See all FAQsHow do I request a survey?
Use the Request a Service form or contact our team with your site location, service requirement and intended purpose. The online form guides you through the information we need and lets you attach supporting documents.
How much does a survey cost?
Costs depend on the service, location, site conditions, complexity, travel requirements and deliverables. Request a quotation for an assessment of your requirements. We do not publish fixed prices because no two sites are the same.

Timing depends on site size, access, terrain, weather, complexity, available records and the deliverables required. A timeframe can be discussed after the scope is reviewed.

A survey provides technical information about measured positions and boundaries within its scope. Legal ownership and title validity require appropriate legal and documentary verification.
