The humidifier serving NTA 454/463 needs to be re-piped. The steam service for all of the NTA 4th floor trim humidifiers will be shut down for approximately 2 hours during this outage which is expected to have only a minor impact on the space humidity for the 4th floor rooms. NO work will be allowed in NTA 454/463 ABSL3 lab during this outage.
UPDATE: The contractor encountered an issue with the existing steam piping and needs additional time to complete the humidifier installation for NTA 454/463.
We thank you for your patience and understanding at this time.
