- Description
- The synopsis is being posted to both the Federal Business Opportunities (FBO) page located at http://www.fbo.gov and the Navy Electronic Commerce on Line (NECO) site located at http://www.neco.navy.mil. While it is understood that FBO is a single point of entry for posting of synopsis and solicitations to the internet, NECO is the alternative in case FBO is unavailable. Please feel free to use either site to access the information posted by the Navy Sea Systems Command. The Naval Surface Warfare Center, Dahlgren Division, intends to procure on a competitive basis, one, NEW modified (customized/altered) freight (cargo) container in accordance with specifications attached hereto. Container is constructed of corrugated steel sides and roof, with locking steel double end swing doors (14 gauge minimum). Floors shall be minimum 1-1/8 thick marine wood, forklift tested to 16,000 lbs per 44 square inches. Each wall tie down steel lashing ring shall have a minimum 6,000 lbs capacity. There shall be front corner post tie downs. Door corner post tie down (restraint) shoring slot shall support minimum 2 x 6 lumber. Minimum outside dimensions of container shall be 40 ft 0 in x 9 ft 6 in x 8 ft 0 in, with door opening 8 ft 5 in x 7 ft 8 1/16 in. Minimum inside dimensions of container shall be 39 ft 5 in x 8 ft 10 in x 7 ft 8 in (before insulation is installed). Approximate gross weight of container (before modifications) estimated at 67,200 lbs, with capacity of 2,690 cubic feet. Container shall not be required to have CSC certifications. Modifications shall include an additional 36 steel door on road side of container near rear of container, electrical wiring (includes UL approved waterproof junction boxes) exterior and interior lighting, an air-line filter/regulator, a compressor, an HVAC unit, workbenches, shelves and circulation fans, partitions, insulation, ventilation (turbine & louver vents). The following deviations/changes/alterations have been submitted by potential bidders, reviewed and approved by the technical representative: Q: 1. Does the electrical conduit called out need to be installed behind the wall or mounted outside on the wall structures as this changes the wall structure fabrication wise quite a bit. A: 1. The conduit and electrical boxes do not need to be behind the surface of the wall, they can be mounted to the wall surface. As long as they are securely mounted in such a manner that repeated use does not pull them off the wall in the future. Q: 2a. The SOW states for insulation 1 foam with 3/8 thick plywood and a.030 thick high density polyethylene white pebble face, looking for a minimum of R-12 factor for insulation. In speaking with the vendor to reach that requirement you would need 2-3 inches of insulation to get the R-12 factor. We would like to know which of the two has precedence the R factor or the thickness. A: 2a. My preference is that we use 1 foil backer foam board with 3/8 min plywood over that, and a top layer of.030 white pebble HDPE, for the finish face. This will give us the insulation we need and durability for keeping the walls clean. Q: 2b. In many ISO containers we provide conversion on we use a spray on Insulation from Mascoat which then provides us the wall room to add in additional insulation panels to achieve the R factor. www.mascoat.com A: 2b. I want to stick with what is specified in the 3.4.1 under insulation and ventilation 3.4 of the SOW - (foil backer 1.5 foam board, 3/8 plywood,.030 white pebble HDPE face) thicker plywood can be substituted if 3/8 in not available. Q: 3. Electrical Requirements: Are the electrical panels and outlets to be wall flush or surface mounted? A: 3. With the exception to the main breaker panel item #5, they can be flush mounted as long as they are securely mounted in such a manner that repeated use does not pull them off the wall in the future. The breaker panel can be flush mounted if; some type of support structure is fabricated such that anchors the breaker panel securely to the cargo container structure. Q: 4. For the Compressor Room we would like to recommend adding a 2 pole switch to control the compressor. A: 4. Yes this is a good idea and if there is a commercial code that might require a 2 pole switch at the compressor I am ok with that, but I do not want to relocate the compressors breaker. Q: 5.Can we use a flex conduit for installation and if not what type of connectors would be desired for the rigid conduit, screw or compression? A: 5. I do not want flex conduit used, and the connector(s) are contractors choice, screw or compression will be fine as long as ridged conduit is used. Q: 6. Note: The NEMA 3R enclosure for the pig tail the backside of the power cable must be rated 100 amps, Concur? A: 6. The answer is yes. Q: 7. Is 3/8" FRP faced plywood an acceptable alternative to a white pebble HDPE faced plywood? A: 7. I want to stick with what is specified in the 3.4.1 under insulation and ventilation 3.4 of the SOW - (foil backer 1.5 foam board, 3/8 plywood,.030 white pebble HDPE face) thicker plywood can be substituted if 3/8 in not available. Q: 8. Is fiberglass insulation with an R value of 12 or higher an acceptable alternative to 2" foam/board? A: 8. Same as question 7, I want to stick with what is specified in the 3.4.1 under insulation and ventilation 3.4 of the SOW - (foil backer 1.5 foam board, 3/8 plywood,.030 white pebble HDPE face) thicker plywood can be substituted if 3/8 in not available. Q: 9. Is it possible to simply mount the external lights on the exterior rather than build (2) 20"x20" boxes and weld them in place? A: 9. Under 3.5 bullet 3 defines the fabrication of two (2) housings for light fixtures approximately 20 x 20 , and welded in place on the cargo container creating two cavities to control water intrusion. A suitable alterative to bullet 3 under 3.5 would be to manufacture two (2) little awnings or water deflector and welded to the cargo container. This would be acceptable if they are angled away from the cargo container like awnings, and if the pass-through hole for the wiring and the body of the light fixtures are covered by this alterative process. Simplified Acquisition Procedures (SAP) will be utilized for award in accordance with FAR Part 12. The order shall be firm fixed price.
