- Description
- THIS NOTICE CONSTITUTES AMENDMENT NO. 2 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 submitted by potential offerors. 1) The first sentence of the specification indicates that the building will be used for the long-term temperature controlled storage of batteries. What type of batteries (Lithium, Nicad, Lead Acid, etc.) will be stored inside the building? Please advise. ANSWER) Li-ion and Li-MnO2 will be stored now, but many different chemistries will be used in the future. 2) If lead acid batteries will be stored inside the building, should the interior surfaces be resistant to sulfuric acid? Please advise. ANSWER) No, we will accomplish this with trays and mats. If this can be accomplished for the same price then it will be nice but not necessary. 3) Will battery charging or recovery operations be performed inside the building? Please advise. ANSWER) No charging, the batteries will be pulled out of the freezer and tested. 4) Item 2.g. indicates that the walls, roof, and floor construction should be "...noncombustible...construction with material and design that are to be for maximum...fire resistance...Metal sheets are to be used...." Although metal sheets are noncombustible and have some fire-resistance, they do not provide a fire rating. Is this acceptable or should the walls, etc., incorporate a fire rated design? If so, should they have a fire protection rating of 1 hour, 2 hour, 3 hour, or 4-hour? Please advise. ANSWER) No fire rating is required. 5) Item 2.g. indicates that "... pre-fabricated panels with mechanical fasteners (i.e., cam-lock panels) are acceptable? for wall, roof, and floor construction. If this is the case, it may not be possible to achieve a fire-rated construction. Is fire-rated construction required? Please advise. ANSWER) No fire rating is required. 6) Items 2.g and 2.h indicate that the construction and interior finish is to be vapor tight. Is the intent of this requirement to prevent the escape of vapors from the interior of the building to the outside through the walls, floor, and roof? Or, is the concern to prevent vapors from escaping around the perimeter of each door? In addition, what vapor or vapors will be present inside the building? Please advise. ANSWER) The intent is to keep the moisture out. There is no intent to have any vapors in the building. 7) Item 2.g indicates that metal skins be used in the construction of the storage building. What is the minimum gauge of steel sheet that should be used? Please advise. ANSWER) The worst-case scenario is a 1,000 lb cart with four wheels. 8) Item 2.h states: "Interior Finish: Type 304 stainless steel...." What minimum gauge of 304 stainless steel sheets should be used to line the walls and ceiling? Please advise. ANSWER) There will be no load on the walls. Keep in mind the wind-loading and roof load specifications (See item 2e and 2f). 9) Item 2.h states: "Interior Finish: Type 304 stainless steel...." What gauge of 304 stainless steel sheet should be used to fabricate the floor? (Please note: since this surface will be subject to foot traffic, light gauge material is assumed to be not acceptable). Please advise. ANSWER) The worst-case scenario is a 1,000 lb cart with four wheels. 10) Should the building be equipped with a built-in secondary containment reservoir? Please advise. ANSWER) No 11) Item 4c indicates that the door gaskets be provided with a vapor tight seal. Should these gaskets be magnetic? Please advise. ANSWER) The intent is to keep the moisture out. 12) Regarding item 5.a, please note that explosion-proof heated door seals are not available. Since this will affect pricing for item 27 (Option 3), we recommend that Option 3 be amended to exclude the Class I, Group B, Division 1 requirement for the heated door seals. Please advise. ANSWER) No, this is an optional requirement. If the manufacturer cannot fulfill an individual optional requirement, then please still provide quote for meeting the basic requirements as well as any options that can be supported, clearly noting which options are not included in quote. 13) Regarding item 7.a, can the 6" diameter sampling port be a 6" x 6" square opening instead of a circular one? Please advise. ANSWER) That is acceptable. 14) Regarding item 7.a, does the removable cover need to be lockable? Please advise. ANSWER)No 15) Regarding item 7.a, if fire-rated construction is required (please see question #4), then providing the sampling port through the door will negate the fire protection rating of the door. Is this a concern? Please advise. ANSWER) No fire rating is required. 16) Regarding item 7.b, will the 3/4" metal electrical conduit provided by others be rigid conduit or EMT conduit? Please advise. ANSWER) Rigid conduit. 17) Figure 1 shows the location of the conditioning system on the roof of the building. Instead of the roof location, can it be located through one of the walls? Please advise. ANSWER) Anywhere is feasible as long as the basic inner and outer dimensions are meet. See item 2a. 18) If the conditioning system must be located on the roof as depicted in Figure 1, does a ladder system or service stairway to the roof need to be provided? Please advise. ANSWER) No, a ladder is not necessary and the conditioning system need not be on the roof. See item 2a. 19) Is this a budgetary quote or is this a firm requirement? ANSWER) This is a firm requirement. 20) Can the proposal due date be extended? ANSWER) The proposal due date has been extended until March 8, 2002. The due date for receipt of offers is not extended. Proposals are due March 8, 2002. Companies shall provide the information stated in the synopsis/RFQ posted on the NASA Acquisition Internet Service (NAIS) on 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.
