Len Swederski Construction was formed in 1985 and incorporated in Illinois as Swederski Concrete Construction Inc, (SCCI) in 1993. As our business grew it became evident that to be successful in the industry we needed to do things better than our competition and offer our customers and employees something special. We have accomplished this by providing our employees fair wages, occupational training, a safe and drug/alcohol free work place, company paid health, dental and life insurance, retirement and profit sharing, and providing them the best and most advanced equipment available to do their job. This in turn provides value to our customers and has lead to the development of long term relationships.

Our family and community have always been a part of our business, as our business is integral to our family and community. My wife Patti and I began the business out of our home and used a local farm as our construction yard. A few years later we moved into our present location in Spring Grove, IL.

Foundation wall and footing construction is precise and efficient utilizing two 16 ton telescoping boom trucks, an extensive array of aluminum and patented wall forming systems and total station layout systems.  Heavy industrial and commercial work is our specialty. SCCI has completed foundations for some of the largest open die type forge presses in the United States.  Use of innovative forming concepts and modern concrete mix designs have provided our customers with high quality products, efficiently constructed.  

Exterior concrete paving is our specialty. In 1999 SCCI purchased its first Somero Laser Screed and later installed a 3-D profiler system. With this equipment SCCI realized an efficient way to place exterior concrete flatwork. Two additional 3-D laser screeds and slip-form paving equipment have been added to our exterior concrete paving division.  Since then SCCI has been making great strides in expanding the concrete parking lot and local concrete street market in Northern IL. and Southern WI. With environmental issues in the forefront today and oil prices rising, concrete paving provides an environmentally friendly alternative to asphalt paving, at a reduced overall cost.  SCCI is a major player in the concrete parking lot market and can complete any size project in record time using our 3-D laser screeds in combination with our slip-form paving equipment. A large portion of our local concrete, street and parking lot market is derived from converted asphalt designs to concrete by educating the owner/user on the benefits and life cycle costs of concrete. 

Interior flatwork and industrial floors are constructed with quality and speed exceeding the expectations of owners and contractors. We have extensive experience in steel and synthetic fiber reinforced floors.  Meeting flatness/levelness (Ff/FL ) specifications can be accomplished with planning. Our equipment includes laser screeds, truss screeds, finishing machines, riding trowels and early entry saws (Soff-Cut) for any demand.

Training is important in our industry due to increased demands on managers/supervisors, technological advances in systems and equipment and reduced availability of labor coming into the construction industry. As an American Concrete Institute (ACI) certified finisher/instructor and an NCCER instructor for carpentry and concrete, Len Swederski, president of SCCI, and his staff, have provided our crews the training necessary to compete for any high end job in the industry. The percentage of our employees that have ACI certification is probably larger than any in the United States. Through the Associated Builders and Contractors (ABC), Len has volunteered the time to teach ACI classes and provide ACI Certified Finisher exams for hundreds of union and merit shop tradesman in IL and WI within the last 10 years.

Safety is always a priority at SCCI. We currently employ a full time HR/Safety person. Our investment in Safety has paid off with hundreds of thousands of dollars in insurance premium savings and reduced lost time accidents over the years. Our safety savings is returned to our workforce by way of our profit sharing program and through special incentives. Our NCCI modifier has been at or below the industry average for over a decade. In 2003, the NCCI rate was at .72. The industry average is set at 1.0.

Drug and Alcohol testing was initiated in 1993 when SCCI became one of the pioneers in the construction industry to implement a zero tolerance drug/alcohol use in the workplace. An Employee Assistance Program and services is provided for our employees. See our Safety page for more information on our policies and awards.
