Description

This modification to N68936-01-R-0071 is to include the extension of the response date and a series of technical questions and answers. The response date is now extended and all required information must be received on or before 12:00 PM Pacific Daylight Time 09 May 2001. The technical questions and answers are as follows: I) Synopsis/Solicitation: Does (CLIN 0002 -- Trailer) represent a fully integrated trailer system or base trailer? Not completely sure of your terminology. The trailer will be used to supply power (generator) and store equipment. The Van/Trailer will be driven to a test site then power connections made if necessary. The equipment in the van is not intended to be operational while the vehicle is being driven. What is a Contractor Established Code? Duns and Bradstreet number. 2.1) General Requirements: Does drive on mean drive forward on/back off or back on/drive forward off? Either way is fine as long as no disassembly is required. Preferably trailer will be attached to the van during loading and unloading, but not a hard requirement. Will other military or commercial aircraft be used to transport the system? Each aircraft has a unique angle of incline affecting ground clearance. Thought C-130 was the tightest requirement, but C-17, C-141, C-5 and C-130 might all be used at one time or another. We do not anticipate shipping van via commercial airfreight. All other requirements for military airfreight shall be met. (Provisions for draining fuel, tie down points, center of gravity, etc.) 3.1) Chassis Clarification: Ford E-350 is not a requirement, but merely an example of the approximate size. Any vehicle meeting all required performance specs will be considered. A number of drive train/suspension modifications will be required. In many cases vehicle manufacturers do not offer the modifications. Ford E-350 not a requirement, but merely an example of the approximate size. Any vehicle meeting all required performance specs will be considered. Vehicle should adhere to industry safety standards. Manufacturer/Contractor should warranty vehicle in delivered configuration. Does the factory warranty have to be maintained? No. Does the company performing the modifications require factory endorsement? No. Air ride rear suspension or similar shock absorption system is specified. Is this for operational stability or height adjustment? This is to protect delicate and expensive test instruments during transit. Stabilizing Jacks will be used for operational stability on location. These jacks are not required to lift vehicle off the ground, but to do limited leveling and ensure vehicle and mast are stable during operation on location. A 4,000 lb. top of vehicle (cargo weight) is estimated/specified as a minimum. The Ford E350 has a 9,400 lb. GVWR. After the accomplishment of the 4x4 and dual rear wheel modifications the vehicle curb weight will be 6,600 lbs. The remaining cargo weight will be 2,800 lbs. Ford will not increase the allowable GVWR on this vehicle. We need clarification on this issue. Is the customer just looking to fit the specified equipment into the vehicle? Did they specify 4,000 lbs. minimum to give themselves adequate allowance for additional pack out? The 4000 lb. figure is a round estimate with padding for margin. Our vans in the past have always ended up being at or over max weight once they are fully equipped. This has made our existing vans (which are much larger -- trucks actually) sluggish and challenging to drive to some of the remote test locations. If the requirements cannot be met with the Ford platform, please propose another. Our goal is a vehicle that is as small and portable as possible while being able to meet all of the operational requirements. A 4,000 lb. minimum towing capacity is specified. However, no specific trailer weight or payload is specified. Is there a desired payload for the trailer? Are we designing just to carry the specified equipment? The trailer should be designed to carry the specified equipment (Generator +40 gal fuel tank, additional fuel cans, spare tire, spare test equipment and tools). The spare test equipment could total up to 400 lbs. and tools are generally heavy as well. Design accordingly. 3.2) Cab: Can you provide more information on the (Remote alarm with impact, door (all doors), and motion sensors)? The vehicle will have to be parked overnight from time to time during long transits. The alarm requirement is to provide security during such times. Standard high-end automotive alarm system should be sufficient. "Motion sensors" refers to vehicle motion, not intruder. How many 12Vdc outlets are required? Four 3.3) Van Enclosure: What is your specific operational ambient temperature range? +10 to +110 degrees F. What is your operational humidity requirement? Less than 90% non-condensing. What temperature range (delta T) must the Environmental Control Unit (ECU) or air conditioner/heater maintain in the interior of the enclosure? Delta T 36 degrees F. Up to 35 degrees F cooler than outside temp/65 degrees warmer then outside temp. Do you have any specific shock and vibration requirements for the EMCOR racks? Specified Barry cable mounts rated for weight of rack and equipment will be sufficient. How much will the integrated equipment weigh in each rack (maximum)? 