset levels
Natural Language intelligence Â
- Natural language questions with instantly evidenced responsesÂ
- Filter by contract areas, asset types or requirement categories
- Identifies trends and insights without manual analysisÂ
- Transforms complex queries into actionable intelligence for decision-makingÂ
