About IMC
Ira McDonald Construction started as a small builder, founded in 1941 by Ira E. McDonald. His three sons – Larry, Dale, and Wynn – developed the company into a well-established construction management and general contracting firm.
Now moving into our third generation of leadership, we’re proud to celebrate over 80 years of success in the industrial, commercial, institutional, and healthcare sectors. We’ve earned a reputation for delivering smart, dependable construction solutions through repeat clients, referrals, and trusted relationships.
At IMC, we value clear communication and guide our clients through every step of the design and construction process. Our experienced team brings practical insight, technical excellence, and a collaborative spirit to every project, whether it’s new construction, renovation, retrofit, or restoration.
