Bath Road, Slough Borough Council

The Topographical Survey provided a comprehensive record of all physical and constructed features along the survey extents of Bath Road and adjacent footways. This included:

• Road features such as kerb lines, footpaths, surface materials, tactile paving, road markings, and dropped kerbs.

• Street furniture, including traffic signage, lamp columns, bollards, and signal boxes.

• Manholes and inspection chambers, with visible cover levels recorded for integration with drainage and utility layouts.

• Building outlines for adjacent properties, including levels to eaves and ridgelines where visible from the public domain.

• Vegetation and trees, recorded where relevant to highway design, with measurements of trunk diameter, canopy spread, and approximate height.

Spot levels were recorded at 10m intervals and at all relevant grade changes to allow accurate modelling of road camber, footway slopes, and drainage considerations.

A detailed Underground Utility Mapping survey was carried out across the designated area to identify and locate all detectable buried services.

We used:

• Electromagnetic Location (EML) techniques to detect metallic and live cables or pipes.

• Ground Penetrating Radar (GPR) to detect non-metallic or deeper utilities.

• All traced services were physically marked on-site with spray paint and later incorporated into the composite CAD drawing.

Wherever possible, the findings were cross-checked against statutory records to validate alignment, depth, and type of services. This dual-layer approach was essential for reducing the risk of utility clashes during design and minimising disruption during construction.

To complement the physical survey data, we conducted a Desktop Search of statutory utility records. This included:

• Collation of up-to-date record drawings from water, electricity, gas, telecom, and fibre providers.

• A compiled utility pack for the client and design teams, helping to flag constraints and inform safe working practices.

• Early-stage identification of utilities that may require diversion or protection during the works.

The STATS search helped guide the on-site utility survey and provided important context to infrastructure planning in a densely serviced urban environment.

Survey Accuracy & Delivery

• All coordinates and levels were tied to the Ordnance Survey Network using RTK GNSS methods, ensuring interoperability with wider geospatial datasets.

• Final outputs were supplied in 2D AutoCAD (.DWG) and PDF formats, ready for immediate use in planning applications, design models, and contractor tender documentation.

Results & Impact

Our work at Bath Road enabled Slough Borough Council and its delivery partners to:

✅ Understand and manage complex surface and subsurface constraints
✅ Develop safe and sustainable transport infrastructure proposals
✅ Progress their project with confidence, knowing accurate spatial data was in place
