- THIS NOTICE CONSTITUTES AMENDMENT NO. 5 TO THE COMBINED SYNOPSIS/RFQ FOR 1 HAZARDOUS MATERIALS WALK-IN FREEZER DESIGNED WITH A BASE THAT IS AN INDEPENDENT LOAD SUPPORTING SYSTEM. MUST BE RATED FOR OUTDOOR ENVIRONMENT IN HOUSTON, TX. Companies shall acknowledge all amendment(s) in their quote. This notice serves as the official amendment to subject synopsis/RFQ and a written amendment will not be issued. The purpose of this amendment is to respond to questions no. 24-36 submitted by potential offerors. Questions and answers 1-23 have been posted under previous amendments. Question 24. Regarding the request for bid, I cannot find the size of the walk-in required. Could you please let me know? Answer 24. See item 2a, 2b, and 2c. A brief summary is as follows: ? External dimensions: 20?length (L) maximum, 10?width (W) maximum, and 9?height (H) maximum. ? Internal dimensions: 17?L minimum X 8?W minimum X 7?H minimum. ? Interior storage capacity: Unobstructed space of 952 cubic feet, minimum Question 25. We can furnish the box and the refrigeration complete with delivery and installation. If this is possible, how do I get a complete copy of the specifications and modifications? Answer 25. Yes. The specifications are located at: LINK: http://procurement.nasa.gov/cgi-bin/EPS/bizops.cgi?gr=C&pin= Solicitation BH13-78-02-47P Response Due: March 22, 2002 Title HAZARDOUS MATERIALS WALK-IN FREEZER DESIGNED WITH A BASE THAT IS AN INDEPENDENT LOAD SUPPORTING SYSTEM. MUST BE RATED FOR OUTDOOR ENVIRONMENT IN HOUSTON, TX. Question 26. We are attempting to bid your Houston project but have not been able to locate the 'drawings' referred to in the Specification. Could you please assist us so that we might have the opportunity to present a bid? Answer Yes. The specification posted on March 7, 2002, has been updated to include the referenced drawing. The specifications are located at: LINK: http://procurement.nasa.gov/cgi-bin/EPS/bizops.cgi?gr=C&pin Question 27. We have looked all over the referenced Specifications and in each of the attached files, but cannot find any drawings as referred to in the Specifications (i.e - figure 1, figure 2, etc...) Can you advise? Answer 27. Figure 1 & Figure 2 are referring to the same figure. Somehow these diagrams were lost during the posting process. The specification posted on March 7, 2002, has been updated to include the referenced specification. Question 28. The factory ran a heat load test for this freezer and calculated a 15 HP compressor is required for this application. To ship a pre-assembled package, the condensing cannot be roof mounted. They propose to position it along 1 nominal 10' wall this would require locating 1 door on the nom 20' wall. Will this be acceptable to you? Answer 28. The door may be located on the length side (see Figure), however it is preferred to be located on the opposite width-end of freezer. See item 4a. If an additional ?footprint? is needed, then the manufacturer may separate conditioning system, temperature recorders, etc? into different units from the basic structure that is limited to fitting within these external dimensions. See item 2a. Question 29. The factory suggests that NASA should have specked 2 refrigeration systems to provide redundancy and back up. Should this be quoted as an alternate? Answer 29. Yes. Items 1 to 24 in the specifications sheet are the basic requirements that must be fulfilled. Please itemize the quote to illustrate the price of meeting the basic requirements and a separate list of the cost of each optional item. Question 30. The 15 HP condensing unit requires 100 amps @ 230/3 phase. The power to be provided is 30 amps. Can this be increased? Answer 30. No these four circuits are the only circuit available in the designated location. See item 23.a. Question 31. If the factory provides one-point power connections, do they need to have an electrician on site? Will Grounding connection be provided? Answer 31. No, NASA will make site utility connection, including connecting up the specified grounding lug. Keep in mind the bid submittal requirements (items 24.a, 24.b., 24.c., and 24.d.). These will assist our technicians in setting up the freezer. Question 32. Is there a prevailing wage scale available and do workers need to be union? What type of safety courses do they need to attend? Answer 32. We will set the freezer up. Question 33. (Item 13) Spec is asking for "explosion proof", yet calling out electric defrost. Is this correct? I suppose this could be accomplished (at great cost) but what is wrong with hot gas defrost which does not involve any electrical connections? Answer 33. Explosion proof is an option. See item 27. Keep in mind to itemize the quote to illustrate the price of meeting the basic requirements and a separate list of the cost of each optional item (including changes in the basic requirements, See item 24.d.) Question 34. (Item 12) Spec is calling out a "product" load of 5,000 #/day with a specific heat of 1. If, in fact this is actually a liquid and it needs to be frozen (to -20?C), the refrigeration required would be about 20 tons (rather than the spec estimate of 5 tons), If the "product" is something else (and does not "freeze" then the 5 tons is close. Anyway, it would be nice to know what the product is. Answer 34. Large batteries. Lithium Ion and Lithium Manganese Dioxide. In the future, different battery chemistries will be stored. Question 35. Item 17 - Please clarify the specific requirements to be submitted. (ex: max ref. pressure, max cooling water pressure, etc.) Answer 35. Maximum design pressure and maximum/minimum design temperature for each fluid leg of each pressure system. The intent of this is to provide information so that the NASA Pressure Systems Engineer can determine if the system meets NASA JSC Pressure Systems requirements. See related item 24.c. Question 36. Item 26 (Option 2) is not clear. If only 1 pound of CO2 is vented (in 6 seconds) this results in about a 250? scfm "surge". Is this requirement simply an increase flow rate for the dry air purge of Option 1? Answer 36. This is in addition to the normal pressure equalization capacity. Keep in mind to itemize the quote to illustrate the price of meeting the basic requirements and a separate list of the cost of each optional item (See item 24.d.) The due date for receipt of offers is not extended. Companies shall provide the information stated in the synopsis/RFQ posted on the NASA Acquisition Internet Service (NAIS) on February 27, 2002. Documents related to this procurement are available over the Internet and are in Microsoft Office 97 format and reside on the World Wide Web (WWW) server which may be accessed using a WWW browser application.
