Kissimmee River Restoration Project – Marine Mattress Survey
Okeechobee, Florida
During 2015 Arc Surveying & Mapping, Inc. (Arc) was contracted by Cajun Dredging to fulfill the
specified hydrographic and multibeam survey requirements of the contract from the
Jacksonville District, . The project consisted of surveying prefabricated concrete mats after
installation on the lake bottom to certify accurate positioning and grades. Arc surveys the mats
after placement using one of our survey vessels, a Reson 7125 multibeam system operating at
400kHz, the POS wavemaster w/IMU, and Trimble RTK for positioning and water surface
elevations. Upon survey completion of each area, usually 4-6 mats, Arc hydrographers map the
mats using a 0.1 x0.1 foot matrix grid using Microstation and Inroads to identify the mat
corners, label, and catalog them. In addition, per specifications, all gaps between maps that
exceed one foot must be identified on the maps. Arc has 24 hours to submit each map to the
Jacksonville District office, but typically deliver them within 12 hours. Arc is also performing as
built surveys of the riprap that was dropped on top of the approved mat sections.
