Posted to FBO 6/26/2018 NLT 1600 MT

Q1. In accordance with FAR 36.204, could you please indicate what the magnitude of construction range is for the Replace Compressors for Constant Temperature Rooms in the NLGRP project?
A1. That information can be found within the provided solicitation, page #40.


Q2. If this requirement is a services or supply contract (not construction), please indicate so and disregard this request for magnitude.
A2. N/A, this is a construction project.


Q3. I was hoping you could tell me who the original installer/manufacturer of these rooms was; presumably their signage/logos are on the rooms and/or control panels.
A3. The boxes were manufactured by Bally Refrigerated Boxes.
- The subcontractor that provided them was Steve Stock and Associates.
- The General contractor was M A Mortenson.


Q4. GENERAL: There are several temperature controlled rooms observed in the walk through that have larger evaporators than what the air heat load and product holding loads alone would account for. In addition to the technical specifications listed on Temperature_Control_Rooms_20180419v2, to size systems accurately we request (the following 4 questions to be answered)
When originally built in 1991, certain environmental rooms were designed for a much wider range of temperatures with supplemental electric heating coils attached. These supplemental devices were found to be unnecessary and were removed but the evaporators were not resized.
Q4. Existing evaporator make and model numbers for all systems in this proposal?
A4. See photos in Attachments "South Rack Photos" and "West Rack Photos"



Q5. Existing compressor make and model numbers for all systems in this proposal?
A5. See photos in Attachments "South Rack Photos" and "West Rack Photos"


Q6. temperatures, weights, and frequency of product being loaded into each temperature controlled room?
A6. Material loading into the room is estimated at 100 lbs maximum at room temperature per day, with it likely being much less. Frequency is a maximum of 30 door openings per day for approximately 15 seconds each.


Q7. any additional heat sources in each room (i.e. unusual lighting, room occupied for lengthy periods, etc...).
A7. Rooms 206, 223, 224, 225 are equipped with dehumidifiers to maintain set humidity levels, but the dehumidifiers are in the interstitial space above the rooms, so the heating elements are not in the rooms, only the dehumidified air is returned to the room.


Q8. In the SOW document: "FCco_NLGRP_Replace_Compressors_for_CT_Rooms_SOW_-__20180420v5.pdf" section C, subsection 1 states "Rooms are monitored and controlled by existing Johnson Controls MetasysTM Building Automation System." (3 associated questions follow)
Please provide information on how the Metasys system is controlling the temperature.
Will this system need to be reprogrammed for any of the TC rooms in this proposal and will Metasys programming be the contractor's responsibility?
A8. T"FCco_NLGRP_Replace_Compressors_for_CT_Rooms_SOW_-__20180420v5.pdf" section C, subsection 1 is modified to state, "Rooms are monitored and controlled by existing Johnson Controls MetasysTM Building Automation System." All control functions for compressors and evaporators to maintain room temperature will be controlled by KE2 controllers.
The evaporator fans are to run continuously except when a defrost cycle is in progress. The Johnson Controls MetasysTM BAS will only monitor the rooms for temperature. Humidity control will still be controlled by the BAS.


Q9. In the same document, section G describes a KE2 LDA interface to be furnished by the contractor. What is the expectation for communications between this device and the Metasys system?
A9. There is no expectation for communication between the LDA interface and the BAS. All KE2 controllers will be connected to LDA interfaces.


Q10. Will this be the contractor's responsibility?
A10. The contractor shall be responsible for connecting All KE2 controllers to LDA interfaces.


Q11. In the SOW document "FCco_NLGRP_Replace_Compressors_for_CT_Rooms_SOW_-__20180420v5.pdf" section H describes an infrared leak detection system in the TC rooms and compressor racks that "...shall report to a central monitoring station to alert staff of leaks." Please detail the type of staff alert required (i.e. audible alarm, visual alarm, text message, outgoing signal to other system, etc...).
In the case of audible and visual alarms, please detail locations of each.
A11. The contractor shall provide dry contact point (s) on the sensor for Maintenance that we would then tie into Building Automation System.


