Mullins Cheese

Knowlton, WI

In 1970, Bill Mullin’s dad bought two cheese plants in central Wisconsin. With this addition, Mullins Cheese spans two plants in Knowlton and Marshfield, processing 15 truckloads of cheese a day. The new facility was built to process four and half million pounds of milk a day, while the old line that’s been there since 1970 was built to run two and a half million.

Already the largest family owned and operated cheese factory in Wisconsin, the new addition to Mullins Cheese in Knowlton has further expanded the company. Altogether, it processes seven million pounds of milk at the facility in Knowlton, creating just a few of people’s favorite cheeses.

Precast installation began in July, 2015 and the field services crew stayed on schedule, sometimes working beyond a normal workweek, to complete the job. Included in the precast construction were 1,213 concrete pieces – beams, columns, solid flat slabs, insulated wall panels – that were hauled to the job site and installed.

Although the project was no more challenging for the field crew than any other project, certain obstacles needed to be overcome, including sequencing the product with the dryer equipment schedule to avoid additional mobilization costs.

There were also multiple rigging scenarios for both the stainless steel and precast in coordinating around tanks and equipment. In addition, crews installed precast up to 100 ft. (30.5 m) in the air during winter weather conditions. Each level of structure required crews to leave panels out for access, and which were installed later.
