9/10 of

Phase 1 notes indicate a start date of 14 MAR 2022 and a completion date of 02 DEC 2022 while indicating to complete phase 2 work to the maximum extent possible, prioritzing substation 6 during phase 1. Phase 2 notes indicate a completion date of

31 MAR 2023.

However, the solicitation indicates an overall contract duration of 486 days and a planned NTP of 22 April 2022 which would shrink phase 1 and adds 5 months on the backend of phase 2 completion milestone date.

Please clarify phasing dates and milestone expectations that match the overall POP of the solicitation.

Please refer to the updated solicitation documents issued on Amendment 0002 detailing a 365 day period of performance with planned NTP on 22 April 2022.

Phasing and Milestone dates of 02 DEC 2022 and 31 MAR 2023 are confirmed. POP will extend beyond the construction completion of milestone 2 to support contract closeout submittals.

REUIREMENTS

FOR PHASE 1

note 1.1 states that MV feeders from SLD-1 vault to LC22, including ductbanks, shall be complete by the end of phase one which is contradictory to G- 103 & G-105. To what extent is the LC22 MV feed required to be completed by the end of phase one and does this include installation LC22 vault, switches, transformers and switchgear?

The MV feeders must be installed from SLD-1 vault to load center 22, including the construction of ductbanks, during Phase 1. The construction of LC22 must be complete to the point where outages on the MV feeders will not be required during Phase 2.

Portions of LC22 construction that do not require outages on the MV feeders are permitted to be completed during Phase 2. Refer to Attachment Amendment 0003_Sheet ES507, General Sheet Note 8, which requires the Heat Trace system to be installed during Phase 1.

This system must be permanently fed from LC22 and serves all three berths. In order to accommodate long lead time equipment, and permit portions of LC22 construction to occur during Phase 2, the heat trace system must be powered, temporarily, from LC10 until permanent power is established from LC22.

Coordinate with the Contracting

Officer for the exact temporary connection location at LC10.

Temporary power conductors must be routed through the new 14W ductbank between LC10 and the above grade utility duct (AGUD) and within the 6W ductbanks embedded in the AGUD. Extend the Phase 1 boundary of the construction of the AGUD to include the installation of the Heat Trace system equipment.

The heat trace circuits required to serve Berths 6A and 6B piping must be installed and operational during Phase 1.

Provide an extension of the concrete light pole base at Station 5+00 to accommodate the heat trace transformer.

Provide 2" conduit between the communications vault at Berth 6B and the heat trace enclosed circuit breaker. Provide 2" conduit between the industrial power station vault to the south of Station 5+00 and the heat trace enclosed circuit breaker.

Refer to additional information on revised Sheet

ES507.

When cross referencing drawings MA101, MA501, MA502, & CU501, at each HPA service riser you would have a 1" valve on each side of the 1" x 1/2" reducing tee, two inline 1/2" valves on the riser inside the utility duct, and then two 1/2" inline valves on the aboveground service connection.

Please confirm the two 1/2" inline valves on the riser inside the utility duct are drawn in error and not required.

The two, 1/2 inch valves on the riser within the duct are not required.

Follow Detail C3 on MA 501 for the service branch outlet within the concrete utility duct. Follow Detail A2 for the HPA service station piping above the utility duct cover.
