Hi All, I am sure you are aware that 4 Colby Street experienced a power outage on Sunday morning. The outage lasted about an hour and also impacted the main campus. During that hour, National Grid was able to switch to one of our two back-up
circuits. The outage was caused by a cable failure in the vicinity of Harvard Street. They have since repaired the cable, but have not transferred load back yet. Upon inspection, they found evidence of cable deterioration. This particular section (from
the intersection of Main and Harvard Street to 4 Colby Street) dates back to the construction of 4 Colby Street (circa 1991).
National Grid has decided to replace this section of cable as soon as possible. In fact, some of the preliminary work began today. Most likely, they will begin to pull cable on Friday. Both 4 Colby Street and the main campus will
remain on the back-up circuit until this work is complete and tested. Most of this cable is above ground and the replacement is relatively simple. Closest to 4 Colby Street, however, the cable goes underground and into the switchgear located right off Harvard Street in front of 4 Colby. In order to replace
that section of cable, it will be necessary to arrange for a 6-8 hour electrical shutdown of the 4 Colby Street facility.
The preferred shutdown date is Saturday, July 23rd. If this date presents a particular hardship, please let me know as soon as possible. We have a little bit of flexibility. The alternate day/time would be toward
the end of next week (July 20 or 21 perhaps) starting at 5 or 6 pm and working through the night until complete. We do apologize for the inconvenience; this is an important opportunity to replace an aging piece of cable before it fails. Please note that the building generator will be available during the outage. Should you have questions, please
feel free to contact me. Betsy -- Betsy Isenstein Director, Facilities Technical Services Tufts University 520 Boston Avenue Medford, MA 02155 617.627.3704 p 617.627.3598 f |
