A4: POP will be adjusted, see revised SOW.

5. Question: The project site map does not show a GC laydown area. Can the VA confirm if certain area is proposed for laydown?

A5: Laydown area is to be coordinated with COR during pre-construction meeting.

6. Question: The project scope includes work in multiple buildings located all around the campus. Please, provide specific phasing of work to be completed. Is there any sequencing on what building, or floor has to be completed first?

7. Question: Provide site visit sign in sheet A7: Included with this amendment

8. Question: Does the project require an SSHO with no other duties on the project, per spec section 01 35 26? Can the SSHO and CP be the same person?

A8: Follow specification 01 35 26 for SSHO requirements. SSHO cannot be a CP for the subcontractors.

9. Question: Do the EM feeders on the project have to be run in rigid conduit?

A9: Rigid conduit is an approved raceway but not exclusively required. Reference Specification 26 05 33.

10. Question: Are stored materials allowed on site?

A10: Space is limited on the VA campus and stored materials will not be allowed on site out side of the laydown area provided.

11. Question: Per spec section 01 35 26, What qualifies for SSHO construction experience?

A11: Training requirements are outlined in specification 01 35 26.

12. Question: Page E-501,

a. Where is each type of ductbank required?

A12a: Duct bank details are standard in nature. As shown, duct banks shall be concrete incased with conduits spaced 3” apart and 3” from side of duct bank, minimum of 24” deep with warning tape placed 12” down form top of finished grade.

A15e: Changes will be addressed by COR and modification to the contract, if needed, by the Contracting Officer.

16. Question: Page E-001, General Electrical Note 22-L states that all electrical outages must be planned prior to construction beginning. This could significantly affect the duration and redundancy of visits to certain buildings if outages are not approved as planned. What solution will the VA provide if this extends the project duration and amount of labor required to revisit areas? How long does the VA expect to take to review and approve the outage plan before construction can begin?

A16: Outages required should be planned prior to the start of construction. The actual date the outage takes place can be adjusted within the POP due to personnel availability and environmental factors. Reference specification section 01 01 10SN for advanced notice of scheduling of outages.

b. Will the wires need to be un-terminated for the megger testing?

A19b: Follow proper procedure as documented in the instructions for the instrument being used.

c. Will testing need to be verified or completed by a third-party tester?

A19c: No, testing shall be done by qualified personnel as per the contract documents and a report submitted on the testing results confirming the feeders are operational and there are no issues.

d. Note 20 is unclear whether wires can stay terminated on OCPDs or if the need to be open. The note seems to contradict itself. Clarification on which route expected please?

A19d: note 20 is noting the requirements for the documentation of the feeder condition and the information to be gathered. The means and methods of the testing and information gathering is to be done with proper industry standards and procedures.

20. Question: Some existing flush mount panels listed for retrofits may be too small to accept a retro kit. What should the expected remedy be for these situations?

A20: If during contractor investigation a discrepancy is identified between existing conditions and the contract documents (drawings and specifications), follow contract procedures and submit an RFI.

21. Question: Procurement times in the electrical industry are very long at this point in time. With a POP of 315 days and construction period even shorter than that, some larger equipment can take almost a year to receive from submittal approval. What is the expected remedy in instances where equipment cannot be produced within the time constraints of this project?

A21: See answer to Q4.

22. Question: Will the drawing set be updated through the period of this contract, given that there could be construction bulletins and changes?

33. Question: Page E-115 and E-117, Key-Note 1 is located on this drawing, yet not shown on the drawing itself to highlight what panel(s) are affected by the note. Please clarify.

A33: all panels shown E-115, E-116 and E-117 as bold are to have the feeders replaced. Also reference on E-600

34. Question: There is no page E-116 located in the drawings. Is this correct?

A34: this drawing is located at the beginning of the electrical drawing set, page 12 of the combined set.

A: Drawings are based on the best available information at the time of survey and visual inspection. The below discrepancies have been reviewed and direction provided.

- There are no panel schedules for 6-A2-5 and 102-EUL-Q-B3.

A: See attached panel schedules for breaker sizes and quantity.

- 5-Panel L-2E seems to have an inaccurate panel schedule based on the one-line.

A: Panel schedule is correct. 100 amp breaker listed as “unidentified” in 5-Panel L2- E Section 2 is feeding new panel “5-Hall Panel”.

- 6-Main D BSMT seems to have an inaccurate panel schedule based on the one-line.

A: Elevator breaker in One-line and on panel schedule is 200A breaker. New panel schedule attached.

- 20-MD20B-1 seems to have an inaccurate panel schedule based on the one-line.
