A New Era of Training:
New Training Facility Opening Soon The new Training Facility will be ready for its first classes in Fall 2026. This major investment reflects our commitment to providing ongoing, long-term support for both Apprentices and Journeymen as they advance in their careers.
The facility is designed to improve technical education and ensure Apprentices have access to the tools, space and environment needed for high-quality learning which will prepare them for success on the job. The 44,000 square-foot state-of-the-art facility features modern classroom spaces and fully equipped workshop areas. Students will benefit from dedicated training areas for plumbing, refrigeration and air conditioning, fire sprinkler systems, and welding — each designed to simulate job-site conditions and support hands-on learning.
Some of the new features that were incorporated into the new Training Facility are a VRF (Variable Refrigerant Flow) Training Lab, expanded Backflow Prevention Lab, updated and expanded Fire Sprinkler Training Facility, Underground Plumbing Pit, and a Plumbing Layout Deck.
The VRF Training Lab features four major manufacturers. Each manufacturer's training station will include one 3-phase outdoor unit connected to multiple indoor units, one single-phase outdoor unit connected to multiple indoor units, manufacturer specific service and diagnostic software tools, television display monitors for live system operation, diagnostic and performance data.


The expanded backflow prevention lab will have a dedicated testing room and provide enhanced training opportunities for backflow assembly certification.
The fire sprinkler training facility has been updated and expanded to include new riser manifold training systems, a 5,000-gallon water storage tank, two-story mezzanine structure for elevated hands-on training projects which will allow apprentices and journeyman to gain practical experience with fire protection systems, riser installations, inspections, testing and maintenance procedures.
The one of a kind 25' x 25' underground plumbing pit simulates real-world underground piping installations which include underground sanitary piping layout training, the ability to pipe systems from the underground pit to the second-floor plumbing deck and full-scale residential and commercial plumbing layout exercises.
The plumbing layout deck will provide hands-on training for fixture installations and replacement, plumbing system troubleshooting and repair, service plumbing operations, drain inspection camera usage, drain cleaning equipment operation as well as underground and concealed piping locating techniques.
In addition to supporting Apprentices, the new facility will also offer Journeyman upgrade classes to ensure they can stay current with industry standards and continue developing their skills as our Trades evolve.
The Union and Trust Fund offices are projected to move to the new Aiea facility in 2028.
