Great Lakes Sensors

Statement of Work (SOW) / Performance Work Statement (PWS)

This Performance Work Statement (PWS) details the operational support and maintenance (O&M) activities for 26 water level observation stations in the Great Lakes, part of the National Water Level Observation Network (NWLON). The data collected is crucial for water resource management, safe navigation, hydrographic surveys, regulation, forecasting, and construction.

The contractor will be responsible for:

• Semi-Annual Inspections (SAI): Performing detailed inspections and maintenance on both water level stations and current meter stations. This includes cleaning, inspecting, and repairing components, as well as calibration of certain sensors.
• Unscheduled Repairs: Conducting timely repairs to restore operational status of station components when failures occur. This can range from simple battery replacements to more complex repairs after storm damage.
• Data Collection and Reporting: Ensuring data is collected and transmitted, and submitting various reports including monthly reports, preliminary site reports, and final documentation packages.
• Environmental Compliance: Adhering to Environmental Compliance Best Management Practices (EC-BMPs) to minimize environmental impact during fieldwork.

Performance will be evaluated based on meeting agreed-upon deadlines for maintenance and deliverables, and the overall quality of work, as detailed in the Performance Requirements Summary (PRS).

The PWS covers 26 stations located in the Great Lakes. The period of performance includes a base period and multiple option periods, extending up to May 31, 2033.

• Technical Expertise: The contractor must possess expertise in various sensor technologies (shaft angle encoders, pressure sensors, radar, meteorological sensors), data telemetry systems, and troubleshooting.
• Safety: Compliance with all applicable state and federal safety and health standards is mandatory.
• Communication: Strict adherence to communication protocols with the Contracting Officer's Representative (COR) and other relevant parties is required.
• Government Furnished Property (GFP): The contractor will be responsible for managing and utilizing GFP provided by the government.
• Asbestos Awareness: Contractors must be aware of and follow procedures regarding asbestos-containing building materials (ACBM) at certain stations.
