Note that the successful Contractor is responsible for submitting service requests to CL&P as soon as possible after commencement of work in order to expedite project schedule.

The pricing response form has been revised to reflect the outlined in this addendum. A copy of the revised form is included as an attachment to the addendum (One (1) page). RESPONSES TO QUESTIONS 1. Question: I was reviewing the drawings and I have a question about CL+P Metering for the 1200 amp service for the mansion. The CT Cabinet is to located by the CL+P transformer as shown on drawing and the one line draw doesn’t show a main breaker before the CT Cabinet, as this required by CL+P’s I+R book that the CT Cabinet needs to be cold sequenced. Will there be a main breaker be required? Response: Yes, a 1200 amp breaker is required at the pad mounted transformer location with meter in cold sequence. There will be a deduct alternate for having the CL&P meter in the basement of Lockwood Mathews. This requires CL&P access to the space along with remote metering capabilities for CL&P. 2. Question: Also there is a small service by the stone wall for some existing site lighting. What are we to do with this? Response: The existing site lighting meter service will be removed as per addendum drawing. There will be a 2” conduit with 2#8 +#10G for connecting the existing site lighting circuit back to the new gate house site lighting meter circuit. 3. Question: Can you provide an overview of existing operating hours of LMMM? Response: The Lockwood Mathews mansion Museum (LMMM) is open to the public, Wednesday through Sunday from noon to 4 p.m. Offices at the mansion may be in use Monday through Friday 9 a.m. to 5 p.m. Special events and tours may be scheduled at other times by special arrangement, including weekends. 4. Question: Can we remove the basement window to the left of the existing electrical services panel? Response: No. The existing window to the left of the existing service panel is to remain. 5. Question: Can we bring the new services through the existing window, rather than through the wall? Response: No. The new service is to come through the masonry wall, to the left of the stone steps when viewed from the exterior. Refer to SK1 included with this addendum for more details. 6. Question: Can we utilize the old boxes (circuit panels) to patch-in services (new service to existing distributions)? Response: No. Provide wireway to the right of the existing floor conduits and extend wires from wireway to new panel boards. 7. Question: Can you verify the measurements of the openings leading up to this space? (entry points from front of mansion to electrical room area) Response: The exterior entry door is approximately 38” wide. The masonry archway from adjacent space is approximately 37” wide. 8. Question: Are historical qualifications required to perform these services? Response: No. 9. Question: Can you verify the selected entry point into the building? Response: The entry point will be on the right side of the room when facing the electrical panel wall. From the outside of the building, it will be to the left of the existing stone stairs. Refer to SK1 included with this addendum for more details. 10. Question: Existing proposed entry point will be very difficult to restore due to: stairs, window well area, location of existing electrical panel. Response: The Entry point will be on the right side of the room when facing the electrical panel wall. From the outside of the mansion, the entry point will be to the left of the existing stone stairs. Proposed entry location will avoid existing stairs and window well. Refer to SK1 included with this addendum for more details. 11. Question: How are we supposed to install the new service in the same space as existing service without an extended period of disruption in services? Response: Please refer to the revised phasing notes on revised drawing E4.00. (Included with this addendum). If a wireway is installed on the right side of the electrical room, the existing floor conduits and wire can turn 90 degrees into the new wireway. From there the wires can be extended into the new panelboards, located to the left side of the window as well as on the adjacent interior wall. The new panelboards can be connected to the existing service switch to provide temporary power and allow for swinging over of the circuits. Once the circuits have been connected to the new panels, the existing panels can be removed and make space for the new switch and distribution. 12. Question: Based on MY observations of the surrounding, I would be my suggestion that the new services be brought into the area adjacent to the outside wall area. That area is open now and will also allow easier entry into the building as well as less disruption to the existing conditions; therefore it should be less expensive? Response: The Entry point will be on the right side of the room when facing the electrical panel wall. From the outside of the mansion, the entry point will be to the left of the existing stone stairs. Proposed entry location will avoid existing stairs and window well. Refer to SK1 included with this addendum for more details.
