London Underground Technical Specifications

Approach / Solution

• System Baseline Review
  • Reviewed the existing telecommunications system design and identified the key assets and functions requiring specification.
  • Assessed how the current network architecture, management systems, PA/VA, and CCTV arrangements operated in practice so that replacement requirements remained aligned with the live environment.
  • Defined the intended next-generation like-for-like scope while preserving operational intent and compatibility.
• Standards, Regulations & Compliance Alignment
  • Assessed the applicable London Underground standards, together with relevant BS/EN and ISO requirements, to identify any mandatory changes, best-practice updates, or new compliance considerations.
  • Incorporated current standards, regulations, and guidance into the specification so that suppliers would be pricing against an up-to-date technical baseline.
  • Balanced legacy design constraints with modern compliance expectations to ensure the specification was both realistic and future-ready.
• Technical Specification Development
  • Wrote the technical specifications for the telecommunications works package in a form suitable for tender release.
  • Defined requirements for network switches and routers, the central management system, PA/VA, and CCTV, ensuring that technical expectations were clear, measurable, and relevant.
  • Structured the specifications to support accurate bid submission while avoiding unnecessarily vendor-specific or competition-limiting requirements.
• Tender Support & Approval
  • Produced a specification set capable of supporting supplier understanding, bid comparability, and procurement confidence.
  • Worked through the required review and assurance process with London Underground to secure approval.
  • Delivered a final set of technical specifications signed off by London Underground for tender issue.

• Delivered a complete set of London Underground-approved technical specifications for telecommunications asset renewal.
• Enabled London Underground to issue the works package for tender with a clear and defensible technical baseline.
• Improved the likelihood of accurate supplier bids by clearly defining scope, performance expectations, and standards requirements.
• Maintained competitive tension by avoiding unnecessarily restrictive requirements while still protecting technical quality and compliance.
• Ensured that next-generation like-for-like replacements could be specified in a way that accounted for both the existing design and current best-practice requirements.
