McCarran Airport – Terminal Three, Las Vegas, NV

McCarran Airport-Central Plant Upgrade and Phase Commissioning, Las Vegas, Nevada, 2005 – 2012

Project Description:

When McCarran International Airport’s $2.4-billion third terminal complex opens on June 27, it will mark the end of a decade-long string of big projects in the region. Touted as the state’s largest public works job ever, construction proved tricky with more than 100 contracting companies working simultaneously on multiple phases in close vicinity around a fully operating airport. Despite the size and complexity, the project still finished on time and on budget. All told, it was the largest expansion in the airport’s 64-year history, and brings the four-runway, 2,800-acre McCarran to final build-out at 117 gates.

Scope of Work:

TMCx Solutions provided the commissioning authority under the mechanical and plumbing contractor as their commissioning liason. There was four phases, pre-functional, start-up, functional and turnover.

Project Snapshot

  • Owner: Department of Aviation
  • Project Size:  2.3M sq. ft.
  • Construction Cost:  $2.4B
  • GC: Perini Building Company
  • Year of Completion:  2012


  • Air Handling Units
  • VAVs
  • Fan Coil Units
  • Unit Heaters
  • CRAHs

Challenges and Successes:

  • Issue: many of the return and supply fan status were not functional on the graphics.
    • Resolution: Honeywell had to replace faulty component within the panel
  • Issue: VAV boxes were not meeting setpoints, both heating and cooling.
    • Resolution: Issues resulted from heating valve signal being switched with cooling valve signal, valve set in wrong position so it would be at 100% when being commanded to 0% or bypass valves not being completely closed.
