MSI Construction, Inc. is a company with deep roots and vast construction experience in west central Indiana. MSI has evolved around a family business started in 1957 by Irvin M. Major, founder of the Major Lumber and Construction Company. The company was located just west of Clinton, Indiana on State Road 163, MSI Construction, Inc. is presently located at the Clinton Industrial Park, 2250 North Main Street Clinton

During the 1950's and 1960's Major Lumber and Construction Company was constructing public work and private projects. The company also began to specialize in large commercial and industrial buildings, including pre-engineered metal buildings which were becoming acceptable as a low cost and functional alternative to conventional material and design. In the 1970's the company was beginning to expand it's vision into the design and build market. With the business expansion into the general construction and build area, Irvin Major decided to change the company name to Major & Son's, Inc. General Contractors to reflect the primary operation of the company. Major & Son's, Inc. performed work for the U.S. Government, Corp of Engineers, State of Indiana, Local Government Agencies, Public Utilities, and Private Industry. Major & Son's, Inc. was a competitive bid and design-build contractor until 1994, when it's founder and president retired.
