(ABC 6 News) – Construction crews are hard at work pouring 170 trucks worth of concrete for the Andersen building.

Once the building is complete, it will expand Mayo Clinic’s Proton Beam services in the city.

“It’s one of those milestone projects that you remember for the rest of your life,” Michael Johnson, Project Manager for Knutson Construction said.

The $200 million project broke ground last year.

As the days pass, the project continues to take shape.

“Where we’re at today, we’re basically 20 feet up from the bottom of our excavation,” Johnson said.

40 construction workers have a shared vision, getting through any obstacle the project throws at them.

“We have to keep the temperature of the concrete consistent that’s the biggest challenge,” Johnson said.

Because when all is said and done, proton beam therapy services will be expanded upon in the Med City.

According to Mayo Clinic, Proton Beam Therapy uses pencil beam scanning, allowing healthcare professionals to deliver precise radiotherapy to cancerous tissue.

This, in turn, reduces the negative side effects for patients receiving treatment.

“Reduction in toxicity is something that was meaningful for their tumor and that the improvements and outcome that we’re saving it and making sure we’re using it for the patients who could have the most improvements in their outcomes or cure rates,” said Dr. Nadia Laack, the vice-chair for Department of Radiation-Children’s Oncology at Mayo Clinic.

A dream for better care is finally within reach.

“We’ve had a lot of planning and meeting with the design stage to make it to this point,” Johnson said.

900 additional patients could be treated when this is complete in 2027.

The project is managed by Knutson Construction.
