Precision when it counts.

CGA deploys 12 experienced survey crews state-wide, daily.

Our licensed professionals are trained in the State of Iowa requirements and standards and comply with IDOT requirements. Surveying is an essential element in property development and is a requirement in the planning and execution of nearly every form of construction.

We have the personnel and equipment to accurately collect all of the information required for a variety of survey projects, including topographic surveys, right-of-way or easement acquisition surveys, flood studies, and more. We match our survey techniques and deliverables with the needs of each project.

Did you know?

Many people assume telephone poles, fences, or sidewalks are property corners when they most likely are not. Professional land surveyors are trained and licensed to make property line determinations. CGA surveyors can provide you with a map and a legal description of your property.
