Construction on Froedtert Hospital's $117 million expansion is scheduled to begin this week after archeologists finished excavating more than 1,300 human remains from unmarked graves, according to the Business Journal.

The expansion is scheduled for a fall 2015 completion, according to the Business Journal.

Froedtert Hospital's plans for a new 480,000-square-foot building to house expanded surgical, inpatient and outpatient care is proposed to stand atop what is now a cemetery containing the remains of at least 1,300 people.
