Designing on an existing site
Provide the ground levels and features your designer or engineer needs.
Terrain & elevations / Serving Ontario
Topographic Surveys
Understand the terrain before you design. Ground elevations, visible site features and agreed volume information for projects across Ontario.
Understand the service
What does a topographic survey show?
A topographic survey measures the shape of the land and relevant physical features within a defined area. It gives designers and engineers an existing-condition base for planning, grading and construction decisions. Where requested, Grad Surveying also uses survey measurements for material-volume calculations. The required level of detail and output format are agreed around the way your consultant will use the data.
Is this right for you?
When might you need it?
Planning grading work
Establish an existing-condition base for the next design stage.
Measuring material volumes
Discuss the pile, survey extent and reference surface for a calculation.
Define the assignment
What can the scope include?
We confirm the survey information and deliverables your assignment needs. The following items guide that discussion.
Survey extent
Agree which accessible parts of the site will be measured.
Levels and features
Capture the relevant ground elevations and visible physical features.
Survey data
Present the measurements in the agreed plan or data format.
Volume calculations
Define the reference information and reporting when volume work is requested.
Your deliverables: The agreed survey plan or data, which may include spot elevations, contours, surface information or material-volume calculations. Proposed grading design and legal boundary work must be requested separately where needed.

Frequently asked questions
Does topography confirm ownership boundaries?
Boundary work needs to be included separately when it is required.
Is a grading plan included?
A proposed grading plan is a different output. Explain whether you need existing measurements, grading work or both.
Can you calculate stockpile volumes?
Yes, material-volume work is within our topographic services. The measurement area and calculation basis need to be defined first.
