Questions and Answers Solicitation 140L4025Q0004

Project Name: Acoustic Doppler Current Profiler (ADCP) System

Item # Question Answers

1 We would like to know if this is a brand-new contract OR if there is (was) an incumbent performing these services.

Information regarding BLM contracts are publicly available

2 Will you please clarify whether or not the user wants to use GPS tracking for discharge measurement, or will they just use the ADCP’s bottom tracking utility?

No, GPS tracking is not required for this request. However, I do want the flexibility to add GPS tracking at a future date.

3 Can you please clarify if you want a GPS included in the quote that can be used for discharge measurement?

No, a GPS is not required for this quotation.
