Learn More About Us

LCI has been working to better communities since 1907.  Now, Four generations of Civil Engineers later we continue the same mission of completing on time and within budget quality projects.  We continue to make community and environmental sustainability our number one priorities.  Community commitment starts with our unionized staff of employees.  LCI strives for zero accidents and continues to maintain an EMR well below industry average.  Our environmental sustainability commitment starts with our investment of a material recycling plant, which allows us to offer customers a material cost decrease while helping to lower our carbon footprint.  LCI focuses on a win-win customer relationship; we win only when our customer wins.

LCI is ready to complete any project that requires; Construction Management, Concrete Roadways, Pipe Installation, Site Work, Demolition, Rock supply, Hauling.  Please contact our Estimating Department to get an estimate on your next project.

LCI is committed to the safety, health, and growth of the communities we impact.  The owners of LCI volunteer and sit on many diverse boards such as: Developmental Association of Rock Island, Construction Research Committee, Junior Board of Rock Island, Rotary, BankOrion, and General Contractors Association.  While working on a project, we make it a mission to attend all community information meetings.  Our company has been recognized with a key to the city from the city of Rock Island.

We have purchased a concrete recycling plant.  The plant allows LCI to turn concrete into rock to be used on the same project.  This decreases trucking, and therefore CO2 emissions, from the removal of the concrete off site and new material on-site.  This also decreases the need to extract new material from our earth and decreases the amount of waste in our landfills.

LCI is committed to recycling any material.  Materials such as steel are filtered out and taken to recycling plants.

LCI only allows state of the art equipment in their fleet.  State of the art equipment adheres to the toughest emissions laws.

New slogan:  “Safety Always”  We continually have an EMR below .96 with our 2016 EMR at a .77, well below industry average.

We invest annually in our safety program and equipment.  Continuously improving and staying current with the newest safety equipment.
