BSI Constructors is proud and humbled to have celebrated its 40th Anniversary this past December.  To commemorate the anniversary, Joe Shaughnessy, Founder and Chairman of BSI, welcomed back former Co-Founder, Lorry Bannes, and the original crew of BSI including:  Carl Cooper, Head of Contracting, Sherwood Hughes, Controller, and Bernie Duda, Head of Estimating.  

Founded on December 18, 1972, Lorenz T. Bannes and Joseph F. Shaughnessy left their positions at a respected St. Louis general contractor to form Bannes-Shaughnessy, Incorporated. The company grew slowly but steadily, quietly building a reputation for quality and integrity, and for the ability to deliver unique building projects.  After a successful sixteen year run at Bannes-Shaughnessy, Bannes sold his stock to Joe Shaughnessy who then became sole owner of the company. To signal the change in the ownership structure, while retaining the same identity, the company was renamed BSI Constructors. Also at about that time, Joe Shaughnessy’s two oldest sons, Paul and Jim, joined the company in March and May, respectively, of 1989. The company is wholly owned by the Shaughnessy Family.
