Topographical Surveyor (Homebased Retainer)

Dutystation: Home based

Functional responsibilities

The Topographical Surveyor will be responsible for the following tasks:

1. Survey Planning and Reconnaissance:

• Review background documentation, existing maps, and satellite imagery before mobilization.

• Coordinate with Project Managers and Technical Teams to define survey objectives, priorities, and technical requirements.

• Prepare and submit a fieldwork plan outlining methods, schedule and risk controls.

• Work with Project Managers to secure necessary permits or access permissions.

• Conduct initial site inspections to assess terrain features, access constraints, and health and safety risks.

2. Data Acquisition:

• Use suitable methods and calibrated equipment to collect accurate data, including:

-Elevation data via Global Navigation Satellite System (GNSS), Total Station, Real-Time Kinematic Global Positioning System (RTK GPS), or equivalent tools
- Horizontal control points for accurate georeferencing
- Legal boundaries, property demarcations, and cadastral features
- Existing structures, infrastructure, and visible or known utilities
- Natural features, vegetation, and watercourses.

• Comply with all site safety protocols and use appropriate personal protective equipment.

• Identify and manage hazards related to terrain, weather, traffic, and utilities

3. Data Processing and Analysis:

• Process field data using approved software tools to generate:

- Contour maps at appropriate intervals.
- Horizontal layout plans.
- Longitudinal and cross-sectional profiles.
- Digital Terrain Models (DTMs) and 3D terrain visualizations.

• Ensure internal quality control and data integrity checks are applied

4. Reporting and Interpretation:

• Prepare clear and comprehensive reports including:

- Description of methods, equipment used, and coordinate systems.
- Summary of data accuracy, limitations, and confidence levels.
- Interpretation of findings with design and construction implications.
- Recommendations for follow-up or clarification where needed
- Supporting annexes: photographs, contour maps, layouts, cross-sections, DTMs, 3D models, and any as-built overlays.


5. Data Management and Delivery:

• Submit all data and deliverables in accordance with project timelines and formats.

• Ensure compatibility with Computer-Aided Design (CAD), Building Information Modelling (BIM), and Geographic Information System (GIS) platforms used by the design team.

• Maintain an organized archive of raw data, processed files, and field notes.

6. Additional Technical Support:

• Provide as-built surveys to verify construction against original designs.

• Support construction layout and setting-out tasks when requested.

• Assist in cut-and-fill or volume calculations for earthworks when requested.

• Contribute to design reviews by providing insights on site-specific topography constraints.

Impact of Results:

The Topographical Surveyor will be expected to provide:

• Topo-survey maps, with appropriate scales, projections, and formats.

• Digital Terrain Models (DTMs), submitted in the required format and resolution.

• Comprehensive survey reports, detailing methodology, findings, and analysis.

• As-built Drawings, documenting completed works against surveyed data.
