What sets AEC apart

Design, construction, and operations mastery, in one partner.

Led by Dr. James Mark-Ige, Ph.D., P.E., AEC brings 35+ years of water-infrastructure leadership across all three phases of the water lifecycle. That end-to-end command means we understand not just how systems are designed, but how they are built, maintained, and operated in the real world.
