Tribune Tower Facility Maintenance

About This Project


The Tribune Tower was in need of a third-party operations and maintenance company that would take over the facility maintenance of all the equipment that serves the building. Kroeschell’s long standing relationship with the Tribune dates back to the 1930’s, when we installed their first air conditioning system. Our continued presence and dedication to the building was a driving factor in their decision to make us their contractor of choice.


Kroeschell took over all the scheduled and unscheduled daily operation, maintenance and service calls for the HVAC, plumbing, electrical and lighting. Kroeschell staffed nine full-time, on-site engineers that worked in shifts to cover the facility 24/7. Our team provided service on the:

  • High pressure steam plant consisting of three 2,000 lbs per hour boilers, which were later converted to five low pressure water tube boilers.1 Includes maintenance on all auxiliary equipment.
  • Chiller plant with three centrifugal chillers (1000 ton, 850 ton and 500 ton)
  • Domestic water system
  • Building automation system with 11,000+ points
  • Life safety systems
  • UPS system, transfer switches and emergency generators
  • Fire alarm and sprinkler systems
  • All of the supplemental HVAC systems and equipment

1During this time, Kroeschell was also charged with replacing the three existing boilers from the 1960s. Kroeschell dismantled and removed the three (3) high-pressure water-tube boilers and replace them with five (5) new, low-pressure water tube boilers. The fully modernized boiler system allowed the Tribune to apply for and receive an energy savings rebate from the local gas company for $234,629.85.


Kroeschell maintained a close partnership with the Tribune Tower providing a high level of flexibility, responsiveness and precision in our performance.

With the support from our additional divisions, including in-house mechanical engineering and service teams, Kroeschell provided operation and maintenance that went beyond the requirements. We were able to diagnose and repair complications quickly, accurately and cost effectively.
