With today’s advancements in technology, drones are becoming more and more useful in our industry. Some of the area’s where drone use is becoming prevalent, is in the Survey, Inspection and Construction classifications.

This work belongs to the Operating Engineers and getting our members ready for this new technology is important to us.

As a result, the Operating Engineers Training Trust & Surveyors Training Trust, have been working together, researching the use of drones in our industry and training our instructors to conduct drone training for local 12 members.
