15 SOW Section

1.0 Project

Description, para Utility Outages, page

The SOW states, "Extended outages may require temporary power.". What specific time parameters constitute an extended outage? If an extended outage requires temporary power, which building systems will require power?

I would consider an extended outage as an outage length that would impact other building systems and cause damage to the facility (i.e. no heat in winter, causing pipes to freeze) or an outage length that is unable to be scheduled around the normal building mission/occupancy.

16 SOW Section 33 71 02, para. 3.5.4 Jacking and Drilling Under Roads and Structures, Is directional boring acceptable? Will the use of HDPE duct for the raceway through the bored pathway be acceptable without the use of a steel casing?

No, conduits shall be installed in trench and concrete encased.

17 SOW Section 33 71 02, para. 3.5.4 Jacking and Drilling Under Roads and Structures, The SOW states, "Conduits to be installed under existing paved areas which are not to be disturbed, and under roads and railroad tracks, must be zinc coated, rigid steel, jacked into place." Will the Government please provide clarity as to which areas are considered "not to be disturbed" as it pertains to the scope of this project?

Areas not to be disturbed as it pertains to this project are roads and railways not owned by Navy or environmentally controlled areas. This should not be applicable to this project.

18 SOW Section 33 71 02, para. 3.14.1.1 b(2), Medium voltage cables, electrical tests, Contractor suggests that existing medium voltage cabling be hi-pot tested prior to splicing said cabling to new cabling. This will avoid splicing to a cable that may be on the verge of failure. Please confirm that if this situation arises a maintenance hi-pot test should be applied to the existing system cabling prior to splicing.

Splices are not allowed on the 12.47kV system. All 12.47kV cable junctions shall be made above grade in pad mounted sectionalizer pedestals. A maintenance hi‐pot test is not required prior to splicing to existing cable but is required after splicing to existing cable.

19 SOW Section 26 12 19.10, para. 3.5, Foundation for Equipment and Assemblies, Please confirm it is permissable to utilize existing concrete transformer pads as long as dimensions are appropriate for new transformer.

As long as existing concrete pads meet the size and structural requirements for new transformers, and are not showing signs of failure, they can be reused.

20 Part 4 Minimum materials, engineering, and construction requirements, G20 Site Improvements, In the interest of causing less disruption to Navy functions and to preserve existing hardscape, is it acceptable to utilize portions of existing medium voltage duct bank for new system cabling?

Existing medium voltage duct bank can be utilized for new system cabling. Emphasize that 12.47kV circuits are not allowed in manholes.

21 SOW Part 4 Minimum materials, engineering, and construction requirements, para. G40

1.3.6 Factory

"The government reserves the right to witness all factory testing." Please confirm travel costs for Government representatives for factory testing will be borne by the Government.

Correct, if Government chooses to witness factory testing, Government will pay for travel cost of Government employees.

22 SOW Part 3 Statement of Work, para.

Analysis and programming, Please confirm this analysis is for the entire mainside

34.5 kV and 12.47 kV systems as opposed to only the systems to be physically altered through this scope of work.

Correct, per the RFP analysis shall include all 34.5kV and 12.47kV circuits on mainside, whether altered under this contract or not.

23 SOW Section 33 71 02, para. 3.5.9.1, Connections to Existing Concrete Pads, Page

If applicable, please provide construction as-built drawings from the installation of applicable existing switches and transformers.

The existence of construction as‐built drawings for existing switches and transformers is unknown, assume they do not exist.

24 SOW Section 33 71 02, para.

3.14.1.2(b), Low voltage cable, 600 volts, Electrical tests, page

Will the Government please confirm if insulation resistance testing is required on existing secondary cables prior to connecting existing secondary cables to new transformers?

Yes insulation resistance testing is required for existing secondary cables prior to connection to new transformers.

25 SOW, Part 4, page 14, para G401006

Paragraph states splices are required. However, Part 3, SOW/Project Program, page 2, Demolition states:

Provide 34.5kv splices in manholes 1027, 1028, and 1034 to bypass unneeded cable for removal of building taps. Which is correct?

Splices are not allowed on the 12.47kV system. All 12.47kV cable junctions shall be made above grade in pad mounted sectionalizer pedestals. Part 3, Demolition requires 34.5kV splices to the existing cable to bypass building taps.

26 Solicitation,Off er, and Award Block 11.

Request 90 days be added to the performance period. With the two 21 day design approval periods (50% and 100% reviews) pluse required design time 365 days is not enough time to design, procure long lead items, then construct.

90 Days will be added.

27 SOW, Part 3, Page 2, Demolition

Paragraph states that existing 34.5kv cables in manholes 1027, 1028, and 1034 are to be spliced together after the switches are removed. Is the intent for the resulting M30-M40 tie to be an alternate subtransmission loop path? If so, the existing relays at M30 and M40 for that cable loop need to be replaced with line differential relays. This also involves SCADA work. Is the replacement of the existing overcurrent relays with line differential relays required?

Correct the intent is for the resulting M30‐M40 tie to be an emergency 34.5kV subtranmission loop. No the replacement of the overcurrent relays and associated

SCADA work is not part of this project.

28 SOW, Part 4, G20 Site

Improvements.

Our experience at Great Lakes is that all backfill in paved areas needs to be flowable fill. Is that still a requirement?

Regardless of fill type used it must be able to meet compaction requirements. Type of Fill also varies depending on means and methods employed.

29 SOW Part 3 SOW, Chapter 1.0, para Analysis and Programming, SOW page 24

Please clarify the requirement listed in RFP Part 3, 1.0, paragraph “Analysis and Programming” to provide a complete coordination analysis, short circuit analysis and load flow analysis of the 34.5 KV and 12.47 KV electrical distribution systems on Naval Station Great Lakes mainside."

Or does this RFP include performing the short circuit analysis and load flow analysis for the complete existing 34.5 KV and

12.47 KV electrical distribution systems for the entire

mainside of Naval Station Great Lakes?

Per the RFP analysis shall include all 34.5kV and 12.47kV circuits on mainside, whether altered under this contract or not.

30 SOW Part 3 Statement of Work, para1.0 Building load analysis , page 23/185

Please confirm in case of building load analysis found unbalance of phase distribution, contractor need to revise and change/alter circuits feeding via panel through this scope of work. Does the contractor need to provide record drawings for these changes?

The intent of this contract is not to correct unbalanced building loads, but to appropriately size the new transformers to the actual building load.

31 General, scope Can the Government provide as builts for the buildings that the power feed serves along with any available as built drawings, utility maps, or existing conditions data for the surrounding area in which the feeder will be installed?

The availability of building as builts is unknown. Refer to RFP Part 6, Attachment G for utility maps and existing conditions.

32 General, RFP Based on the current COVID pandemic conditions and subsequent limitations on businesses for collaboration and coworking, will the Government extend the proposal due date by 3 weeks? This will allow offerors additional time to collaborate with teaming partners considering that most teams are working remotely which decreases efficiency on a collaborative proposal effort such as this.
