Topographic & contour surveys

Your deliverables

What the scope can include

• A topographic CAD plan and readable PDF showing the features included in the survey.
• Spot levels and contours at an interval agreed for the terrain and design purpose.
• Reference-point and benchmark information used for the survey.
• A terrain model, sections or point schedule where specified in the brief.

Final deliverables are confirmed in your project proposal.

Before the field visit

What to have ready

• Send a location pin and mark the survey extent, including any adjoining road or drainage connections.
• Ask your designer to specify the coordinate system, level datum and preferred file format.
• Identify priority features, the desired contour interval and any planned earthwork.
• Tell us about dense vegetation, restricted areas, traffic or access limitations.

01

Agree the detail

We define the boundaries of the survey, important features and drawing requirements.

02

Establish references

The team checks the available control and level references before detailed measurement.

03

Capture the terrain

Field work records levels, breaklines and the visible features required by the brief.

04

Build the drawing

We process and check the observations, prepare contours and hand over the agreed outputs.
