L.G. Roloff Construction (“Roloff Construction”) was founded in 1975, by Lorenze G. “Larry” Roloff in Louisville, NE.  With an office on the dining room table, one pickup truck, a few dedicated employees and a rented excavator, the company soon developed a reputation for dependability, quality, innovation and problem solving.  In 1977, the first office and shop was built near Louisville and the company grew its operations steadily, building hundreds of sanitary sewer, storm sewer and clean water systems and structures throughout the greater Omaha/Council Bluffs metropolitan area and surrounding rural communities in Nebraska and Iowa.   

In 1993 the company added concrete paving to its list of core competencies.   The company grew rapidly through the mid to late nineties and becoming a leading contractor in the City of Omaha’s combined sewer separation program (now known as the CSO program).  In 1999, the company moved to its current location in southwest Omaha, near I-80 and 144th St.  In 2004 the partnership team of employees Monty & Kara (Roloff) Habrock, Bob Norris and Ron Siwa purchased the company from Larry.   

Larry will never really retire, he says “how can I retire when I’ve never really worked a day in my life” – he loves the industry and doesn’t consider it work, he considers it fun!  Larry still carries the title of President.  Kara Habrock, Larry’s daughter, is Vice President & General Manager.  Monty Habrock is Vice President of Estimating and Project Management, Bob Norris is Vice-President and Chief Operations Officer and Ron Siwa is Vice President and Chief Financial Officer. 

In 2014, the company’s leaders made the decision to diversify and get into the commercial construction market.  They purchased a 75% stake in Phoenix Construction Group and in 2016 purchased the remaining shares and began operating the commercial construction company as the Roloff Building Group.
