Norton Healthcare Inc. has selected Messer Construction Co. as the construction manager for its planned $107 million upgrade and expansion of Norton Audubon Hospital.

Construction of the project will be managed by the Louisville office of Messer, which is headquartered in Cincinnati.

Messer has worked with Norton before on other projects, including building Norton Brownsboro Hospital and a $70 million renovation project at Kosair Children’s Hospital.

Construction work at Audubon, off Poplar Level Road in Louisville, is expected to begin in spring of 2016.

Plans for the hospital include building a two-story addition to support 74 private patient beds, remodeling existing patient rooms, and upgrading and expanding the emergency department, intensive care unit and open heart unit.

Three operating rooms will be added, and the existing one will be renovated. The hospital will also get a new front entrance, a retail pharmacy, a cafe and a gift shop. Registration, currently done at both the main entrance and the emergency department, will be consolidated to one location. Renovations will take about three and a half years to complete.
