The Mouat Company, Inc.

Birmingham, AL

The Mouat Company, Inc. has delivered turnkey industrial facilities since 1924, originally as an equipment representative for the foundry industry before evolving into a design-build construction firm by the early 1970s. For more than 50 years, Mouat has designed and built foundry facilities, frac sand plants, and mineral processing plants across the U.S., Mexico, Europe, and Central Asia. Its fixed-price design-build model gives clients a defined project cost before contract award, eliminating the open-ended exposure common to cost-plus EPCM arrangements. Process design, 3D facility modeling, multi-discipline engineering coordination, and fabrication integration are all delivered under a single contract from concept through commissioning.
