Sources Sought_2.pdf

THIS IS NOT A SOLICITATION FOR PROPOSALS. THIS IS A SOURCES SOUGHT

SYNOPSIS ONLY

This Sources Sought is for the purpose of identifying contractors that possess the capabilities outlined below. The NAICS code for this Sources Sought is 334519 and the Product Service

Code is 6655.

The Bureau of Reclamation (Reclamation) has a requirement to procure twelve (12) high fidelity accelerometers as well as twenty six (26) Dual Digitizer Split Boxes and twenty six

(26 ) ten meter ( to m) Silicon Audio to Dual Digitizer Split Box cables to monitor and record ground motions from natural and/or induced earthquakes that may impact a Reclamation facility. High fidelity accelerometers will allow 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 seismometers procured will be integrated into the existing Strong Motion

Monitoring Program Realtime Data Acquisition System.
