5 MLK – Modular Mechanical Penthouse

5 MLK is a mixed-use, 17-story building with 220 apartment units, 120,000 sq. ft. of office space and 15,000 sq. ft. of retail space.

JH Kelly worked with in-house designers to fabricate a modular mechanical room for the penthouse level of the tower.  We fabricated the steel support structure, dressed out modules with pipe, valves, insulation and control wiring.  The finished product were 7 modules that had flanged-connections.  After being fully assembled and tested, the modules were broken down, flown to the 17th floor and placed on skates to move it to its final position.


  • 88,225 pounds
  • 7 modules
  • Pumps, Heat Exchangers, Benchmark Boilers, VFDs

This process saved approximately 3 weeks of schedule time as work was done concurrent with other phases and arrived on-site fully assembled, and installed as soon as the space and other trades were free and clear.
