An existing-infrastructure review should identify physical assets, live services, carrier handovers, contracts, capacity, resilience, support arrangements and known faults. The objective is to establish what can be reused, upgraded, rationalised or replaced before a new procurement or construction programme begins.
Start with a complete inventory
Collect current circuit schedules, carrier invoices, network diagrams, duct and chamber drawings, fibre test records, contracts, support arrangements and any known fault history. Where records are incomplete, confirm the physical position through site inspection and carrier enquiries.
- Existing ducts, chambers, fibre and building entries
- Carrier handover points, racks, power and internal containment
- Live internet, Ethernet, wavelength, dark-fibre, mobile, microwave or satellite services
- Capacity, utilisation, contract end dates and upgrade paths
- Primary and backup routes, underlying wholesale networks and common points
- Support hours, service levels, monitoring and fault procedures
Review the physical route and ownership
A service inventory alone does not show whether the physical infrastructure is usable. Establish who owns each duct or fibre section, where it runs, whether spare capacity exists and whether access rights, wayleaves or maintenance responsibilities are documented.
Test the commercial position
Record recurring charges, construction contributions, contract dates, notice periods, indexation, termination liabilities and ownership of installed apparatus. This allows the project team to distinguish a technical constraint from a contract that can be renegotiated or replaced.
Turn the findings into decisions
Retain infrastructure or services that meet the requirement.
Increase capacity or improve support on an existing route.
Remove duplicated or poor-value services.
Procure a better carrier or product.
Construct only the missing segment that the market cannot supply.
What the review should produce
The output should be a clear asset and service register, route and resilience summary, contract calendar, risk list and recommended action plan. It should distinguish confirmed evidence from assumptions that still require survey or carrier validation.
Frequently asked questions
Common questions
Can CROSS review infrastructure that was installed by several different suppliers?
Yes. The review can consolidate physical assets, live services, contracts and responsibilities into one evidence-led view.
Do we need accurate drawings before starting?
No. Existing records are useful, but gaps can be identified and prioritised for site survey, carrier enquiry or test work.
Can the review identify cost savings?
Yes. It can identify unused capacity, duplicated services, poor contract structures and routes that can be replaced or renegotiated.
Does a desktop review replace a physical survey?
No. It identifies what is known and where targeted site or route verification is required.
