Where We Work

Our Headquarters

 BSI Constructors headquarters is located in the southwestern part of the City of St. Louis at 6767 Southwest Avenue within two miles of Highway 64/40 and less than a half mile from Highway 44 (see the map in the "Contact Us" section of this website).  This is our third location within the City since our founding in 1972, as been our home since 1987.  Our building is 30,000 square feet and includes offices, conference rooms, a cafeteria, a training room, and a bid room.  We also have a 22,000 square foot high bay warehouse (with a 30 ton overhead crane) which we use for equipment & tool storage/distribution, and for offsite fabrication to serve our projects.


Primary Market

The majority of our work is performed in the St. Louis Metropolitan area.  This includes the City and County of St. Louis as well as St. Charles County, Jefferson County and several counties in Southwestern Illinois.  We believe that general contracting is a very local business and there is no substitute for actually walking the site to make sure company standards are being met.  Directing most of our focus to projects we can drive to in a reasonably short timeframe is one of the things that enables our senior management/ownership to maintain its hands on attention with all of our projects.  In addition to our St. Louis metro work, we have had very successful projects in markets just a little farther out such as Franklin County; Cape Girardeau; Springfield, MO, and IL; Carbondale; Columbia; Jefferson City; Alton; Davenport, IA, etc...


Other Markets

While our primary focus is local, we have been very successful working in more dispersed markets when the situation dictates.  These projects have been as far away as Southern Florida and the Cayman Islands.  Two key elements of a project must exist before we will travel far outside of our home market: (1) the building type must be one we have considerable experience/expertise with, and (2) the client must be one with whom we have developed a high level of mutual trust.  With those prerequisites, we will travel virtually anywhere in the United States if we have the current capacity for the work.
