Industrial Water Treatment PILOT Solicitation Questions and Answers.docx

Industrial Water Treatment PILOT Solicitation Request for Information Questions

1. How much water is being treated (how much makeup water is used per year)

· NIH does not have this data. The systems are relatively new. NIH does not anticipate leaks in the system.

2. What kind of equipment is required?

· Vendor to specify appropriate system to perform SOW

3. What type of metals are in the system?

· NIH assumes Black iron and Copper. Per the SOW, the vendor will perform a metallurgy survey of the systems to verify.

4. Would you please provide the current pictures of the water treatment systems?

· Vendor can schedule a site visit to obtain pictures (unfortunately the timeframe for the site visits has already past)

5. Can NIH provide water make-up pipe diameters for all 8 closed loops?

· Vary. Most are at least 20 mm per drawings

6. Can NIH advise if all 8 closed loops have existing, functional water meters?

· Not all systems have functional water meters

7. Section B.4.1. Options – The contractor shall provide an estimate to execute the SOW. The bidding water treatment vendor(s) do not know the existing treatment levels or if the current glycol percentage is 40%. It would be helpful if we were allowed to gather samples and test the current conditions so it will enable us to provide a proper estimate to know the current system levels. Will NIH allow our company to re-visit the site early next week (Monday or Tuesday) and gather water and glycol samples and submit them to our lab?

· Please assume that glycol level treatment is 40%.

8. If question 3 response is yes, can NIH extend bid due date another week to allow for lab lead time testing?

· No

9. All 8 closed loops appeared to have filtration systems, due to the filer housing having insulation on them it we were unable to see during our walk-thru the model or serial number on each housing, will NIH provide the filter housing model and serial number so we can establish the correct pricing for the filters required?

· Please provide the typical filter housing pricing for this application in your estimate

10. Section B.10. – The SOW calls for a tie in of the existing NIH Siemens BAS system, can NIH confirm this is for an open loop (cooling tower system) and is not required for closed loop systems?

· Required for all loops identified in the SOW

11. Section B.11. the preheat glycol systems have what appeared an automatic glycol system. Can NIH confirm if the units are working?

· The glycol injection units are operational

12. NIH is requesting coupon racks at all closed loops; will NIH be installing these racks for all 8 closed loops?

· Corrosion racks should be installed where necessary based on Vendor technical expertise.

· Please note section B.12.5. Water Corrosion Rate Meters: Provide options for Corrosion rate meters that can provide instantaneous measurements of corrosion rates at any given point in time

13. Section B.13.1. Clean and Passivate Hydronic Systems. Currently, the bidding water treatment vendor(s) do not know the current state of treatment or glycol percentages of each closed loop. We as a will we be able to provide solutions and proper pricing for this work?

· Yes. In line with SOW

14. If awarded the contract, will NIH provide separate funding to properly treat, clean and add the correct percentages of glycol for any loop needing to meet the SOW?

· Please consider in your estimate all contingency to perform work specified in the SOW.

15. Section B.13.7. – will NIH accept MONTHLY testing as these systems are closed loops?

· No. Vendor will comply with specification in SOW. NIH may reconsider at a later date

16. Section B.15.5. – secondary containment, we did not see any containment during our walk-thru. Based on the spec that is written, will the water treatment vendor be required to provide second containment? If so, will NIH allow containment pallets that meet the SOW?

· Yes

17. Will NIH allow vendor to order chemical & glycol inventory and store products at specified location in Building 10?

· Yes

18. Will NIH allow for non-glycol closed loops systems chemical to be sodium nitrate with azole (copper corrosion inhibitors)? The SOW says Nitrite, the “Evaluation Criteria for E & F Wing” #4, says no Nitrite, please advise what closed loop inhibitor is to be used.

· Typo. The Evaluation criteria should state “NITRATE”. Nitrite base Azole treatments are acceptable per the SOW

19. Can NIH provide the last 3-month current service reports from existing vendors that show all 8 loops that is on this SOW?

· There is no current treatment. Assume glycol is for freezing protection only.

20. Will glycol be purchased separately from the contract?

· No. Please consider all contingency in pricing in responses to perform SOW.

21. Is the vendor responsible for glycol fill tank repairs?

· Yes, when required by the NIH.

22. Is the vendor responsible for replacement filters and operation?

· Yes

23. What is the current contract value?

· NIH per FAC cannot provide Independent Government Estimates to Bidders on a contract due to conflict of interest concerns.

24. Who does the current equipment belong to?

· NIH Division of Facilities Operations and Maintenance (DFOM)

25. If the equipment needs to be replaced, will the customer purchase from the vendor?

· If in the interest of the Government.

26. I have a question pertaining to the Statement of work section B.5 to B.12. Can you clarify if we need to price Section B.5 to B.12? If so, we will not be able to provide an accurate price without Measurements and drawing of the system.

· Vendor should provide pricing according to the SOW. NIH assumes all vendors bidding to execute are experienced with performing the SOW and can provide reasonable pricing.
