Resolution 21-3892 That the Administration respond to educator and parent concerns regarding building maintenance and capital improvements for the Winter Hill School. The concerns expressed in this letter were addressed and resolved by DPW. Below is additional information to expand on what happened then and how DPW is addressing the issue moving forward:

CITY OF SOMERVILLE, MASSACHUSETTS DEPARTMENT OF PUBLIC WORKS KATJANA BALLANTYNE MAYOR 3 The Winter Hill Chiller had a leak that was apparently ignored or overlooked by the previous HVAC contractor. Their method of dealing with this was to simply add more refrigerant and oil at the beginning of each cooling season. Our new contractor JCC, makes proper repairs to our equipment. This project was expected to take one week to complete, which would have kept us on schedule for our normal June 1st cooling season start up. JCC started recharging the system only to discover another leak. This time in the shaft seal. This was undoubtedly the major cause of the delay as the part was not readily available and was a “long lead time item”. In the meantime, DPW installed more than 18 indoor air conditioners and modified windows to allow for proper exhaust. We also strategically placed box and post mounted fans throughout. This provided relief in most areas, but certainly not all. The DPW has reacted to this by starting the turnover process a month earlier than normal. For instance, this year we will start prepping our systems in April.
