G. I. Construction began doing business in 2012 as a general contractor, but our roots go back more than 40 years. In 1972, Guarantee Interiors was formed as a division of Guarantee Electric to meet the increasing demand for a full service contractor for drywall, ceilings, flooring, painting and millwork. Under the direction of Robert A. Farrell, Guarantee Interiors achieved rapid success and quickly emerged as one of the top interior construction contractors in St. Louis.

In 1993, Mr. Farrell purchased Guarantee Interiors and incorporated under the name Guarantee Interiors, Inc. The company continued to grow steadily, and repeat business from our customers eventually led us to offer general contracting services.

Today we have completed more than 10,000 projects in 35 states. We have increased our staff to more than 120 highly skilled tradespeople, office personnel and management professionals. G. I. Construction more accurately defines who we are today: the single source general contractor for well known companies seeking consistent and uniform construction services at multiple locations throughout the Midwest.