Q12. In the SOW document "FCco_NLGRP_Replace_Compressors_for_CT_Rooms_SOW_-__20180420v5.pdf" section F designates R-507a to be used in all systems. When converting from R-22 to R-507a system gasketing and seals will shrink due to the change of content of chlorine in the refrigerants. These gaskets and seals will leak when they eventually shrink. Is the contractor responsible for refrigerant leaks in existing equipment and existing piping in this SOW?
A12. Yes, Gaskets and seals not replaced while upgrading condenser and evaporator components shall be replaced to maintain long term integrity of the system.


Q13. If so, what duration after completion is the contractor responsible for refrigerant leaks?
A13. The contractor is responsible for materials and labor to repair refrigerant leaks for one (1) year after completion of the project.


Q14. Will the mechanical contractor be responsible for installing new KE2 LDA central interface?
A14. Yes


Q15. If so, where is the desired location of interface?
A15. In reviewing the KE2 LDA documentation, a single LDA can only monitor 10 controllers. The two controllers are therefore necessary. The LDAs should be centrally located on the first and second floor in the facility and should be easily accessible for visual monitoring and servicing. A suggested location for the first floor would be in Elevator control room as it is central to all the rooms and can easily be connected to a patch panel for intra/ internet access. The second floor LDA could be located outside of room 225 and then connected via a contractor installed LAN wire to the nearest patch panel for allowing intra/ internet access.


Q16. Will the mechanical contractor be responsible for installing new central refrigerant monitoring station?
A16. Yes


Q17. If so, where is the desired location?
A17. The refrigerant monitoring station should be centrally located in the facility and should be easily accessible for visual monitoring and servicing.


Q18. Can the USDA provide design cooling load capacities of each cooler?
A18. No, but room dimensions, insulation information, temperature range, material loads, and frequency of door openings have now been provided for experienced refrigeration technicians should be able to calculate the cooling load requirements.


Q19. If none are provided, load calculations will be made using assumptions as necessary.
A19. Yes.


Q20. The current refrigerant line-set size has been deemed unsuitable for re-use with 507. Can other refrigerants be provided to avoid the need to run new piping? Please advise.
A20. In their current condition, yes, but the Contractor is required to clean the existing refrigerant lines, vacuum test them, and prepare them for 507 refrigerant, which we consider to be reasonable. If a Contractor disagrees, please provide the specific reasons the refrigerant line-sets would not re-useable.

Q21. There are a handful of evap coils that do not appear compatible with the new temperature requirements. In addition, retrofitting the existing coils to match unknown original performance data poses challenges. It is recommended the SOW include new evaporator coils for each cooler to ensure a successful retrofit. Please advise.
A21. Not all evaporator coils are anticipated to be sized incorrectly, if the proposals show the coils to be substantially oversized, then we will consider that in our evaluations.


Q22. A proper retrofit is expected to well exceed the current high limit of $250k. It is recommended the limit is increased to $500k to allow adequate funds for fair/competitive bidding. Please advise.
A22. Proper is a vague term, and the Government has limited funds for this project.


Questions heard verbally during the site survey, that were not ever officially received in writing (as instructed by the CO), but the unit would like to clarify any items to receive better proposals.

Q23. Is the unit going to hold contractors to the 200 micron for 24 hours standard? Someone stated that the industry standard was 400 micron.
A23. 300 microns initially with rise over 24 hours provided that referenced GreenChill guidelines are followed regarding testing the system. See attachment "Excerpt from GreenChill". The full document can be found here. https://www.epa.gov/sites/production/files/documents/leakguidelines.pdf


Q24. Is any other refrigerant than R-507 okay?
A24. No


Q25 If during leak testing the contractor finds an issue with a line set that they were reusing, is its repair covered under this contract.
A25. We anticipate that the lines are intact and if it is found that an existing line(s) were compromised this would be change in site conditions and required repair would therefore be a modification to the contract.
