Route Surveys

When a land surveyor performs a route survey at API Survey, they collect the various degrees of data needed to design the best road possible. Roads are not the only thing that can be designed using route surveys. These surveys can be used to expand a railroad, add onto an existing pipeline, and provide utility access to more homes and businesses.

Topographical Surveys

Do you know how high the land you just purchased is? Are you sure it is all the same elevation? These are vital facts that are needed when considering building anything on land. If you are living close to a river or creek that can flood from time to time, you may want to reconsider your decision of how you want to build up your property. Knowing the features of your land can save you from making a costly mistake. Generally, a topographic survey is performed so a building site design can rely upon it for new development. API has vast experience performing topographic surveys.
