C05a RFI QA 127EAX26Q0052.docx

This is a Request for Information (RFI) document that addresses contractor questions regarding the GAOA Blanchard Sewer Line Replacement project at Ozark St. Francis National Forest (Solicitation 127EAX26Q0052). The RFI clarifies that water used for drilling mud (slurry) operations during the directional drilling of pressure sewer lines under North Sylamore Creek must be obtained from local commercial or industrial sources rather than from the creek itself.

The underlying solicitation involves replacing a section of the Blanchard Springs Recreation Area sewer collection system, including directional drilling of pressure lines beneath North Sylamore Creek to prevent freezing and debris damage, replacement or lining of gravity lines, and optional rehabilitation of two pressure lift stations. The project is issued by the Department of Agriculture Forest Service and aims to eliminate deferred maintenance while improving system resiliency to extreme weather and flood events. Amendment 0001, posted August 19, 2026, includes this RFI Q&A document along with updated Davis-Bacon Act wage determinations and a pre-bid sign-in sheet that must be acknowledged and submitted with proposals.
