STATEMENT of WORK (SoW) Technical Support for Specialized Equipment Review USGS Hydrologic Instrumentation Facility (HIF), 270 Kirkbride Lane, Tuscaloosa, AL

The U.S. Geological Survey (USGS) has a requirement for Technical Support services related to specialized hydrologic equipment, including refining requirements; reviewing shop drawings; validating complex assumptions, calculations and models; inspecting mockups; defining configurations; inspecting installation; and participating in commissioning.

BACKGROUND

The Department of Interior (DOI), USGS is building a new laboratory, the Hydrological Instrumentation Facility (HIF), on the University of Alabama Campus in Tuscaloosa. The general construction contract was awarded in late December 2021. Specialized equipment for the facility includes a 250’ tilting flume, a 350’ tow tank with 5-ton carriage and a 100’ test basin. Each of these features will be used for conducting specialized calibrations of hydrologic equipment and for conducting physical experiments.

SCOPE OF WORK

Provide services in support of the specialized equipment, to include refining requirements; reviewing shop drawings; validating complex assumptions, calculations and models; inspecting mockups; defining configurations; inspecting installation; and participating in commissioning. USGS estimates the services will require approximately 12 hours per week for the period April 2022 through December 2023.

Daily tasks include but are not limited to review RFIs and submittals, work with vendor and USGS staff to configure and commission systems, verify the successful transfer of calibration standards from the current HIF facility to the new facility. This work involves a highly specialized combination of both conceptual and practical experience with fluid mechanics and sediment transport laboratory facilities and flow measurement devices.

Review and recommend a wide variety of laboratory flumes constructed of steel, aluminum, glass, plexiglass, and PVC, including flow systems driven by pumps, head tanks sources, or conveyor belt systems for both unidirectional, bidirectional and more complicated flume systems with and without surface wavemakers.

Review and recommend of a variety of carriage systems intended for use in laboratory flumes, including towed, wheel-driven, stepper-motor gear and rack driven, and belt/chain driven propulsion systems.

Consult on calibration and analysis of current metering devices, including treatment of mean velocity calibration, frequency response analysis, angle-of-attack response, cavitation, threshold velocities, and general response to isotropic and anisotropic turbulent flows. This expertise includes a background in the development and use of mechanical current meters, electromagnetic current meters, hot wires, hot films, force-based current meters, optically based current meters of various types, and a wide variety of sensors used in flow monitoring.

Configuration of 1-, 2-, and 3-dimensional laser-Doppler velocimetry and phase-Doppler measurement techniques for the non-invasive determination particulate velocities and sizes in turbulent flows.

Consult on interfacing of flow measurement devices with computational systems for analysis and data storage across a range of techniques, including local-area networks, direct memory access, and various recording devices.

Consult on optical, photogrammetric, and video data collection techniques for fluid mechanics experiments and real-world applications, including methods of particle-tracking velocimetry (PTV), particle-image velocimetry (PIV), and surface particle-image velocimetry.

Consult on measurement and computational modeling of sediment transport in water flows, including detailed treatment of both bedload and suspended load materials.

Review related to measurement and computational prediction of the Lagrangian movement of particles in turbulent flows.

Consult on development of computational fluid dynamics (CFD) codes and their implementation in parallel with laboratory experiments for verification/calibration.

Consult on remote sensing techniques for a variety of fluid mechanical measurements including water-surface elevation, velocity, vorticity, wave properties, temperature, sediment properties, depth, bed elevation, and constituent concentration.

ADMINISTRATIVE PROCEDURES

The awardee will coordinate all meetings and site visits through the USGS Contracting Officer’s Representative (COR) or the COR’s designated alternate. All personnel, subcontractors and representatives visiting USGS sites will be required to sign in upon arrival. Each visiting individual will be required to enter his/her name, company’s name, USGS project title, date, reason for the visit, and the times of arrival and departure. Arrangements for after-normal-working-hour site visits must be made in advance during normal working hours.

DELIVERABLES

Detailed reports to document reviews and findings of work described above.
