Kieffer Bros. is a hardworking and dedicated family company founded over 75 years ago. This tradition is now continuing into the third generation of ownership, with the fourth generation currently working and learning daily with a hands on approach just as the generations before them did.

Originally, Kieffer Bros. started as a small underground utility company serving farmers and local municipalities. We have since grown into a diversified construction company doing work for municipalities, general contractors, private developers, manufacturing facilities, and farmers as well. We are pre-qualified with Illinois and Indiana Departments of Transportation, Illinois Capital Development Board, and State of Indiana Public Works Projects. Our projects encompass, but are not limited to: general construction, water and wastewater treatment plants, concrete paving, structural concrete, site utilities, deep sanitary sewer, earthwork, building, rock crushing, and directional & horizontal drilling.

We can furnish you with a turnkey project and construction management if requested. Work with a complete line of professional architects, engineers and sub-contractors to insure you a quality project.

We are a safety conscious company and strive to provide a safe working environment for our employees on the job site. Due to this emphasis on safety, in 2006, we have achieved GOLD PARTNER status with OSHA. As a member of AGC of Illinois and Southern IL Builders Association, we have received several of their Safety Awards. Our company is fully insured and bonded
