61 -- DIESEL GENERATOR SETS SOL N68936-98-R-0113 DUE 042898 POC Janelle M. Etoch, Contract Specialist, (760) 939-9669 This is a modification to a combined synopsis/solicitation printed in the 13 April 98 edition of the CBD. The original synopsis was a two-part synopsis. The purpose of the modification is to extend the closing date for receipt of offers and to answer questions submitted in response to the combined synopsis/solicitation The closing date for receipt of proposals is being extended to 28 April 98, 3:00 PM local time. The following questions and answers are being provided: 1) Question. Trailer specifications require vibration isolators between generator set base tank and trailer. What kind are we required to install? Pad type O.K. There is usually none provided because these isolation pads are between generator skid and frame. Answer. Isolation pads between generator skid and frame are satisfactory. 2) Question. Trailer specifications require that the trailer weight capacity must exceed weight of generator set and fuel by 15%. Is this correct or do you need a trailer that can handle the weight of generator set and fuel with 15% capacity left? Answer. Weight capacity of trailer must exceed weight of generator set assembly with all fluids at maximum levels with a minimum of 15% capacity left. 3) Question. We have reason to believe these trailer mounted generator sets currently exist. If so, who is the manufacturer and what is the make and model and are there drawings, specifications or other documents available? Answer. It is NAWCWPNS intent to procure units in which all components are commercially manufactured and mass produced providing us with a unit that should remain serviceable for years to come and not end up with special built one of a kind units that are obsolete right after they are manufactured. The requirements are all very basic and should be easily met by any manufacturer of generators. Requirements have not been tailored to any one manufacturer. If an offeror has units or options available that they think make their units more suited to our requirements and operational conditions, the offeror may provide documentation and pricing for those units and options. 4) Question. Due to the lack of specificity in the solicitation, it is therefore our conclusion that you are granting us a great deal of latitude in meeting the general specifications that are listed. Is this conclusion correct? Answer. NAWCWPNS has identified its minimum requirements and operational conditions and is giving the manufacturers the opportunity to propose units they feel are best suited for our needs. We are looking for common off the shelf units which our research has shown are available from several well known manufacturers. 5) Question. Do any dimensions or specifications exist for the trailer beyond what was listed? Answer. No, it is our impression that generator manufacturers typically provide trailers that are designed to carry their generators. For our application, minimum specifications have been provided and durability is a major factor. 6) Question. We are concerned that without more specific knowledge of what type of gauges, plugs, etc. that are desired we may be unable to perform to the delivery schedule if suddenly it is determined by NAWCWPNS that a component we desire to use is incompatible with your other systems. What is NAWCWPNS position on this type of scenario? Answer. If the offeror does not have a standard configuration offered, (2) 115 volt, 20 amp duplex outlets and (2) 115 volt twist lock outlets are desired. We will install our own three phase outlets. 7) Question. What type of paint and color is desired for the trailer and generator enclosure? Answer. Manufacturers standard colors are acceptable. White would be the color of choice but not required. The most durable finish type would be the most desired. By giving minimum specification requirements and operation conditions we are giving the manufacturers the opportunity to assess our needs and use their expertise and knowledge to provide units and options available which are best suited to our requirements. All other terms and conditions remain the same. (0114)
