West Coast South Major Earthwork Management Strategy

There is a requirement to undertake a combination of on site aerial surveys and office based work. These include the following activities.

Survey Works

• Carry out survey planning activities including the production of RAMS documentation.

• Attend site on mutually agreed dates, taking into account of weather conditions, capture ground control points and perform UAS flights.

• Conduct a UAS and photography survey at the sites stated above.

• Post process the external UAS data to produce a photo realistic 3D surface model.

• Post process the 3D surface to produce a digital terrain model (removing vegetation and other fixed objects).

Computer Platform Works

• Upload the processed 3D survey information captured by to a DTO platform.

• Provide a new digital terrain model produced from the survey to allow clear visualisation and comparison with the previous survey within the platform.

• Attend a virtual meeting with Network Rails West Coast South Geotechnical Principal Route Engineering Team and CAM Project Management Team to discuss updates after each survey.

• Provide Network Rails West Coast South Geotechnical Route Engineering Team access to the D platform.
