Survey & Mapping

Our land surveying department has a reputation for tackling the most complex projects, having a commitment to technology, and providing the highest level of client engagement and service. With over seven survey crews and four licensed professional surveyors, we have the capacity to respond to urgent project issues and meet the most demanding schedules. Our responsiveness to client requests is unparalleled.

In addition to providing support for our internal staff, SDA's full-service surveying department provides topographical and boundary surveys, construction layout, subdivision plats, condominium exhibit B documents, and other typical surveying tasks.

What really sets us apart from others is our concentration in several land surveying specialties. From aeronautical surveys to layout on industrial and heavy-civil projects, we have the experience to hit the ground running.
