1. Is the paralleling function required as called out in Specification 26 32 15, paragraph 2.22.3? This usually requires synchronizing equipment and communications between the permanent generator and portable generator for this feature to work. We see this as an either-or situation based on the interlocking breakers that are shown on drawing E-303. Please clarify.

There is no requirement for paralleling of generators. Both generators are to operate independently and shall be selected individually by means of the interlocked breakers.

2. Is the ATS required to be closed transition as per Specification Section 26 36 23, paragraph 2.1.11? Again, this also requires synchronizing equipment for this to occur. We see this as an open transition ATS. Please confirm.

A closed transition ATS is not required. An open transition ATS is acceptable.

3. Can you provide photos of all 4 walls in electrical room 115?

See attached.

4. Note 4 on drawing E-302 says the feeder between MTS and GCB-1 to remain and be re- used.

What is this being used for? New feeder shown as overhead and 2 conduits. Please clarify.

MTS/GCB feeder shall be removed and replaced.

5. Drawing E-302 - Key Note 4 states "the existing feeder between the mts and generator circuit breaker gcb-1 shall remain and be reused". Key Note 6 states "disconnect and remove existing feeder conductors from underground conduit. Cut existing conduit at both ends flush with slab and fill opening with epoxy grout." These notes contradict each other. Please clarify.

MTS/GCB feeder shall be removed and replaced.

6. Please confirm that it's understood that B564 will not have portable generator back up during the construction phases of the project once the MTS is removed.

That is understood by the customer. The customer requests to be informed ahead of time prior to removal.

7. Will we be able to perform any demolition of any existing equipment, conduits, wiring etc. that is not required for changing over to new installations during regular working hours Monday through Friday from 7am to 3:30pm?

Yes. All materials/equipment to be removed and that will not be required for the turnover for the new installation can be removed during regular working hours as long as it is not a critical system and could affect normal operations (unless express approval is provided).

The building manager has indicated that facility working hours are between 6 am and 2 pm on Monday through Friday and any work to be conducted outside that window (weekends included) must be requested so an escort can be provided. Requests must also be submitted a minimum of 5 days before the work is to start.

8. Generator warranty starts at time of startup/testing and not at the time of owner acceptance per manufacturer's warranty. Typically, other work is required including training, closeouts and final acceptance which may occur several months after initial startup. The owner typically requires a warranty from final acceptance. Please clarify if extended warranty is required to be covered under the cost of base bid to cover this gap or if NAVFAC accepts manufacturer’s warranty terms.

The standard warranty terms are acceptable.

NAVFAC accepts the warranty terms and does not require an extended warranty.

9. Will the Government provide site pictures?

10. Drawing E-402 - Will we be able to install the Permanent Generator (including concrete pad), GCB-1, GCB-2, Wireway, PGDS-1, ATS-1 and all associated pullboxes, junction boxes, conduit and wiring during regular working hours Monday through Friday from 7am to 3:30?

All equipment and materials that can be installed prior to turnover according to the phasing plan can be installed during normal working hours. The building manager has indicated that facility working hours are between 6 am and 2 pm on Monday through Friday and any work to be conducted outside that window (weekends included) must be requested so an escort can be provided. Requests must also be submitted a minimum of 5 days before the work is to start.

11. Drawing E-203 - In electrical Room 115 is there enough space north of the MTS on the east wall in order to install the new 30amp disconnects and transformer prior to removing the MTS? Please provide photos of all four (4) walls.

12. Drawing E-901 - MCC modification requirements states "contractor shall retain the services of the manufacturer's service group to assist in the modifications of the motor control center and perform field inspection, testing and training." Due to the age of the MCC we will not be able to retain the manufacturer's services. Will it be acceptable to retain a third party commissioning to satisfy these requirements?

It is acceptable to use a third party in place of the manufacturer service group. The third party must be well versed in the design, maintenance, and inspection of MCCs and related equipment from that manufacturer.

13. MACC RFP list bid bond required but does not show percentage/amount. Please provide.
