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 eight 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 support for our internal staff, SDA has a full-service survey department that provides topographical and boundary surveys, construction layout, subdivision plats, condominium exhibit B documents, and other typical survey tasks.

What really sets us apart from others is our concentration in niche branches of the surveying field, including:

  • Airfield/Aviation Surveying
  • Commercial ALTA/ACSM Land Title Surveys
  • Industrial Surveying
  • MDOT and other Department of Transportation Surveys
  • Municipal Surveying
  • Tunnel Surveying
