Distributed Acoustic Sensing Interrogator Unit

Type: Sources Sought

1. Notice

This is not a solicitation but rather a Sources Sought Synopsis to determine potential sources for information and planning purposes only.

1.1 The purpose of this Sources Sought is to conduct market research to determine if responsible sources exist, to assist in determining if this effort can be competitive and/or a total Small Business Set-Aside. The proposed North American Industry Classification Systems (NAICS) Code is 541715, Research and Development in the Physical, Engineering, and Life Sciences, which has a corresponding Size standard of 1000 employees. The Government will use this information to determine the best acquisition strategy for this procurement. The Government is interested in all small businesses to include 8(a), Service-Disabled Veteran-Owned, Hubzone, and Women-Owned small business concerns. The government requests that interested parties respond to this notice if applicable and identify your small business status to the identified NAICS code. Additionally, please provide any anticipated teaming arrangements and delineate between the work that will be accomplished by the prime and the work accomplished by the teaming partners.

2. Description

The Bureau of Reclamation has a requirement to procure a Distributed Acoustic Sensing (DAS) Interrogator Unit (IU) in support of an ongoing and future project work, including additional DAS data collection using fiber optic cable already installed at Granby Dike No. 3.

This project will include the acquisition of the aforementioned IU hardware, along with an extended warranty, extended annual firmware upgrade package and extended annual support package with after sales support and software maintenance. The IU is intended to be deployed in various configurations at a variety of Reclamation facilities for providing state-of-the art sensing and infrastructure monitoring data collection in direct support of Reclamation’s Mission and to help ensure public safety. Some use applications for the IU will include active and passive engineering seismic imaging and monitoring surveys, earthquake seismology analysis, structural health monitoring of earthen embankments and linear structures (e.g., siphons, pipelines, and canals), and pipeline leak detection and localization.
