1. Drawing E14-01 “One Line Diagram” (Add. #1) and E14-02 “Electrical Site Plan” shows a POC at the “New CL&P Primary Metered Pole”, a new pad mounted service transformer, and a new pad mounted metal enclosed switchgear. Drawing C14-11 “Plan and Profile” shows the same POC but shows “Switchgear and Meter Vault Pads”. No service transformer is shown at this location. The one line and site plan reflects the metering at the CL&P pole but it appears C14-11 is calling for metering near the switchgear. Who will provide and install metering and where will it be placed? Will a new drawing be issued that shows the location of the service transformer on drawing C14-11? The metering is on the pole, per E14-02. The pads on E14-02 are as designated. Coordinate w/CL&P.

1. Specification section 16271 “Pad mounted Transformers” specifies the requirements for the 3000KVA service transformer. Will another section be issued for the building transformers? Refer to Add # 1.

1. Drawing E14-02 shows (2) 5” conduits for the electric underground. The “C” drawings show (4)-5” PVC concrete encased electric. Please clarify quantity on electric conduits in duct-bank. Provide (4) - 5" PVC concrete encased conduits.

1. E14-02 shows #4/0, 15kv with #4. Is this required in one conduit? If the requirement for conduits is 2 or 4 we did not find any information that reflected how conduits were used for primary cable circuits and how many were spares. #4/0, 15 kv with #4 is routed in one conduit.

1. Drawing C14-14 does not show new transformer pad locations at Proposed Conditioned Warehouse Building, Existing FMS Building, and Proposed Shower/Latrine Building. New transformers are shown on drawing E14-01 for these buildings. Will a new site plan drawing be issued to show locations of new transformers? Also, will a new site plan drawing be issued to show if the transformer at the Existing FMS Building will be changed out to a new transformer in the same location? No notes or information is provided (new or existing) on this plan for primary feeds or transformers. The three pads are shown on C14-14, however are not called out. They are provided by another contract.

1. There is a new transformer pad “4 X 4 Concrete Transformer Pad” shown on drawing C14-14 near a field parking lot area Northeast of the Proposed Multi-Classroom Building. This transformer is not shown on drawing E14-01. Will this transformer be required and if so what will it feed and what are the specifications? Provide a 75 kv pad mount transformer per spec 16271 at this location.

1. There is no drawing or specification that show the primary or transformers for the buildings being three-phase or single-phase. Please clarify. 3 phase , refer to voltages on drawing E14-01.

1. Drawing C14-14 does not specify exact requirements for secondary building feeds. There is a couple of connection notes but further requirements are needed. Two buildings show to be existing and three buildings are shown to be new. However, no secondary feed requirements are shown new or existing. Secondary feed is only required at Bldg P110. The others are in other contracts.

1. Bid Item No. 0002 requires pricing for communication wiring and telecom feeds. The “C” drawings require (4) 4” Telecom conduits. However they do not show any cable requirements. Please specify cabling requirements for Telecom. Communication wiring and telecom feeds are to be provided by the owner.

1. Drawing C14-14 shows Telecom feeds to Proposed Multipurpose Classroom, P110, and Proposed Conditioned Warehouse. This drawing does not show Telecom conduit for the other two buildings. Please specify conduit requirements for these two buildings. Please specify Telecom wiring for all five buildings. The other two buildings, (FMS and Shower/Latrine) are in another contract. Telecom wiring specs are per the owner, pull ropes are to be provided.
