Arc Surveying & Mapping, Inc. has over thirty years of experience providing the Department of Transportation, bridge engineers, designers and contractors with precise above and below water surveys of bridges throughout the Southeast and Midwest portions of the United States.

Over ten years ago, DOT and Arc Surveying & Mapping, Inc. Surveyors developed a strategy to precisely observe and monitor the underwater scour of sediments from around bridge support structures, often referred to by DOT as “Unknown Foundations”.  Together Arc Surveying & Mapping, Inc. and DOT formulated an innovative plan that provided a method of identifying scour and by periodic monitoring scour quantity rates were identified using isopachs.  For details click here.