300 pounds. Do the 6" x 6" bulkhead feed through panels require hinged panels or steps for multiple connector rows? Panels to provide 4 type N and 4 SMA feed through connectors. Doors over panels to protect connectors in transit. Feed throughs should be mounted in a removable 6X6 plate for easy modification as required. (Plate could be replaced to provide a different feed though configuration). Is the Quick disconnect Hubble connector the same connector discussed under section 3.4 (Connector for receiving and/or supplying AC power)? Yes. How many floor tie downs are required? 4 points minimum or two 48" sections of unistrut to secure UEU in rear of van. How many ceiling tie downs are required? 2 or more, or rail system for securing additional equipment during transit. What are the vent fans used for? Distributing the conditioned air from the ECU? Yes, to circulate air to the electronics. What is the dimensions and weight of the UEU? Weight 250Lbs size L48" x W 25 x H 25". Will the test equipment be operated while the system is being driven? No. Are there any minimum interior headroom requirements? 6'4" person should be able to sit upright in chair in the work area. More headroom is better as long as overall height limit is not exceeded. Do you want a grounding stud on the van enclosure? Yes. EMCOR racks -- Do you want the rack depth to be 31.5" (cargo van enclosure diagram) or 31" (SOW)? Is this an interior or exterior dimension? The EMCOR website shows specified standard depth of 30.75 inches, which I believe is interior dimension for equipment being installed. The outside depth dimension is closer to 31.5" Use of standard stock size is best. Section 3.3 Emcor Cabinets: The 48" H dimension. Does this 48" H include the Barry Mount? No. What is the P/N of the Barry Mount? CMO-2508-3B. What is the max load for each cabinet? Need this for the correct load factor for the Barry Mount. 300 lbs. Exclusive of rack. Where is the center of gravity for the cabinets? 12" from the front (i.e. front heavy) and about 25" from the floor. The Detachable/Sliding Desktop. One piece or 2? The Detachable/Sliding Desktop can be one or two pieces as long as they are reasonably smooth and stable. Whatever way is more convenient and depending on the type of desktop considered. Contractor to bid best working solution. 3.4) Electrical System: How many 120 Vac, 60Hz, 30A and 208 Vac, 400Hz, 3-phase, 20A outlets are required at each rack? 12 x 120 Vac at each rack the 208 Vac requires 2 outlets at the converter. Will the Van enclosure require power from the generator while the system is being driven? No. 3.5) Trailer: Are there specific storage volume requirements for the tool chest area? Approx. 2' wide X 4' high X 20" deep with installed tool chest drawers. Four shallow hand tool drawers and other drawers for larger tools/parts. Does the length of the trailer include the tongue? No. 3.6) Ancillary Equipment: A WILL-BURT model 6-25 or equivalent mast is specified. However, the model 6-25 mast does not meet the specified requirements (Motor-rotatable is specified). The model 6-25 mast does not have an integral rotator. The addition of an external rotator may have height implications for a vehicle such as the Ford E-350 van. Is an external rotator modification required? The antenna must rotate. Locking mast is specified. The 6-25 mast specified does not have a locking collar. The model 6-25 requires a constant supply of air to remain extended. The WILL-BURT model TMD 7-30-4xx is equipped with a locking collar. However, this mast is a foot longer in the stowed position and may create height implications for a vehicle such as the Ford E-350 van. Is a locking collar modification required? A 25' minimum pneumatic mast with locking collars for each section is required. The mast needs to support up to a 150-lbs. load at the masthead. Entire mast will be motor-rotatable, probably via an external rotator. Contractor will mount required equipment to meet all other physical specs. What are the sound dampening requirements for the blower and inverter enclosures Best possible. Provision for drawing/venting cooling air from/two outside should be provided. (1-1/2 inch ABS pipe, weather/rodent proof) Sound shall be attenuated a minimum of 12db at 400 Hz. Do you also require a sound dampening enclosure for the mast compressor? Yes, the compressor will also be mounted within the sound dampening enclosure. II) ONAN Generator: Do you require an 18 or 20 KW generator? 18 KW. What are the sound dampening requirements of the commercial grade exhaust silencer? This is a standard option offered by ONAN. (See ONAN specs for DNAF Quiet Site enclosure).
