What this contract is for

THIS IS A REQUEST FOR INFORMATION ONLY. THIS IS NOT A SOLICITATION. This notice is issued solely for informational and planning purposes. This notice does not constitute a solicitation. The Naval Nuclear Laboratory (NNL), operated by Fluor Marine Propulsion (FMP), is utilizing this request for information for market research to determine what organizations have the capability to fulfill this requirement. NNL will not be responsible for any costs incurred by interested parties in responding to this request for information. Responses shall not exceed five (5) pages in length. Scope: When performing maintenance on a pure water fluid system, valves are commonly used for work area isolation. Valves that have been in-service can leak past their seats. In this case, the worker may still be protected from hazardous energy on the other side of the valve but work such as welding might not be possible if water is being continually introduced to the work area. In this case, more valves can be used if available in the system design, but if not, freeze seals are commonly used to eliminate leakage. Freeze seals can consume significant work and resources to set, so alternate means to mitigate water leakage past valves is desired. A method to mitigate valve leak-by for the hours or days a system is open for maintenance or the time to perform a weld is desired which will not affect pure water chemistry or stainless-steel corrosion or cracking performance. The method must not introduce devices or materials that require removal from the system after repair is completed. Solutions must either be external to the system, completely dissolve into known and consistent constituents at room temperature, or otherwise non-intrusive.

How to bid on this

This is a contract solicitation, not a grant. To bid, you submit a proposal (usually a price and a description of how you would do the work) directly to the government, through the channel the official listing specifies, not through Oppward.

Make sure your business has an active SAM.gov registration. You cannot be paid on a federal contract without one.

This listing has no set-aside restriction ("full and open competition"), meaning any business, large or small, can bid.
Submit your proposal by the deadline, using the exact submission method the official listing states. A technically on-time bid sent the wrong way is often treated as late.
