The purpose of this amendment is to provide answers to all of the questions that have been received: 1. Question: "On the frames, the proposal states 3 x 8.25 x 3 ‘C formed channel'. Is this a stock structural channel size, or is it a fabricated structure with three individual pieces, continuous welded. I have found a structural channel MC9 x 23.9 that is similar, but not exact dimensions." Each frame will be made from a ‘C' formed channel of 3/8" thick hot rolled mild steel (ASTM A-36) in the following dimensions: 3" side by 8.25" base by 3" opposite side. Answer: Yes - MC9 x 23.9 is acceptable. The stated dimensions are approximate in relation to standard CMU concrete blocks. The inside dimensions of the ‘C' must be larger than standard CMU blocks. 2. Question: "On the Cart, similar question: Are the ¼" formed channels standard structural channels? I am looking at a C9 x 13.4 for the 8 ft runners and a C10 x 15.3 for the 30 inch tall vertical supports. Is this acceptable, or does the "C channel" require three pieces continuously welded the entire length?" CLIN 0008: Firm Fixed Price (FFP). Frame Storage Rack capable of holding 7 filled frames, approximately 8 feet in length. Qty: 16, Unit of Issue: Each. Answer: From the conceptual drawings provided at the pre-bid meeting (February 25, 2009), the vendor can interpret and submit a design that meets CLIN 0008 requirements. The government can work with winning vendor to optimize the design. Bearing in mind that these racks will be used to store and transport up to seven frames filled with CMU, the design and materials must be very robust. 3. Question: "On the ½ inch mount plates CLIN 0007, do I read this correctly, that on-site welding will be required to fit the 4 corners into the existing structure to match each frame?" CLIN 0007: Firm Fixed Price (FFP). The contractor shall provide and install ½" mount plates for the reusable metal frame. All welds shall be coated with zinc rich paint. Qty: 168, Unit of Issue Each; Answer: There will be four plates welded into 42 opening; two on top and two on bottom. This is a clarification from the pre-bid. 4. Question: "Delivery in 60 days ARO, is this for the entire shipment, including potential on-site mounting of the ½" mount plates (CLIN 0007)?" Delivery: Delivery is required not later than 60 days after contract award, accelerated delivery is requested. Answer: All frames must be delivered and all mounts must be welded within 60 days of contract ward. NLT day 61, acceptance testing (fitting frames into opens and attaching to mounts) will begin. 5. Question: "I attended the Pre-bid yesterday and asked the tall gentleman about the channel that is used for the breach walls. He stated that we could simply use MC channel. The drawings call for a formed channel 8 3/4" to the outside, 3/8" wall whereas a WC-8 channel would only allow approximately 7 1/4" inside. Does the channel need to have 8" flat surface at the bottom on the inside or can it have break radiuses in the bottom and be 8" the rest of the way up the 3" wall?" Answer: See Question #1 6. Question: "I was going to go ahead and plan on hot dip galvanize the frames and storage rack. This should be better than zinc rich paint, but we can do it just about as cheap. An then cold galvanize the welds where we field weld the ½'' thick mount plates in the field. Would this be acceptable?" From CLIN 0007 (referencing that mounting plates): All welds shall be coated with zinc rich paint. From Section C: All frames and hardware will be treated with a rust preventive black or gray paint. Answer: Yes to all. Hot dip galvanize is a highly desirable rust treatment and would be an acceptable substitute for black or gray rust preventive paint. 7. Delivery/Installation will be made to Fort Story, VA 23459 not to NSWDG, 1636 Regulus Avenue, Virginia Beach, Virginia 23461-2299. A specific delivery address will be provided upon receipt of award.
