The Proposal due date is February 21, 2019.

1. QUESTION: In discrepancy with the Specifications Manual’s Table Of Contents Section 00 01 10 that states: “Division 04 – Masonry (Not Used,)” the Specifications Manual includes the following four Masonry Sections:

Masonry Mortaring 04 05 13 Masonry Grouting 04 05 16 Unit Masonry 04 20 00 Cast Stone Masonry 04 72 00

Verify whether the aforementioned four Masonry Specification Sections are applicable to the referenced project as the Drawings and Drawings Notes do not show or indicate any masonry scope of work at the referenced project.

ANSWER:

There are no new masonry elements included in the scope of this project. The included 04 Masonry specifications will thus not be used. They can be considered for reference only.

2. QUESTION: The elevation drawings indicate that the design shall be a unit substation design, not a pad mount design, since there is a primary fused disconnect switch and secondary 4000A breaker closed coupled to the transformer as part of the elevation drawings. The specs indicate otherwise as it specifies as pad mount transformer design. Please clarify if unit substation design is required or padmount? If unit substation, a revised spec would also be needed since the one provided is specific to pad mount features.

The elevation drawings also indicate that the transformer rating have fans, which seems to indicate a unit substation design as well rather than a padmount design. Please clarify.

ANSWER: 1. The Transformers C1 & C2 are Unit Substation design. See attach Section 26 11 16 Secondary Unit Substations.

2. Yes, Unit Substation designed. The rating of the transformer is 2500KVA AA / 3325 KVA FA. Drawing E-602 Elevation is diagrammatic, showing the connection from primary to transformer and to secondary section.

3. QUESTION: Spec 26 12 19, section 2.4 indicates the requirement for internal oil immersed bay-o-net fusing. This is not possible at the rated kva of 2500 and voltage of 4.16kv combination due to fusing not being offered as this high of an ampacity. For proper protection, a fused disconnect switch external to the transformer would be required and is what is indicated on the elevation drawings. Please clarify

ANSWER: Yes, follow the drawing E-602. Refer to Medium Voltage Fusible Switches Section 26 13 16. See attach specification Section 26 13 26

4. QUESTION: For the new conduit runs from the Transformers to the J-Boxes, will expansion couplings be required in the conduit run? The prints do not indicate if there is an existing building expansion joint between these points.

ANSWER: Expansion Couplings are not required.

5. QUESTION: On sheet E-801 Detail 3 “Typical conduit support detail” shows a high Density Polypropylene Plastic Block to be used to anchor/support the 4”rigid 24 way conduit rack. All the suppliers I have contacted state, the ones they carry are not intended to be used in this application. They are intended to be used for roof top application with fewer and or smaller conduits. Can you give us a manufacture that makes a product that can support the weight and cable pulling tensions that will be encountered?

ANSWER: The High Density Polyprolene Plastic Block is for roof use. “Midland Plastic” Per manufacture representative. This block cannot support the 24 – 4” conduits. It will sag even if the spacing is 8’-0”.

Provide a reinforce precast concrete base support for details on 1 & 3.

6. QUESTION: The specifications (26 05 19-3 para. 2.4) allow for THHN or XHHW-2 insulation. XHHW-2 for isolated power systems. Can the 500MCM be THHN?

ANSWER: No. Feeders shall be XHHW-2 500KCM (from Transformer to Switchgear) THHN shall be for branch feeders (from Switchgear to Distribution Panel)

7. QUESTION: Please confirm this project does not require the Prime Contractor to Supply a Commissioning Agent

ANSWER: The Prime Contractor does not need to provide a Commissioning Agent.

8. QUESTION: “Our last job at Hines VA, in 2017/18, all of the excess earth spoils were hauled and placed in an onsite stockpile, as the earth was determined to be non-CCDD acceptable. Do excess earth spoils need to be hauled off site? Has existing earth on this project been tested for CCDD acceptance? Who is responsible for the CCDD acceptance testing?”

ANSWER: 1. Contractor to remove excess earth spoils from campus.

2. Soil has not been tested for CCDD acceptance.

3. Contractor is responsible for CCDD acceptance testing.

4. Contractor shall assume all spoils have high iron content.

9. QUESTION: “Do Past Performance Questionnaires need to be submitted, and if so, will the Government provide the required form?”

ANSWER: While the Government may elect to consider data from other sources, the burden of providing detailed, current, accurate and complete past performance information rests with the Offeror. The government will not provide Questionnaires.

10. QUESTION: Will you provide the current coordination study on the gear and facility?

ANSWER: No. There is not one available.

11. QUESTION: Drawing E-602:

1. Are keynotes #1, and #2 to be included as part of this project?
