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.
