The (5) tier, 15th floor Pressure Reducing Station at North Central Bronx Hospital provides usable steam for Operating Room climate control, humidification of patient wards and autoclave sterilization. The facility only allowed one tier to be worked on at one time and only for 8 hours a day. In other words, once a tier was taken down, it had to be put back into service by the end of the day. Not easy when dealing with 14″ high pressure steam lines! We were able to accomplish the job ahead of schedule leaving the facility very happy with the results.
