Quality Assurance Audits

Case Study: DB ESG SmartFleet QA Audit Solution for Deep Tube Upgrade Programme

Client: DB ESG

Project: TfL Deep Tube Upgrade Programme QA Auditing

Solution: SmartFleet Railway Workshop Audit

The Challenge

When DB ESG was selected to provide quality assurance auditing for Transport for London's ambitious Deep Tube Upgrade Programme (DTUP), they faced an unprecedented challenge. The programme encompasses the modernisation of four major Underground lines – Piccadilly, Bakerloo, Central, and Waterloo & City – introducing new rolling stock, upgrading signalling systems, and significantly increasing capacity.

The scale was immense:

  • Multiple manufacturing sites requiring simultaneous oversight
  • Complex infrastructure upgrades at Northfields and Cockfosters depots
  • Stringent safety requirements for increased service frequencies (from 24 to 33 trains per hour)
  • Coordination across numerous contractors and suppliers
  • Regulatory compliance demands requiring comprehensive documentation

Traditional paper-based audit processes would be overwhelmed by the programme's complexity, risking delays, inconsistencies, and compliance gaps that could impact the entire modernisation timeline.

The Solution

DB ESG implemented ExcelWraps' SmartFleet QA Audit solution to digitise and streamline their entire quality assurance operation across the Deep Tube programme. The cloud-based platform provided a unified system for managing audits across all workstreams, locations, and phases of the project.

Key Implementation Features:

ImageGrid Technology

  • Interactive visual mapping of train components, depot layouts, and infrastructure elements
  • Point-and-click functionality for raising issues precisely where they occur
  • Heat map overlays showing risk concentrations, remediation timelines, and cost impacts
  • Instant pattern recognition across multiple audit areas and manufacturing sites

Comment Bank System

  • Pre-configured database of 600+ DTUP-specific findings organised by category
  • Standardised terminology eliminating inconsistencies across audit teams
  • 20 trackable parameters per comment including risk level, cost impact, and resolution timeframe
  • Two-tier selection process reducing documentation time by 70%

Scheduled KPI Reporting

  • Automated weekly KPI snapshots tracking programme-wide quality metrics
  • Customised dashboards for different stakeholder levels (TfL, contractors, DB ESG management)
  • Trend analysis showing performance evolution across the programme lifecycle
  • Real-time alerts when metrics fall outside acceptable thresholds

PDF Document Packs

  • Automated compilation of comprehensive audit reports for regulatory submissions
  • Professional, branded documentation for TfL milestone reviews
  • Complete audit trails packaged for handover at each programme phase
  • Secure digital delivery to multiple stakeholders with receipt confirmation

The Future

As the Deep Tube Upgrade Programme progresses toward its 2035 completion target, DB ESG continues to leverage SmartFleet's capabilities. The accumulated data provides invaluable insights for future London Underground modernisation projects, while the digital audit trails ensure comprehensive handover documentation for each completed phase.

The success of this implementation has positioned DB ESG as a leader in digital quality assurance for major rail infrastructure programmes, demonstrating how technology can transform traditional auditing into a strategic advantage.
