Project Description:

The new Phoenix Children’s Hospital West Pavilion addresses a number of service lines in need of expansion, especially the Emergency Department.

The building also has a significant Oncology Department, a major hospital lab and includes the hospital’s administration department.

Scope of Work:

TMCx was retained by PCH to perform commissioning services per the ASHE Health Facility Commissioning Guidelines.  This included design phase reviews and coordination with the design and construction teams.

Challenges and Successes

  • Issues: During pre-functional inspections, it was identified that there was no local means of disabling the AHU’s VFD, as it is located in electrical room approx. 100 ft. away.  The units were also not shutting down via fire system, as required by code

          Resolution: As a result, the VFD was relocated in the field due to conditions. Intent was that NEC code was to be followed and local disconnect to be provided adjacent to unit when drive was relocated. The contractor installed proper safeties and smoke detection and control for proper shutdown.  The Units are now able to properly operate with all required safeties, per the design documents.

  • Issues: The Fan Coils were found no to have secondary condensate pans and water monitoring as shown on both Mechanical drawings and Controls submittal. 

          Resolution: As a result, condensate and water level alarming was installed on the wall mounted electrical room unit, per the EOR response. Installation of condensate and water level sensor reduced the possibility unit overflow due to failed condensate pump.
