This Addendum, applicable to the work designated herein, shall be understood to be and is an Addendum to the contract documents and, as such, shall be become a part of and included in the contract.

1. Please see attached April 29, 2025 Pre-Bid Meeting Minutes and Attendance Sheet. The Pre-Bid

Meeting Minutes shall become part of the contract documents.

Drawings:

1. None.

Specifications:

1. None

Contractor Questions:

1. See Pre-Bid Meeting Minutes for questions and responses.

2. Do we need to include Portable Generator Back up for the entire building during the shutdown of the electrical service, and will the shutdown take place when the school is on vacation. What would the KW be needed for the full building back up; do you know their PEAK KW DEMAND?

A. No, we do not need portable generator backup. We will not be shutting down the building as part of this phase. This utility transformer phase is getting a new primary feeder, utility transformer, and secondary feeder to the building in preparation for the switchboard replacement phase. The switchboard replacement phase we will be shutting down the building to demolish the existing inside utility transformer, connect the new utility transformer to the building, and replace/refurbish/refeed the switchboard.

3. Two locations in the drawings it mentions manhole installation, Dwg. E-001, Electrical Specifications Note D-1b and Dwg. E-501, Detail 7, Note 2; can you provide specs or installation details for the manholes.

A. We don’t have manholes included in the design drawings between the transformer and the building for this length of run. Ignore E-001 specification D-1b reference that applies to slope duct from a high point in runs between two manholes to drain in both directions that is not included in design. Ignore the E-501 detail 7 note 2 reference to manhole construction drawings not included in design.

4. Can site utility survey quality level A be reviewed by Dewberry as engineer? Is there any information on existing utilities?

a. Yes, we can review the utility survey plan from the contractor with the location of utilities and depths along the path of installations. We do not have information on the electrical feeder into transformer vault and believe there is at least water, sewer, and storm piping in the area.

b.

c.

5. Can permit fees be excluded from base bid and the $5,000 construction contingency used for the fees?

A. Yes

6. Does Town of Smithfield allow precast concrete transformer pads to match detail, such as allowed by Duke Energy?

A. Yes, if it matches the specifications for the concrete pad in the transformer detail.

Contractor to submit for approval.

7. What is Town of Smithfield contact information?

A. Jeff Stewart – 919.915.0933

8. For the alternate for concrete encased duct bank, does the concrete need to be one pour or can sections be poured and tied together with rebar?

A. Both are acceptable.

9. What testing is required for add alternates for providing conductors?

A. Perform cable insulation testing (such as Megger testing).

B. For feeder current-carrying phase conductors and neutrals: test the insulation resistance with respect to ground for one minute. Cables rated for 300 volts shall be tested with 500 volts DC and cables rated for 600 volts shall be tested with 1000 volts DC. All insulation resistance data gathered shall comply with manufacturer’s documentation; if documentation does not exist, comply with the values found in Table 100.1 in the

ANSI/NETA ATS-2009.

10. Should we include conduit from transformer primary elbow to conduit below asphalt?

A. Yes

11. Should we include the 6 stub ins into the existing utility transformer room from the junction box at the building wall with the base bid or alternate for conductors?

A. Include with the alternate for conductors.

12. What is the asphalt thickness?

A. Unknown. Assume full depth patching to match existing of minimum traffic level 2 with poor subgrade resulting in 2” asphalt surface layer, 2” asphalt upper binder layer, and lower binder layer of compacted 3” asphalt binder layer or 6” crushed aggregate base course layer.
