STRONG MOTION MONITORING PROGRAM

STRONG MOTION MONITORING EQUIPMENT

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 334513, Instruments and Related Products Manufacturing for Measuring, Displaying, and Controlling Industrial Process Variables, which has a corresponding Size standard of 750 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 ten (10) accelerographs, ten (10) accelerometers, and ten (10) digitizers for recording of ground motions from earthquakes that may impact Reclamation facilities. These recorders will enable Reclamation to quantify on-site peak ground accelerations from a seismic event providing critical information for dam managers and local engineers to determine if an immediate site inspection response protocol has to be implemented; And provide continuous recorded waveforms for assessment of structure’s natural modes, verification of numerical models, evaluation of local attenuation properties, and other applications related to the quantification of engineering properties of Reclamation facilities. The recorders procured must assimilate into the existing Strong Motion Monitoring Program Realtime Data Acquisition System.
