About this file
This is a Questions and Answers document for federal contract opportunity 1232SA26Q0470, issued by USDA as of 30 April 2026.
The Q&A addresses technical and logistical requirements for piping installation and testing work. Key technical clarifications include: slip fittings are allowed on new piping; prefabricated piping can be hydrotested at the fabrication shop with additional system hydrotesting by USDA staff after installation; and X-ray radiography testing is required for welds on shop-created prefabs but not for field welds associated with slip flanges. Regarding project execution, each vault will be processed individually with 8-hour shutdowns during normal working hours (approximately 8 AM start), inclusive of decontamination time. Decontamination procedures require approximately 20 minutes for initial rinse, one hour soak with decon solution, and short final rinse, with a minimum of 3 hours allocated for the complete process though actual time may be shorter depending on piping condition. The government will attempt to schedule consecutive shutdown days but timing depends on other projects occurring in affected buildings. Drawing P03 is for reference only to show the leak detection system and temporarily removed piping. The work involves replacing piping in a USDA facility with specific coordination requirements between contractor operations and government oversight.

Questions from Industry 1232SA26Q0470 As of 30 April 2026
1. Will the use of slip fittings be allowed on the new piping? On previous work, the piping was not necessarily square and true, making it difficult to make connections using pre welded flanges.
Govt Response: Yes. This is in the specs.
2. Can the piping be hydro tested at the fab shop? or will it need to be hydrotested on site?
Govt Response: Prefabs can be tested in the shop but we (USDA staff) will hydrotest the system after the piping is installed as well.
3. How long are the individual shut downs?
Govt Response: Each shutdown will be 8 hours and this includes the decontamination time.
4. Are the shut downs during normal working hours?
Govt Response: Yes, probably start at 8AM
5. Do the shut downs include the decontamination time? If so, how long does it take?
Govt Response: Yes. Decons will vary especially with the condition of the piping. 20 minutes rinse of the piping, then we pump in the decon solution, let it sit for 1 hour then pump it out, short rinse, then release the project to the contractor. We allot at least 3 hours for decon time but it may be shorter.
6. Specifications state: “2.6 Testing - All (100%) buttweld joints for "PPW" piping shall be tested per radiography”. Confirm.
Govt Response: Since the prefabs will be utilizing slip flanges, the x ray will not be required for the welds that will occur in the field for these slip flanges. X ray testing should be used for the rest of the welds on the prefabs created in the shop.
7. Drawing P03 is for reference only?
Govt Response: This page is only to show the leak detection system and piping that will need to be removed temporarily until the piping is completed.
8. Will it be one vault at a time?
Govt Response: Yes.
9. Will it be consecutive days or will it be multiple weeks?
Govt Response: We will try to do consecutive days but it will depend on the projects that will be going on in the affected buildings at the time we schedule the shutdowns.
