About SIBA

The Southern Illinois Builders Association (SIBA) represents the contractors who perform the majority of all non-residential construction in the 39 counties of Southern Illinois.  It’s often said that SIBA members build “everything except private homes” but then some members do build houses.

 

Established in 1945, SIBA represents over 500 construction companies throughout Southern Illinois.  SIBA is the largest regional contractor association in Illinois.

 

Contractor members range in size from small, closely-held firms doing less than $250,000 volume per year, up to companies performing several million dollars in volume.

 

SIBA has physical plans rooms available to its members at two office locations (O’Fallon and Marion) and also has an electronic plan room service for estimating purposes.  Members have access to the plans rooms 24 hours a day, 7 days a week.  The Weekly Bidders News service, which is sent to all members, tracks over 1,500 projects per year in Southern Illinois. 

 

SIBA is a full service Chapter of the Associated General Contractors of America serving contractors assisting in the areas of labor relations, safety, education, construction development, EEO and representation with awarding agencies.

 

SIBA Mission Statement:  The purpose of the Southern Illinois Builders Association is to advance the construction industry through strengthening our members by enabling them to do collectively what they cannot accomplish on their own.  We offer a full range of services and programs to provide value to our members as “the voice of the construction industry in Southern Illinois”.
