Topographic surveys and terrain models
Topographic plans for design.
- Deliverables
- A topographic plan, orthophoto, digital terrain model (DTM) and other data specified in the scope of work.
Construction surveying
Engineering surveys, setting out and as-built documentation. One-off site visits or ongoing support throughout construction.
Surveying support for construction
Surveying at every stage of construction, from establishing the survey control network and setting out axes to checking completed structures.
- Deliverables
- A survey control network, setting-out plans and verification drawings for each construction stage.
Setting out
Setting out design axes, points and elevations for earthworks, foundations and structural installation.
- Deliverables
- Marked points and setting-out drawings.
As-built surveys and documentation
We measure the actual position of completed structures and show deviations from the construction drawings.
- Deliverables
- A set of as-built drawings in the agreed format.
Earthwork volume calculations
We calculate cut and fill volumes from survey data.
- Deliverables
- Earthwork volume calculations.
Bathymetric surveys
We measure water depths and survey underwater terrain.
- Deliverables
- Underwater terrain survey data in the agreed format.
Survey monitoring
We repeat measurements of control point positions and elevations according to the monitoring programme.
- Deliverables
- Measurement tables and point displacements between monitoring cycles.
