What this service is designed to solve
Topographic surveys provide the base information used by architects, civil engineers, infrastructure designers and contractors to understand existing ground conditions before design, grading, roads, drainage or construction. Our survey scope can be tailored from a small plot to long corridors and large development sites.
Typical scope and deliverables
Field-to-office workflow
Define the survey specification
Confirm limits, control, coordinate system, required accuracy, feature list, deliverables and site constraints.
Capture and check
Use the appropriate survey instrument mix, perform control and closure checks, and document field observations.
Process, QA and deliver
Transform observations into clean engineering outputs with naming, layers, metadata and quality checks suitable for the agreed use.
Frequently asked questions
What accuracy can a topographic survey achieve?
Accuracy depends on control, equipment, observation method, site conditions and the project specification. We agree the accuracy requirement before mobilization and select the workflow accordingly.
Can you work from my KMZ or CAD boundary?
Yes. A KMZ/KML, CAD boundary, coordinates or marked-up plan can be used to define the survey extent. We can also review the coordinate system and required datum before fieldwork.
Can you provide contours for Civil 3D?
Yes. We can provide contours and terrain surfaces in formats suitable for Civil 3D workflows, together with point and breakline data as agreed.
