Sediment Other Area Corrective Measure and Habitat Project Duwamish, WA

eTrac, Inc. conducted 3rd party hydrographic multibeam surveys for the Duwamish Sediment Other Area Corrective Measure and Habitat Project – Boeing Plant 2 since the project began in 2012. eTrac was contracted by Envirocon under BOEING to perform the high resolution surveys to support their dredging and capping activities on this environmental remediation project. In addition to hydrographic surveys, eTrac provided electronic sediment barge monitoring with a customized client interface web site used for asset and quantity management along with support service for the precision excavator positioning system in use on the project. This data was used for daily updates of the onboard 3-Dimensional dredging software, greatly benefiting machine efficiency while minimizing environmental impact.
