About this file
This document provides details for solicitation number 12505B22R0005 to install a multiplex water softener system at a USDA facility in Ames, Iowa. The solicitation is a request for proposals for a firm-fixed price construction contract valued between $250,000 and $500,000. The small business set-aside requires the prime contractor and first-tier subs to have average annual receipts less than $16.5 million. Interested vendors must register in SAM.gov and monitor the site for amendments by June 17th when questions are due. A pre-registered site visit will be held on June 8th or 9th. The one-year period of performance begins after notice to proceed. The document includes questions and answers specifying no substitutes for materials like copper, brass, or control types. Dimensions cannot exceed 12'10"x4'2" and flow rates cannot be reduced.

2022.pdf, page #2, red outlined softener skid area: Can the softener skid footprint exceed the dimensions shown in Red?
No
2 2. SOW pdf, page #2, item p.: Can Schedule 80 PVC, CPVC, stainless steel or galvanized face piping be substituted for copper piping?
No
3 2. SOW pdf, page #2, item t: (A) Can control valves be made of other materials? (B) Can control valves be air or water controlled rather than electronically controlled? (C) Can butterfly valves be substituted for ball valves?
(A) No
(B) No
(C) No
4 2. SOW pdf, page #2, item t: Will USDA consider accepting valve assemblies or manifolds as an option?
No
5 2. SOW pdf, page #3, 2. Items to be viewed on BAS and locally at HMI, items c/d/e/f: (A) How many individual hardness and individual conductivity monitors are requested on the skid?
(B) How frequently are hardness tests required to be sampled?
(A) 5 harness meters and 5 conductivity meters, this includes all 3 resine tanks and the skid. (Each softener/resin tank shall display outlet hardness and conductivity and have an adjustable programmable alarm. The combined softener unit shall display inlet hardness and conductivity and have an adjustable programmable alarm. The combined softener unit shall display outlet hardness and conductivity and have an adjustable programmable alarm.)

8 There is a conflict with specified flow rates and footprint required for the equipment. Resign hydraulic calculations show 5’ diameter tanks are required and will not fit it the space. (A) Can the space be expanded or (B) system broken into two skids with the single tank skid facing the double tank skid? Hopefully this would allow enough space for the future boiler-or (C) alternatively can the flow rate be reduced to accommodate tank dimensions that will fit the footprint?
(A) No
(B) No
(C) No
9 Can the 304SS ball valves be used in lieu of brass? No
10 The drawing in solicitation # 12505B22R0005 calls for the softener skid to fit in an area 12’-10” x 4’-2”. We can’t meet this space requirement and your flow specifications. We’d need a footprint at least 12’-10” x 4’-10” for a skid package. Please advise.
No
11 We’re also having an issue with getting the specified flanged brass ball valves. Could we use stainless steel or cast iron for these?
No
