Bridge Model – Duval County, Florida
Arc Surveying & Mapping, Inc. was tasked by District II FDOT to perform a hydrographic and
laser scan survey of six (6) bridges in Duval County. A combination hydrographic and
topographic survey of each bridge was performed utilizing a Reson 7101 multibeam swath
sounder and an Optec ILRIS optical laser scanner. Data were merged into a 3D Polyworks
model and cad files were provided in microstation. The survey was referenced horizontally to
the Florida State Plane Coordinate System and vertically to North American Vertical Datum
(NAVD88). The maps and models developed from these surveys clearly illustrate the bridge
structure by using a combination of laser scanning and construction drawings to view the
bridge and its interface with the bathymetry. The models of these surveys were provided to
DOT in software that permits the user to move a computer cursor anywhere in the model to
obtain xyz values or take measurements. Bridge support piling, etc., were included in 3D
models including data below the seafloor. This data was acquired from FDOT construction
drawings.
Equipment Utilized:
▪Reson 7101
▪ILRIS Laser Scanner
