20 • ROCK products • September 2017 QUARRY FLOOR K raemer Mining and Materials lies right outside of the Minneapolis-St. Paul metro area in Burnsville, Minn., adjacent to I-35 and the Minnesota River. In operation since 1959, the 500-acre limestone quarry produces dry screened and crushed rock in addition to a plethora of washed products. One of the few limestone producers in the area, Kraemer has provided material for a number of high-profile projects throughout the years, including the construction of the Mall of America in 1992 and numerous metro interstate, bridge and airport improvements. For more than 20 years, Dave Edmunds, executive vice pres- ident and chief operating officer of Kraemer, had a vision for the company's Burnsville quarry. He wanted to see all oper- ations moved to one location on the floor of the pit. In 2014, John Rivisto was hired as vice president and general manager of Kraemer. Edmunds immediately entrusted his vision to Rivisto and handed him the reigns to manage the project. "We could not continue to mine for 20 or 30 years hauling product up to the rim of the quarry and hauling product back down to the floor of the quarry constantly," said Rivisto.
