- ROCK STRIKE QUESTIONS & ANSWERS SET #1 1.There are two batches of laminated glass to be manufactured and tested per this solicitation. The 2nd set are 4 inch x 4 inch samples that the strike face is made from Transparent Ceramic. Since there are 3 major types of Transparent Ceramics on the market I would need the Product Name and Vendor that needs to be used to satisfy this solicitation. All other layers and materials for the samples are explicitly named except for the Transparent Ceramic. Answer: Transparent Ceramic is meant to imply a crystalline or partially crystalline material that is highly transparent in the visible range. We assume that this would be met if the material has 80% transmission at 550 nm and above. Borofloat is not partially crystalline ceramic and not acceptable for this use. The Government will not recommend a specific manufacturer. Note, however, that the transparent ceramic is not described as water white while the remaining parts of the recipe are so designated. 2. The solicitation states the accuracy of the ball shot to 1.18, quoted as within a 1.18 zone centered on the strike face of each coupon. Can you please tell me what the unit of measure is for the 1.18? Answer: The units are inches. 2. 1) It calls out for 6 inch x 6 inch samples and also 4 inch x 4 inch samples...is there any reason they can't all be 6 inch x 6 inch? Answer: The samples can be any dimension larger than 4 inch x 4 inch as long as their strike faces are identified unambiguously. The smaller dimensions reduce the cost of the crystalline ceramic layer. 3. 2) Do we have to currently own all the equipment necessary to complete the work for this solicitation? Answer: No. 4. I am in the process of bidding on this program and wanted to ask a question regarding the Ceramic Balls used for testing: Is it safe to assume a new ball is needed for each impact? I assume this is the case but after reading through the document (attached), I didnt see any reference to needing a new ball for each test. The concern is that the 12mm balls can be fairly expensive and Im finding there is a 4 week lead time on large orders. Timing may not be an issue though but concerned about cost. Answer: Since the internal condition of a used ball cannot be determined, a new ball should be used for each test. The ball could be alumina which should reduce the cost. 5. In section c.4 of the solicitation, one of the layers in the laminate is specified as 0.388 glass ceramic. We request specification of a product name for this layer. If you cannot specify a particular product, please state if borosilicate glass such as Schott Glass Borofloat be acceptable for this layer. Answer: See 1 above and its answer. 6. We would also like to request the thickness tolerance for each layer in the laminate. Answer: Following the recipe of the SOW tables, the vendor may use the nearest commercially available thicknesses. That is, if the adhesive is only available at 0.05 thickness, use 0.05 consistently. Once a recipe thickness has been used, a mixing of thicknesses for any given layer of the recipe is not permitted. Simply put, be consistent in your uses of thicknesses. Mixing a.38 layer with a.50 layer is not consistent. 7. Please clarify if our response to this solicitation needs to provide technical information or just a cost quote referencing the SOW. Answer: A brief description of the materials and their vendor identification as well as enough information to demonstrate the understanding of the problem would be appreciated. 8. Water White Glass is a Trade mark name of AFG Glass Industries. Is this the only approved source or can or equal products apply? Answer: As long as the substituted trade mark or trade name is supplied, any equivalent glass can be substituted. 9. Can we has more specifics on the Glass ceramic requirements, there are several types and manufactures. Answer: See 1 above and its answer. 10. In section C.4 there is a very complete list of materials needed to produce the coupons for the test. The only item on the list that we are not sure about is the first item which is 1 0.388 Class ceramic. Do the technical leads for this project have a more specific type of ceramic glass that can be listed or is the government allowing the contractor to offer up what they feel would be best for this activity? It turns out there are various kinds of ceramic glass and with the same specific guidelines as the other materials we are at a loss on how to respond with cost to you in our proposal. Answer: See 1 above and its answer. 11. Is there any reason the laminations could not be made up in larger sheets and water jetted to the small test sample sizes? Answer: The contractor may make up a large sheet, and cut the coupons from the large sheet.
