BNSF Bridge Number 24.8 Replacement
Greenbusch prepared an Underwater Noise Monitoring Plan outlining means and methods for underwater noise monitoring, signal processing and reporting requirements for submission to State and Federal Agencies/Services. The project's permits require hydroacoustic monitoring for all piles driven on-land and in-water with an impact hammer. Due to the Project's duration and location, project specific equipment and deployment techniques were developed.
Underwater sound levels are monitored in real time to ensure the distances for onset of injury to fish does not exceed the distances specified in the Project's environmental permits. The data collected during these measurements is used to generate an Underwater Noise Monitoring Report summarizing the results of underwater sound levels from impact pile driving, data acquisition procedures and monitoring equipment and the predicted areas of influence on fish.
Greenbusch also provides technical expertise in mechanical engineering, audio/video consulting, mechanical engineering and commissioning services.
