This is a Questions and Answers document (Amendment 002) for solicitation 140G0126Q0040 related to the CERC Well No. 1 Renovation project. The document addresses two clarifications that arose from the pre-bid meeting. First, regarding flow sensors, the document specifies that two 6-inch flow meters will be installed, with one meter on each of the two towers. Second, the document clarifies that a new non-reverse ratchet assembly will be installed onto the new motor, answering confusion about which motor component required this upgrade.

The document includes four referenced images that appear to provide visual details related to the flow meter installation and motor ratchet assembly specifications, though the specific technical details of these images are not described in the text. This Q&A clarification is part of Amendment 002 to the solicitation, which was issued to address bidder questions prior to the quote submission deadline of February 11, 2026. Interested small businesses should reference these clarifications when preparing their quotes for this $100,000–$250,000 construction renovation project at the U.S. Geological Survey's Columbia Environmental Research Center in Columbia, Missouri.
