Freedom’s Geospatial Surveying team provided full survey support for Project Olympus,a major high-voltage cable installation linking a new East London data centre to National Grid substations. Covering approximately 20km of heavily congested streets, the project aimed to deliver a fully diverse, fail‑safe power supply.

Challenges faced

• Compressed programme with early survey outputs needed to maintain momentum across a complex project. ​

• Limited routing options with engineering constraints requiring precise positional certainty. Challenging survey environment,including narrow footways, parked vehicles, buses, and heavy traffic flows restricting survey equipment ​deployment.

• Complex coordination with multiple stakeholders due to a congested underground utility environment and need to minimise traffic disruption across central London.

Solutions delivered

• Delivered a comprehensive, verified dataset integrating topographical, PAS 128 and QLA information to timescale. ​

• Identified engineering pinch points early, ​reducing design risk. Maintained exceptional survey accuracy while reducing on‑street disruption. Combined IDS Stream UP GPR and Leica Pegasus TRK mobile mapping systems with traditional topographical and utility detection methods.

• Coordinated collaboration across department sand stakeholders. Minimised the need for traffic management on busy London highways by maximising mobile data capture.

Value delivered

The commissioned works formed part of amulti‑million‑pound design and buildcontract, delivered through closecross‑department collaboration.​

Alignment with internal design, engineering, civils, and project delivery teams ensured survey outputs were fully integrated into the wider programme. This cross‑department collaboration accelerated decision‑making,reduced rework, and strengthened delivery efficiency.​
