REQUEST FOR SPECIFICATION CLARIFICATION

SPECIFICATION ITEM NO.: 405_____________________

PARAGRAPH / SECTION NO: All_________________

TITLE: Radar Magnetron Replace

QUESTION:

The first Line Item related to the radars is Item 405 which specifies the magnetrons are to be replaced yet the radars are not identified. We are then instructed to work in conjunction with Item 406.

The second item related to the radars is Item 406 which identifies the 10cm radar as a FAR-2127BB. The 2127BB is not a 10cm radar. It is a 3cm radar. Specifically, it is a 25KW X-Band radar. We would like to assume the other two radars specified as FAR-2117 are as stated, a pair of 12KW X-Band radars. Further, Part 7.1.2 specifies removal of the arrays from the antenna pedestals for preservation work. It is our experience that the arrays rarely come apart from the antenna pedestal without significant damage due to the use of aluminum chassis, stainless crews and little or no corrosion inhibitor during assembly. Finally, 7.1.4 calls for replacement of gear box oil and transmission drive belts. In nearly 40 years’ experience with Furuno radars, I have no recollection of an oil filled gear box or transmission drive belt in a Furuno radar. Furuno uses direct drive gear trains Respectfully, the spec writer appears to using a very old template for some other radar model in this instance.

Request an extension of the offer due date to March 21, 2018 due to the significant number of subcontractors on this project and other proposals currently in process.

ANSWER:

See amendment 3 for revised work item 0405 and 0406.
