Freedom’s Land and Environment Services delivered comprehensive geospatial survey planning and delivery to support a major high‑voltage cable installation for Project Olympus, linking a new East London data centre to National Grid substations. The project covered approximately 20 kilometres of heavily congested urban streets and formed a critical part of delivering a fully diverse, fail‑safe power supply.

Our Geospatial Surveying team was appointed to provide full survey support across the route, operating within a challenging programme that required early survey outputs to maintain momentum across a complex, multi‑disciplinary project. Routing options were extremely limited, with tight engineering constraints demanding a high degree of positional certainty to de‑risk design and construction.

Survey delivery took place in a highly constrained urban environment, characterised by narrow footways, parked vehicles, bus routes and heavy traffic flows that restricted the deployment of traditional survey equipment. In parallel, the dense and complex underground utility environment required close coordination with multiple stakeholders, alongside a strong focus on minimising disruption across central London’s busy road network.

To address these challenges, we delivered a comprehensive, verified survey dataset integrating topographical, PAS 128 and QLA information, aligned to programme timescales. By combining IDS Stream UP ground‑penetrating radar and Leica Pegasus TRK mobile mapping technology with traditional topographical and utility detection methods, we maintained exceptional survey accuracy while significantly reducing time spent working on‑street.

Early identification of engineering pinch points allowed design risks to be addressed at an early stage, supporting informed decision‑making and reducing the likelihood of downstream change. A collaborative delivery model ensured effective coordination across departments and external stakeholders, while maximising mobile data capture reduced the need for traffic management on some of London’s busiest highways.

The commissioned works formed part of a multi‑million‑pound design and build contract, delivered through close cross‑department collaboration. Alignment between survey, design, engineering, civils and project delivery teams ensured survey outputs were fully embedded within the wider programme, accelerating decision‑making, reducing rework and strengthening overall delivery efficiency.
