[GOV RESPONSE RFI 003] No, a sign-in sheet will not be provided to contractors. Yes, consideration will only be given to Woman Owned Small Business (WOSB) firms.

[RFI 004] “The RFP clearly states that the Superintendent may not serve as the Quality Control Manager. Can the Superintendent or Quality Control Manager have other duties and serve as the Site Safety Health Officer? Or, will a separate SSHO be required? Three separate individuals.”

[GOV RESPONSE RFI 004] The Superintendent may serve as the SSHO for this project.

[RFI 005] “Part 3 Statement of Work/Project Program, Para. 2.1 indicates that the new medium voltage selector switch must be installed outdoors and secured on top of a concrete pad. Does the Government have a desired location for the new medium voltage switch?”

[GOV RESPONSE RFI 005] “The KTR shall determine placement of the new equipment after surveying site utilities. See attachment images “Aerial View - Project Location.jpg” and “Desired Equipment Relocation.jpg” for desired location.

[RFI 006] “Part 3 Statement of Work/Project Program, Para. 1.1 and 2.1 both indicate that there is an existing 750 KVA oil filled transformer located exteriorly west of Bldg. 339 to be replaced. Is this the same transformer identified in the Statement of Work as ‘Building 339 transformer (T34)?’ At the site visit it was indicated that this transformer was not to be replaced. Please clarify.”

[GOV RESPONSE RFI 006] T34 is to be replaced. T2 is not to be replaced. See attachment image “Aerial View - Project Location’ and “T34” for identification and location of transformers.

[RFI 007] “Part 3 Statement of Work/Project Program, 2.1 also states that the new transformer (T34) mentioned above be relocated to a new location. Does the Government have a desired location for the new transformer?”

a. ID This HV switch not shown on Single line provided? Is this switch to be relocated? If so, how does it relate to the single line circuiting?

b. Enclosed breaker – ID this breaker we believe this to be the main to building 339? Again not on the single line? Is this breaker also to be relocated to above ground. If so we need to know the location of the gear this breaker feeds as these secondary feeders will need to be replaced. Will need the distance for estimating feeder cost.

c. Secondary feeders verify wire size as not shown on any docs that have been provided?

[GOV RESPONSE RFI 023] See attachment “B339 Single Line Diagram – Conceptual.jpg” and as-built drawings “6363561-E16, 6363565-E20,” and “6363566-E21” for component and equipment identification.

*Note: Diagram shall be verified on the field. The components and equipment are believed to be configured as shown. Components identified are to be removed. Simplification of new replacement system is desired.

See attachment “T34 – Secondary Feeders.jpg” for secondary feeders size.

Contractor’s attachment is provided for reference via attachment “RFI 023.”

[RFI 024] “Also, can we have the government ID the location of MH4 (Verify that this was the manhole that was opened on the job walk.) If so, we request that the government provide pictures of the interior with the existing splices? Type of existing splice? Will the government require new J-bars at this location.”

[GOV RESPONSE RFI 024] See attachment “MH4 Location.jpg” and as-built drawings “6363565-E20.” Depth is believed to be approximately 10 feet but requires verification. Detailed images of interior of manhole would require a base wide power outage. The Designer of Record (DOR) will determine any required new design features.

[RFI 025] “There appears to be conduits entering the side of HVSS-10 can the government ID the source of these conduits again not identified in as-built documentation.”

[GOV RESPONSE RFI 025] See attachment image “B339 Single Line Diagram – Conceptual” and as-built drawings “6363561-E16,” “6363565-E20,” and “6363566-E21” for component and equipment identification.
