Understand the service

What is a monitoring survey?

Monitoring surveys compare measurements collected at different times against an established reference. A useful monitoring program starts with a baseline and defines what will be observed, how often measurements will be taken and who will assess the results. Grad Surveying provides survey observations to support the requirements set by your project professionals.

Frequently asked questions

Is monitoring always continuous?

No. A program may use scheduled visits. Any automated or continuous system must be separately specified.

Who decides whether movement is acceptable?

The responsible project professionals set the assessment criteria. Surveying provides the measurement information for that review.

Can monitoring start after construction begins?

Explain the current stage. Available baseline information and site conditions affect how the assignment can be defined.
