McDonnell Pediatric Research Building-Air Handling Unit Service Interruption 5/8-20/2023

A contractor will be cleaning a portion (the large vertical riser) of the supply air ductwork served by the laboratory supply air unit, AHU-1. This unit serves laboratories on the northwest side of the building (roughly half of the laboratory facilities in MPRB). This will impact all of the BSL3 suites in MPRB. To minimize the impact on the lab occupants, the contractor will be completing the work on an overnight schedule. The work will be completed on an overnight schedule as follows:

• Monday, May 8th: 9:00 PM through 7:00 AM the following morning.
• Tuesday, May 9th: 9:00 PM through 7:00 AM the following morning.
• Wednesday, May 10th: 9:00 PM through 7:00 AM the following morning.
• Thursday, May 11th: 9:00 PM through 7:00 AM the following morning.
• Friday, May 12th: 9:00 PM through 7:00 AM the following morning.

• Monday, May 15th: 9:00 PM through 7:00 AM the following morning.
• Tuesday, May 16th: 9:00 PM through 7:00 AM the following morning.
• Wednesday, May 17th: 9:00 PM through 7:00 AM the following morning.
• Thursday, May 18th: 9:00 PM through 7:00 AM the following morning.
• Friday, May 19th 9:00 PM through 7:00 AM the following morning.

Impact:
• During these work periods, there will be reduced exhaust airflow to all of the non-BSL3 laboratories in the building. No work should occur in the fume hoods during the work periods listed above.
• The supply air unit (AHU-1) for the northwestern half of the building will be off during the times noted above. Space temperature for these areas will be warmer than normal during the work periods listed above.
• The supply airflow to all of the BSL3 lab suites will be off during these outage times. No work may occur in the BSL3 laboratory suites during the work periods listed above.
