SPM4A8-16-Q-0130 Amendment 0003

Amendment is issued to update the following:

The following has been removed from the Purchase Description: 3.6.2 (d) Hoist. An electrically operated 2 speed hoist for lifting work pieces onto the work table shall be furnished. The hoist unit shall be floor mounted or machine attached. The hoist shall callable of lifting 3,000 lbs. The hoist and related equipment shall comply with the Navy Crane Center Regulations and requirements. The Government shall provide the Navy Crane Center Regulations and requirements.

Salient Characteristics for VIBB 16-20-1200 dated August 2, 2016 will now be replaced with Salient Characteristics for VIBB 16-50-2115 dated October 26, 2016 (attached).

Questions:

(1) Can we have a plant layout showing the dimensions of the existing foundation at the location where the new machine will be set?

Answer: See attachment for copy of the footer

(2) What is the trade name and specification number of the paint we must put on the floor where the wall is removed?

Answer: Contractor will be required to use a variety of Tennant paint coating materials for all floor painting. ECO-HTS, ECO-MPE and ECO-Hard-N-Seal will be primary coating materials for the shop area;

however, other Tennant floor painting products can be used if approved by the government POC.

Coatings shall not have a lead content over .06 percent by weight of nonvolatile content. Coatings shall not contain zinc-chromate or strontium-chromate. Materials shall not contain asbestos, mercury, or mercury compounds. Coatings as applied will have VOC limits below 350 g/l for primers and below 420 g/l for topcoats.

(3) What is the existing electrical supply rating to the existing machine that will be taken out?

Answer: 300 amps

(4) Removal of non-load bearing wall. (95’ long x 32’ tall) – what material is the wall? Concrete block or wood?

Answer: The wall is concrete block.

(5) Existing floor where the machine will sit. Is it concrete or reinforced concrete? What is the depth?

What is the soil compaction underneath?

Answer: The floor is 3 feet thick reinforced concrete. It held a large Vertical CNC lathe. It should be more than adequate for this grinder

(6) Placement of the new machine. Is the area accessible without moving other machines?

SPM4A8-16-Q-0115 Amendment 0002

Answer: That will depend on your grinder and the way it is shipped. Should be enough room.

(7) Is a foundation required for this machine? We were told during the site visit that that we do not need to supply a foundation for this machine as they are removing a machine where the new grinder will be located at. The current foundation is more than adequate to accommodate the new grinder. Can you please confirm that a foundation for the new machine will not be necessary?

Answer: Based on the attachment provided, the size of the machine the foundation was constructed for a larger machine, therefore it does not appear that this project will require a new foundation.

No other changes to the original solicitation or amendment 0001 have been made.
