Tappan Zee Bridge Environmental Compliance Monitoring

Before construction, moved an active oyster reef by harvesting at known locations in the construction zone and relocating to an area that would remain undisturbed.

During construction, provided a variety of field monitoring for environmental compliance. Water quality monitoring, sturgeon, and underwater noise monitoring during pile driving, dredging, and other bottom disturbing activities.

At the port of Coeymans, installed underwater telemetry to position tagged fish that passed through the array.
