amendment_3.pdf

THE PURPOSE OF THIS AMENDMENT IS TO:

1. Provide answers to the following questions:

a. Question: Can drawings of the current foundation, including information regarding soil samples, be provided? I was onsite last week for the site visit and noticed the drawing in the packet on page 70 does not match the shape and dimensions of the actual area. Can drawings of the current machine area and sunken foundation area with detailed dimensions be provided?

Answer: Drawings of the foundation are provided as Attachment A to this amendment.

NOTE: this drawing is submitted as the existing foundation was furnished by Defense Industrial Plant Equipment Center (DIPEC) when the existing machine was installed. The Trident Retrofit Facility (TRF) cannot validate accuracy as historical documents are non-existent. Please also be aware that the dimensions shown on the foundation drawing are not representative of the overall maximum allowable area. Soil samples are not available.

b. Question: Can you provide names and contact information for companies that have done foundation work on the base in the past?

Answer: TRF has not worked directly with any contractors as most of our work goes through the Naval Facilities Engineering Command (NAVFAC).

c. Question: Do all installers and maintenance technicians have to be American citizens?

Answer: Yes. All must be U.S. citizens and possess the ability to prove citizenship. If they are not, or cannot prove citizenship, access will be denied. No exceptions.

d. Question: Section 3.3.16.8 calls for an analog hour meter. Is an electronic hour meter included in the machine control acceptable?

Answer: TFR prefers an analog hour meter.

e. Question: Will European Conformity (CE) machine certification for the machine be acceptable to meet the NRTL requirement?

Answer: No.

AMENDMENT NO.

f. Question: In reference to this RFQ I am asking if there is any plan to change the installation of the machine to another location. We do not believe that anyone can quote a machine the size that you are asking for in this RFQ and have it fit into the allowable space.

We cannot bid this even though our machine is a perfect match for the specification. The space is simply too small for this size of machine. This RFQ is for a machine that can turn a 10 foot diameter but the allowed space only has 5 feet on either side for the rest of the machine including chip conveyor, controls, covers, and auto tool changer. The height is also too small.

Answer: The available space has been verified with a change to the maximum allowable height as follows:

i. Length = 20’.

ii. Width = 26’2”.

iii. Height = 25’2”.

2. Update Purchase Description VIBB 16-25-1000 dated March 18, 2016 to now read as VIBB 16- 25-1000 dated June 9, 2016 (Attachment B) to reflect the following changes:

3.4. Size and Capacity; Table I Size and Capacity; Max Allowable Installation Space (L, W, H):

20’ L x 26’2” W x 25’2” H.

3. All other terms and conditions remain the same.
