Statement of Work (SOW)

1.0 General

1.1 Background

The mission of the National Park Service is to maintain resources unimpaired for future generations. A mission of Glacier Bay National Park is to be a source of scientific investigation into the retreat of Glaciers within Glacier Bay. This service acquisition provides the maintenance on a key piece of equipment that provides reference condition information for multiple studies and serves as a data provision for a key NWLON (National Water Level Observation Network) gap within the larger Alaskan NWLON network.

Glacier Bay National Park and the National Oceanic and Atmospheric Administration developed a 5-year agreement to install a NOAA tide station at the Bartlett Cove Fuel Dock in Glacier Bay National Park. As a part of the Agreement the National Park Service agreed to ensure maintenance of the instrumentation was conducted to maintain the station to NOAA NWLON standards and ensure that the data was made available to NOAA. To accomplish this task the NPS has decided to pursue a maintenance agreement with an appropriate entity capable of providing tide station maintenance, ensuring data availability, and providing a backup assessment of tidal data through reflectometry analysis from the associated permanent GNSS fixture at the site.

1.2 Objective

The objective of this service contract is to provide appropriate maintenance, ensure public data availability, and assess and evaluate the operational performance of the NWLON station installed at the docks near the headquarters of Glacier Bay National Park in Glacier Bay.

1.3 Scope of Work

This scope of work requires that the contractor provide personnel, expertise, equipment (except GFE), supplies, transportation, tools, materials, travel, and other non-personal services necessary to operate and maintain the Glacier Bay tidal stations. The maintenance terms are defined below. All activities under this task shall be done in accordance with (1) NWLON standards as specified in the latest published copy of the Standing Project Instructions (SPI) for the Coastal and Great Lakes Water Level Stations.

The water level sensors deployed at the station are required to operate continuously.

The GLBA tidal station consists of a Radar water level measurement system that is installed with a clear, unobstructed view of the water surface. There is a GOES satellite antenna for data transmission. Also included are a GNSS antenna, and data transmission and storage devices.

Scheduled maintenance station visits are covered by this SOW:

● Scheduled Maintenance (SM) – Activities performed on an annual basis at each station to maintain system integrity and confirm vertical stability.

The Contractor shall comply with all applicable state and Federal safety and health standards and regulations applicable to this work, including, but not limited to, the Occupational Safety and Health Act, 29 U.S.C § 651 et seq. When the Contractor relies on subcontractors in executing this work, the Contractor has sole responsibility for ensuring the subcontractors are qualified, appropriately trained and outfitted, and that the subcontractors comply with all applicable safety and health standards and regulations.

The Contractor shall adhere to the delivery schedule for SM and deliverables specified in this SOW and as confirmed during the scheduling planning meeting. Any changes or modifications to the schedule for any type of maintenance visit or deliverable must be reviewed and agreed to in advance by the Government.

If a station experiences an equipment failure within 72 hours immediately following any type of Contractor maintenance visit, and this failure is attributed to the Contractor’s performance, the Contractor shall be responsible for returning to the station and remedying the issue at the Contractor’s expense.

If, upon arrival at the site, the Contractor discovers any issue, failure, damage or situation that might lie outside the scope listed in this document, the Contractor shall immediately notify COR. The COR and the Contractor will attempt to make a joint determination of the situation. Depending on the circumstances, the COR may request a resource estimate for the Contractor to perform additional work if warranted. The CO will issue any final decision regarding the plan to proceed.

Contractor shall ensure that data being collected by the Tide station are transmitted and made publicly available to ensure NPS and NOAA CO-OPS both have access to the data in as close to real time as possible.

Contractor shall take data from the GNSS antenna (CORS site GLBX https://www.ngs.noaa.gov/cgi-cors/corsage.prl?site=GLBX) and assess the efficacy of using it for reflectometry for tidal heights and water levels of the station. The GNSS and tidal station data will be compared to determine the accuracy of the GNSS reflectometry information relative to known tidal heights.
